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.

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.
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. See instructions under the heading Tensioning the chain. 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.
FUEL HANDLING Fuel Mixing ratio Note! The machine is equipped with a two-stroke engine and must always be run using a mixture of gasoline 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. ! 1:50 (2%) for all engines.
FUEL HANDLING Fueling ! 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! Pull the front hand guard towards the front handle. The chain brake is now disengaged. Your saw is 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 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. 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 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. 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 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.
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 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. There are methods for felling trees with a diameter larger than the bar length. However these methods involve a much greater risk that the kickback zone of the bar will come into contact with the tree.
WORKING TECHNIQUES 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.
MAINTENANCE General Basic settings and running in The user must only carry out the maintenance and service work described in this manual. The basic carburetor settings are adjusted during testing at the factory. Avoid running at a too high speed for extended periods during the first 10 hours. IMPORTANT! Any maintenance other than that described in this manual must be carried out by your servicing dealer (retailer).
MAINTENANCE Correctly adjusted carburetor Checking the inertia brake release When the carburetor is correctly adjusted the machine accelerates without hesitation and the machine 4-cycles a little at max. speed. It is also important that the chain does not rotate at idle. If the L-jet is set too lean it may cause starting difficulties 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.
MAINTENANCE Throttle lock Right hand guard • Make sure the throttle control is locked at the idle setting when the throttle lock is released. Check that the right hand guard is not damaged and that there are no visible defects, such as cracks. • Press the throttle lock and make sure it returns to its original position when you release it. Vibration damping system Regularly check the vibration damping units for cracks or deformation.
MAINTENANCE Muffler Starter ! Never use a machine that has a faulty muffler. 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. Changing a broken or worn starter cord Regularly check that the muffler is securely attached to the machine.
MAINTENANCE Tensioning the recoil spring • Air filter 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. The air filter 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.
MAINTENANCE Lubricating the bar tip sprocket Adjustment of the oil pump Lubricate the bar tip sprocket each time you refuel. Use the special grease gun and a good quality bearing grease. The oil pump is adjustable. Adjustments are made by turning the screw using a screwdriver or combination spanner. The machine is supplied from the factory with the screw set to position 2. Turning the screw clockwise will reduce the oil flow and turning the screw anti-clockwise will increase the oil flow.
MAINTENANCE ”Air Injection” centrifugal cleaning Centrifugal cleaning means the following: All air to the carburetor passes through the starter. Dirt and dust is pushed out by the cooling fan. For temperatures below -5°C (23°F) and/or in snow conditions there is also: • a special cover (A) for the starter housing • a winter plug (B) for the air nozzle that is fitted as shown. IMPORTANT! In order to maintain operation of the centrifugal cleaning system it must be regularly maintained.
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.
