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 Charles 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 water-powered 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. Important IMPORTANT! The machine is only designed for cutting wood. • Refuel and start the chain saw. See the instructions under the headings Fuel Handling and Starting and Stopping. You should only use the saw with the bar and chain combinations we recommend in the chapter Technical data.
GENERAL SAFETY PRECAUTIONS chain saw usage if possible. Your dealer, forestry school or your library can provide information about which training materials and courses are available. • Fire Extinguisher and Shovel Generally clothes should be close-fitting without restricting your freedom of movement. IMPORTANT! Sparks can come from the muffler, the bar and chain or other sources. Always have fire extinguishing tools available if you should need them. Help prevent forest fires.
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. • • • • To release the chain brake pull the front hand guard backwards, towards the front handle. • Kickback can be very sudden and violent. Most kickbacks are minor and do not always activate the chain brake.
GENERAL SAFETY PRECAUTIONS • In the felling position the left hand is in a position that makes manual activation of the chain brake impossible. With this type of grip, that is when the left hand is placed so that it cannot affect the movement of the front hand guard, the chain brake can only be activated by the inertia action. Throttle lock The throttle lock is designed to prevent accidental operation of the throttle control. When you press the lock (A) (i.e.
GENERAL SAFETY PRECAUTIONS 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 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 mesh. Cutting hardwoods (most broadleaf trees) creates more vibration than cutting softwoods (most conifers).
GENERAL SAFETY PRECAUTIONS • • 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) • 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. • Number of drive links.
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. ! WARNING! A slack chain may jump off and cause serious or even fatal injury.
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. • 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. The chain should be tensioned until it does not sag from the underside of the bar. 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. Remove the bar nuts and remove the clutch cover (chain brake).
FUEL HANDLING Fuel Mixing ratio Note! The machine is equipped with a two-stroke engine and must always be run using a mixture of petrol 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. ! 1:50 (2%) with HUSQVARNA two-stroke oil.
FUEL HANDLING Fuelling ! WARNING! Taking the following precautions, will lessen the risk of fire: • Never start the machine: 1 If you have spilt fuel or chain oil on the machine. Wipe off the spillage and allow remaining fuel to evaporate. 2 If you have spilt 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. Check regularly for leaks from the fuel cap and fuel lines.
STARTING AND STOPPING Starting and stopping ! 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. 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 Note! Reactivate the chain brake by pushing the front hand guard back towards the front handle. The chain saw is now ready for use. ! • • Always hold the saw with both hands. The right hand should be on the rear handle, and the left hand on the front handle. All people, whether right or left handed, should use this grip. Use a firm grip with thumbs and fingers encircling the chain saw handles.
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. , 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 lock works correctly and is not damaged.
WORKING TECHNIQUES 5 6 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. 3 Most kickback accidents happen during limbing.
WORKING TECHNIQUES 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 on the push stroke. 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. 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 When limbing thick branches you should use the same approach as for cutting. If it is possible (can you turn the log?) stop cutting about 2/3 of the way through the log. Cut difficult branches piece by piece. 1 2 3 The log is supported at one end. There is a high risk that it will split. Cutting ! Turn the log and finish the cut from the opposite side. WARNING! Never attempt to cut logs while they are in a pile or when a couple of logs are lying together.
WORKING TECHNIQUES 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! 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.
WORKING TECHNIQUES Felling ! Felling cut WARNING! Unless you have special training we advise you not to fell trees with a diameter larger than the bar length of your saw! 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. Felling is done using three cuts.
WORKING TECHNIQUES 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. Never work in the risk zone of the hanging trapped tree. 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 find out which lengths of bar are recommended for your saw.
WORKING TECHNIQUES Never cut straight through a tree or branch that is in tension! Kickback only occurs if the kickback zone of the bar touches an object. 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. Limbing ! Cut tree/limb from outside the bend, after tension has been released.
MAINTENANCE General • 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 anticlockwise the ratio becomes richer (more fuel). A lean mixture gives a higher engine speed and a rich mixture gives a lower engine speed. • The T-screw regulates the throttle setting at idle speed.
MAINTENANCE High speed jet H • 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 anticlockwise the ratio becomes richer (more fuel). A lean mixture gives a higher engine speed and a rich mixture gives a lower engine speed. • The T-screw regulates the throttle setting at idle speed.
MAINTENANCE Low speed jet L Correctly adjusted carburettor 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. 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.
MAINTENANCE Checking the inertia brake release Throttle lock 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. • Make sure the throttle control is locked at the idle setting when the throttle lock is released. • Press the throttle lock and make sure it returns to its original position when you release it.
MAINTENANCE Right hand guard Muffler 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 muffler. Vibration damping system Regularly check that the muffler 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.
MAINTENANCE Starter Tensioning the recoil spring • ! 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. 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. Care must be exercised when replacing the return spring or the starter cord.
MAINTENANCE Air filter Lubricating the bar tip sprocket The air filter must be regularly cleaned to remove dust and dirt in order to avoid: Lubricate the bar tip sprocket each time you refuel. Use the special grease gun and a good quality bearing grease. • Carburettor malfunctions • Starting problems • Loss of engine power • Unnecessary wear to engine parts. • Excessive fuel consumption. • Remove the air filter after taking off the air filter cover.
MAINTENANCE Cooling system Winter use Running problems can occur when using the machine in the cold and snowy conditions caused by: To keep the working temperature as low as possible the machine is equipped with a cooling system. • Too low engine temperature. • Icing of the air filter and carburettor. The cooling system consists of: Special measures are therefore often required: 1 Air intake on the starter. • 2 Air guide plate.
MAINTENANCE Heated handles (357 XPG, 359 G) On models with the designation XPG/G, the front as well as the rear handle are equipped with electric heating coils. These are supplied with electricity from a built-in generator on the chain saw. When the switch is pushed downwards, the heat is switched on. When the switch is pushed upwards, the heat is switched off. Electrical carburettor heating (357 XPG, 359 G) On models with the designation CARBURETOR HEATING there is an electrically heated carburetor.
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 Clean the outside of the machine. Weekly maintenance Monthly maintenance 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 0.6 mm (0,024 inch) remains at the most worn point.
