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.
WARNING! Never allow children to use or be in the vicinity of the machine. As the machine is equipped with a springloaded stop switch and can be started by low speed and force on the starter handle, even small children under some circumstances can produce the force necessary to start the machine. This can mean a risk of serious personal injury. Therefore remove the spark plug cap when the machine is not under close supervision.

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.

The saw chain oil tank and the fuel tank are designed so that the fuel runs out before the saw chain oil. However, this safety feature requires that you use the right sort of chain oil (if the oil is too thin it will run out before the fuel), and that you adjust the carburetor as recommended (a lean mixture may mean that the fuel lasts longer than the oil) and that you also use the recommended cutting equipment (a bar that is too long will use more chain oil).
Check that the bar tip sprocket turns freely and that the lubricating hole in the tip sprocket is not blocked. Clean and lubricate if necessary.
If the chain lubrication system is still not working after carrying out the above checks and associated measures you should contact your servicing dealer.

14 English

Chain drive sprocket Bar
The clutch drum is tted with one of the following drive sprockets: A Spur sprocket (the chain sprocket is welded on the drum) B Rim sprocket (replaceable)
Check regularly: Whether there are burrs on the edges of the bar. Remove these with a le if necessary.
Whether the groove in the bar has become badly worn. Replace the bar if necessary.
Regularly check the degree of wear on the drive sprocket. Replace if wear is excessive. Replace the drive sprocket whenever you replace the chain. Needle bearing lubrication Whether the tip of the bar is uneven or badly worn. If a hollow forms on the underside of the bar tip this is due to running with a slack chain.
Both versions of sprockets have a needle bearing on the drive shaft, which has to be greased regularly (once a week). CAUTION! Use only high quality bearing grease or engine oil.
To prolong the life of the bar you should turn it over daily.
Checking wear on cutting equipment
WARNING! Most chain saw accidents happen when the chain touches the operator. Wear personal protective equipment. See instructions under the heading Personal protective equipment. Do not tackle any job that you feel you are not adequately trained for. See instructions under the headings Personal protective equipment, How to avoid kickback, Cutting equipment and General working instructions. Avoid situations where there is a risk of kickback. See instructions under the heading Machines safety equipment. Use the recommended protective equipment and check its condition. See instructions under the heading General working instructions. Check that all the chain saw safety features are working. See instructions under the headings General working instructions and General safety precautions.
Check the chain daily for:
Visible cracks in rivets and links. Whether the chain is stiff. Whether rivets and links are badly worn.
Replace the saw chain if it exhibits any of the points above. We recommend you compare the existing chain with a new chain to decide how badly the existing chain is worn. When the length of the cutting teeth has worn down to only 0.16 inch (4 mm) the chain must be replaced.

Gasoline

Mixing
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. Always mix the gasoline and oil in a clean container intended for fuel. Always start by lling half the amount of the gasoline to be used. Then add the entire amount of oil. Mix (shake) the fuel mixture. Add the remaining amount of gasoline. Mix (shake) the fuel mixture thoroughly before lling the machines fuel tank. Do not mix more than one months supply of fuel at a time. If the machine is not used for some time the fuel tank should be emptied and cleaned.
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.
We recommend the use of special oil (chain oil) with good adhesion characteristics.

Two-stroke oil

For best results and performance use HUSQVARNA two-stroke engine oil, which is specially formulated for our air-cooled two stroke-engines. Never use two-stroke oil intended for water-cooled engines, sometimes referred to as outboard oil (rated TCW). Never use oil intended for four-stroke engines. 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. English 17

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. 3 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. 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.

Felling

WARNING! Unless you have special training we advise you not to fell trees with a diameter larger than the bar length of your saw!
Felling is done using three cuts. First you make the directional cuts, which consist of the top cut and the bottom cut, then you nish with the felling cut. By placing these cuts correctly you can control the felling direction very accurately. Directional cuts To make the directional cut you begin with the top cut. Aim using to the saws felling direction mark (1) toward a goal further forward in the terrain, where you would like the tree to fall (2). Stand on the right-hand side of the tree, behind the saw, and cut with a pull stroke.
IMPORTANT! During critical felling operations, hearing protectors should be lifted immediately when sawing is completed so that sounds and warning signals can be heard.

English 25

Next make the bottom cut so that it nishes exactly at the end of the top cut. 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 directional cuts should run 1/4 of the diameter through the trunk and the angle between the top cut and bottom cut should be 45. The line where the two cuts meet is called the directional cut line. This line should be perfectly horizontal and at right angles (90) to the chosen felling direction.
When the felling cut and directional cut are complete the tree should start to fall by itself or with the aid of a felling wedge or breaking bar.
Felling cut The felling cut is made from the opposite side of the tree and it must be perfectly horizontal. Stand on the left side of the tree and cut on the pull stroke. Make the felling cut about 1.5-2 inches (3-5 cm) above the bottom directional cut.
We recommend that you use a bar that is longer than the diameter of the tree, so that you can make the felling cut and directional cuts with single cutting strokes. See instructions under the heading Technical data section to nd out which lengths of bar are recommended for your saw.
There are methods for felling trees with a diameter larger than the bar length. However these methods involve a much greater risk that the kickback zone of the bar will come into contact with the tree.

Finish the felling cut parallel with the directional cut line so that the distance between them is at least 1/10 of the trunk diameter. The uncut section of the trunk is called the felling hinge. The felling hinge controls the direction that the tree falls in.

26 English

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. 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. necessary to reduce the tension and make the tree or branch break at the point of maximum tension.
Continue to cut deeper until tree/limb bends and tension is released. The safest method is to use a winch. Tractor-mounted Cut tree/limb from outside the bend, after tension has been released. Portable

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.
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 Make one or more cuts at or near the point of maximum tension. Make as many cuts of sufcient depth as

English 27

was being used when the kickback zone of the bar touched the object.
Kickback only occurs if the kickback zone of the bar touches an object.

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.

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.
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.

MAINTENANCE

General

The user must only carry out the maintenance and service work described in this manual. IMPORTANT! Any maintenance other than that described in this manual must be carried out by your servicing dealer (retailer). 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.
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.
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.

1/2 1/2

Conditions
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

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.

English 29

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. 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. CAUTION! There is an integrated speed governor in the ignition system that limits the maximum speed to 13600 rpm. The maximum speed will not exceed 13600 rpm when the high speed jet is adjusted (screwed in). When the speed governor is activated, you will get the same sound experience as when the chain saw 4-cycles. 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.
Checking, maintaining and servicing chain saw safety equipment
Note! All servicing and repair work on the machine requires special training. This is especially true of the machines safety equipment. If your machine fails any of the checks described below we recommend you to contact our servicing dealer.

Checking brake band wear

Brush off any wood dust, resin and dirt from the chain brake and clutch drum. Dirt and wear can impair operation of the brake.
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 H-jet is set too lean the machine will have less power, poor acceleration and could suffer damage to the engine. 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.
Move the front hand guard forwards and back to make sure it moves freely and that it is securely anchored to the clutch cover.

30 English

Checking the inertia brake release go of the front handle. The chain should stop immediately.
With the engine turned off, hold the chain saw over a stump or other rm object. Let go of the front handle so that the bar drops towards the stump as the chain saw rotates around the rear handle.
Make sure the throttle control is locked at the idle setting when the throttle lockout is released.
When the bar hits the stump the brake should be applied. Press the throttle lockout and make sure it returns to its original position when you release it.
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. Check that the throttle control and throttle lockout move freely and that the return springs work properly.
Grasp the chain saw rmly, wrapping your ngers and thumbs around the handles. 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.
Apply full throttle and activate the chain brake by tilting your left wrist forward onto the front hand guard. Do not let

English 31

Chain catcher Stop switch
Check that the chain catcher is not damaged and is rmly attached to the body of the chain saw.
Start the engine and make sure the engine stops when you move the stop switch to the stop setting.
Check that the right hand guard is not damaged and that there are no visible defects, such as cracks.
Never use a machine that has a faulty mufer.
Regularly check that the mufer is securely attached to the machine.
Regularly check the vibration damping units for cracks or deformation.
Make sure the vibration damping units are securely attached to the engine unit and handle unit.
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

32 English

use a mufer if the spark arrestor screen is missing or defective. recoil spring by letting the pulley rotate slowly backwards.
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. A mufer equipped with a catalytic converter signicantly reduces the amount of hydrocarbons (HC), nitrogen oxides (NO) and aldehydes in the exhaust fumes. Carbon monoxide (CO), which is poisonous and odorless, is not however reduced! Consequently, never work in an enclosed or badly ventilated area. Good air circulation should always prevail when working in snowy hollows, ravines or in conned conditions.
Undo the screw in the centre of the pulley and remove the pulley. Insert and fasten a new starter cord to the pulley. Wind approx. 3 turns of the starter cord onto the pulley. Connect the pulley to the recoil spring so that the end of the spring engages in the pulley. Fit the screw in the center of the pulley. Insert the starter cord through the hole in the starter housing and the starter handle. Make a secure knot in the end of the starter cord.

Starter

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.
Tensioning the recoil spring
Hook the starter cord in the notch in the pulley and turn the starter pulley about 2 turns clockwise. Note! Check that the pulley can be turned an additional 1/2 turn when the starter cord is pulled all the way out.

English 37

Maintenance schedule
The following is a list of the maintenance that must be performed on the machine. Most of the items are described in the Maintenance section. Daily maintenance Weekly maintenance On chain saws without a catalytic converter, check the cooling system weekly. Check the starter, starter cord and return spring. Monthly maintenance Check the brake band on the chain brake for wear. Replace when less than 0.024 inch (0.6 mm) remains at the most worn point. Check the clutch centre, clutch drum and clutch spring for wear.
Clean the outside of the machine.
Check that the components of the throttle control work safely. (Throttle lockout and throttle control.) Clean the chain brake and check that it operates safely. Make sure that the chain catcher is undamaged, and replace it if necessary. The bar should be turned daily for more even wear. Check the lubrication hole in the bar, to be sure it is not clogged. Clean the bar groove. If the bar has a sprocket tip, this should be lubricated. Check that the bar and chain are getting sufcient oil. Check the saw chain with regard to visible cracks in the rivets and links, whether the saw chain is stiff or whether the rivets and links are abnormally worn. Replace if necessary. Sharpen the chain and check its tension and condition. Check the drive sprocket for excessive wear and replace if necessary. Clean the starter units air intake. Check that nuts and screws are tight. Check that the stop switch works correctly. Check that there are no fuel leaks from the engine, tank or fuel lines. On chain saws with a catalytic converter, check the cooling system daily.
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.

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 Husqvarna River, for production of muskets. The location was logical, since water power was harnessed from the Huskvarna River to create the waterpowered plant. During the more than 300 years of beeing, 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. The business concept is to develop, manufacture and market motor driven products for forestry and gardening as well as for building and construction industry. Husqvarnas aim is also to be in the front edge according to ergonomics, usability, security and environmental protection. That is the reason why we have developed many different features to provide our products within these areas. We are convinced that you will appreciate with great satisfaction the quality and performance of our product for a very long time to come. The purchase of one of our products 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 authorised dealers, ask for the address of your nearest service workshop. 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.

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.
WARNING! Never allow children to use or be in the vicinity of the machine. As the machine is equipped with a springloaded stop switch and can be started by low speed and force on the starter handle, even small children under some circumstances can produce the force necessary to start the machine. This can mean a risk of serious personal injury. Therefore remove the spark plug cap when the machine is not under close supervision.

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.

Work is constantly in progress to improve the design and technology - improvements that increase your safety and efciency. Visit your dealer regularly to see whether you can benet from new features that have been introduced.
Personal protective equipment
WARNING! Most chain saw accidents happen when the chain touches the operator. You must use approved personal protective equipment whenever you use the machine. Personal protective equipment cannot eliminate the risk of injury but it will reduce the degree of injury if an accident does happen. Ask your dealer for help in choosing the right equipment.
WARNING! Never use a machine with defective safety components. Safety equipment must be inspected and maintained. See instructions under the heading Checking, maintaining and servicing chain saw safety equipment. If your machine does not pass all the checks, take the saw to a servicing dealer for repair.
Chain brake and front hand guard
Your chain saw is equipped with a chain brake that is designed to stop the chain if you get a kickback. The chain brake reduces the risk of accidents, but only you can prevent them.
Take care when using your saw and make sure the kickback zone of the bar never touches any object.
Approved protective helmet Hearing protection Protective goggles or a visor Gloves with saw protection Trousers with saw protection English 7
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.

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. Chain oil hole and hole for chain tensioner. The bar must be matched to the chain saw design.
The only way to avoid kickback is to make sure that the kickback zone of the bar never touches anything. By using cutting equipment with built-in kickback reduction and keeping the chain sharp and wellmaintained you can reduce the effects of kickback. Bar The smaller the tip radius the lower the chance of kickback. Chain A chain is made up of a number of links, which are available in standard and low-kickback versions.
Chain Chain pitch (inches)
IMPORTANT! No saw chain design eliminates the danger of kickback.
Drive link width (mm/inches)
WARNING! Any contact with a rotating saw chain can cause extremely serious injuries.

Number of drive links.

Some terms that describe the bar and chain To maintain the safety features of the cutting equipment, you should replace a worn or damaged bar or chain with a bar and chain combinations recommended by Husqvarna. See instructions under the heading Technical Data for a list of replacement bar and chain combinations we recommend. English 11
Sharpening your chain and adjusting depth gauge setting
General information on sharpening cutting teeth Never use a blunt chain. When the chain is blunt you have to exert more pressure to force the bar through the wood and the chips will be very small. If the chain is very blunt it will produce wood powder and no chips or shavings. A sharp chain eats its way through the wood and produces long, thick chips or shavings. To sharpen cutting teeth you will need a round le and a le gauge. See instructions under the heading Technical data for information on the size of le and gauge that are recommended for the chain tted to your chain saw. The cutting part of the chain is called the cutter and consists of a cutting tooth (A) and the depth gauge (B). The cutters cutting depth is determined by the difference in height between the two (depth gauge setting). Check that the chain is correctly tensioned. A slack chain will move sideways, making it more difcult to sharpen correctly. See instructions under the heading Technical data for information about sharpening your chain.

Use the combination spanner to tighten the bar nuts while lifting the tip of the bar at the same time. Check that you can pull the chain round freely by hand and that it does not sag from the underside of the bar.
The position of the chain tensioning screw on our chain saws varies from model to model. See instructions under the heading What is what? to nd out where it is on your model.

English 13

Lubricating cutting equipment
Checking chain lubrication Check the chain lubrication each time you refuel. See instructions under the heading Lubricating the bar tip sprocket. Aim the tip of the bar at a light coloured surface about 20 cm (8 inches) away. After 1 minute running at 3/4 throttle you should see a distinct line of oil on the light surface. WARNING! Poor lubrication of cutting equipment may cause the chain to snap, which could lead to serious, even fatal injuries.

Chain oil

Chain oil must demonstrate good adhesion to the chain and also maintain its ow characteristics regardless of whether it is warm summer or cold winter weather. As a chain saw manufacturer we have developed an optimal chain oil which, with its vegetable oil base, is also biodegradable. We recommend the use of our own oil for both maximum chain life and to minimise environmental damage. If our own chain oil is not available, standard chain oil is recommended. Never use waste oil! Using waste oil can be dangerous to you and damage the machine and environment. IMPORTANT! When using vegetable based saw chain oil, dismantle and clean the groove in the bar and saw chain before long-term storage. Otherwise there is a risk of the saw chain oil oxidizing, which will result in the saw chain becoming stiff and the bar tip sprocket jamming. Filling with chain oil All our chain saws have an automatic chain lubrication system. On some models the oil ow is also adjustable. Check that the groove in the edge of the bar is clean. Clean if necessary. If the chain lubrication is not working: Check that the oil channel in the bar is not obstructed. Clean if necessary.
The saw chain oil tank and the fuel tank are designed so that the fuel runs out before the saw chain oil. However, this safety feature requires that you use the right sort of chain oil (if the oil is too thin it will run out before the fuel), and that you adjust the carburetor as recommended (a lean mixture may mean that the fuel lasts longer than the oil) and that you also use the recommended cutting equipment (a bar that is too long will use more chain oil).
Check that the bar tip sprocket turns freely and that the lubricating hole in the tip sprocket is not blocked. Clean and lubricate if necessary.
If the chain lubrication system is still not working after carrying out the above checks and associated measures you should contact your service agent.

WARNING! Long term inhalation of the engines exhaust fumes, chain oil mist and dust from sawdust can represent a health risk.
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.

Stopping

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.
The engine is stopped by pushing the stop switch to the stop position.
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,

20 English

WORKING TECHNIQUES

Before use:

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. 3 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.
10 Check the chain tension.
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 feel unsure of! 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. 5 Take great care when cutting a tree that is in tension. A tree that is in 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. 4 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.

Basic safety rules

1 Look around you: To ensure that people, animals or other things cannot affect your control of the machine.

English 21

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.
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. Fit a guard to the bar before transporting the chain saw or carrying it for any distance.
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.
Never use the chain saw above shoulder height and try not to cut with the tip of the bar. Never use the chain saw one-handed!
1 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 minimises the effect of kickback and lets you keep the chain saw under control. Do not let go of the handles!
You must have a steady stance in order to have full control over the chain saw. Never work standing on a ladder, in a tree or where you do not have rm ground to stand on.
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 on the push stroke. The chain tries to push the chain saw back towards the user. If

Felling cut The felling cut is made from the opposite side of the tree and it must be perfectly horizontal. Stand on the left side of the tree and cut on the pull stroke. Make the felling cut about 3-5 cm (1.5-2 inches) above the bottom directional cut. We recommend that you use a bar that is longer than the diameter of the tree, so that you can make the felling cut and directional cuts with single cutting strokes. See instructions under the heading Technical data section to nd out which lengths of bar are recommended for your saw.
Set the spike bumper (if one is tted) just behind the felling hinge. Use full throttle and advance the chain/bar slowly into the tree. Make sure the tree does not start to move in the opposite direction to your intended felling direction. Drive a wedge or breaking bar into the cut as soon as it is deep enough.
There are methods for felling trees with a diameter larger than the bar length. However these methods involve a much greater risk that the kickback zone of the bar will come into contact with the tree.
Finish the felling cut parallel with the directional cut line so that the distance between them is at least 1/10 of the trunk diameter. The uncut section of the trunk is called the felling hinge. 26 English
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. 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. necessary to reduce the tension and make the tree or branch break at the point of maximum tension.
Continue to cut deeper until tree/limb bends and tension is released. The safest method is to use a winch. Tractor-mounted Cut tree/limb from outside the bend, after tension has been released. Portable

How to avoid kickback

Checking, maintaining and servicing chain saw safety equipment
Note! All service and repair work on the machine demands special training. This is especially true of the machines safety equipment. If your machine fails any of the checks described below we recommend that you take it to your service workshop. Checking the inertia brake release
Place the chain saw, with the engine switched off, on a stump or other stable surface. Release the front handle and let the saw fall by its own weight, rotating around the rear handle towards the stump.

Checking brake band wear

Brush off any wood dust, resin and dirt from the chain brake and clutch drum. Dirt and wear can impair operation of the brake.
When the bar hits the stump the brake should be applied.
Checking the brake trigger Regularly check that the brake band is at least 0.6 mm thick at its thinnest point. Checking the front hand guard 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.
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. Move the front hand guard forwards and back to make sure it moves freely and that it is securely anchored to the clutch cover.
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.

32 English

Throttle lockout Chain catcher
Make sure the throttle control is locked at the idle setting when the throttle lockout is released.
Check that the chain catcher is not damaged and is rmly attached to the body of the chain saw.
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.
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 carburettor idle adjustment.
Regularly check the vibration damping units for cracks or deformation.

Undo the screw in the centre of the pulley and remove the pulley. Insert and fasten a new starter cord to the pulley. Wind approx. 3 turns of the starter cord onto the pulley. Connect the pulley to the recoil spring so that the end of the spring engages in the pulley. Fit the screw in the centre of the pulley. Insert the starter cord through the hole in the starter housing and the starter handle. Make a secure knot in the end of the starter cord.

Fitting the starter

To t the starter, rst pull out the starter cord and place the starter in position against the crankcase. Then slowly release the starter cord so that the pulley engages with the pawls. Fit and tighten the screws that hold the starter.
Tensioning the recoil spring
Hook the starter cord in the notch in the pulley and turn the starter pulley about 2 turns clockwise. Note! Check that the pulley can be turned at least a further 1/2 turn when the starter cord is pulled all the way out.

English 35

Air lter Spark plug
The air lter must be regularly cleaned to remove dust and dirt in order to avoid: Carburettor malfunctions Starting problems Loss of engine power Unnecessary wear to engine parts. Excessive fuel consumption. Remove the air lter after taking off the air lter cover. When retting make sure that the air lter seals tightly against the lter holder. Clean the lter by brushing or shaking it.
The spark plug condition is inuenced by: Incorrect carburettor adjustment. An incorrect fuel mixture (too much or incorrect type of oil). A dirty air lter.
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 0.5 mm. The spark plug should be replaced after about a month in operation or earlier if necessary.
The lter can be cleaned more thoroughly by washing it in water and detergent. An air lter that has been in use for a long time cannot be cleaned completely. The lter must therefore be replaced with a new one at regular intervals. A damaged air lter must always be replaced. A HUSQVARNA chain saw can be equipped with different types of air lter according to working conditions, weather, season, etc. Contact your dealer for advice.
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.

Clean the outside of the machine.
Check that the components of the throttle control work safely. (Throttle lockout and throttle control.) Clean the chain brake and check that it operates safely. Make sure that the chain catcher is undamaged, and replace it if necessary. The bar should be turned daily for more even wear. Check the lubrication hole in the bar, to be sure it is not clogged. Clean the bar groove. If the bar has a sprocket tip, this should be lubricated. Check that the bar and chain are getting sufcient oil. Check the saw chain with regard to visible cracks in the rivets and links, whether the saw chain is stiff or whether the rivets and links are abnormally worn. Replace if necessary. Sharpen the chain and check its tension and condition. Check the drive sprocket for excessive wear and replace if necessary. Clean the starter units air intake. Check that nuts and screws are tight. Check that the stop switch works correctly. Check that there are no fuel leaks from the engine, tank or fuel lines. On chain saws with a catalytic converter, check the cooling system daily.
Check that the vibration damping elements are not damaged.
Clean the spark plug. Check that the electrode gap is 0.5 mm.
Lubricate the clutch drum bearing.
Clean the outside of the carburettor.
File off any burrs from the edges of the bar.
Check the fuel lter and the fuel hose. Replace if necessary.
Clean or replace the spark arrestor mesh on the mufer.
Empty the fuel tank and clean the inside.
Clean the carburettor compartment.
Empty the oil tank and clean the inside.
Clean the air lter. Replace if necessary.
Check all cables and connections.
