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. If you will sell this machine, make sure that the buyer will get the operators manual. Thank you for using a Husqvarna product.
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 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. activated for long periods. The chain saw can become very hot.
This movement activates a spring-loaded mechanism that tightens the brake band (C) around the engine drive system (D) (clutch drum). To release the chain brake pull the front hand guard backwards, towards the front handle.
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.
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 chain brake must be engaged when the chain saw is started to prevent the saw chain from rotating. 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.
Will my inertia activated chain brake always activate during kickback in the event of a kickback?
No. First your brake must be in working order. Testing the brake is simple, see instructions under the heading Checking, maintaining and servicing chain saw safety equipment. We recommend you do before you begin each work session. Second the kickback must be strong enough to activate the chain brake. If the chain brake is too sensitive it would activate all the time which would be a nuisance.
Right hand guard
Apart from protecting your hand if the chain jumps or snaps, the right hand guard stops branches and twigs from interfering with your grip on the rear handle.
Use the stop switch to switch off the engine.
Mufer Vibration damping system
Your machine is equipped with a vibration damping system that is designed to minimize 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! 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.
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.
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 a high-quality bearing grease or engine oil. See instructions under the heading Maintenance, Needle bearing lubrication. Checking wear on cutting equipment To prolong the life of the bar you should turn it over regularly.
Check the chain daily for:
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.
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.
Fitting the bar and chain
should be tensioned until it does not sag from the underside of the bar.
WARNING! Always wear gloves, when working with the 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.
Check that the chain brake is in disengaged position by moving the front hand guard towards the front handle.
Remove the bar nuts and remove the clutch cover (chain brake). Take off the transportation ring (A).
When tting a new chain, the chain tension has to be checked frequently until the chain is run-in. Check the chain tension regularly. A correctly tensioned chain ensures good cutting performance and long life.
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
Loosen the chain tensioner wheel and remove the clutch cover (chain brake). Remove the transport guard.
Fitting a spike bumper
To t a spike bumper contact your service agent.
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. Tension the chain by turning the wheel down (+). The chain should be tensioned until it does not sag from the underside of the bar.
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 knob by turning the knob clockwise.
Note! The machine is equipped with a two-stroke engine and must always be run using a mixture of petrol and twostroke oil. It is important to accurately measure the amount of oil to be mixed to ensure that the correct mixture is obtained. When mixing small amounts of fuel, even small inaccuracies can drastically affect the ratio of the mixture. Mixing ratio 1:50 (2%) with HUSQVARNA two-stroke oil. 1:33 (3%) with oils class JASO FB or ISO EGB formulated for air-cooled, two-stroke engines. Petrol, litre Two-stroke oil, litre 2% (1:50) 0,10 0,20 0,30 0,40 3% (1:33) 0,15 0,30 0,45 0,60
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). Finish by cutting from above so that the two cuts meet. WARNING! Never attempt to cut logs while they are in a pile or when a couple of logs are lying together. Such procedures drastically increase the risk of kickback which can result in a serious or fatal injury.
If you have a pile of logs, each log you attempt to cut should be removed from the pile, placed on a saw horse or runners and cut individually. Remove the cut pieces from the cutting area. By leaving them in the cutting area, you increase the risk for inadvertently getting a kickback, as well as increasing the risk of losing your balance while working.
The log is supported at both ends. There is a high risk that the chain will jam.
Start by cutting from above (about 1/3 of the way through). Finish by cutting from below so that the two cuts meet.
The log is lying on the ground. There is little risk of the chain jamming or the object splitting. However there is a risk that the chain will touch the ground when you nish the cut.
Tree felling technique
IMPORTANT! It takes a lot of experience to fell a tree. Inexperienced users of chain saws should not fell trees. Do not attempt any task 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.
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.
If it is possible (can you turn the log?) stop cutting about 2/3 of the way through the log.
Felling direction The aim is to fell the tree in a position where you can limb and cross-cut the log as easily as possible. You want it to fall in a location where you can stand and move about safely. Once you have decided which way you want the tree to fall you must judge which way the tree would fall naturally. Several factors affect this: Lean of the tree Bend Wind direction Arrangement of branches Weight of snow Obstacles within the reach of the tree: for example, other trees, power lines, roads and buildings. Look for signs of damage and rot in the stem, this makes it more probably that the tree will break and start to fall before you expect it to. Remove any undergrowth from the base of the tree and check the area for obstacles (stones, branches, holes, etc.) so that you have a clear path of retreat when the tree starts to fall. Your path of retreat should be roughly 135 degrees away from the intended felling direction. Clearing the trunk and preparing your retreat Delimb the stem up to shoulder height. It is safer to work from the top down and to have the tree between you and the saw.
You may nd you are forced to let the tree fall in its natural direction because it is impossible or dangerous to try to make it fall in the direction you rst intended. Another very important factor, which does not affect the felling direction but does affect your safety, is to make sure the tree has no damaged or dead branches that might break off and hit you during felling. The main point to avoid is letting the tree fall onto another tree. It is very dangerous to remove a trapped tree and there is high accident risk. See instructions under the heading Freeing a tree that has fallen badly.
Danger zone Retreat path Felling direction
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. IMPORTANT! During critical felling operations, hearing protectors should be lifted immediately when sawing is completed so that sounds and warning signals can be heard. 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.
Next make the bottom cut so that it nishes exactly at the end of the top cut. The felling hinge controls the direction that the tree falls in.
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.
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.
What is kickback?
The word kickback is used to describe the sudden reaction that causes the chain saw and bar to jump off an object when the upper quadrant of the tip of the bar, known as the kickback zone, touches an object.
Decide which is the safest way to release the tension and whether you are able to do it safely. In complicated situations the only safe method is to put aside your chain saw and use a winch. General advice: Position yourself so that you will be clear of the tree or branch when the tension is released.
Make one or more cuts at or near the point of maximum tension. Make as many cuts of sufcient depth as
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. 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.
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.
The user must only carry out the maintenance and service work described in this Operators Manual. More extensive work must be carried out by an authorised service workshop.
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.
Your Husqvarna product has been designed and manufactured to specications that reduce harmful emissions.
The carburettor governs the engines speed via the throttle control. Air and fuel are mixed in the carburettor. The air/fuel mixture is adjustable. Correct adjustment is essential to get the best performance from the machine. 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.
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.
Basic settings and running in
The basic carburettor settings are adjusted during testing at the factory. Fine adjustment should be carried out by a skilled technician. Rec. idle speed: See the Technical data section.
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. Regularly check that the brake band is at least 0.6 mm thick at its thinnest point. Checking the front hand guard
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.
Make sure the front hand guard is not damaged and that there are no visible defects such as cracks.
Correctly adjusted carburettor
When the carburettor is correctly adjusted the machine accelerates without hesitation and 4-cycles a little at full throttle. 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. Move the front hand guard forwards and back to make sure it moves freely and that it is securely anchored to the clutch cover.
Checking the inertia brake release 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.
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.
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 at least a further 1/2 turn when the starter cord is pulled all the way out.
Replacing the starter cord
Loosen the screws that hold the starter against the crankcase and remove the starter.
Pull out the cord approx. 30 cm and hook it into the notch in the rim of the pulley. Release the recoil spring by letting the pulley rotate slowly backwards.
Stretch the line with the handle. Move your thumb and release the line. See the gure below.
Replacing the return and drive springs
Recoil spring (A) Lift up the starter pulley. See instructions under the heading Changing a broken or worn starter cord. Remember that the recoil spring is coiled under tension in the starter housing. Remove the cassette with the recoil spring from the starter. Lubricate the recoil spring with light oil. Fit the cassette with recoil spring in the starter. Fit the starter pulley and tension the recoil spring.
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.
Drive disc spring (B) Undo the bolt in the centre of the pulley and remove the drive disc and the drive disc spring. Replace the drive disc spring and t the drive disc above the 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 lter according to working conditions, weather, season, etc. Contact your dealer for advice.
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.
