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. 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 • This movement activates a spring-loaded mechanism that tightens the brake band (C) around the engine drive system (D) (clutch drum). • The way the chain brake is activated, either manually or automatically by the inertia release mechanism, depends on the force of the kickback and the position of the chain saw in relation to the object that the kickback zone of the bar strikes.
GENERAL SAFETY PRECAUTIONS Will my inetria activated chain brake always activate during kickback in the event of a kickback? No. First your brake must be in working order. Second the kickback must be strong enough to activate the chain brake. If the chain brake is too sensitive it would activate all the time which would be a nuisance. Will my chain brake always protect me from injury in the event of a kickback? No. First, the chain brake must be in working order to provide the intended protection.
GENERAL SAFETY PRECAUTIONS Muffler • 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. • 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 Bar • Length (inches/cm) Sharpening your chain and adjusting depth gauge setting General information on sharpening cutting teeth • • Number of teeth on bar tip sprocket (T). • • 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 ! WARNING! Departure from the sharpening instructions considerably increases the risk of kickback. Adjustment of depth gauge setting Sharpening cutting teeth • To sharpen cutting teeth you will need a round file and a file gauge. See instructions under the heading Technical data for information on the size of file and gauge that are recommended for the chain fitted to your chain saw. • • • Check that the chain is correctly tensioned.
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. • The saw chain oil tank and the fuel tank are designed so that the fuel runs out before the saw chain oil.
GENERAL SAFETY PRECAUTIONS Chain drive sprocket • 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. The clutch drum is fitted with one of the following drive sprockets: A Spur sprocket (the chain sprocket is welded on the drum) B Rim sprocket (replaceable) Regularly check the degree of wear on the drive sprocket. Replace if wear is excessive.
ASSEMBLY Fitting the bar and chain ! 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. 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 ratio Note! The machine is equipped with a two-stroke engine and must always be run using a mixture of gasoline 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. ! 1:50 (2%) for all engines. Gasoline, litre WARNING! Always ensure there is adequate ventilation when handling fuel.
FUEL HANDLING • • In temperatures below 32°F (0°C) some oils become too viscous. This can overload the oil pump and result in damage to the oil pump components. Fuel safety • Never refuel the machine while the engine is running. Contact your service agent when choosing chain oil. • Make sure there is plenty of ventilation when refuelling or mixing fuel (gasoline and 2-stroke oil). • Move the machine at least 10 ft (3 m) from the refuelling point before starting it.
STARTING AND STOPPING Starting and stopping ! 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. Make sure you have a secure footing and that the chain cannot touch anything.
STARTING AND STOPPING • Never start a chain saw unless the bar, chain and all covers are fitted correctly. See instructions under the heading Assembly. Without a bar and chain attached to the chain saw the clutch can come loose and cause serious injury. • The chain brake should be activated when starting. Se instructions under the heading Start and stop. Do not drop start. This method is very dangerous because you may lose control of the saw. • Never start the machine indoors.
WORKING TECHNIQUES Before use: 1 Basic safety rules 1 • 3 2 4 6 1 2 3 4 5 6 7 8 9 • 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. 8 Check that the chain brake works correctly and is not damaged. Check that the throttle lockout works correctly and is not damaged. Check that the stop switch works correctly and is not damaged.
WORKING TECHNIQUES 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. 8 9 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.
WORKING TECHNIQUES Cutting with the bottom edge of the bar, i.e. from the top of the object downwards, is known as cutting with a pulling chain. 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 with a pulling chain gives the operator better control over the chain saw and the position of the kickback zone.
WORKING TECHNIQUES The log is supported at one end. There is a high risk that it will split. Start by cutting from below (about 1/3 of the way through). - Finish by cutting from above so that the two cuts meet. Safe distance During tree maintenance work above ground level, the working area must always be secured and marked out with signs, tape or the like. The safe distance between the top of the tree that is to be felled and the nearest workplace must be at least 2 1/2 times the height of the tree.
WORKING TECHNIQUES Felling 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. Use full throttle and bring the bar and chain slowly into the tree. Make sure the tree does not start to move in the opposite direction to your intended felling direction.
WORKING TECHNIQUES ! WARNING! Unless you have special training we advise you not to fell trees with a diameter larger than the bar length of your saw! How to avoid kickback ! Limbing ! 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.
MAINTENANCE General Basic settings and running in 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). 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.
MAINTENANCE Correctly adjusted carburetor When the carburetor 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 Chain catcher Regularly check that the muffler is securely attached to the machine. Check that the chain catcher is not damaged and is firmly attached to the body of the chain saw. Vibration damping system Regularly check the vibration damping units for cracks or deformation. Some mufflers are equipped with a special spark arrestor screen. If your machine has this type of muffler, you should clean the screen at least once a week. This is best done with a wire brush.
MAINTENANCE • Pull out the cord approx. 30 cm (12 inches) 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. Fit the screw in the center of the pulley.
MAINTENANCE An air filter that has been in use for a long time cannot be cleaned completely. The filter must therefore be replaced with a new one at regular intervals. A damaged air filter must always be replaced. A JONSERED chain saw can be equipped with different types of air filter according to working conditions, weather, season, etc. Contact your dealer for advice. Adjustment of the oil pump The oil pump is adjustable.
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 0.024 inch (0.6 mm) remains at the most worn point.
