CONTENTS You will find the following labels on your machine: EPA I The Emissions Compliance Period referred to on the Emission Compliance label indicates the number of operating hours for which the engine has been shown to meet Federal emissions requirements. 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 • You can also use the chain brake as a temporary brake when you change position or if you put the chain saw down for a short time! Apart from the fact that a chain saw with a chain brake greatly reduces the risk of accidents 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.
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 front 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 minimize vibration and make operation easier.
SAFETY INSTRUCTIONS Muffler Checking the front hand guard The muffler is designed to keep noise levels to a minimum and to direct exhaust fumes away from the user. 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 Grasp the chain saw firmly, wrapping your fingers and thumbs around the handles. Chain catcher Check that the chain catcher is not damaged and is firmly attached to the body of the chain saw. 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.
SAFETY INSTRUCTIONS Muffler • 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. • Maintain the correct raker clearance! Follow our instructions and use the recommended raker gauge. Too large a clearance increases the risk of kickback.
SAFETY INSTRUCTIONS Chain • 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. The bar must be matched to the chain saw design. A chain is made up of a number of links, which are available in standard and low-kickback versions. None Standard Low-kickback Cutting link Drive link Side link Chain Combining these links in different ways gives different degrees of kickback reduction.
SAFETY INSTRUCTIONS • A sharp chain eats its way through the wood and produces long, thick cuttings. ! WARNING! The following faults will increase the risk of kickback considerably: File angle too large Cutting angle too small • The cutting part of the chain is called the cutting link and this consists of a cutting tooth (A) and the raker lip (B). The cutting depth is determined by the difference in height between the two.
SAFETY INSTRUCTIONS See the Technical data section to find the raker clearance for your particular chain. • On a low-kickback cutting link the front edge of the raker lip is rounded. It is very important that you maintain this radius or bevel when you adjust the raker clearance. Tensioning the chain ! WARNING! A slack chain may jump off and cause serious or even fatal injury. The more you use a chain the longer it becomes. It is therefore important to adjust the chain regularly to take up the slack.
SAFETY INSTRUCTIONS Lubricating cutting equipment ! • 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. WARNING! Poor lubrication of cutting equipment may cause the chain to snap, which could lead to serious, even fatal injuries.
SAFETY INSTRUCTIONS Checking wear on cutting equipment • 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. Check the chain daily for: • Visible cracks in rivets and links. • Whether the chain is stiff. • Whether rivets and links are badly worn.
SAFETY INSTRUCTIONS Kickback always occurs in the cutting plane of the bar. Normally the chain saw and bar are thrown backwards and upwards towards the user. However, the chain saw may move in a different direction depending on the way it was being used when the kickback zone of the bar touched the object. 4 Never use the chain saw above shoulder height and try not to cut with the tip of the bar. Never use the chain saw one-handed! 5 In order to keep control of your saw, always maintain a firm foothold.
SAFETY INSTRUCTIONS 8 Follow the instructions on sharpening and maintaining your bar and chain. When you replace the bar and chain use only combinations that are recommended by us. See instructions under the headings Cutting equipment and Technical data. ! WARNING! The risk of kickback is increased if you use the wrong cutting equipment or a chain that is not sharpened correctly.
SAFETY INSTRUCTIONS • 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. Then grasp the starter handle with your right hand and pull the starter cord. Never wrap the starter cord around your hand • Ensure the machine is cleaned and that a complete service is carried out before long-term storage.
SAFETY INSTRUCTIONS • • Make sure you can move and stand safely. Check the area around you for possible obstacles (roots, rocks, branches, ditches, etc.) in case you have to move suddenly. Take great care when working on sloping ground. Take the utmost care when cutting through branches or logs that are in tension. A log or branch that is in tension can suddenly spring back into its natural position before or after you cut it.
SAFETY INSTRUCTIONS 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. ! WARNING! If the chain jams in the cut: stop the engine! Don’t try to pull the chain saw free. If you do you may be injured by the chain when the chain saw suddenly breaks free. Use a lever to open up the cut and free the chain saw.
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 that you feel unsure of! Safe distance The safe distance between a tree that is to be felled and anyone else working nearby is at least 21/2 tree lengths. Make sure that no-one else is in this ”risk zone” before or during felling.
SAFETY INSTRUCTIONS 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. When the felling cut and directional cut are complete the tree should start to fall by itself or with the aid of a felling wedge or breaking bar. Felling cut The felling cut is made from the opposite side of the tree and it must be perfectly horizontal. Stand on the left side of the tree and cut on the pull stroke.
SAFETY INSTRUCTIONS Cutting the trunk into logs See instructions under the heading Basic cutting technique. 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 ! 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. 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 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. • Always mix the gasoline and oil in a clean container intended for fuel.
FUEL HANDLING Fuelling ! 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. Always move the machine away from the refuelling area before starting. Clean the area around the fuel cap. Clean the fuel and chain oil tanks regularly.
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 Carburettor Fine adjustment Your Jonsered product has been designed and manufactured to specifications that reduce harmful exhaust fumes. 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 centre of the pulley. Insert the starter cord through the hole in the starter housing and the starter handle. Make a secure knot in the end of the starter cord. CAUTION! There is an integrated speed governor in the ignition system that limits the maximum speed to 13600 rpm. The maximum speed will not exceed 13600 rpm when the high speed jet is adjusted (screwed in). When the speed governor is activated, you will get the same sound experience as when the chain saw 4-cycles.
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 carburettor 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 Winter use (CS 2171W) During cold weather and under powder snow conditions, operating problems can arise due to: On models with the model code W, both the front handle bar and the rear handle are equipped with electrical heating coils. These are supplied with electricity from a generator built into the chain saw. • Too low engine temperature. • Icing of the air filter and carburettor.
