Chain saws - Jonsered CS 2159 CWH
http://www.tilton.usa.jonsered.com/node326.aspx?pid=26
A power pack for the professional lumberjack with strict requirements for power, control and design. With its 60 cc of raw power and a highly competitive power-to-weight ratio, this saw is just as good for felling really big trees as it is for limbing and cross-cutting. This is Jonsereds first saw that has a carburettor with built-in fuel compensation. This means that the fuel-air mixture is kept constant, so that the power remains unchanged over time. Together with turbo air cleaning, this keeps the power high while reducing filter wear, emissions and fuel consumption. The machine also has a magnesium crankcase, side-mounted chain tensioner and a catalytic converter which decreases emissions without affecting power. The CWH model has heating in the handles and the carburettor.

GENERAL SAFETY PRECAUTIONS
Before using a new chain saw
Please read this manual carefully. Check that the cutting equipment is correctly tted 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 sufcient chain oil has reached the chain. See instructions under the heading Lubricating cutting equipment. Long-term exposure to noise can result in permanent hearing impairment. So always use approved hearing protection.

Important

IMPORTANT! This chain saw for forest service is designed for forest work such as felling, delimbing and cutting. You should only use the saw with the bar and chain combinations we recommend in the chapter Technical data. Never use the machine if you are fatigued, while under the inuence of alcohol or drugs, medication or anything that could affect your vision, alertness, coordination or judgement. Wear personal protective equipment. See instructions under the heading Personal protective equipment. Do not modify this product or use it if it appears to have been modied by others. Never use a machine that is faulty. Carry out the checks, maintenance and service instructions described in this manual. Some maintenance and service measures must be carried out by trained and qualied specialists. See instructions under the heading Maintenance. Never use any accessories other than those recommended in this manual. See instructions under the headings Cutting equipment and Technical data. CAUTION! Always wear protective glasses or a face visor to reduce the risk of injury from thrown objects. A chain saw is capable of throwing objects, such as wood chips, small pieces of wood, etc, at great force. This can result in serious injury, especially to the eyes. WARNING! Running an engine in a conned or badly ventilated area can result in death due to asphyxiation or carbon monoxide poisoning. WARNING! Faulty cutting equipment or the wrong combination of bar and saw chain increases the risk of kickback! Only use the bar/saw chain combinations we recommend, and follow the ling instructions. See instructions under the heading Technical data.

Chain catcher

The chain catcher is designed to catch the chain if it snaps or jumps off. This should not happen if the chain is properly tensioned (see instructions under the heading Assembly) and if the bar and chain are properly serviced and maintained (see instructions under the heading General working instructions).
Will my inertia activated chain brake always activate during kickback in the event of a kickback?
No. First your brake must be in working order. Testing the brake is simple, see instructions under the heading Checking, maintaining and servicing chain saw safety equipment. We recommend you do before you begin each work session. 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.

Right hand guard

Apart from protecting your hand if the chain jumps or snaps, the right hand guard stops branches and twigs from interfering with your grip on the rear handle.
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. Second, it must be activated during the kickback as described above to stop the saw chain. Third, the chain brake may be activated but if the bar is too close to you the brake might not have enough time to slow down and stop the chain before the chain saw hits you. Only you and proper working technique can eliminate kickback and its danger.

Vibration damping system

Your machine is equipped with a vibration damping system that is designed to minimize vibration and make operation easier.

Throttle lockout

The throttle lockout 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
The machines vibration damping system reduces the transfer of vibration between the engine unit/cutting equipment and the machines handle unit. The body of the

English 9

chain saw, including the cutting equipment, is insulated from the handles by vibration damping units. requiring among other things the mufer must be equipped with an approved type of spark arrestor mesh.
Cutting hardwoods (most broadleaf trees) creates more vibration than cutting softwoods (most conifers). Cutting with cutting equipment that is blunt or faulty (wrong type or badly sharpened) will increase the vibration level.

Visible cracks in rivets and links. Whether the chain is stiff. Whether rivets and links are badly worn.
Replace the saw chain if it exhibits any of the points above. 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. Bar
Check regularly: Whether there are burrs on the edges of the bar. Remove these with a le if necessary.
Whether the groove in the bar has become badly worn. Replace the bar if necessary.

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.
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.
Remove the bar nuts and remove the clutch cover (chain brake). Take off the transportation ring (A).
When tting a new chain, the chain tension has to be checked frequently until the chain is run-in. Check the chain tension regularly. A correctly tensioned chain ensures good cutting performance and long life.
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.

Fitting a spike bumper

To t a spike bumper contact your service agent.
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 t correctly over the drive sprocket and that the chain is correctly located in the groove in the bar. Tighten the bar nuts nger tight.
Tension the chain by turning the chain tensioning screw clockwise using the combination spanner. The chain 16 English

For best results and performance use JONSERED two-stroke engine oil, which is specially formulated for our air-cooled two-stroke engines. Never use two-stroke oil intended for water-cooled engines, sometimes referred to as outboard oil (rated TCW). Never use oil intended for four-stroke engines. A poor oil quality and/or too high oil/fuel ratio may jeopardise function and decrease the life time of catalytic converters. Never use waste oil. This results in damage to the oil pump, the bar and the chain. It is important to use oil of the right grade (suitable viscosity range) to suit the air temperature. In temperatures below 0C (32F) some oils become too viscous. This can overload the oil pump and result in damage to the oil pump components. Contact your service agent when choosing chain oil. English 17

Fuelling

Move the machine at least 3 m from the refuelling point before starting it.
WARNING! Taking the following precautions, will lessen the risk of re: Do not smoke and do not place any hot objects in the vicinity of fuel. Always stop the engine and let it cool for a few minutes 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. Never start the machine: If you have spilt fuel or chain oil on the machine. Wipe off the spillage and allow remaining fuel to evaporate. If you have spilt 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. If the machine is leaking fuel. Check regularly for leaks from the fuel cap and fuel lines.
Clean the area around the fuel cap. Clean the fuel and chain oil tanks regularly. The fuel lter must be replaced at least once a year. Contamination in the tanks causes malfunction. Make sure the fuel is well mixed by shaking the container before refuelling. The capacities of the chain oil tank and fuel tank are carefully matched. You should therefore always ll the chain oil tank and fuel tank at the same time.

WARNING! Never use a machine with visible damage to the spark plug guard and ignition cable. A risk of sparking arises, which can cause a re.

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 ames 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. Ask where you can dispose of waste fuel and chain oil at your local petrol station. The bar guard must always be tted to the cutting attachment when the machine is being transported or in storage, in order to prevent accident contact with the sharp chain. Even a non-moving chain can cause serious cuts to yourself or persons you bump into with an exposed chain. Secure the machine during transport.
WARNING! Fuel and fuel vapour are highly ammable. Take care when handling fuel and chain oil. Be aware of the risks of re, explosion and those associated with inhalation.

Fuel safety

Never refuel the machine while the engine is running. Make sure there is plenty of ventilation when refuelling or mixing fuel (petrol and 2-stroke oil).

Long-term storage

Empty the fuel/oil tanks in a well ventilated area. Store the fuel in approved cans in a safe place. Fit the bar guard. Clean the machine. See instructions under the heading Maintenance schedule. Ensure the machine is cleaned and that a complete service is carried out before long-term storage.

18 English

STARTING AND STOPPING

Starting and stopping

If the machine is tted with a decompression valve (A): Press the valve to reduce the pressure in the cylinder and make starting easier. You should always use the decompression valve when starting the machine. Once the machine has started the valve will automatically return to its original setting.
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 tted correctly. Otherwise the clutch can come loose and cause personal injuries. Place the machine on rm 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.

Never start a chain saw unless the bar, chain and all covers are tted 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.

Stopping

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.
The engine is stopped by pushing the stop switch to the stop position.
Never start the machine indoors. Exhaust fumes can be dangerous if inhaled.

WORKING TECHNIQUES

Before use:

To make sure that none of the above might come within reach of your saw or be injured by falling trees.
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. 4 Check that the stop switch works correctly and is not damaged. 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 mufer 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. 10 Check the chain tension.
CAUTION! 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. 2 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). Small branches can be grabbed by the chain and thrown back at you, causing serious injury.
General working instructions
IMPORTANT! This section describes basic safety rules for using a chain saw. This information is never a substitute for professional skills and experience. If you get into a situation where you feel unsafe, stop and seek expert advice. Contact your chain saw dealer, service agent or an experienced chain saw user. Do not attempt any task that you feel unsure of! Before using a chain saw you must understand the effects of kickback and how to avoid them. See instructions under the heading How to avoid kickback. Before using a chain saw you must understand the difference between cutting with the top and bottom edges of the bar. See instructions under the headings How to avoid kickback and Machines safety equipment. Wear personal protective equipment. See instructions under the heading Personal protective equipment.

Always use a fast cutting speed, i.e. full throttle. 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. If

22 English

the saw chain is jamming, the saw may be pushed back at you. 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. There are ve important factors you should consider before making a cut: 8 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 will lead to a kickback. 1 Make sure the cutting equipment will not jam in the cut.
Make sure the object you are cutting will not split.
Cutting with the bottom edge of the bar, i.e. from the top of the object downwards, is known as cutting on the pull stroke. 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 on the pull stroke gives the operator better control over the chain saw and the position of the kickback zone.
Make sure the chain will not strike the ground or any other object during or after cutting.
Is there a risk of kickback?
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.
Do the conditions and surrounding terrain affect how safely you can stand and move about?

Basic cutting technique

WARNING! Never use a chain saw by holding it with one hand. A chain saw is not safely controlled with one hand. Always have a secure, rm grip around the handles with both hands.
Two factors decide whether the chain will jam or the object that you are cutting will split: the rst 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. IMPORTANT! If the chain jams in the cut: stop the engine! Dont 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. The following instructions describe how to handle the commonest situations you are likely to encounter when using a chain saw.

General Always use full throttle when cutting! Reduce the speed to idle after every cut (running the engine for too long at full throttle without any load, i.e. without any resistance from the chain during cutting, can lead to serious engine damage). Cutting from above = Cutting on the pull stroke. Cutting from below = Cutting on the push stroke. Cutting on the push stroke increases the risk of kickback. See instructions under the heading How to avoid kickback.

English 23

Limbing When limbing thick branches you should use the same approach as for cutting. Cut difcult branches piece by piece. Turn the log and nish the cut from the opposite side.
The log is supported at one end. There is a high risk that it will split.

Cutting

Start by cutting from below (about 1/3 of the way through). Finish by cutting from above so that the two cuts meet. WARNING! Never attempt to cut logs while they are in a pile or when a couple of logs are lying together. Such procedures drastically increase the risk of kickback which can result in a serious or fatal injury.
If you have a pile of logs, each log you attempt to cut should be removed from the pile, placed on a saw horse or runners and cut individually. Remove the cut pieces from the cutting area. By leaving them in the cutting area, you increase the risk for inadvertently getting a kickback, as well as increasing the risk of losing your balance while working.
The log is supported at both ends. There is a high risk that the chain will jam.
Start by cutting from above (about 1/3 of the way through). Finish by cutting from below so that the two cuts meet.
The log is lying on the ground. There is little risk of the chain jamming or the object splitting. However there is a risk that the chain will touch the ground when you nish the cut.

Tree felling technique

IMPORTANT! 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
Cut all the way through the log from above. Avoid letting the chain touch the ground as you nish the cut. Maintain full throttle but be prepared for what might happen.
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.
If it is possible (can you turn the log?) stop cutting about 2/3 of the way through the log.

24 English

Felling direction 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. Once you have decided which way you want the tree to fall you must judge which way the tree would fall naturally. Several factors affect this: Lean of the tree Bend Wind direction Arrangement of branches Weight of snow Obstacles within the reach of the tree: for example, other trees, power lines, roads and buildings. Look for signs of damage and rot in the stem, this makes it more probably that the tree will break and start to fall before you expect it to. Remove any undergrowth from the base of the tree and check the area for obstacles (stones, branches, holes, etc.) so that you have a clear path of retreat when the tree starts to fall. Your path of retreat should be roughly 135 degrees away from the intended felling direction. Clearing the trunk and preparing your retreat 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.
You may nd you are forced to let the tree fall in its natural direction because it is impossible or dangerous to try to make it fall in the direction you rst intended. Another very important factor, which does not affect the felling direction but does affect your safety, is to make sure the tree has no damaged or dead branches that might break off and hit you during felling. The main point to avoid is letting the tree fall onto another tree. It is very dangerous to remove a trapped tree and there is high accident risk. See instructions under the heading Freeing a tree that has fallen badly.
Danger zone Retreat path Felling direction

Felling

WARNING! Unless you have special training we advise you not to fell trees with a diameter larger than the bar length of your saw!
Felling is done using three cuts. First you make the directional cuts, which consist of the top cut and the bottom cut, then you nish with the felling cut. By placing these cuts correctly you can control the felling direction very accurately. Directional cuts To make the directional cut you begin with the top cut. Aim using to the saws felling direction mark (1) toward a goal further forward in the terrain, where you would like the tree to fall (2). Stand on the right-hand side of the tree, behind the saw, and cut with a pull stroke.
IMPORTANT! During critical felling operations, hearing protectors should be lifted immediately when sawing is completed so that sounds and warning signals can be heard.

English 25

Next make the bottom cut so that it nishes exactly at the end of the top cut. The felling hinge controls the direction that the tree falls in.

Never cut straight through a tree or branch that is in tension! The safest method is to use a winch. Tractor-mounted If you must cut across tree/limb, make two to three cuts, one inch apart, one to two inches deep.

Portable

Continue to cut deeper until tree/limb bends and tension is released.
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). Cut tree/limb from outside the bend, after tension has been released.
Decide which is the safest way to release the tension and whether you are able to do it safely. In complicated situations the only safe method is to put aside your chain saw and use a winch.

English 27

How to avoid kickback
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. They can spring back toward you and cause loss of control resulting in injury.
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.

What is kickback?

The word kickback is used to describe the sudden reaction that causes the chain saw and bar to jump off an object when the upper quadrant of the tip of the bar, known as the kickback zone, touches an object.
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.
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.

Regularly check that the mufer is securely attached to the machine.
Regularly check the vibration damping units for cracks or deformation. Some mufers are equipped with a special spark arrestor mesh. If your machine has this type of mufer, you should clean the mesh at least once a week. This is best done with a wire brush. A blocked mesh will cause the engine to overheat and may lead to serious damage. Note! The mesh must be replaced if it is damaged. If the mesh is blocked the machine will overheat and this will cause damage to the cylinder and piston. Never use a machine with a mufer that is in poor condition. Never use a mufer if the spark arrestor mesh is missing or defective.
Make sure the vibration damping units are securely attached to the engine unit and handle unit.

32 English

The mufer 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 re if directed against dry and combustible material. A mufer equipped with a catalytic converter signicantly reduces the amount of hydrocarbons (HC), nitrogen oxides (NO) and aldehydes in the exhaust fumes. Carbon monoxide (CO), which is poisonous and odourless, is not however reduced! Consequently, never work in an enclosed or badly ventilated area. Good air circulation should always prevail when working in snowy hollows, ravines or in conned conditions. through the hole in the starter housing and the starter handle. Make a secure knot in the end of the starter cord.

Starter

WARNING! When the recoil spring is wound up in the starter housing it is under tension and can, if handled carelessly, pop out and cause personal injury. Care must be exercised when replacing the return spring or the starter cord. Wear protective glasses and protective gloves.
Tensioning the recoil spring
Hook the starter cord in the notch in the pulley and turn the starter pulley about 2 turns clockwise. Note! Check that the pulley can be turned at least a further 1/2 turn when the starter cord is pulled all the way out.
Changing a broken or worn starter cord
Loosen the screws that hold the starter against the crankcase and remove the starter.
Changing a broken recoil spring
Pull out the cord approx. 30 cm and hook it into the notch in the rim of the pulley. Release the recoil spring by letting the pulley rotate slowly backwards.
Lift up the starter pulley. See instructions under the heading Changing a broken or worn 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. Fit the starter pulley and tension the recoil spring.

Needle bearing lubrication
The clutch drum has a needle bearing on the output shaft. This needle bearing must be lubricated regularly (once a week). CAUTION! Use a high-quality bearing grease or engine oil. See instructions under the heading Cutting equipment.

34 English

Adjustment of the oil pump
Clean the cooling system with a brush once a week, more often in demanding conditions. A dirty or blocked cooling system results in the machine overheating which causes damage to the piston and cylinder. Note! The cooling system on a chain saw with catalytic converter must be cleaned daily. This is particularly important on chain saws with catalytic converters, because the higher exhaust temperature requires efcient cooling of the engine and the catalytic converter unit.
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. Turning the screw clockwise will reduce the oil ow and turning the screw anticlockwise will increase the oil ow.
Air Injection centrifugal cleaning
Centrifugal cleaning means the following: All air to the carburettor passes through the starter. Dirt and dust is centrifuged out by the cooling fan.
Recommended settings: Bar 13"-15": Position 1 Bar 15"-18": Position 2 Bar 18"-20": Position 3 IMPORTANT! In order to maintain operation of the centrifugal cleaning system it must be regularly maintained. Clean the air intake to the starter, the ns on the ywheel, the space around the ywheel, inlet pipe and carburettor compartment.
WARNING! The engine must not be running when making adjustments.

Cooling system

To keep the working temperature as low as possible the machine is equipped with a cooling system. The cooling system consists of: 5 Air intake on the starter. Air guide plate. Fins on the ywheel. Cooling ns on the cylinder. Cylinder cover (directs cold air over the cylinder).

English 35

Winter use
Running problems can occur when using the machine in the cold and snowy conditions caused by: Too low engine temperature. Icing of the air lter and carburettor. Partly mask the air inlet on the starter to increase the working temperature of the engine. Preheat the intake air to the carburettor by using the heat from the cylinder.

Heated handles

(CS 2156W, CS 2159W) 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. When the switch is pushed downwards, the heat is switched on. When the switch is pushed upwards, the heat is switched off.
Special measures are therefore often required:
