SAFETY INSTRUCTIONS Personal protective equipment ! WARNING! Most chain saw accidents happen when the chain touches the operator. You must use approved personal protective equipment whenever you use the machine. Personal protective equipment cannot eliminate the risk of injury but it will reduce the degree of injury if an accident does happen. Ask your dealer for help in choosing the right equipment. ! WARNING! Long or continuous exposure to high noise levels may cause permanent hearing impairment.
SAFETY INSTRUCTIONS Chain brake and front hand guard • You can also use the chain brake as a temporary brake when you change position or if you put the chain saw down for a short time! Apart from the fact that a chain saw with a chain brake greatly reduces the risk of accidents due to kickback, you should also apply the chain brake manually if there is a risk of the chain accidentally hitting anyone or anything close by.
SAFETY INSTRUCTIONS In some cases the chain brake can be activated by your right hand. Right hand guard Apart from protecting your hand if the chain jumps or snaps, the right hand guard stops branches and twigs from interfering with your grip on the rear handle. • • During felling your left hand grasps the front handle in such a way that it cannot activate the chain brake. In this position, i.e.
SAFETY INSTRUCTIONS Stop switch Use the stop switch to switch off the engine. Checking, maintaining and servicing the machine′s safety equipment ! Muffler The muffler is designed to keep noise levels to a minimum and to direct exhaust fumes away from the user. WARNING! All servicing and repair work on the machine requires special training. This is especially true of the machine′s safety equipment. If your machine fails any of the checks described below you must contact your service agent.
SAFETY INSTRUCTIONS Checking the inertia brake release Grasp the chain saw firmly, wrapping your fingers and thumbs around the handles. Hold the chain saw over a stump or other firm object. Let go of the front handle so that the bar drops towards the stump as the chain saw rotates around the rear handle. 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.
SAFETY INSTRUCTIONS Right hand guard If the muffler on your machine is fitted with a spark arrestor mesh this must be cleaned regularly. A blocked mesh will cause the engine to overheat and may lead to serious damage. Check that the right hand guard is not damaged and that there are no visible defects, such as cracks. Never use a muffler if the spark arrestor mesh is missing or defective. Vibration damping system Regularly check the vibration damping units for cracks or deformation.
SAFETY INSTRUCTIONS Cutting equipment designed to minimise kickback ! WARNING! Faulty cutting equipment or the wrong combination of bar and chain increases the risk of kickback! Use only the bar and chain combinations that we recommend. See the Technical data section. The only way to avoid kickback is to make sure that the kickback zone of the bar never touches anything. Bar • Length (inches/cm) • Number of teeth on bar tip sprocket (T). Small number = small tip radius = low risk of kickback.
SAFETY INSTRUCTIONS Sharpening your chain and adjusting raker clearance ! WARNING! The risk of kickback is increased with a badly sharpened chain! 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. General information on sharpening cutting teeth • • Never use a blunt chain.
SAFETY INSTRUCTIONS General advice on setting raker clearance • Tensioning the chain When you sharpen the cutting teeth you reduce the raker clearance (=cutting depth). To maintain optimal cutting performance you must file back the raker lip to the recommended height. See the Technical data section to find the raker clearance for your particular chain. ! WARNING! A slack chain may jump off and cause serious or even fatal injury. The more you use a chain the longer it becomes.
SAFETY INSTRUCTIONS Lubricating cutting equipment ! WARNING! Poor lubrication of cutting equipment may cause the chain to snap, which could lead to serious, even fatal injuries. If the chain lubrication is not working: • Check that the oil channel in the bar is not obstructed. Clean if necessary. • Check that the groove in the edge of the bar is clean. Clean if necessary. • Check that the bar tip sprocket turns freely and that the lubricating hole in the tip sprocket is not blocked.
SAFETY INSTRUCTIONS Checking wear on cutting equipment • 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. Check the chain daily for: • Visible cracks in rivets and links. • Whether the chain is stiff. • Whether rivets and links are badly worn.
SAFETY INSTRUCTIONS Kickback always occurs in the cutting plane of the bar. Normally the chain saw and bar are thrown backwards and upwards towards the user. However, the chain saw may move in a different direction depending on the way it was being used when the kickback zone of the bar touched the object. 5 You must have a steady stance in order to have full control over the chain saw. Never work standing on a ladder, in a tree or where you do not have firm ground to stand on.
SAFETY INSTRUCTIONS General safety precautions • Chain saws are designed solely for cutting wood. The only accessories you may use with this engine unit are the combinations of bars and chains we recommend in the Technical data section. • Never use the machine if you are tired, if you have drunk alcohol, or if you are taking medication that could affect your vision, your judgement or your co-ordination. 7 Check that the muffler is securely attached and not damaged.
SAFETY INSTRUCTIONS General working instructions Fuel safety ! ! ! WARNING! The catalytic converter muffler gets very hot during and after use. This also applies during idling. Be aware of the fire hazard, especially when working near flammable substances and/or vapours. WARNING! Fuel and fuel vapour are highly flammable. Take care when handling fuel and chain oil. Be aware of the risks of fire, explosion and those associated with inhalation. • Never refuel the machine while the engine is running.
SAFETY INSTRUCTIONS • • Take the utmost care when cutting through branches or logs that are in tension. A log or branch that is in tension can suddenly spring back into its natural position before or after you cut it. If you stand on the wrong side or start cutting in the wrong place it may strike you or your chain saw, so that you lose control. Both situations could cause serious injury. Before moving your chain saw switch off the engine and lock the chain using the chain brake.
SAFETY INSTRUCTIONS Cut all the way through the log from above. Avoid letting the chain touch the ground as you finish the cut. Maintain full throttle but be prepared for what might happen. Limbing When limbing thick branches you should use the same approach as for cutting. Cut difficult branches piece by piece. 1 2 3 If it is possible (can you turn the log?) stop cutting about 2/3 of the way through the log. Tree felling technique ! Turn the log and finish the cut from the opposite side.
SAFETY INSTRUCTIONS You may find you are forced to let the tree fall in its natural direction because it is impossible or dangerous to try to make it fall in the direction you first intended. The directional cuts should run 1/4 of the diameter through the trunk and the angle between the top cut and bottom cut should be 45°.
SAFETY INSTRUCTIONS All control over the felling direction is lost if the felling hinge is too narrow or non-existent, or if the directional cuts and felling cut are badly placed. Cutting the trunk into logs See instructions under the heading Basic cutting technique. Freeing a tree that has fallen badly Freeing a ”trapped tree” 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.

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. 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.
FUEL HANDLING Fuel Mixing ratio CAUTION! The machine is equipped with a two-stroke engine and must always been run using a mixture of petrol and twostroke 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.
FUEL HANDLING Chain oil • The chain lubrication system is automatic and we recommend the use of special oil (chain oil) with good adhesion characteristics. Fuelling ! WARNING! Taking the following precautions, will lessen the risk of fire: Do not smoke or place hot objects near fuel. Always shut off the engine before refuelling. When refuelling, open the fuel cap slowly so that any excess pressure is released gently. Tighten the fuel cap carefully after refuelling.
STARTING AND STOPPING Starting and stopping ! Warm engine WARNING! Note the following before 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. Always move the machine away from the refuelling area before starting. Place the machine on firm ground. Make sure you have a secure footing and that the chain cannot touch anything. Keep people and animals well away from the working area.
STARTING AND STOPPING Reactivate the chain brake by pushing the front hand guard back towards the front handle. The chain saw is now ready for use. Stopping Stop the engine by switching off the ignition.
MAINTENANCE Carburettor adjustment ! Due to existing environmental and emissions legislation your chain saw is equipped with movement limiters on the carburettor adjuster screws. These limit the adjustment possibilities to a maximum of a 1/2 turn. Fine adjustment H L 1/2 1/2 Your Husqvarna product has been designed and manufactured to specifications that reduce harmful emissions.
MAINTENANCE 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. CAUTION! If the high speed jet is screwed in too far, it may damage the piston/cylinder.
MAINTENANCE Fitting the starter Spark plug • 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. The spark plug condition is influenced by: • Fit and tighten the screws that hold the starter. • Incorrect carburettor adjustment. • Wrong fuel mixture (too much oil). • A dirty air filter.
MAINTENANCE WARNING! The catalytic converter muffler gets very hot during and after use. This also applies during idling. Be aware of the fire hazard, especially when working near flammable substances and/or vapours.
MAINTENANCE Heated handles Temperature -5°C or colder: (346XPG, 353G) On models with the model code XPG/G both the front handle bar and the rear handle are equipped with 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.
