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. 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 • • • This movement activates a spring-loaded mechanism that tightens the brake band (C) around the engine drive system (D) (clutch drum). • 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 firmly and not let go.
GENERAL SAFETY PRECAUTIONS Will my hand always activate the chain brake during a kickback? No. It takes a certain force to move the hand guard forward. If your hand only lightly touches the front guard or slips over it, the force may not be enough to trigger the chain brake. You should also maintain a firm grip of the chain saw handles while working.
GENERAL SAFETY PRECAUTIONS 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. ! WARNING! Never use a saw without a muffler, or with a damaged muffler. A damaged muffler may substantially increase the noise level and the fire hazard. Keep fire fighting equipment handy.
GENERAL SAFETY PRECAUTIONS 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 filing instructions. See instructions under the heading Technical data. • Bar groove width (inches/mm). The groove in the bar must match the width of the chain drive links. • Chain oil hole and hole for chain tensioner.
GENERAL SAFETY PRECAUTIONS When you sharpen a cutting tooth there are four important factors to remember. 1 Filing angle 2 Cutting angle 3 File position • Always file cutting teeth from the inside face. Reduce the pressure on the return stroke. File all the teeth on one side first, then turn the chain saw and file the teeth on the other side. • 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.
GENERAL SAFETY PRECAUTIONS through the depth gauge tool. The depth gauge setting is correct when you no longer feel resistance as you draw the file along the depth gauge tool. Lubricating cutting equipment ! WARNING! Poor lubrication of cutting equipment may cause the chain to snap, which could lead to serious, even fatal injuries. Chain oil Tensioning the chain ! WARNING! A slack chain may jump off the bar and cause serious or even fatal injury.
GENERAL SAFETY PRECAUTIONS If the chain lubrication is not working: • Checking wear on cutting equipment Check that the oil channel in the bar is not obstructed. Clean if necessary. Check the chain daily for: • Check that the groove in the edge of the bar is clean. Clean 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.
GENERAL SAFETY PRECAUTIONS • 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.
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. Gasoline, litre WARNING! Always ensure there is adequate ventilation when handling fuel.
FUEL HANDLING Fueling ! WARNING! Taking the following precautions, will lessen the risk of fire: Fuel safety • Never refuel the machine while the engine is running. • Make sure there is plenty of ventilation when refuelling or mixing fuel (gasoline and 2-stroke oil). • Move the machine at least 3 m from the refuelling point before starting it. • 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.
STARTING AND STOPPING Starting and stopping ! Warm engine 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. 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 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. Make sure you are standing firmly and that there is nothing in the way that might make you trip or lose your balance. Lack of concentration can lead to kickback if the kickback zone of the bar accidentally touches a branch, nearby tree or some other object.
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 High speed jet H Checking the front hand guard 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. Make sure the front hand guard is not damaged and that there are no visible defects such as cracks. CAUTION! If the high speed jet is screwed in too far, it may damage the piston/cylinder.
MAINTENANCE Grasp the chain saw firmly, wrapping your fingers and thumbs around the handles. Chain catcher Check that the chain catcher is not damaged and is firmly attached to the body of the chain saw. 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.
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, starter cord or the drive disc spring. 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 Fitting the starter • • To fit the starter, first 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. Hook the starter cord in the notch in the pulley and turn the starter pulley about 2 turns clockwise.
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). • Incorrect carburetor adjustment. • An incorrect fuel mixture (too much or incorrect type of oil). • A dirty air filter. These factors cause deposits on the spark plug electrodes, which may result in operating problems and starting difficulties.
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 carburetor. The cooling system consists of: Special measures are therefore often required: 1 Air intake on the starter. • 2 Air guide plate.
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.
