GENERAL SAFETY PRECAUTIONS Before using a new chain saw Important • 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. You should only use the saw with the bar and chain combinations we recommend in the chapter Technical data.
GENERAL SAFETY PRECAUTIONS 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. • This movement activates a spring-loaded mechanism that tightens the brake band (C) around the engine drive system (D) (clutch drum). • The front hand guard is not designed solely to activate the chain brake.
GENERAL SAFETY PRECAUTIONS 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. when you grasp the handle) it releases the throttle control (B). When you release the handle the throttle control and the throttle lockout both move back to their original positions.
GENERAL SAFETY PRECAUTIONS chain saw, including the cutting equipment, is insulated from the handles by vibration damping units. requiring among other things the muffler must be equipped with an approved type of spark arrestor mesh. 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.
GENERAL SAFETY PRECAUTIONS gauge clearance. Too large a clearance increases the risk of kickback. a bar and chain combinations recommended by Jonsered. See instructions under the heading Technical Data for a list of replacement bar and chain combinations we recommend. Bar • • Keep the chain properly tensioned! If the chain is slack it is more likely to jump off and lead to increased wear on the bar, chain and drive sprocket.
GENERAL SAFETY PRECAUTIONS • Drive link width (mm/inches) • Number of drive links. Sharpening your chain and adjusting depth gauge setting General information on sharpening cutting teeth • Never use a blunt chain. When the chain is blunt you have to exert more pressure to force the bar through the wood and the chips will be very small. If the chain is very blunt it will produce wood powder and no chips or shavings.
GENERAL SAFETY PRECAUTIONS • acheive the correct depth gauge setting and bevel for the depth gauge. 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 over 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 (5/32") the chain is worn out and should be replaced. Place the depth gauge tool over the chain.
GENERAL SAFETY PRECAUTIONS • • Raise the tip of the bar and stretch the chain by tightening the chain tensioning screw using the combination spanner. Tighten the chain until it does not sag from the underside of the bar. Use the combination spanner to tighten the bar nuts while lifting the tip of the bar at the same time. Check that you can pull the chain round freely by hand and that it does not sag from the underside of the bar.
GENERAL SAFETY PRECAUTIONS • 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. week). CAUTION! Use a high-quality bearing grease or engine oil.
GENERAL SAFETY PRECAUTIONS • 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. ! 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.
ASSEMBLY Fitting the bar and chain ! correctly located in the groove in the bar. Tighten the bar nuts finger tight. 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. 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.
FUEL HANDLING Fuel Petrol, litre Note! The machine is equipped with a two-stroke engine and must always been run using a mixture of petrol and two-stroke 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. ! WARNING! Always ensure there is adequate ventilation when handling fuel.
FUEL HANDLING • In temperatures below 0°C (32°F) some oils become too viscous. This can overload the oil pump and result in damage to the oil pump components. • Contact your service agent when choosing chain oil. • Move the machine at least 3 m from the refuelling point before starting it. Fuelling ! WARNING! Taking the following precautions, will lessen the risk of fire: Do not smoke and do not place any hot objects in the vicinity of fuel.
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: 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 starts, quickly apply full throttle; the throttle start lock will automatically disengage. • Never start the machine indoors. Exhaust fumes can be dangerous if inhaled. As the chain brake is still engaged the speed of the engine must be set to idling as soon as possible, this is achieved by quickly disengaging the throttle lock. This prevents unnecessary wear to the clutch, clutch drum and brake band.
WORKING TECHNIQUES Before use: • 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 lockout works correctly and is not damaged. 4 Check that the stop switch works correctly and is not damaged.
WORKING TECHNIQUES lose control. Both situations can cause serious personal injury. 6 7 Lack of concentration can lead to kickback if the kickback zone of the bar accidentally touches a branch, nearby tree or some other object. 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. Have control over the workpiece.
WORKING TECHNIQUES ladder, in a tree or where you do not have firm ground to stand on. Basic cutting technique ! WARNING! Never use a chain saw by holding it with one hand. A chain saw is not safely controlled with one hand. Always have a secure, firm grip around the handles with both hands. General 6 Always use a fast cutting speed, i.e. full throttle. 7 Take great care when you cut with the top edge of the bar, i.e. when cutting from the underside of the object.
WORKING TECHNIQUES 5 Do the conditions and surrounding terrain affect how safely you can stand and move about? risk that the chain will touch the ground when you finish the cut. Two factors decide whether the chain will jam or the object that you are cutting will split: the first is how the object is supported before and after cutting, and the second is whether it is in tension. In most cases you can avoid these problems by cutting in two stages; from the top and from the bottom.
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 that you feel unsure of! 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 ! WARNING! Unless you have special training we advise you not to fell trees with a diameter larger than the bar length of your saw! Set the spike bumper (if one is fitted) just behind the felling hinge. Use full throttle and advance the chain/bar slowly into the tree. Make sure the tree does not start to move in the opposite direction to your intended felling direction. Drive a wedge or breaking bar into the cut as soon as it is deep enough. Felling is done using three cuts.
WORKING TECHNIQUES 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. Cutting trees and branches that are in tension Preparations: Work out which side is in tension and where the point of maximum tension is (i.e. where it would break if it was bent even more).
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 Carburettor adjustment Function, Basic settings, Fine adjustment The carburettor can be designed in different ways, depending on existing environmental and emissions legislation. Some chain saws are equipped with movement limiters on the carburettor’s adjuster screws. These limit the adjustment possibilities to a maximum of a 1/2 turn.
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. Fine adjustment When the machine has been ”run-in” the carburettor should be finely adjusted. The fine adjustment should be carried out by a qualified person. First adjust the L-jet, then the idling screw T and then the H-jet.
MAINTENANCE Function, Basic settings, Fine adjustment WARNING! Do not start the chain saw unless the bar, chain and clutch cover (chain brake) are fitted, otherwise the clutch may come loose and cause personal injury. ! carried out by a qualified person. First adjust the L-jet, then the idling screw T and then the H-jet. Conditions • Before any adjustments are made the air filter should be clean and the cylinder cover fitted.
MAINTENANCE High speed jet H • The high speed jet H influences the power and engine speed of the machine. If the high speed jet is set too rich (H-jet screwed in too far) the machine will over-rev and this will damage the engine. Run the machine at full throttle for about 10 seconds. Then turn the H-jet 1/4 turn anti-clockwise. Run the machine at full throttle for another 10 seconds or so and listen to the difference in the fast idle speed.
MAINTENANCE Checking the inertia brake release 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. Place the chain saw, with the engine switched off, on a stump or other stable surface. Release the front handle and let the saw fall by its own weight, rotating around the rear handle towards the stump.
MAINTENANCE Chain catcher Stop switch Check that the chain catcher is not damaged and is firmly attached to the body of the chain saw. 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. The muffler is designed to reduce the noise level and to direct the exhaust gases away from the operator. The exhaust gases are hot and can contain sparks, which may cause fire if directed against dry and combustible material. • 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.
MAINTENANCE Remember that the recoil spring is coiled under tension in the starter housing. • Remove the recoil spring from inside the pulley by tapping the pulley lightly with its inside face downwards against a work bench or the like. If the spring pops out during fitting, wind it up again, working from the outside in towards centre. • Lubricate the recoil spring with light oil. Fit the pulley and tension the recoil spring. The filter can be cleaned more thoroughly by washing it in water and detergent.
MAINTENANCE Lubricating the bar tip sprocket ! WARNING! The engine must not be running when making adjustments. Cooling system Lubricate the bar tip sprocket each time you refuel. Use the special grease gun and a good quality bearing grease. To keep the working temperature as low as possible the machine is equipped with a cooling system. The cooling system consists of: Needle bearing lubrication 1 Air intake on the starter. 2 Air guide plate. 3 Fins on the flywheel.
MAINTENANCE • Too low engine temperature. • Icing of the air filter and carburettor. Special measures are therefore often required: • Partly mask the air inlet on the starter to increase the working temperature of the engine. Temperature -5°°C or colder: 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.
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.
