Category C = 50 hours, B = 125 hours, and A = 300 hours. Jonsered has a policy of continuous product development and therefore reserves the right to modify the design and appearance of products without prior notice.
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 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. Your chain saw is equipped with a chain brake that is designed to stop the chain immediately if you get a kickback. The chain brake reduces the risk of accidents, but only you can prevent them. Take care when using your saw and make sure the kickback zone of the bar never touches any object.
SAFETY INSTRUCTIONS it cannot affect the movement of the front hand guard, the chain brake can only be activated by the inertia of the counterweight. • The inertia activated chain brake is a valuable feature but there are certain factors to remember (see point above). Throttle lock The throttle lock 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).
SAFETY INSTRUCTIONS Muffler Regularly check that the brake band is at least 0.6 mm (0,024 inch) thick at its thinnest point. The muffler is designed to keep noise levels to a minimum and to direct exhaust fumes away from the user. Checking the front hand guard 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 Checking the brake trigger Place the chain saw on firm ground and start it. Make sure the chain does not touch the ground or any other object. See the instructions under the heading Start and stop. • Start the chain saw and apply full throttle. Release the throttle control and check that the chain stops and remains stationary. If the chain rotates when the throttle control is in the idle position you should check the carburetor idle adjustment.
SAFETY INSTRUCTIONS Stop switch General rules • Only use cutting equipment recommended by us! See the Technical data section. • 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. Never use a machine that has a faulty muffler. • Maintain the correct raker clearance! Follow our instructions and use the recommended raker gauge.
SAFETY INSTRUCTIONS Bar • Chain pitch (inches). The spacing between the drive links of the chain must match the spacing of the teeth on the bar tip sprocket and drive sprocket. • 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.
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 • File all the teeth to the same length. When the length of the cutting teeth is reduced to 4 mm (0.16") the chain is worn out and should be replaced. • Place the file over the part of the lip that protrudes through the gauge and file off the excess. The clearance is correct when you no longer feel any resistance as you draw the file over the gauge. General advice on setting raker clearance • When you sharpen the cutting teeth you reduce the raker clearance (=cutting depth).
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 Both versions have a needle bearing on the drive shaft, which has to be greased regularly (once a week). CAUTION! Use only high quality bearing grease or engine oil. • 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.
SAFETY INSTRUCTIONS 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. Do not let go of the handles! 3 Most kickback accidents happen during limbing.
SAFETY INSTRUCTIONS Unless the user resists this pushing force there is a risk that the chain saw will move so far backwards that only the kickback zone of the bar is in contact with the tree, which can lead to a kickback. • Never use any accessories other than those recommended in this manual. See instructions under the headings Cutting equipment and Technical data. ! WARNING! The risk of accident is increased if you use the wrong cutting equipment or a chain that is not sharpened correctly.
SAFETY INSTRUCTIONS • • • Never start the machine indoors. Exhaust fumes can be dangerous if inhaled. 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.
SAFETY INSTRUCTIONS Follow the instructions above, but do not use a chain saw in a situation where you cannot call for help in case of an accident. • Do not use the machine in bad weather, such as dense fog, heavy rain, strong wind, intense cold, etc. Working in bad weather is tiring and often brings added risks, such as icy ground, unpredictable felling direction, etc. • Take great care when removing small branches and avoid cutting bushes (i.e. cutting many small branches at the same time).
SAFETY INSTRUCTIONS 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. You need to support the object so that it will not trap the chain or split during cutting.
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 beyond your experience level! Safe distance The safe distance between a tree that is to be felled and anyone else working nearby is at least 2 1/2 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 ! General advice: 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. 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. The chain is correctly tensioned when it does not sag from the underside of the bar, but can still be turned easily by hand.
FUEL HANDLING Fuel Mixing ratio 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.
FUEL HANDLING Chain oil • The chain lubrication system is automatic and we recommend the use of special oil (chain oil) with good adhesion characteristics. Fueling ! 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 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 Carburetor adjustment Basic settings and running in Due to existing environmental and emissions legislation your chain saw is equipped with movement limiters on the carburetor adjuster screws. These limit the adjustment possibilities to a maximum of a 1/2 turn. 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 High speed jet H • 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.
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 carburetor adjustment. • Wrong fuel mixture (too much oil). • A dirty air filter.
MAINTENANCE Needle bearing lubrication Cooling system The clutch drum is fitted with one of the following drive sprockets: To keep the working temperature as low as possible the machine is equipped with a cooling system. • A Spur sprocket (the chain sprocket is welded on the drum) The cooling system consists of: • B Rim sprocket (replaceable) 1 Air intake on the starter. 2 Air guide plate. 3 Fins on the flywheel. 4 Cooling fins on the cylinder.
MAINTENANCE Heated handles Below you will find some general maintenance instructions.
