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 water-powered 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. Thank you for using a Husqvarna product.

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 to 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.

Vibration damping system

Your machine is equipped with a vibration damping system that is designed to reduce vibration and make operation easier.
The mufer is designed to keep noise levels to a minimum and to direct exhaust fumes away from the user. WARNING! The exhaust fumes from the engine are hot and may contain sparks which can start a re. Never start the machine indoors or near combustible material!
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 chain saw, including the cutting equipment, is insulated from the handles by vibration damping units.
In areas with a hot, dry climate there is a high risk of res. These areas are sometimes subject to government rules requiring among other things the mufer must be equipped with an approved type of spark arrestor mesh.
Cutting hardwoods (most broadleaf trees) creates more vibration than cutting softwoods (most conifers). Cutting with cutting equipment that is blunt or faulty (wrong type or badly sharpened) will increase the vibration level.
CAUTION! The mufer gets very hot during and after use. This also applies during idling. Be aware of the re hazard, especially when working near ammable substances and/ or vapours.
WARNING! Overexposure to vibration can lead to circulatory damage or nerve damage in people who have impaired circulation. Contact your doctor if you experience symptoms of overexposure to vibration. Such symptoms include numbness, loss of feeling, tingling, pricking, pain, loss of strength, changes in skin colour or condition. These symptoms normally appear in the ngers, hands or wrists. These symptoms may be increased in cold temperatures.

WARNING! Never use a saw without a mufer, or with a damaged mufer. A damaged mufer may substantially increase the noise level and the re hazard. Keep re ghting equipment handy. If a spark arrestor screen is required in your area, never use the saw without or with a broken spark arrestor screen.

Cutting equipment

This section describes how to choose and maintain your cutting equipment in order to: Reduce the risk of kickback. Reduce the risk of the saw chain breaking or jumping off the bar. Obtain optimal cutting performance. Extend the life of cutting equipment. Avoid increasing vibration levels.

Stop switch

Use the stop switch to switch off the engine.

10 English

General rules
Only use cutting equipment recommended by us! See instructions under the heading Technical data.
A chain is made up of a number of links, which are available in standard and low-kickback versions. IMPORTANT! No saw chain design eliminates the danger of kickback.
Keep the chains cutting teeth properly sharpened! Follow our instructions and use the recommended le gauge. A damaged or badly sharpened chain increases the risk of accidents.
WARNING! Any contact with a rotating saw chain can cause extremely serious injuries.
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.
Maintain the correct depth gauge setting! Follow our instructions and use the recommended depth gauge clearance. Too large a clearance increases the risk of kickback.

Length (inches/cm)

Keep the chain properly tensioned! If the chain is slack it is more likely to jump off and lead to increased wear on the bar, chain and drive sprocket.
Number of teeth on bar tip sprocket (T).
Keep cutting equipment well lubricated and properly maintained! A poorly lubricated chain is more likely to break and lead to increased wear on the bar, chain and drive sprocket.
Chain pitch (inches). The spacing between the drive links of the chain must match the spacing of the teeth on the bar tip sprocket and drive sprocket.

12 English
File all the teeth to the same length. When the length of the cutting teeth is reduced to 4 mm (0.16") the chain is worn out and should be replaced.

Tensioning the chain

General advice on adjusting depth gauge setting
When you sharpen the cutting tooth (A) the depth gauge setting (C) will decrease. To maintain optimal cutting performance the depth gauge (B) has to be led down to achieve the recommended depth gauge setting. See instructions under the heading Technical data to nd the correct depth gauge setting for your particular chain.
WARNING! A slack chain may jump off the bar and cause serious or even fatal injury.
The more you use a chain the longer it becomes. It is therefore important to adjust the chain regularly to take up the slack. Check the chain tension every time you refuel. NOTE! A new chain has a running-in period during which you should check the tension more frequently. Tension the chain as tightly as possible, but not so tight that you cannot pull it round freely by hand.
WARNING! The risk of kickback is increased if the depth gauge setting is too large!

455 Rancher, 460

Adjustment of depth gauge setting
The cutting teeth should be newly sharpened before adjusting the depth gauge setting. We recommend that you adjust the depth gauge setting every third time you sharpen the cutting teeth. NOTE! This recommendation assumes that the length of the cutting teeth is not reduced excessively. You will need a at le and a depth gauge tool. We recommend that you use our depth gauge tool to acheive the correct depth gauge setting and bevel for the depth gauge. Loosen the bar nuts that hold the clutch cover/chain brake. Use the combination spanner. Then tighten the bar nuts by hand as tight as you can.
Raise the tip of the bar and stretch the chain by tightening the chain tensioning screw using the combination spanner. Tighten the chain until it does not sag from the underside of the bar.
Place the depth gauge tool over the chain. Detailed information regarding the use of the depth gauge tool, will be found on the package for the depth gauge tool. Use the at le to le off the tip of the depth gauge that protrudes through the depth gauge tool. The depth gauge setting is correct when you no longer feel resistance as you draw the le along the depth gauge tool.
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.

Needle bearing lubrication
If the chain lubrication is not working: Check that the oil channel in the bar is not obstructed. Clean if necessary. 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. See instructions under the heading Maintenance, Needle bearing lubrication.
Checking wear on cutting equipment
Check that the groove in the edge of the bar is clean. Clean if necessary. Check the chain daily for:
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.
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 4 mm (0,16 inch) the chain must be replaced. If the chain lubrication system is still not working after carrying out the above checks and associated measures you should contact your servicing dealer.
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.
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.
To prolong the life of the bar you should turn it over daily.
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.

ASSEMBLY
Fitting the bar and chain
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.
WARNING! Always wear gloves, when working with the chain, in order to protect your hands from injury.
Check that the chain brake is in disengaged position by moving the front hand guard towards the front handle.
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.
Remove the bar nuts and remove the clutch cover (chain brake). Take off the transportation ring (A). Check that the chain brake is in disengaged position by moving the front hand guard towards the front handle.
Remove the knob and remove the clutch cover (chain brake). Take off the transportation ring. Fit the bar over the bar bolts. Place the bar in its rearmost position. Place the chain over the drive sprocket locate it in the groove on the bar. Begin on the top edge of the bar.
Make sure that the edges of the cutting links are facing forward on the top edge of the bar. Fit the clutch cover and locate the chain adjuster pin in the hole in the bar. Check that the drive links of the chain t correctly over the drive sprocket and that the chain is correctly located in the groove in the bar. Tighten the bar nuts nger tight. 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.
Fit the bar over the bar bolts. Place the bar in its rearmost position. Place the chain over the drive sprocket locate it in the groove on the bar. Begin on the top edge of the bar.
Make sure that the edges of the cutting links are facing forward on the top edge of the bar. Fit the clutch cover and locate the chain adjuster pin in the hole in the bar. Check that the drive links of the chain t correctly over the drive sprocket and that the chain is correctly located in the groove in the bar. Tighten the bar nuts nger tight.

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 clutch by turning the knob clockwise.

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.

Long-term storage

Empty the fuel/oil tanks in a well ventilated area. Store the fuel in approved cans in a safe place. Fit the bar guard. Clean the machine. See instructions under the heading Maintenance schedule.

STARTING AND STOPPING

Starting and stopping

Warm engine
Use the same procedure as for starting a cold engine but without setting the choke control in the choke position. The correct choke/start throttle setting is obtained by moving the choke control to the choke position and then pushing it in again.
WARNING! Note the following before starting: The chain brake must be engaged when the chain saw is started to reduce the chance of contact with the moving chain during starting. Never start a chain saw unless the bar, chain and all covers are tted correctly. Otherwise the clutch can come loose and cause personal injuries. Place the machine on rm ground. Make sure you have a secure footing and that the chain cannot touch anything. Keep people and animals well away from the working area.

Starting

Cold engine
Starting: The chain brake should be activated when starting the chain saw. Activate the chain brake by pushing the front hand guard forwards.
Grip the front handle with your left hand. Hold the chain saw on the ground by placing your right foot through the rear handle. 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. Never wrap the starter cord around your hand

5 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. Lack of concentration can lead to kickback if the kickback zone of the bar accidentally touches a branch, nearby tree or some other object.
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.
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.
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 lefthanded. This grip minimizes the effect of kickback and lets you keep the chain saw under control. Do not let go of the handles! 4 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.
Always use a fast cutting speed, i.e. full throttle.

24 English

7 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 user. If the saw chain is jamming, the saw may be pushed back at you.

Cutting with a pushing chain increases the risk of kickback. See instructions under the heading How to avoid kickback.

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

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.
The log is supported at one end. There is a high risk that it will split.
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.
Finish by cutting from below so that the two cuts meet.
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.

26 English

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! 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.

Safe distance

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.

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.
Continue to cut deeper until tree/limb bends and tension is released.
Cut tree/limb from outside the bend, after tension has been released.

How to avoid kickback

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.
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.
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.

30 English

MAINTENANCE
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.

Some mufers are equipped with a special spark arrestor mesh. If your machine has this type of mufer, you should clean the mesh at least once a week. This is best done with a wire brush. A blocked mesh will cause the engine to overheat and may lead to serious damage.
Pull out the cord approx. 30 cm (12 inches) and hook it into the notch in the rim of the pulley. Release the recoil spring by letting the pulley rotate slowly backwards.

34 English

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.

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 an additional 1/ 2 turn when the starter cord is pulled all the way out.

Air lter

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.
Changing a broken recoil spring
Lift off the pulley. See instructions under heading Changing a broken or worn starter cord. Remove the recoil spring from inside the pulley by tapping the pulley lightly with its inside face downwards against a work bench or the like. If the spring pops out during tting, wind it up again, working from the outside in towards centre. Lubricate the recoil spring with light oil. Fit the pulley and tension the recoil spring. 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 lters according to working conditions, weather, season, etc. Contact your dealer for advice.
Spark plug Needle bearing lubrication
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.

Recommended original and replacement bar and chain combinations
Following is a list of recommended cutting equipment for the Husqvarna chain saw model 455 Rancher. The combinations of power head, bar and chain have been tested and found to be in accordance with the kickback and vibration requirements of ANSI B 175.12000. 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.

With a basic understanding of kickback, you can reduce or eliminate the element of surprise. Sudden surprise contributes to accidents. Keep a good rm grip on the saw with both hands, the right hand on the rear handle, and the left hand on the front handle, when the engine is running. Use a rm grip with thumbs and ngers encircling the chain saw handles. A rm grip will help you reduce kickback and maintain control of the saw. Dont let go. Make sure that the area in which you are cutting is free from obstacles. Do not let the nose of the guide bar contact a log, branch, or any other obstacle which could be hit while you are operating the saw. Cut at high engine speeds. Do not overreach or cut above shoulder height. Follow manufacturers sharpening and maintenance instructions for the saw chain. Only use replacement bars and chains specied by the manufacturer or the equivalent.

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.

Stop switch

Use the stop switch to switch off the engine.

General rules

Only use cutting equipment recommended by us! See instructions under the heading Technical data.
The mufer is designed to keep noise levels to a minimum and to direct exhaust fumes away from the user.
Keep the chains cutting teeth properly sharpened! Follow our instructions and use the recommended le gauge. A damaged or badly sharpened chain increases the risk of accidents.
WARNING! The exhaust fumes from the engine are hot and may contain sparks which can start a re. Never start the machine indoors or near combustible material!
In areas with a hot, dry climate there is a high risk of res. These areas are sometimes subject to government rules
Maintain the correct depth gauge setting! Follow our instructions and use the recommended depth gauge clearance. Too large a clearance increases the risk of kickback.

10 English

Keep the chain properly tensioned! If the chain is slack it is more likely to jump off and lead to increased wear on the bar, chain and drive sprocket. Bar Length (inches/cm)
Keep cutting equipment well lubricated and properly maintained! A poorly lubricated chain is more likely to break and lead to increased wear on the bar, chain and drive sprocket.
Number of teeth on bar tip sprocket (T).
Chain pitch (inches). The spacing between the drive links of the chain must match the spacing of the teeth on the bar tip sprocket and drive sprocket.
Cutting equipment designed to reduce kickback
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.
Number of drive links. The number of drive links is determined by the length of the bar, the chain pitch and the number of teeth on the bar tip sprocket.
Bar groove width (inches/mm). The groove in the bar must match the width of the chain drive links.
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. IMPORTANT! No saw chain design eliminates the danger of kickback. WARNING! Any contact with a rotating saw chain can cause extremely serious injuries. Chain Chain pitch (inches) Chain oil hole and hole for chain tensioner. The bar must be matched to the chain saw design.

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. 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) Chain drive sprocket
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 If the chain lubrication is not working: Check that the oil channel in the bar is not obstructed. Clean if necessary. Both versions of sprockets have a needle bearing on the drive shaft, which has to be greased regularly (once a week). CAUTION! Use a high-quality bearing grease or engine oil. See instructions under the heading Maintenance, Needle bearing lubrication. Checking wear on cutting equipment Check that the groove in the edge of the bar is clean. Clean if necessary. Check the chain daily for:
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.
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 4 mm the chain must be replaced.
If the chain lubrication system is still not working after carrying out the above checks and associated measures you should contact your service agent.

English 15

Bar To prolong the life of the bar you should turn it over daily.
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.
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.

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.

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.
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. 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.
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.

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 on the pull stroke. Cutting from below = Cutting on the push stroke. Cutting on the push stroke increases the risk of kickback. See instructions under the heading How to avoid kickback. 82-26 Rev.1 2009-03-02

English 25

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.
Finish by cutting from below so that the two cuts meet. 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.

26 English

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 that you feel unsure of! Safe distance 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. 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.

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! 82-26 Rev.1 2009-03-02 English 29
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. Limbing
Cut tree/limb from outside the bend, after tension has been released.

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.
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.

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.
Keep the trunk between you and the chain saw as you move along the trunk. Cutting the trunk into logs 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. See instructions under the heading Basic cutting technique.

Conditions

Before any adjustments are made the air lter should be clean and the cylinder cover tted. Adjusting the carburettor 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 idle 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 anticlockwise until the chain stops. When the idle speed is correctly adjusted the engine should run smoothly in every position and the engine speed should be safely below the speed at which the chain starts to rotate.
WARNING! Contact your servicing dealer, if the idle speed setting cannot be adjusted so that the chain stops. Do not use the chain saw until it has been properly adjusted or repaired.

English 31

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 carburettors 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 carburettor 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 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.
Correctly adjusted carburettor

Special measures are therefore often required:
Temperature 0C or colder:
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 carburettor space preventing icing of the air lter, etc.
Temperature -5C or colder:
For running the machine in cold weather or powder snow, a special cover is available, which is mounted on the starter housing. This reduces the intake of cold air and prevents large amounts of snow from being sucked in.
CAUTION! If the special winterising kit has been tted or any measures have been taken to increase the temperature these changes must be reversed before the machine is used in normal temperature conditions.

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 0.6 mm (0,024 inch) 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.
