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 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 • 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 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 minimise vibration and make operation easier.
SAFETY INSTRUCTIONS Muffler The muffler is designed to keep noise levels to a minimum and to direct exhaust fumes away from the user. Checking, maintaining and servicing the machine′s safety equipment ! ! WARNING! The exhaust fumes from the engine are hot and may contain sparks which can start a fire. Never start the machine indoors or near combustible material! WARNING! All servicing and repair work on the machine requires special training. This is especially true of the machine′s safety equipment.
SAFETY INSTRUCTIONS Checking the inertia brake release Throttle lock 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. • Make sure the throttle control is locked at the idle setting when the throttle lock is released. • Press the throttle lock and make sure it returns to its original position when you release it.
SAFETY INSTRUCTIONS Vibration damping system Never use a muffler if the spark arrestor mesh is missing or defective. ! Regularly check the vibration damping units for cracks or deformation. Make sure the vibration damping units are securely attached to the engine unit and handle unit. WARNING! Never use a machine with faulty safety equipment. The machine’s safety equipment must be checked and maintained as described in this section.
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.
SAFETY INSTRUCTIONS • • Number of drive links. Level of kickback reduction. The level of kickback reduction offered by a chain is only indicated by its model number. See the Technical data section to find the model numbers of chains that are recommended for use with your model of chain saw. When you sharpen a cutting tooth there are five important factors to remember.
SAFETY INSTRUCTIONS Sharpening cutting teeth • We recommend that you use our raker gauge to achieve the correct clearance and bevel on the raker lip. To sharpen cutting teeth you will need a round file and a file gauge. See the Technical data section for information on the size of file and gauge that are recommended for the chain fitted to your chain saw.
SAFETY INSTRUCTIONS Tension the chain as tightly as possible, but not so tight that you cannot pull it round freely by hand. Never use waste oil! This is dangerous for yourself, the machine and the environment. Filling with chain oil • • Undo the bar nuts that hold the clutch cover/chain brake. Use the combination spanner. Then tighten the bar nuts by hand as tight as you can. • All our chain saws have an automatic chain lubrication system. On some models the oil flow is also adjustable.
SAFETY INSTRUCTIONS • 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. We recommend you compare the existing chain with a new chain to decide how badly the existing chain is worn. When the length of the cutting teeth has worn down to only 4 mm the chain must be replaced.
SAFETY INSTRUCTIONS ! WARNING! Most chain saw accidents happen when the chain touches the operator. Kickback only occurs if the kickback zone of the bar touches an object. 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. See instructions under the headings Personal protective equipment, How to avoid kickback, Cutting equipment and General working instructions.
SAFETY INSTRUCTIONS 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. 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. This is known as cutting on the push stroke. The chain tries to push the chain saw back towards the user.
SAFETY INSTRUCTIONS 5 Check that all handles are free from oil. 6 Check that the anti vibration system works and is not damaged. 7 Check that the muffler is securely attached and not damaged. 8 Check that all parts of the chain saw are tightened correctly and that they are not damaged or missing. 9 Check that the chain catcher is in place and not damaged. objects. Then grasp the starter handle with your right hand and pull the starter cord. Never twist the starter cord around your hand.
SAFETY INSTRUCTIONS Transport and storage • Always store the chain saw and fuel so that there is no risk of leakages or fumes coming into contact with sparks or naked flames from electrical equipment, electric motors, relays/switches, boilers and the like. • Always store fuel in an approved container designed for that purpose. • For longer periods of storage or for transport of the chain saw, the fuel and chain oil tanks should be emptied.
SAFETY INSTRUCTIONS • 3 Make sure the chain will not strike the ground or any other object during or after cutting. 4 Is there a risk of kickback? 5 Do the conditions and surrounding terrain affect how safely you can stand and move about? Never put a chain saw down while the engine is running unless you have it in clear view and the chain brake is on. Switch the engine off before leaving your chain saw for any length of time.
SAFETY INSTRUCTIONS If it is possible (can you turn the log?) stop cutting about 2/3 of the way through the log. Limbing When limbing thick branches you should use the same approach as for cutting. Cut difficult branches piece by piece. 1 2 3 Turn the log and finish the cut from the opposite side. Tree felling technique The log is supported at one end. There is a high risk that it will split. ! WARNING! It takes a lot of experience to fell a tree.
SAFETY INSTRUCTIONS Several factors affect this: Felling Lean of the tree Wind direction 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. Arrangement of branches Directional cuts Weight of snow To make the directional cuts you begin with the top cut.
SAFETY INSTRUCTIONS opposite direction to your intended felling direction. Drive a wedge or breaking bar into the cut as soon as it is deep enough. Finish the felling cut parallel with the directional cut line so that the distance between them is at least 1/10 of the trunk diameter. The uncut section of the trunk is called the felling hinge. There are methods for felling trees with a diameter larger than the bar length.
SAFETY INSTRUCTIONS Freeing a tree that has fallen badly Freeing a ”trapped tree” It is very dangerous to remove a trapped tree and there is high accident risk. The safest method is to use a winch. • Tractor-mounted • Portable 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).

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. Check that the chain brake is in disengaged position by moving the hand guard towards the front handle. When fitting a new chain, the chain tension has to be checked frequently until the chain is run-in.
FUEL HANDLING Fuel Mixing 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. • Always mix the petrol and oil in a clean container intended for fuel.
FUEL HANDLING Chain oil • Fuelling The chain lubrication system is automatic and we recommend the use of special oil (chain oil) with good adhesion characteristics. ! 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. Use the same procedure as for starting a cold engine but without setting the choke control in the choke position. The correct choke/start throttle setting is obtained by moving the choke control to the choke position and then pushing it in again.
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 Your Jonsered product has been designed and manufactured to specifications that reduce harmful exhaust fumes. The engine will be run in after it has used 8-10 tanks of fuel. To ensure that the engine runs at peak performance and produces as little harmful exhaust fumes as possible after the running-in period, ask your dealer/service workshop (which has a rev counter for this purpose) to adjust your carburettor.
MAINTENANCE Fine adjustment of the idle speed T Starter Adjust the idle speed with the T-screw. If it is necessary to readjust, turn the T-screw clockwise while the engine is running, until the chain starts to rotate. Then turn anti-clockwise until the chain stops. When the idle speed is correctly adjusted the engine should run smoothly in every position and the engine speed should be safely below the speed at which the chain starts to rotate.
MAINTENANCE Tensioning the recoil spring • Hook the starter cord in the notch in the pulley and turn the starter pulley about 2 turns clockwise. CAUTION! Check that the pulley can be turned at least a further 1/2 turn when the starter cord is pulled all the way out. 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 Muffler Adjustment of the oil pump 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. 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 Centrifugal cleaning “Turbo” Temperature 0°°C or colder: 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 cylinder cover is designed so it can be adjusted for running in cold weather. Twist the winter flap so that preheated air from the cylinder can pass into the carburettor space preventing icing of the air filter, etc.
