INTRODUCTION Dear customer! Congratulations on your choice to buy a Husqvarna product! Husqvarna is based on a tradition that dates back to 1689, when the Swedish King Karl XI ordered the construction of a factory on the banks of the Huskvarna River, for production of muskets. The location was logical, since water power was harnessed from the Huskvarna River to create the waterpowered plant.

GENERAL SAFETY PRECAUTIONS Before using a new chain saw • Please read this manual carefully. • Check that the cutting equipment is correctly fitted 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 sufficient chain oil has reached the chain. See instructions under the heading Lubricating cutting equipment.
GENERAL SAFETY PRECAUTIONS Always use common sense It is not possible to cover every conceivable situation you can face when using a chain saw. Always exercise care and use your common sense. Avoid all situations which you consider to be beyond your capability. If you still feel uncertain about operating procedures after reading these instructions, you should consult an expert before continuing. Do not hesitate to contact your dealer or us if you have any questions about the use of the chain saw.
GENERAL SAFETY PRECAUTIONS • 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. • This movement activates a spring-loaded mechanism that tightens the brake band (C) around the engine drive system (D) (clutch drum). • The front hand guard is not designed solely to activate the chain brake.
GENERAL SAFETY PRECAUTIONS of the front hand guard, the chain brake can only be activated by the inertia action. Throttle lockout The throttle lockout is designed to prevent accidental operation of the throttle control. When you press the lock (A) (i.e. when you grasp the handle) it releases the throttle control (B). When you release the handle the throttle control and the throttle lockout both move back to their original positions.
GENERAL SAFETY PRECAUTIONS 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 fires. These areas are sometimes subject to government rules requiring among other things the muffler must be equipped with an approved type of spark arrestor screen. Cutting hardwoods (most broadleaf trees) creates more vibration than cutting softwoods (most conifers).
GENERAL SAFETY PRECAUTIONS gauge clearance. Too large a clearance increases the risk of kickback. Husqvarna. See instructions under the heading Technical Data for a list of replacement bar and chain combinations we recommend. Bar • • 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.
GENERAL SAFETY PRECAUTIONS Sharpening your chain and adjusting depth gauge setting See instructions under the heading Technical data for information about sharpening your chain. 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.
GENERAL SAFETY PRECAUTIONS General advice on adjusting depth gauge setting • Tensioning the chain 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 filed down to achieve the recommended depth gauge setting. See instructions under the heading Technical data to find the correct depth gauge setting for your particular chain.
GENERAL SAFETY PRECAUTIONS Lubricating cutting equipment Checking chain lubrication • ! WARNING! Poor lubrication of cutting equipment may cause the chain to snap, which could lead to serious, even fatal injuries. 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.
GENERAL SAFETY PRECAUTIONS Chain drive sprocket Bar The clutch drum is fitted with one of the following drive sprockets: Check regularly: • Whether there are burrs on the edges of the bar. Remove these with a file if necessary. • Whether the groove in the bar has become badly worn. Replace the bar if necessary. 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.
ASSEMBLY Fitting the bar and chain ! Tension the chain by turning the chain tensioning screw clockwise using the combination spanner. See instructions under the heading Tensioning the chain. WARNING! Always wear gloves, when working with the chain. Check that the chain brake is in disengaged position by moving the front hand guard towards the front handle. The chain is correctly tensioned when it does not sag from the underside of the bar, but can still be turned easily by hand.
FUEL HANDLING Fuel Note! The machine is equipped with a two-stroke engine and must always be run using a mixture of gasoline and two-stroke oil. It is important to accurately measure the amount of oil to be mixed to ensure that the correct mixture is obtained. When mixing small amounts of fuel, even small inaccuracies can drastically affect the ratio of the mixture. Mixing ratio 1:50 (2%) for all engines. Gasoline, litre WARNING! Always ensure there is adequate ventilation when handling fuel.
FUEL HANDLING Fueling ! • Move the machine at least 10 ft (3 m) from the refuelling point before starting it. • Never start the machine: 1 If you have spilled fuel or chain oil on the machine. Wipe off the spillage and allow remaining fuel to evaporate. 2 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. 3 If the machine is leaking fuel.
STARTING AND STOPPING Starting and stopping ! WARNING! Note the following before starting: Never start a chain saw unless the bar, chain and all covers are fitted correctly. Otherwise the clutch can come loose and cause personal injuries. 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.
STARTING AND STOPPING throttle latch in order to avoid unnecessery wear on the clutch assembly. ! should use this grip. Use a firm grip with thumbs and fingers encircling the chain saw handles. WARNING! Long term inhalation of the engine’s 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 fitted correctly. See instructions under the heading Assembly.
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. , 1 Check that the chain brake works correctly and is not damaged. 2 Check that the rear right hand guard is not damaged. 3 Check that the throttle lockout works correctly and is 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.
WORKING TECHNIQUES 6 Before moving your chain saw switch off the engine and lock the chain using the chain brake. Carry the chain saw with the bar and chain pointing backwards. Fit a guard to the bar before transporting the chain saw or carrying it for any distance. 7 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.
WORKING TECHNIQUES user. If the saw chain is jamming, the saw may be pushed back at you. Terms Cutting = General term for cutting through wood. Limbing = Cutting branches off a felled tree. Splitting = When the object you are cutting breaks off before the cut is complete.
WORKING TECHNIQUES Limbing Turn the log and finish the cut from the opposite side. When limbing thick branches you should use the same approach as for cutting. Cut difficult branches piece by piece. 1 2 3 Start by cutting from below (about 1/3 of the way through). Cutting ! The log is supported at one end. There is a high risk that it will split. Finish by cutting from above so that the two cuts meet.
WORKING TECHNIQUES Felling direction Clearing the trunk and preparing your retreat 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. 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. Once you have decided which way you want the tree to fall you must judge which way the tree would fall naturally.
WORKING TECHNIQUES Next make the bottom cut so that it finishes 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°.
WORKING TECHNIQUES Freeing a tree that has fallen badly necessary to reduce the tension and make the tree or branch break at the point of maximum tension. 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.
WORKING TECHNIQUES 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.
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). 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.
MAINTENANCE 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.
MAINTENANCE Checking the inertia brake release With the engine turned off, hold the chain saw over a stump or other firm object. Let go of the front handle so that the bar drops towards the stump as the chain saw rotates around the rear handle. go of the front handle. The chain should stop immediately. Throttle lockout • Make sure the throttle control is locked at the idle setting when the throttle lockout is released.
MAINTENANCE Chain catcher Stop switch Check that the chain catcher is not damaged and is firmly 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. Right hand guard Check that the right hand guard is not damaged and that there are no visible defects, such as cracks. Vibration damping system Muffler Never use a machine that has a faulty muffler. Regularly check that the muffler is securely attached to the machine.
MAINTENANCE use a muffler if the spark arrestor screen is missing or defective. The muffler 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 fire if directed against dry and combustible material. recoil spring by letting the pulley rotate slowly backwards.
MAINTENANCE Changing a broken recoil spring Air filter • 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. The air filter must be regularly cleaned to remove dust and dirt in order to avoid: • Carburettor malfunctions • Remove the cassette with the recoil spring from the starter. • Starting problems • Loss of engine power Lubricate the recoil spring with light oil.
MAINTENANCE Spark plug Needle bearing lubrication The spark plug condition is influenced by: The clutch drum has a needle bearing on the output shaft. This needle bearing must be lubricated regularly (once a week). CAUTION! Use only high quality bearing grease or engine oil. See instructions under the heading Cutting equipment. • Incorrect carburetor adjustment. • An incorrect fuel mixture (too much or incorrect type of oil). • A dirty air filter.
MAINTENANCE Cooling system Winter use Running problems can occur when using the machine in the cold and snowy conditions caused by: • Too low engine temperature. To keep the working temperature as low as possible the machine is equipped with a cooling system. • Icing of the air filter and carburetor. The cooling system consists of: • 1 Air intake on the starter. 2 Air guide plate. 3 Fins on the flywheel. 4 Cooling fins on the cylinder. 5 Cylinder cover (directs cold air over the cylinder).
MAINTENANCE Electrical carburetor heating (372XPG) On models with the designation CARBURETOR HEATING there is an electrically heated carburetor. Electrically powered heating prevents ice formation in the carburetor. A thermostat regulates the heating so that the carburetor always has the right working temperature. Canada If this chain saw has the model code XPG/G then it is equipped with an electrically heated carburettor. The electrical heating prevents icing in the carburettor.
MAINTENANCE 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 Monthly maintenance Clean the outside of the machine. On chain saws without a catalytic converter, check the cooling system weekly. 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.
