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. • Refuel and start the chain saw. See the instructions under the headings Fuel Handling and Starting and Stopping. • Do not use the chain saw until sufficient chain oil has reached the chain. See instructions under the heading Lubricating cutting equipment.
GENERAL SAFETY PRECAUTIONS Always use common sense It is not possible to cover every conceivable situation you can face when using a chain saw. Always exercise care and use your common sense. Avoid all situations which you consider to be beyond your capability. If you still feel uncertain about operating procedures after reading these instructions, you should consult an expert before continuing. Do not hesitate to contact your dealer or us if you have any questions about the use of the chain saw.
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. • • • To release the chain brake pull the front hand guard backwards, towards the front handle. • Kickback can be very sudden and violent. Most kickbacks are minor and do not always activate the chain brake. If this happens you should hold the chain saw firmly and not let go.
GENERAL SAFETY PRECAUTIONS of the front hand guard, the chain brake can only be activated by the inertia action. (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. This arrangement means that the throttle control is automatically locked at the idle setting. Will my hand always activate the chain brake during a kickback? No.
GENERAL SAFETY PRECAUTIONS Vibration damping system Muffler Your machine is equipped with a vibration damping system that is designed to reduce vibration and make operation easier. The muffler is designed to keep noise levels to a minimum and to direct exhaust fumes away from the user. ! The machine′s vibration damping system reduces the transfer of vibration between the engine unit/cutting equipment and the machine′s handle unit.
GENERAL SAFETY PRECAUTIONS • 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. Chain A chain is made up of a number of links, which are available in standard and low-kickback versions. IMPORTANT! No saw chain design eliminates the danger of kickback. ! • Maintain the correct depth gauge setting! Follow our instructions and use the recommended depth gauge clearance.
GENERAL SAFETY PRECAUTIONS • Chain oil hole and hole for chain tensioner. The bar must be matched to the chain saw design. When you sharpen a cutting tooth there are four important factors to remember. 1 Filing angle Chain • • • Chain pitch (inches) 2 Cutting angle 3 File position 4 Round file diameter Drive link width (mm/inches) Number of drive links. Sharpening your chain and adjusting depth gauge setting It is very difficult to sharpen a chain correctly without the right equipment.
GENERAL SAFETY PRECAUTIONS • Check that the chain is correctly tensioned. A slack chain will move sideways, making it more difficult to sharpen correctly. • 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 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 0.16 inch (4 mm) the chain is worn out and should be replaced.
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 Never use waste oil! Using waste oil can be dangerous to you and damage the machine and environment. 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.
GENERAL SAFETY PRECAUTIONS Needle bearing lubrication • 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. Both versions of sprockets 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.
ASSEMBLY Fitting the bar and chain ! should be tensioned until it does not sag from the underside of the bar. WARNING! Always wear gloves, when working with the chain. CS 2245 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. Hold up the bar tip and tighten the bar nuts with the combination spanner.
ASSEMBLY Fit the bar over the bar bolts. Place the bar in its rearmost position. Place the chain over the drive sprocket locate it in the groove on the bar. Begin on the top edge of the bar. Make sure that the edges of the cutting links are facing forward on the top edge of the bar. Fit the clutch cover and locate the chain adjuster pin in the hole in the bar. Check that the drive links of the chain fit correctly over the drive sprocket and that the chain is correctly located in the groove in the bar.
FUEL HANDLING Fuel Mixing ratio 1:50 (2%) for all engines. Note! The machine is equipped with a two-stroke engine and must always be run using a mixture of gasoline 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. Gasoline, litre WARNING! Always ensure there is adequate ventilation when handling fuel.
FUEL HANDLING Fueling ! • Move the machine at least 10 ft (3 m) from the refuelling point before starting it. • Never start the machine: 1 If you have spilled fuel or chain oil on the machine. Wipe off the spillage and allow remaining fuel to evaporate. 2 If you have spilled fuel on yourself or your clothes, change your clothes. Wash any part of your body that has come in contact with fuel. Use soap and water. 3 If the machine is leaking fuel.
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 CAUTION! Do not pull the starter cord all the way out and do not let go of the starter handle when the cord is fully extended. This can damage the machine. • Observe your surroundings and make sure that there is no risk of people or animals coming into contact with the cutting equipment. Note! Reactivate the chain brake by pushing the front hand guard back towards the front handle. The chain saw is now ready for use. • Always hold the saw with both hands.
WORKING TECHNIQUES Before use: Basic safety rules 1 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. , 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.
WORKING TECHNIQUES 6 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. 7 When you put the chain saw on the ground, lock the saw chain using the chain brake and ensure you have a constant view of the machine. Switch the engine off before leaving your chain saw for any length of time.
WORKING TECHNIQUES user. If the saw chain is jamming, the saw may be pushed back at you. Cutting with a pushing chain increases the risk of kickback. See instructions under the heading How to avoid kickback. Terms Cutting = General term for cutting through wood. Limbing = Cutting branches off a felled tree. Splitting = When the object you are cutting breaks off before the cut is complete.
WORKING TECHNIQUES The following instructions describe how to handle the common situations you are likely to encounter when using a chain saw. Turn the log and finish the cut from the opposite side. Limbing When limbing thick branches you should use the same approach as for cutting. Cut difficult branches piece by piece. 1 The log is supported at one end. There is a high risk that it will split. 2 3 Start by cutting from below (about 1/3 of the way through).
WORKING TECHNIQUES Felling direction Clearing the trunk and preparing your retreat The aim is to fell the tree in a position where you can limb and cross-cut the log as easily as possible. You want it to fall in a location where you can stand and move about safely. Delimb the stem up to shoulder height. It is safer to work from the top down and to have the tree between you and the saw. Once you have decided which way you want the tree to fall you must judge which way the tree would fall naturally.
WORKING TECHNIQUES Next make the bottom cut so that it finishes exactly at the end of the top cut. 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 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°.
WORKING TECHNIQUES Freeing a tree that has fallen badly necessary to reduce the tension and make the tree or branch break at the point of maximum tension. Freeing a ”trapped tree” It is very dangerous to remove a trapped tree and there is high accident risk. Never try to fell the tree that is trapped. Never work in the risk zone of the hanging trapped tree.
WORKING TECHNIQUES was being used when the kickback zone of the bar touched the object. Kickback only occurs if the kickback zone of the bar touches an object. Limbing ! WARNING! A majority of kickback accidents occur during limbing. Do not use the kickback zone of the guide bar. Be extremely cautious and avoid contacting the log, other limbs or objects with the nose of the guide bar. Be extremely cautious of limbs under tension.
MAINTENANCE General The user must only carry out the maintenance and service work described in this manual. More extensive work must be carried out by an authorised service workshop. Carburetor adjustment Your Jonsered product has been designed and manufactured to specifications that reduce harmful exhaust fumes. Checking, maintaining and servicing chain saw safety equipment Note! All servicing and repair work on the machine requires special training.
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. With the engine turned off, 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.
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 position (push the red button downwards). 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.
MAINTENANCE use a muffler if the spark arrestor screen is missing or defective. • Undo the bolt in the centre of the pulley and remove the drive disc (A), drive disc spring (B) and the pulley (C). Insert and secure a new starter cord in the starter pulley. Wind approx. 3 turns of the starter cord on the starter pulley. Fit the starter pulley so that the end of the recoil spring (D) hooks into the starter pulley. Now assemble the drive disc spring, drive disc and the bolt in the centre of the pulley.
MAINTENANCE Replacing the return and drive springs Air filter Recoil spring (A) The air filter must be regularly cleaned to remove dust and dirt in order to avoid: • • • Lift up the starter pulley. See instructions under the heading Changing a starter cord. Remember that the recoil spring is coiled under tension in the starter housing. Remove the cassette with the recoil spring from the starter. Lubricate the recoil spring with light oil. Fit the cassette with recoil spring in the starter.
MAINTENANCE Spark plug Needle bearing lubrication The spark plug condition is influenced by: The clutch drum has a needle bearing on the output shaft. This needle bearing must be lubricated regularly. • Incorrect carburetor adjustment. • An incorrect fuel mixture (too much or incorrect type of oil). • A dirty air filter. These factors cause deposits on the spark plug electrodes, which may result in operating problems and starting difficulties.
MAINTENANCE ”Turbo Air Cleaning” centrifugal cleaning Centrifugal cleaning means the following: All air to the carburetor passes through the starter. Dirt and dust is pushed out by the cooling fan. IMPORTANT! In order to maintain operation of the centrifugal cleaning system it must be regularly maintained. Clean the air intake to the starter, the fins on the flywheel, the space around the flywheel, inlet pipe and carburetor compartment.
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 0.024 inch (0.6 mm) remains at the most worn point.
