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 • 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. when your left hand is in such a position that it cannot affect the movement of the front hand guard, the chain brake can only be activated by the inertia of the counterweight. Vibration damping system Your machine is equipped with a vibration damping system that is designed to minimize vibration and make operation easier.
SAFETY INSTRUCTIONS Muffler Checking the front hand guard The muffler is designed to keep noise levels to a minimum and to direct exhaust fumes away from the user. Make sure the front hand guard is not damaged and that there are no visible defects such as cracks. ! WARNING! The exhaust fumes from the engine are hot and may contain sparks which can start a fire.
SAFETY INSTRUCTIONS 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.
SAFETY INSTRUCTIONS Muffler • 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. • Maintain the correct raker clearance! Follow our instructions and use the recommended raker gauge. Too large a clearance increases the risk of kickback.
SAFETY INSTRUCTIONS Chain • Number of drive links. The number of drive links is determined by the length of the bar, the chain pitch and the number of teeth on the bar tip sprocket. • 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. The bar must be matched to the chain saw design. A chain is made up of a number of links, which are available in standard and low-kickback versions.
SAFETY INSTRUCTIONS Sharpening your chain and adjusting raker clearance ! 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. WARNING! The risk of kickback is increased with a badly sharpened 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 ! 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. Clean and lubricate if necessary.
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 How to avoid kickback ! 3 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. Most kickback accidents happen during limbing.
SAFETY INSTRUCTIONS 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. In this case the chain saw pulls itself towards the tree and the front edge of the chain saw body rests naturally on the trunk when cutting. Cutting on the pull stroke gives the operator better control over the chain saw and the position of the kickback zone. Before use: , 9 Follow the instructions on sharpening and maintaining your bar and chain.
SAFETY INSTRUCTIONS • • Observe your surroundings and make sure that there is no risk of people or animals coming into contact with the cutting equipment. Place the chain saw on the ground and hold the rear handle down with your right foot. Grasp the front handle firmly using your left hand. Make sure the chain saw is steady and the chain is not touching the ground or other objects. Then grasp the starter handle with your right hand and pull the starter cord.
SAFETY INSTRUCTIONS • • Take great care when removing small branches and avoid cutting bushes (i.e. cutting many small branches at the same time). Small branches can be grabbed by the chain and thrown back at you, causing serious injury. Make sure you can move and stand safely. Check the area around you for possible obstacles (roots, rocks, branches, ditches, etc.) in case you have to move suddenly. Take great care when working on sloping ground.
SAFETY INSTRUCTIONS In most cases you can avoid these problems by cutting in two stages; from the top and from the bottom. You need to support the object so that it will not trap the chain or split during cutting. ! WARNING! If the chain jams in the cut: stop the engine! Don’t try to pull the chain saw free. If you do you may be injured by the chain when the chain saw suddenly breaks free. Use a lever to open up the cut and free the chain saw.
SAFETY INSTRUCTIONS Tree felling technique ! WARNING! It takes a lot of experience to fell a tree. Inexperienced users of chain saws should not fell trees. Do not attempt any task that you feel unsure of! Safe distance The safe distance between a tree that is to be felled and anyone else working nearby is at least 21/2 tree lengths. Make sure that no-one else is in this ”risk zone” before or during felling.
SAFETY INSTRUCTIONS 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°. 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. The line where the two cuts meet is called the directional cut line. This line should be perfectly horizontal and at right angles (90°) to the chosen felling direction.
SAFETY INSTRUCTIONS Limbing Cutting trees and branches that are in tension Preparations: ! WARNING! Most kickback accidents happen during limbing! Pay close attention to the position of the kickback zone of the bar when you are limbing branches that are in tension! Make sure that you can stand and move about safely. Work on the left side of the trunk. Work as close as possible to the chain saw for maximum control. If possible, let the weight of the chain saw rest on the trunk.

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, 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 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. • Always mix the gasoline and oil in a clean container intended for fuel.
FUEL HANDLING 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. Always move the machine away from the refuelling area before starting. Clean the area around the fuel cap. Clean the fuel and chain oil tanks regularly.
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 Pull the front hand guard towards the front handle. The chain brake is now disengaged. Your saw is ready for use. Stopping Stop the engine by switching off the ignition.
MAINTENANCE Carburettor Fine adjustment Your Husqvarna product has been designed and manufactured to specifications that reduce harmful emissions. After the engine has used 8-10 tanks of fuel the engine will be run-in. To ensure that it continues to run at peak performance and to minimise harmful exhaust emissions after the runningin period, ask your dealer/service workshop (who will have a rev counter at their disposal) to adjust your carburettor.
MAINTENANCE Correctly adjusted carburettor Tensioning the recoil spring When the carburettor 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 Air filter • 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. Clean the air filter daily, or more often in demanding conditions. • Remove the air filter after taking off the air filter cover. When refitting make sure that the air filter seals tightly against the filter holder.
MAINTENANCE Adjustment of the oil pump ”Air Injection” centrifugal cleaning (350) Centrifugal cleaning means the following: All air to the carburettor passes through the starter. Dirt and dust is centrifuged out by the cooling fan. 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 CAUTION! If the special winterising kit has been fitted or any measures have been taken to increase the temperature these changes must be reversed before the machine is used in normal temperature conditions. Otherwise there is a risk of overheating, resulting in severe damage to the engine. Weekly maintenance 1 IMPORTANT! Any maintenance other than that described in this manual must be carried out by your servicing dealer (retailer).
