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 Vibration damping system Muffler Your machine is equipped with a vibration damping system that is designed to reduce vibration and make operation easier. The muffler is designed to keep noise levels to a minimum and to direct exhaust fumes away from the user. ! The machine′s vibration damping system reduces the transfer of vibration between the engine unit/cutting equipment and the machine′s handle unit.
GENERAL SAFETY PRECAUTIONS General rules Chain • A chain is made up of a number of links, which are available in standard and low-kickback versions. Only use cutting equipment recommended by us! See instructions under the heading Technical data. IMPORTANT! No saw chain design eliminates the danger of kickback. • Keep the chain’s cutting teeth properly sharpened! Follow our instructions and use the recommended file gauge. A damaged or badly sharpened chain increases the risk of accidents.
GENERAL SAFETY PRECAUTIONS Chain • • 3 File position 4 Round file diameter Chain pitch (inches) Drive link width (mm/inches) It is very difficult to sharpen a chain correctly without the right equipment. We recommend that you use our file gauge. This will help you obtain the maximum kickback reduction and cutting performance from your chain. • Number of drive links.
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. 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. Remove the bar nuts and remove the clutch cover (chain brake). Take off the transportation ring (A). Fit the bar over the bar bolts.
FUEL HANDLING Fuel Mixing ratio CAUTION! The machine is equipped with a two-stroke engine and must always been run using a mixture of gasoline and two-stroke engine 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 ! 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. Tighten the fuel cap carefully after refuelling. • Never start the machine: Always move the machine away from the refuelling area before starting. 1 If you have spilt fuel or chain oil on the machine.
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. 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. Use the same procedure as for starting a cold engine but without setting the choke control in the choke position.
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 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. 6 Before moving your chain saw switch off the engine and lock the chain using the chain brake.
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 Checking the brake trigger • Check that the throttle control and throttle lock move freely and that the return springs work properly. • Start the chain saw and apply full throttle. Release the throttle control and check that the chain stops and remains stationary. If the chain rotates when the throttle control is in the idle position you should check the carburetor idle adjustment. Place the chain saw on firm ground and start it.
MAINTENANCE Stop switch Note! The mesh must be replaced if it is damaged. If the mesh is blocked the machine will overheat and this will cause damage to the cylinder and piston. Never use a machine with a muffler that is in poor condition. Never use a muffler if the spark arrestor mesh is missing or defective. Start the engine and make sure the engine stops when you move the stop switch to the stop setting.
MAINTENANCE • Undo the screw in the centre of the pulley and remove the pulley. Insert and fasten a new starter cord to the pulley. Wind approx. 3 turns of the starter cord onto the pulley. Connect the pulley to the recoil spring so that the end of the spring engages in the pulley. Fit the screw in the center of the pulley. Insert the starter cord through the hole in the starter housing and the starter handle. Make a secure knot in the end of the starter cord.
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). When lubricating, remove the clutch cover by loosening the two bar nuts. Lay the saw on its side with the clutch drum upwards. • Incorrect carburetor adjustment. • An incorrect fuel mixture (too much or incorrect type of oil). • A dirty air filter.
MAINTENANCE Cooling system Temperature 0°°C (32°°F) or colder: To keep the working temperature as low as possible the machine is equipped with a cooling system. For running the machine in cold weather or powder snow, a special cover is available, which is mounted on the starter housing. This reduces the intake of cold air and prevents large amounts of snow from being sucked in. The cooling system consists of: 1 Air intake on the starter. 2 Air guide plate. 3 Fins on the flywheel.
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.
