GENERAL SAFETY PRECAUTIONS
Before using a new chain saw
Please read this manual carefully. Check that the cutting equipment is correctly tted and adjusted. See instructions under the heading Assembly. Refuel and start the chain saw. See the instructions under the headings Fuel Handling and Starting and Stopping. Do not use the chain saw until sufcient chain oil has reached the chain. See instructions under the heading Lubricating cutting equipment. Long-term exposure to noise can result in permanent hearing impairment. So always use approved hearing protection.

Important

IMPORTANT! The machine is only designed for cutting wood. You should only use the saw with the bar and chain combinations we recommend in the chapter Technical data. Never use the machine if you are fatigued, while under the inuence of alcohol or drugs, medication or anything that could affect your vision, alertness, coordination or judgement. Wear personal protective equipment. See instructions under the heading Personal protective equipment. Do not modify this product or use it if it appears to have been modied by others. Never use a machine that is faulty. Carry out the checks, maintenance and service instructions described in this manual. Some maintenance and service measures must be carried out by trained and qualied specialists. See instructions under the heading Maintenance. Never use any accessories other than those recommended in this manual. See instructions under the headings Cutting equipment and Technical data. CAUTION! Always wear protective glasses or a face visor to reduce the risk of injury from thrown objects. A chain saw is capable of throwing objects, such as wood chips, small pieces of wood, etc, at great force. This can result in serious injury, especially to the eyes. WARNING! Running an engine in a conned or badly ventilated area can result in death due to asphyxiation or carbon monoxide poisoning. WARNING! Faulty cutting equipment or the wrong combination of bar and saw chain increases the risk of kickback! Only use the bar/saw chain combinations we recommend, and follow the ling instructions. See instructions under the heading Technical data.
WARNING! Under no circumstances may the design of the machine be modied without the permission of the manufacturer. Always use genuine accessories. Non-authorized modications and/or accessories can result in serious personal injury or the death of the operator or others. Your warranty may not cover damage or liability caused by the use of nonauthorized accessories or replacement parts. WARNING! A chain saw is a dangerous tool if used carelessly or incorrectly and can cause serious, even fatal injuries. It is very important that you read and understand the contents of this operators manual. WARNING! The inside of the mufer contain chemicals that may be carcinogenic. Avoid contact with these elements in the event of a damaged mufer. WARNING! Long term inhalation of the engines exhaust fumes, chain oil mist and dust from sawdust can represent a health risk. WARNING! The ignition system of this machine produces an electromagnetic eld during operation. This eld may under some circumstances interfere with pacemakers. To reduce the risk of serious or fatal injury, we recommend persons with pacemakers to consult their physician and the pacemaker manufacturer before operating this machine.

Approved protective helmet Hearing protection Protective goggles or a visor Gloves with saw protection Trousers with saw protection Boots with saw protection, steel toe-cap and non-slip sole Always have a rst aid kit nearby.
Take care when using your saw and make sure the kickback zone of the bar never touches any object.

8 English

The chain brake (A) can either be activated manually (by your left hand) or automatically by the inertia release mechanism. The brake is applied when the front hand guard (B) is pushed forwards. To release the chain brake pull the front hand guard backwards, towards the front handle.
This movement activates a spring-loaded mechanism that tightens the brake band (C) around the engine drive system (D) (clutch drum).
Kickback can be very sudden and violent. Most kickbacks are minor and do not always activate the chain brake. If this happens you should hold the chain saw rmly and not let go.
The front hand guard is not designed solely to activate the chain brake. Another important feature is that it reduces the risk of your left hand hitting the chain if you lose grip of the front handle.
The way the chain brake is activated, either manually or automatically by the inertia release mechanism, depends on the force of the kickback and the position of the chain saw in relation to the object that the kickback zone of the bar strikes. If you get a violent kickback while the kickback zone of the bar is farthest away from you the chain brake is designed to be activated by the inertia in the kickback direction.
The chain brake must be engaged when the chain saw is started to prevent the saw chain from rotating.
Use the chain brake as a parking brake when starting and when moving over short distances, to reduce the risk of moving chain accidentally hitting your leg or anyone or anything close by.
If the kickback is less violent or the kickback zone of the bar is closer to you the chain brake is designed to be activated manually by the movement of your left hand.
In the felling position the left hand is in a position that makes manual activation of the chain brake impossible. With this type of grip, that is when the left hand is placed so that it cannot affect the movement

of the front hand guard, the chain brake can only be activated by the inertia action.

Throttle lockout

The throttle lockout is designed to prevent accidental operation of the throttle control. When you press the lock (A) (i.e. when you grasp the handle) it releases the throttle control (B). When you release the handle the throttle control and the throttle lockout both move back to their original positions. This arrangement means that the throttle control is automatically locked at the idle setting.

Will my hand always activate the chain brake during a kickback?
No. It takes a certain force to move the hand guard forward. If your hand only lightly touches the front guard or slips over it, the force may not be enough to trigger the chain brake. You should also maintain a rm grip of the chain saw handles while working. If you do and experience a kickback, your hand may never leave the front handle and will not activate the chain brake, or the chain brake will only activate after the saw has swung around a considerable distance. In such instances, the chain brake might not have enough time to stop the saw chain before it touches you. There are also certain positions in which your hand cannot reach the front hand guard to activate the chain brake; for example, when the saw chain is held in felling position.

Chain catcher

The chain catcher is designed to catch the chain if it snaps or jumps off. This should not happen if the chain is properly tensioned (see instructions under the heading Assembly) and if the bar and chain are properly serviced and maintained (see instructions under the heading General working instructions).
Will my inertia activated chain brake always activate during kickback in the event of a kickback?
No. First your brake must be in working order. Testing the brake is simple, see instructions under the heading Checking, maintaining and servicing chain saw safety equipment. We recommend you do before you begin each work session. Second the kickback must be strong enough to activate the chain brake. If the chain brake is too sensitive it would activate all the time which would be a nuisance.

Right hand guard

Apart from protecting your hand if the chain jumps or snaps, the right hand guard stops branches and twigs from interfering with your grip on the rear handle.
Will my chain brake always protect me from injury in the event of a kickback?
No. First, the chain brake must be in working order to provide the intended protection. Second, it must be activated during the kickback as described above to stop the saw chain. Third, the chain brake may be activated but if the bar is too close to you the brake might not have enough time to slow down and stop the chain before the chain saw hits you. Only you and proper working technique can eliminate kickback and its danger. The machines vibration damping system reduces the transfer of vibration between the engine unit/cutting equipment and the machines handle unit. The body of the

Never use waste oil. This results in damage to the oil pump, the bar and the chain. It is important to use oil of the right grade (suitable viscosity range) to suit the air temperature. In temperatures below 32F (0C) some oils become too viscous. This can overload the oil pump and result in damage to the oil pump components. Contact your service agent when choosing chain oil. 82-95 Rev.2 2009-03-23

Fueling

Move the machine at least 10 ft (3 m) from the refuelling point before starting it.
WARNING! Taking the following precautions, will lessen the risk of re: Do not smoke and do not place any hot objects in the vicinity of fuel. Always stop the engine and let it cool for a few minutes before refuelling. When refuelling, open the fuel cap slowly so that any excess pressure is released gently. Tighten the fuel cap carefully after refuelling. Always move the machine away from the refuelling area before starting. 1 Never start the machine: If you have spilled fuel or chain oil on the machine. Wipe off the spillage and allow remaining fuel to evaporate. If you have spilled fuel on yourself or your clothes, change your clothes. Wash any part of your body that has come in contact with fuel. Use soap and water. If the machine is leaking fuel. Check regularly for leaks from the fuel cap and fuel lines.
Clean the area around the fuel cap. Clean the fuel and chain oil tanks regularly. The fuel lter must be replaced at least once a year. Contamination in the tanks causes malfunction. Make sure the fuel is well mixed by shaking the container before refuelling. The capacities of the chain oil tank and fuel tank are carefully matched. You should therefore always ll the chain oil tank and fuel tank at the same time.
WARNING! Never use a machine with visible damage to the spark plug guard and ignition cable. A risk of sparking arises, which can cause a re.

Transport and storage

Always store the chain saw and fuel so that there is no risk of leakages or fumes coming into contact with sparks or naked ames from electrical equipment, electric motors, relays/switches, boilers and the like. Always store fuel in an approved container designed for that purpose. For longer periods of storage or for transport of the chain saw, the fuel and chain oil tanks should be emptied. Ask where you can dispose of waste fuel and chain oil at your local gas station. Ensure the machine is cleaned and that a complete service is carried out before long-term storage. The bar guard must always be tted to the cutting attachment when the machine is being transported or in storage, in order to prevent accident contact with the sharp chain. Even a non-moving chain can cause serious cuts to yourself or persons you bump into with an exposed chain.

As the chain brake is still engaged the speed of the engine must be set to idling as soon as possible, this is achieved by disengaging the throttle lock. Disengagement is done by gently touching on the throttle trigger. This prevents unnecessary wear to the clutch, clutch drum and brake band. drop start. This method is very dangerous because you may lose control of the saw.
Allow the machine to idle a few seconds before giving full throttle. CAUTION! Do not pull the starter cord all the way out and do not let go of the starter handle when the cord is fully extended. This can damage the machine.
Never start the machine indoors. Exhaust fumes can be dangerous if inhaled. Observe your surroundings and make sure that there is no risk of people or animals coming into contact with the cutting equipment.
Always hold the saw with both hands. The right hand should be on the rear handle, and the left hand on the front handle. All people, whether right or left handed, should use this grip. Use a rm grip with thumbs and ngers encircling the chain saw handles.
Note! Pull the front hand guard towards the front handle. The chain brake is now disengaged. Your saw is ready for use.
WARNING! Long term inhalation of the engines exhaust fumes, chain oil mist and dust from sawdust can represent a health risk.

Stopping

Never start a chain saw unless the bar, chain and all covers are tted correctly. See instructions under the heading Assembly. Without a bar and chain attached to the chain saw the clutch can come loose and cause serious injury. Stop the engine by switching off the ignition.
The chain brake should be activated when starting. Se instructions under the heading Start and stop. Do not

WORKING TECHNIQUES

Before use:

Basic safety rules
1 Look around you: To ensure that people, animals or other things cannot affect your control of the machine. To make sure that none of the above might come within reach of your saw or be injured by falling trees.
Check that the chain brake works correctly and is not damaged. Check that the rear right hand guard is not damaged. Check that the throttle lockout works correctly and is not damaged. Check that the stop switch works correctly and is not damaged. Check that all handles are free from oil. Check that the anti vibration system works and is not damaged. Check that the mufer is securely attached and not damaged. Check that all parts of the chain saw are tightened correctly and that they are not damaged or missing. Check that the chain catcher is in place and not damaged. CAUTION! Follow the instructions above, but do not use a chain saw in a situation where you cannot call for help in case of an accident. 2 Do not use the machine in bad weather, such as dense fog, heavy rain, strong wind, intense cold, etc. Working in bad weather is tiring and often brings added risks, such as icy ground, unpredictable felling direction, etc. Take great care when removing small branches and avoid cutting bushes (i.e. cutting many small branches at the same time). Small branches can be grabbed by the chain and thrown back at you, causing serious injury.

Never use the chain saw above shoulder height and avoid cutting with the tip of the bar. Never use the chain saw one-handed!
In order to keep control of your saw, always maintain a rm foothold. Never work on a ladder, in a tree or on any other insecure support.
Most kickback accidents happen during limbing. Make sure you are standing rmly and that there is nothing in the way that might make you trip or lose your balance. Lack of concentration can lead to kickback if the kickback zone of the bar accidentally touches a branch, nearby tree or some other object. Always use a fast cutting speed, i.e. full throttle. Take great care when you cut with the top edge of the bar, i.e. when cutting from the underside of the object. This is known as cutting with a pushing chain. The chain tries to push the chain saw back towards the

English 25

user. If the saw chain is jamming, the saw may be pushed back at you. Terms Cutting = General term for cutting through wood. Limbing = Cutting branches off a felled tree. Splitting = When the object you are cutting breaks off before the cut is complete. There are ve important factors you should consider before making a cut: 8 Unless the user resists this pushing force there is a risk that the chain saw will move so far backwards that only the kickback zone of the bar is in contact with the tree, which can lead to a kickback. 1 Make sure the cutting equipment will not jam in the cut.
Make sure the object you are cutting will not split.
Cutting with the bottom edge of the bar, i.e. from the top of the object downwards, is known as cutting with a pulling chain. In this case the chain saw pulls itself towards the tree and the front edge of the chain saw body rests naturally on the trunk when cutting. Cutting with a pulling chain gives the operator better control over the chain saw and the position of the kickback zone.
Make sure the chain will not strike the ground or any other object during or after cutting.
Is there a risk of kickback?
Follow the instructions on sharpening and maintaining your bar and chain. When you replace the bar and chain use only combinations that are recommended by us. See instructions under the headings Cutting equipment and Technical data.
Do the conditions and surrounding terrain affect how safely you can stand and move about?

Basic cutting technique

General
WARNING! Never use a chain saw by holding it with one hand. A chain saw is not safely controlled with one hand. Always have a secure, rm grip around the handles with both hands.

Two factors decide whether the chain will jam or the object that you are cutting will split: the rst is how the object is supported before and after cutting, and the second is whether it is in tension. In most cases you can avoid these problems by cutting in two stages; from the top and from the bottom. You need to support the object so that it will not trap the chain or split during cutting. IMPORTANT! If the chain jams in the cut: stop the engine! Dont try to pull the chain saw free. If you do you may be injured by the chain when the chain saw suddenly breaks free. Use a lever to open up the cut and free the chain saw. The following instructions describe how to handle the common situations you are likely to encounter when using a chain saw.
Always use full throttle when cutting! Reduce the speed to idle after every cut (running the engine for too long at full throttle without any load, i.e. without any resistance from the chain during cutting, can lead to serious engine damage). Cutting from above = Cutting with a pulling chain. Cutting from below = Cutting with pushing chain. Cutting with a pushing chain increases the risk of kickback. See instructions under the heading How to avoid kickback. 26 English
Limbing When limbing thick branches you should use the same approach as for cutting. Cut difcult branches piece by piece. If it is possible (can you turn the log?) stop cutting about 2/3 of the way through the log.
Turn the log and nish the cut from the opposite side.

Cutting

The log is supported at one end. There is a high risk that it will split. WARNING! Never attempt to cut logs while they are in a pile or when a couple of logs are lying together. Such procedures drastically increase the risk of kickback which can result in a serious or fatal injury. Start by cutting from below (about 1/3 of the way through).
If you have a pile of logs, each log you attempt to cut should be removed from the pile, placed on a saw horse or runners and cut individually. Remove the cut pieces from the cutting area. By leaving them in the cutting area, you increase the risk for inadvertently getting a kickback, as well as increasing the risk of losing your balance while working.
Finish by cutting from above so that the two cuts meet.
The log is supported at both ends. There is a high risk that the chain will jam.
Start by cutting from above (about 1/3 of the way through). The log is lying on the ground. There is little risk of the chain jamming or the object splitting. However there is a risk that the chain will touch the ground when you nish the cut.

Make one or more cuts at or near the point of maximum tension. Make as many cuts of sufcient depth as necessary to reduce the tension and make the tree or branch break at the point of maximum tension.
Never cut straight through a tree or branch that is in tension! Never work in the risk zone of the hanging trapped tree. If you must cut across tree/limb, make two to three cuts, one inch apart, one to two inches deep.
Continue to cut deeper until tree/limb bends and tension is released.

30 English

Cut tree/limb from outside the bend, after tension has been released. Limbing

How to avoid kickback

WARNING! Kickback can happen very suddenly and violently; kicking the chain saw, bar and chain back at the user. If this happens when the chain is moving it can cause very serious, even fatal injuries. It is vital you understand what causes kickback and that you can avoid it by taking care and using the right working technique.
WARNING! A majority of kickback accidents occur during limbing. Do not use the kickback zone of the guide bar. Be extremely cautious and avoid contacting the log, other limbs or objects with the nose of the guide bar. Be extremely cautious of limbs under tension. They can spring back toward you and cause loss of control resulting in injury.

What is kickback?

The word kickback is used to describe the sudden reaction that causes the chain saw and bar to jump off an object when the upper quadrant of the tip of the bar, known as the kickback zone, touches an object.
Make sure that you can stand and move about safely. Work on the left side of the trunk. Work as close as possible to the chain saw for maximum control. If possible, let the weight of the chain saw rest on the trunk.
Kickback always occurs in the cutting plane of the bar. Normally the chain saw and bar are thrown backwards and upwards towards the user. However, the chain saw may move in a different direction depending on the way it was being used when the kickback zone of the bar touched the object.
Keep the trunk between you and the chain saw as you move along the trunk. Cutting the trunk into logs See instructions under the heading Basic cutting technique.
Kickback only occurs if the kickback zone of the bar touches an object.

MAINTENANCE

General

The user must only carry out the maintenance and service work described in this manual. More extensive work must be carried out by an authorised service workshop.
Basic settings and running in
The basic carburetor settings are adjusted during testing at the factory. Avoid running at a too high speed for extended periods during the rst 10 hours. CAUTION! If the chain rotates while idling the T-screw must be turned anti-clockwise until the chain stops. Rec. idle speed: 2700 rpm

Carburetor adjustment

Due to existing environmental and emissions legislation your chain saw is equipped with movement limiters on the carburetor adjuster screws. These limit the adjustment possibilities to a maximum of a 1/2 turn.

Fine adjustment

When the machine has been run-in the carburetor should be nely adjusted. The ne adjustment should be carried out by a qualied person. First adjust the Ljet, then the idling screw T and then the H-jet.

Conditions

1/2 1/2
Your Husqvarna product has been designed and manufactured to specications that reduce harmful emissions.

Function

The carburetor governs the engines speed via the throttle control. Air and fuel are mixed in the carburetor. The air/fuel mixture is adjustable. Correct adjustment is essential to get the best performance from the machine. The setting of the carburetor means that the engine is adapted to local conditions, for example, the climate, altitude, fuel and the type of 2-stroke oil. The carburetor has three adjustment controls: - L = Low speed jet - H = High speed jet - T = Idle adjustment screw
The L and H-jets are used to adjust the supply of fuel to match the rate that air is admitted, which is controlled with the throttle. If they are screwed clockwise the air/fuel ratio becomes leaner (less fuel) and if they are turned anti-clockwise the ratio becomes richer (more fuel). A lean mixture gives a higher engine speed and a rich mixture gives a lower engine speed. The T-screw regulates the throttle setting at idle speed. If the T-screw is turned clockwise this gives a higher idle speed; turning it anti-clockwise gives a lower idle speed.

32 English

Before any adjustments are made the air lter should be clean and the cylinder cover tted. Adjusting the carburetor while a dirty air lter is in use will result in a leaner mixture next time the lter is cleaned. This can give rise to serious engine damage. Do not attempt to adjust the L and H jets beyond either stop as this could cause damage. Now start the machine according to the starting instructions and let it warm up for 10 minutes. Place the machine on a at surface so that the bar points away from you and so that the bar and chain do not come into contact with the surface or other objects.

Low speed jet L

Brush off any wood dust, resin and dirt from the chain brake and clutch drum. Dirt and wear can impair operation of the brake. Checking the brake trigger Place the chain saw on rm ground and start it. Make sure the chain does not touch the ground or any other object. See the instructions under the heading Start and stop.
Regularly check that the brake band is at least 0.024 inch (0.6 mm) thick at its thinnest point. Checking the front hand guard
Make sure the front hand guard is not damaged and that there are no visible defects such as cracks.
Grasp the chain saw rmly, wrapping your ngers and thumbs around the handles.

English 33

Apply full throttle and activate the chain brake by tilting your left wrist forward onto the front hand guard. Do not let go of the front handle. The chain should stop immediately.
Check that the chain catcher is not damaged and is rmly attached to the body of the chain saw.
Make sure the throttle control is locked at the idle setting when the throttle lockout is released.
Press the throttle lockout and make sure it returns to its original position when you release it.
Check that the right hand guard is not damaged and that there are no visible defects, such as cracks.
Check that the throttle control and throttle lockout move freely and that the return springs work properly.
Regularly check the vibration damping units for cracks or deformation.
Start the chain saw and apply full throttle. Release the throttle control and check that the chain stops and remains stationary. If the chain rotates when the throttle control is in the idle position you should check the carburetor idle adjustment.
Make sure the vibration damping units are securely attached to the engine unit and handle unit.

34 English

use a mufer if the spark arrestor screen is missing or defective.
Start the engine and make sure the engine stops when you move the stop switch to the stop setting.
The mufer is designed to reduce the noise level and to direct the exhaust gases away from the operator. The exhaust gases are hot and can contain sparks, which may cause re if directed against dry and combustible material.

Starter

Never use a machine that has a faulty mufer.
WARNING! When the recoil spring is wound up in the starter housing it is under tension and can, if handled carelessly, pop out and cause personal injury. Care must be exercised when replacing the return spring or the starter cord. Wear protective glasses and protective gloves.
Changing a broken or worn starter cord
Regularly check that the mufer is securely attached to the machine. Loosen the screws that hold the starter against the crankcase and remove the starter.
Some mufers are equipped with a special spark arrestor screen. If your machine has this type of mufer, you should clean the screen at least once a week. This is best done with a wire brush. A blocked screen will cause the engine to overheat and may lead to serious damage. Note! The screen must be replaced if it is damaged. If the screen is blocked the machine will overheat and this will cause damage to the cylinder and piston. Never use a machine with a mufer that is in poor condition. Never

The spark plug condition is inuenced by: Incorrect carburetor adjustment. An incorrect fuel mixture (too much or incorrect type of oil). A dirty air lter.
The clutch drum has a needle bearing on the output shaft. This needle bearing must be lubricated regularly (once a week). When lubricating, remove the clutch cover by loosening the two bar nuts. Lay the saw on its side with the clutch drum upwards. Lubrication involves engine oil dripping into the centre of the clutch drum as it rotates.
These factors cause deposits on the spark plug electrodes, which may result in operating problems and starting difculties. If the machine is low on power, difcult to start or runs poorly at idle speed: always check the spark plug rst before taking any further action. If the spark plug is dirty, clean it and check that the electrode gap is 0.020 inch (0.5 mm). The spark plug should be replaced after about a month in operation or earlier if necessary.
Adjustment of the oil pump
Note! Always use the recommended spark plug type! Use of the wrong spark plug can damage the piston/cylinder. Check that the spark plug is tted with a suppressor.
Adjustments are made by turning the screw using a screwdriver or combination spanner. The machine is supplied from the factory with the screw set to position 2. Turning the screw clockwise will reduce the oil ow and turning the screw anti-clockwise will increase the oil ow.
Lubricating the bar tip sprocket
Lubricate the bar tip sprocket each time you refuel. Use the special grease gun and a good quality bearing grease. Recommended settings: Bar 13"-15": Position 1 Bar 15"-18": Position 2 Bar 18"-20": Position 3 These recommendations apply to Husqvarnas chain oil, for other chain oils increase the oil ow by one step.
WARNING! The engine must be stopped when making adjustments.

Cooling system
Temperature 0C (32F) or colder:
To keep the working temperature as low as possible the machine is equipped with a cooling system. The cooling system consists of: 1 Air intake on the starter. 2 Air guide plate. 3 Fins on the ywheel. 4 Cooling ns on the cylinder. 5 Cylinder cover (directs cold air over the cylinder).
The cylinder cover is designed so it can be adjusted for running in cold weather, so that preheated air from the cylinder can pass into the carburetor space preventing icing of the air lter, etc.
Temperature -5C (23F) or colder:

Do not operate a chain saw when you are fatigued. Use safety footwear; snug-tting clothing, protective gloves, and eye, hearing and head protection devices. Use caution when handling fuel. Move the chain saw at least 10 feet (3 m) from the fueling point before starting the engine. Do not allow other persons to be near the chain saw when starting or cutting with the chain saw. Keep bystanders and animals out of the work area. Do not start cutting until you have a clear work area, secure footing and a planned retreat path from the falling tree. Keep all parts of your body away from the saw chain when the engine is running. Before you start the engine, make sure that the saw chain is not contacting anything. Carry the chain saw with the engine stopped, the guide bar and saw chain to the rear, and the mufer away from your body. Do not operate a chain saw that is damaged, improperly adjusted, or not completely and securely assembled. Be sure that the saw chain stops moving when the throttle control trigger is released. Shut off the engine before setting the chain saw down. Use extreme caution when cutting small size brush and saplings because slender material may catch the saw chain and be whipped toward you or pull you off balance. When cutting a limb that is under tension be alert for springback so that you will not be struck when the tension in the wood bers is released. Keep handles dry, clean and free of oil or fuel mixture. Operate the chain saw only in well-ventilated areas. Do not operate a chain saw in a tree unless you have been specically trained to do so. Do not operate a chain saw above shoulder height. All chain saw service, other than the items listed in the operators/owners safety and maintenance instructions, should be performed by competent chain saw service personnel. (For example, if improper tools are used to remove the ywheel or if an improper tool is used to hold the ywheel in order to remove the clutch, structural damage to the ywheel could occur and subsequently cause the ywheel to burst.) When transporting your chain saw, use the appropriate guide bar guard. Note: This Annex is intended primarily for the consumer or occasional user.

INTRODUCTION

Dear customer!

Congratulations on your choice to buy a Husqvarna product! Husqvarna is based on a tradition that dates back to 1689, when the Swedish King Karl XI ordered the construction of a factory on the banks of the Huskvarna River, for production of muskets. The location was logical, since water power was harnessed from the Huskvarna River to create the waterpowered plant. During over 300 years of continuous operation, the Husqvarna factory has produced a lot of different products, from wood stoves to modern kitchen appliances, sewing machines, bicycles, motorcycles etc. In 1956, the rst motor driven lawn mowers appeared, followed by chain saws in 1959, and it is within this area Husqvarna is working today. Today Husqvarna is one of the leading manufacturers in the world of forest and garden products, with quality as our highest priority. We develop, manufacture and market high quality motor driven products for forestry and gardening as well as for building and construction industry. Your purchase gives you access to professional help with repairs and service whenever this may be necessary. If the retailer who sells your machine is not one of our authorized dealers, ask for the address of your nearest servicing dealer. It is our wish that you will be satised with your product and that it will be your companion for a long time. Think of this operators manual as a valuable document. By following its content (using, service, maintenance etc) the life span and the second-hand value of the machine can be extended. If you ever lend or sell this machine, make sure that the borrower or buyer gets the operators manual, so they will also know how to properly maintain and use it.

To reduce the risk of serious or fatal injury, we recommend persons with medical implants to consult their physician and the medical implant manufacturer before operating this machine.

Always use common sense

It is not possible to cover every conceivable situation you can face when using a chain saw. Always exercise care and use your common sense. Avoid all situations which you consider to be beyond your capability. If you still feel uncertain about operating procedures after reading these instructions, you should consult an expert before continuing. Do not hesitate to contact your dealer or us if you have any questions about the use of the chain saw. We will willingly be of service and provide you with advice as well as help you to use your chain saw both efciently and safely. Attend a training course in chain saw usage if English 7
possible. Your dealer, forestry school or your library can provide information about which training materials and courses are available. Generally clothes should be close-tting without restricting your freedom of movement. IMPORTANT! Sparks can come from the mufer, the bar and chain or other sources. Always have re extinguishing tools available if you should need them. Help prevent forest res.

The way the chain brake is activated, either manually or automatically by the inertia release mechanism, depends on the force of the kickback and the position of the chain saw in relation to the object that the kickback zone of the bar strikes. If you get a violent kickback while the kickback zone of the bar is farthest away from you the chain brake is designed to be activated by the inertia in the kickback direction.
The chain brake must be engaged when the chain saw is started to prevent the saw chain from rotating.
Use the chain brake as a parking brake when starting and when moving over short distances, to reduce the risk of moving chain accidentally hitting your leg or anyone or anything close by.
If the kickback is less violent or the kickback zone of the bar is closer to you the chain brake is designed to be activated manually by the movement of your left hand.
To release the chain brake pull the front hand guard backwards, towards the front handle.
In the felling position the left hand is in a position that makes manual activation of the chain brake impossible. With this type of grip, that is when the left hand is placed so that it cannot affect the movement of the front hand guard, the chain brake can only be activated by the inertia action.

English 9

Will my hand always activate the chain brake during a kickback?
No. It takes a certain force to move the hand guard forward. If your hand only lightly touches the front guard or slips over it, the force may not be enough to trigger the chain brake. You should also maintain a rm grip of the chain saw handles while working. If you do and experience a kickback, your hand may never leave the front handle and will not activate the chain brake, or the chain brake will only activate after the saw has swung around a considerable distance. In such instances, the chain brake might not have enough time to stop the saw chain before it touches you. There are also certain positions in which your hand cannot reach the front hand guard to activate the chain brake; for example, when the saw chain is held in felling position.

ASSEMBLY
Fitting the bar and chain
Tension the chain by turning the chain tensioning screw clockwise using the combination spanner. The chain should be tensioned until it does not sag from the underside of the bar.
WARNING! Always wear gloves, when working with the chain.
Check that the chain brake is in disengaged position by moving the front hand guard towards the front handle. The chain is correctly tensioned when it does not sag from the underside of the bar, but can still be turned easily by hand. Hold up the bar tip and tighten the bar nuts with the combination spanner.
Remove the bar nuts and remove the clutch cover (chain brake). Take off the transportation ring (A). When tting a new chain, the chain tension has to be checked frequently until the chain is run-in. Check the chain tension regularly. A correctly tensioned chain ensures good cutting performance and long life.

FUEL HANDLING
Note! The machine is equipped with a two-stroke engine and must always be run using a mixture of gasoline and two-stroke oil. It is important to accurately measure the amount of oil to be mixed to ensure that the correct mixture is obtained. When mixing small amounts of fuel, even small inaccuracies can drastically affect the ratio of the mixture. Mixing ratio 1:50 (2%) for all engines. Gasoline, litre Two-stroke oil, litre 2% (1:50) 15 0,10 0,20 0,30 0,40 US. oz. 2 1/1/7/8
WARNING! Always ensure there is adequate ventilation when handling fuel.

20 US gallon 1/2 5

Gasoline
Use good quality unleaded gasoline. CAUTION! Engines equipped with catalytic converters must be run on unleaded fuel mixtures. Leaded gasoline will destroy the catalytic converter and it will no longer serve its purpose. The green fuel cap on saws tted with catalytic converters means that only unleaded gasoline can be used. The lowest recommended octane grade is 87 ((RON+MON)/2). If you run the engine on a lower octane grade than 87 so-called knocking can occur. This gives rise to a high engine temperature and increased bearing load, which can result in serious engine damage. When working with continuous high revs (e.g. limbing) a higher octane is recommended.

Mixing

Environment fuel HUSQVARNA recommends the use of alkylate fuel or environmental fuel for four-stroke engines blended with two-stroke oil as set out below. Note that carburetor adjustment may be necessary when changing the type of fuel (see instructions under the heading Carburetor). Running-in Avoid running at a too high speed for extended periods during the rst 10 hours.

Pull the starter handle (D): Pull the starter handle with your right hand and pull out the starter cord slowly until you feel a resistance (as the starter pawls engage) then pull rmly and rapidly until the engine res. Push in the choke control as soon as the engine res which can be heard through a "puff" sound. Keep on pulling the cord powerfully until the engine starts.

Warm engine

Ignition; choke (A): The correct choke/start throttle setting for warm starting is obtained by moving the choke control to the choke position and then pushing it in again.
Starting: The chain brake should be activated when starting the chain saw. Activate the chain brake by pushing the front hand guard forwards.

Cold engine

Stopswitch; choke (A): Set the choke control in the choke position by pull the choke control outwards. This automatically sets the stop switch to the start position. Air purge (B): Press the air purge repeatedly (at least 6 times) until fuel begins to ll the bulb. The bulb need not be completely lled.
Start throttle: The correct choke/start throttle setting is obtained by moving the control as stated above. Air purge (B): Press the air purge repeatedly (at least 6 times) until fuel begins to ll the bulb. The bulb need not be completely lled. Decompression valve (C): Press the valve to reduce the pressure in the cylinder and make starting easier. You should always use the decompression valve when starting the machine. Once the machine has started the valve will automatically return to its original setting. Pull the starter handle (D): Pull the starter handle with your right hand and pull out the starter cord slowly until you feel a resistance (as the starter pawls engage) then pull rmly and rapidly until the engine res.

English 21

As the chain brake is still engaged the speed of the engine must be set to idling as soon as possible, this is achieved by disengaging the throttle lock. Disengagement is done by gently touching on the throttle trigger. This prevents unnecessary wear to the clutch, clutch drum and brake band. The chain brake should be activated when starting. Se instructions under the heading Start and stop. Do not drop start. This method is very dangerous because you may lose control of the saw.
Allow the machine to idle a few seconds before giving full throttle. CAUTION! Do not pull the starter cord all the way out and do not let go of the starter handle when the cord is fully extended. This can damage the machine.
Never start the machine indoors. Exhaust fumes can be dangerous if inhaled. Observe your surroundings and make sure that there is no risk of people or animals coming into contact with the cutting equipment.

General working instructions
IMPORTANT! This section describes basic safety rules for using a chain saw. This information is never a substitute for professional skills and experience. If you get into a situation where you feel unsafe, stop and seek expert advice. Contact your chain saw dealer, service agent or an experienced chain saw user. Do not attempt any task that you are not sure you can handle! Before using a chain saw you must understand the effects of kickback and how to avoid them. See instructions under the heading How to avoid kickback. Before using a chain saw you must understand the difference between cutting with the top and bottom edges of the bar. See instructions under the headings How to avoid kickback and Machines safety equipment. Wear personal protective equipment. See instructions under the heading Personal protective equipment.
Make sure you can move and stand safely. Check the area around you for possible obstacles (roots, rocks, branches, ditches, etc.) in case you have to move suddenly. Take great care when working on sloping ground.
Take great care when cutting a tree that is under tension. A tree that is under tension may spring back to its normal position before or after being cut. If you position yourself incorrectly or make the cut in the wrong place the tree may hit you or the machine and cause you to lose control. Both situations can cause serious personal injury.

Basic safety rules

1 Look around you: To ensure that people, animals or other things cannot affect your control of the machine. 6 Before moving your chain saw switch off the engine and lock the chain using the chain brake. Carry the chain saw with the bar and chain pointing backwards.

English 23

Fit a guard to the bar before transporting the chain saw or carrying it for any distance. Have control over the workpiece. If the pieces you intend to cut are small and light, they can jam in the saw chain and be thrown towards you. Even if this does not need to be a danger, you may be surprised and lose control of the saw. Never saw stacked logs or branches without rst separating them. Only saw one log or one piece at a time. Remove the cut pieces to keep your working area safe.
When you put the chain saw on the ground, lock the saw chain using the chain brake and ensure you have a constant view of the machine. Switch the engine off before leaving your chain saw for any length of time.
WARNING! Sometimes chips get stuck in the clutch cover causing the chain to jam. Always stop the engine before cleaning.
If you understand what kickback is and how it happens then you can reduce or eliminate the element of surprise. By being prepared you reduce the risk. Kickback is usually quite mild, but it can sometimes be very sudden and violent. Always hold the chain saw rmly with your right hand on the rear handle and your left hand on the front handle. Wrap your ngers and thumbs around the handles. You should use this grip whether you are right-handed or left-handed. This grip minimizes the effect of kickback and lets you keep the chain saw under control. Do not let go of the handles! 5

Two factors decide whether the chain will jam or the object that you are cutting will split: the rst is how the object is supported before and after cutting, and the second is whether it is in tension. In most cases you can avoid these problems by cutting in two stages; from the top and from the bottom. You need to support the object so that it will not trap the chain or split during cutting. IMPORTANT! If the chain jams in the cut: stop the engine! Dont try to pull the chain saw free. If you do you may be injured by the chain when the chain saw suddenly breaks free. Use a lever to open up the cut and free the chain saw. The following instructions describe how to handle the common situations you are likely to encounter when using a chain saw.
General Always use full throttle when cutting! Reduce the speed to idle after every cut (running the engine for too long at full throttle without any load, i.e. without any resistance from the chain during cutting, can lead to serious engine damage). Cutting from above = Cutting with a pulling chain. Cutting from below = Cutting with pushing chain. Cutting with a pushing chain increases the risk of kickback. See instructions under the heading How to avoid kickback. 1153137-95 Rev.2 2009-12-29

English 25

Limbing When limbing thick branches you should use the same approach as for cutting. Cut difcult branches piece by piece. Turn the log and nish the cut from the opposite side.
The log is supported at one end. There is a high risk that it will split.

Cutting

Start by cutting from below (about 1/3 of the way through). Finish by cutting from above so that the two cuts meet. WARNING! Never attempt to cut logs while they are in a pile or when a couple of logs are lying together. Such procedures drastically increase the risk of kickback which can result in a serious or fatal injury.
If you have a pile of logs, each log you attempt to cut should be removed from the pile, placed on a saw horse or runners and cut individually. Remove the cut pieces from the cutting area. By leaving them in the cutting area, you increase the risk for inadvertently getting a kickback, as well as increasing the risk of losing your balance while working.
The log is supported at both ends. There is a high risk that the chain will jam.
Start by cutting from above (about 1/3 of the way through). Finish by cutting from below so that the two cuts meet.
The log is lying on the ground. There is little risk of the chain jamming or the object splitting. However there is a risk that the chain will touch the ground when you nish the cut.

Tree felling technique

IMPORTANT! It takes a lot of experience to fell a tree. Inexperienced users of chain saws should not fell trees. Do not attempt any task beyond your experience level! Safe distance

Cut all the way through the log from above. Avoid letting the chain touch the ground as you nish the cut. Maintain full throttle but be prepared for what might happen.
The safe distance between a tree that is to be felled and anyone else working nearby is at least 2 1/2 tree lengths. Make sure that no-one else is in this risk zone before or during felling.
If it is possible (can you turn the log?) stop cutting about 2/3 of the way through the log.

26 English

Felling direction The aim is to fell the tree in a position where you can limb and cross-cut the log as easily as possible. You want it to fall in a location where you can stand and move about safely. Once you have decided which way you want the tree to fall you must judge which way the tree would fall naturally. Several factors affect this: Lean of the tree Bend Wind direction Arrangement of branches Weight of snow Obstacles within the reach of the tree: for example, other trees, power lines, roads and buildings. Look for signs of damage and rot in the stem, this makes it more probably that the tree will break and start to fall before you expect it to. Remove any undergrowth from the base of the tree and check the area for obstacles (stones, branches, holes, etc.) so that you have a clear path of retreat when the tree starts to fall. Your path of retreat should be roughly 135 degrees away from the intended felling direction. Clearing the trunk and preparing your retreat Delimb the stem up to shoulder height. It is safer to work from the top down and to have the tree between you and the saw.

in ell

Retreat path
You may nd you are forced to let the tree fall in its natural direction because it is impossible or dangerous to try to make it fall in the direction you rst intended. Another very important factor, which does not affect the felling direction but does affect your safety, is to make sure the tree has no damaged or dead branches that might break off and hit you during felling. The main point to avoid is letting the tree fall onto another tree. It is very dangerous to remove a trapped tree and there is high accident risk. See instructions under the heading Freeing a tree that has fallen badly.

Freeing a tree that has fallen badly
Freeing a trapped tree It is very dangerous to remove a trapped tree and there is high accident risk. Never try to fell the tree that is trapped. Never work in the risk zone of the hanging trapped tree. All control over the felling direction is lost if the felling hinge is too narrow or non-existent, or if the directional cuts and felling cut are badly placed.
The safest method is to use a winch. Tractor-mounted

How to avoid kickback

Cutting trees and branches that are in tension Preparations: Work out which side is in tension and where the point of maximum tension is (i.e. where it would break if it was bent even more).
WARNING! Kickback can happen very suddenly and violently; kicking the chain saw, bar and chain back at the user. If this happens when the chain is moving it can cause very serious, even fatal injuries. It is vital you understand what causes kickback and that you can avoid it by taking care and using the right working technique.

What is kickback?

The word kickback is used to describe the sudden reaction that causes the chain saw and bar to jump off an object when the upper quadrant of the tip of the bar, known as the kickback zone, touches an object.
Decide which is the safest way to release the tension and whether you are able to do it safely. In complicated situations the only safe method is to put aside your chain saw and use a winch. General advice: Position yourself so that you will be clear of the tree or branch when the tension is released.
Make one or more cuts at or near the point of maximum tension. Make as many cuts of sufcient depth as necessary to reduce the tension and make the tree or branch break at the point of maximum tension.
Kickback always occurs in the cutting plane of the bar. Normally the chain saw and bar are thrown backwards and upwards towards the user. However, the chain saw may move in a different direction depending on the way it was being used when the kickback zone of the bar touched the object.
Never cut straight through a tree or branch that is in tension! If you must cut across tree/limb, make two to three cuts, one inch apart, one to two inches deep. Kickback only occurs if the kickback zone of the bar touches an object.
Continue to cut deeper until tree/limb bends and tension is released.
Cut tree/limb from outside the bend, after tension has been released.

English 29

Limbing WARNING! A majority of kickback accidents occur during limbing. Do not use the kickback zone of the guide bar. Be extremely cautious and avoid contacting the log, other limbs or objects with the nose of the guide bar. Be extremely cautious of limbs under tension. They can spring back toward you and cause loss of control resulting in injury.

Low speed jet L

Turn the low speed jet L clockwise until it stops. If the engine accelerates poorly or idles unevenly, turn the low speed jet L anticlockwise until good acceleration and idling are achieved.
Fine adjustment of the idling speed T
Adjust the idle speed with the T-screw. If it is necessary to re-adjust, turn the T-screw clockwise while the engine is running, until the chain starts to rotate. Then turn counterclockwise until the chain stops. A correctly adjusted idle speed setting occurs when the engine runs smoothly in every position. It should also be good margin to the rpm when the chain starts to rotate.
WARNING! Contact your servicing dealer, if the idle speed setting cannot be adjusted so that the chain stops at idle. Do not use the chain saw until it has been properly adjusted or repaired.

High speed jet H

At the factory the engine is adjusted at sea level. When working at a high altitude or in different weather conditions, temperatures and atmospheric humidity, it may be necessary to make minor adjustments to the high speed jet.

English 31

CAUTION! If the high speed jet is screwed in too far, it may damage the piston/cylinder. When test run at the factory, the high speed jet is set so that the engine satises the applicable legal requirements at the same time as achieving maximum performance. The carburetors high speed jet is then locked using a limiter cap in the fully screwed out position. The limiter cap limits the potential to adjust the high speed jet to at most half a turn. To adjust the carburetor correctly you should contact a mechanic with access to a rev counter. CAUTION! As the spark is cut off, the rev counter does not show speeds higher than 13600 rpm. Move the front hand guard forwards and back to make sure it moves freely and that it is securely anchored to the clutch cover. Checking the front hand guard
Make sure the front hand guard is not damaged and that there are no visible defects such as cracks.
Correctly adjusted carburetor
When the carburetor is correctly adjusted the machine accelerates without hesitation and the machine 4-cycles a little at max. speed. It is also important that the chain does not rotate at idle. If the L-jet is set too lean it may cause starting difculties and poor acceleration. If the Hjet is set too lean the machine will have less power, poor acceleration and could suffer damage to the engine.

Check that the vibration damping elements are not damaged.
Clean the spark plug. Check that the electrode gap is 0.020 inch (0.5 mm).
Lubricate the clutch drum bearing.
Clean the outside of the carburetor.
File off any burrs from the edges of the bar.
Check fuel hose for cracks or other damage. Change if necessary.
Clean or replace the spark arrestor screen on the mufer.
Empty the fuel tank and clean the inside.
Clean the carburetor compartment.
Empty the oil tank and clean the inside.
Clean the air lter. Replace if necessary.
Check all cables and connections.

Recommended original and replacement bar and chain combinations
Following is a list of recommended cutting equipment for the Husqvarna chain saw model 455 Rancher, 455e Rancher and 460 Rancher. The combinations of power head, bar and chain have been tested and found to be in accordance with the kickback requirements of ANSI B175.12000. The guide bar nose radius is determined by either the maximum number of teeth in the nose sprocket or the corresponding maximum nose radius of a solid bar. The following list is the chain saw manufacturers recommendations. There may be other combinations available, which will also achieve kickback reduction. As we are listing the maximum guide bar nose radius, you may use a guide bar with smaller nose radius than in our list. For guide bars of the same length, all sprocket-nose guide bars of the same pitch and having the same number of sprocket teeth may be considered to have equivalent kickback energy. A hard nose bar having the same length and nose radius as a sprocket-nose bar may be considered to have equivalent or less kickback energy than the sprocket-nose bar. Low kickback saw chain is a chain which has only met the kickback performance requirements of ANSI B 175.1 safety requirements for gasoline powered chain saws when tested on the representative sample of chain saws below 3.8 cu. in. specied in ANSI 175.1. We recommend that you as a replacement use the listed chains or "Low kickback saw chains" which are available at your dealer. Saw chains Husqvarna H81 and H80 are both examples of listed Low kickback sawchains.
