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 Husqvarna 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 reduce the risk of moving chain accidentally hitting your leg or anyone or anything close by. Take care when using your saw and make sure the kickback zone of the bar never touches any object. • The chain brake (A) can either be activated manually (by your left hand) or automatically by the inertia release mechanism. • To release the chain brake pull the front hand guard backwards, towards the front handle. • Kickback can be very sudden and violent.
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 lockout The throttle lockout 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 minimize 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 • 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. ! WARNING! Any contact with a rotating saw chain can cause extremely serious injuries. Some terms that describe the bar and chain • Maintain the correct depth gauge setting! Follow our instructions and use the recommended depth gauge clearance. Too large a clearance increases the risk of kickback.
GENERAL SAFETY PRECAUTIONS • Drive link width (mm/inches) • Number of drive links. 3 File position 4 Round file diameter 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. Sharpening your chain and adjusting depth gauge setting General information on sharpening cutting teeth • • Never use a blunt chain.
GENERAL SAFETY PRECAUTIONS • General advice on adjusting depth gauge setting • resistance as you draw the file along the depth gauge tool. File all the teeth to the same length. When the length of the cutting teeth is reduced to 4 mm (5/32") the chain is worn out and should be replaced. Tensioning the chain When you sharpen the cutting tooth (A) the depth gauge setting (C) will decrease.
GENERAL SAFETY PRECAUTIONS throttle you should see a distinct line of oil on the light surface. The position of the chain tensioning screw on our chain saws varies from model to model. See instructions under the heading What is what? to find out where it is on your model. Lubricating cutting equipment ! WARNING! Poor lubrication of cutting equipment may cause the chain to snap, which could lead to serious, even fatal injuries.
GENERAL SAFETY PRECAUTIONS B Rim sprocket (replaceable) • 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. • To prolong the life of the bar you should turn it over daily. Regularly check the degree of wear on the drive sprocket. Replace if wear is excessive. Replace the drive sprocket whenever you replace the chain.
ASSEMBLY Fitting the bar and chain ! 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. The chain is correctly tensioned when it does not sag from the underside of the bar, but can still be turned easily by hand. Hold up the bar tip and tighten the bar nuts with the combination spanner.
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 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. ! 1:33 (3%) with oils class JASO FB or ISO EGB formulated for air-cooled, two-stroke engines.
FUEL HANDLING Fuelling ! • Move the machine at least 3 m from the refuelling point before starting it. WARNING! Taking the following precautions, will lessen the risk of fire: Min. 3 m (10 ft) Do not smoke and do not place any hot objects in the vicinity of fuel. • Never start the machine: 1 When refuelling, open the fuel cap slowly so that any excess pressure is released gently. 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 ! the machine has started the valve will automatically return to its original setting. WARNING! Note the following before starting: A B 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. Place the machine on firm ground.
STARTING AND STOPPING prevents unnecessary wear to the clutch, clutch drum and brake band. • Observe your surroundings and make sure that there is no risk of people or animals coming into contact with the cutting equipment. • 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 6 5 7 4 3 8 2 1 9 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. 10 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.
WORKING TECHNIQUES 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. 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. Never carry or hang the saw by the trigger! This could damage the mechanism and disable the chain brake.
WORKING TECHNIQUES the saw chain is jamming, the saw may be pushed back at you. Limbing = Cutting branches off a felled tree. Splitting = When the object you are cutting breaks off before the cut is complete. There are five important factors you should consider before making a cut: 8 Cutting with the bottom edge of the bar, i.e. from the top of the object downwards, is known as cutting on the pull stroke.
WORKING TECHNIQUES Cut difficult branches piece by piece. 1 Turn the log and finish the cut from the opposite side. 2 3 The log is supported at one end. There is a high risk that it will split. Cutting ! WARNING! Never attempt to cut logs while they are in a pile or when a couple of logs are lying together. Such procedures drastically increase the risk of kickback which can result in a serious or fatal injury.
WORKING TECHNIQUES Make sure that no-one else is in this ”risk zone” before or during felling. there is high accident risk. See instructions under the heading Freeing a tree that has fallen badly. Felling direction 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.
WORKING TECHNIQUES Felling ! Make the felling cut about 3-5 cm (1.5-2 inches) above the bottom directional 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! Felling is done using three cuts. First you make the directional cuts, which consist of the top cut and the bottom cut, then you finish with the felling cut. By placing these cuts correctly you can control the felling direction very accurately.
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. 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 If you must cut across tree/limb, make two to three cuts, one inch apart, one to two inches deep. Kickback only occurs if the kickback zone of the bar touches an object. 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. How to avoid kickback ! WARNING! Kickback can happen very suddenly and violently; kicking the chain saw, bar and chain back at the user.
MAINTENANCE General and if they are turned anti-clockwise the ratio becomes richer (more fuel). A lean mixture gives a higher engine speed and a rich mixture gives a lower engine speed. 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).
MAINTENANCE ! WARNING! Contact your servicing dealer, if the idle speed setting cannot be adjusted so that the chain stops. Do not use the chain saw until it has been properly adjusted or repaired. 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.
MAINTENANCE Checking the right-hand brake trigger let go of the front handle. The chain should stop immediately. Check that the right hand guard is not damaged and that there are no visible defects, such as cracks. Throttle lockout • Make sure the throttle control is locked at the idle setting when the throttle lockout is released. Never carry or hang the saw by the trigger! This could damage the mechanism and disable the chain brake.
MAINTENANCE necessary with an aluminium chain catcher (is available as spare part). Stop switch Start the engine and make sure the engine stops when you move the stop switch to the stop setting. 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.
MAINTENANCE use a muffler if the spark arrestor mesh is missing or defective. • Pull out the cord approx. 30 cm and hook it into the notch in the rim of the pulley. Release the recoil spring by letting the pulley rotate slowly backwards. • 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.
MAINTENANCE • Lubricate the recoil spring with light oil. Fit the cassette with recoil spring in the starter. Fit the starter pulley and tension the recoil spring. Spark plug 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.
MAINTENANCE Lubrication involves engine oil dripping into the centre of the clutch drum as it rotates. 5 Cylinder cover (directs cold air over the cylinder). 5 4 3 1 Adjustment of the oil pump (346XP/353) 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.
MAINTENANCE electrical heating coils. These are supplied with electricity from a generator built into the chain saw. When the switch is pushed upwards, the heat is switched on. When the switch is pushed downwards, the heat is switched off. Electrical carburettor heating Twist the winter flap so that preheated air from the cylinder can pass into the carburettor space preventing icing of the air filter, etc.
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 0.6 mm (0,024 inch) remains at the most worn point.
