GENERAL SAFETY PRECA UTIONS Bef ore 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.
GENERAL SAFETY PRECA UTIONS chain sa w usage if possible. Your dealer, forestry school or your library can provide information about which training materials and courses are available. Work is constantly in progress to improve the design and technology - improvements that increase your safety and efﬁciency.
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. • This movement activates a spring-loaded mechanism that tightens the brake band (C) around the engine drive system (D) (clutch drum).
GENERAL SAFETY PRECAUTIONS so that it cannot affect the movement of the front hand guard, the chain brake can only be activated by the inertia action. Will my hand always activate the chain brake during a kickback? No. It takes a certain force to move the hand guard forward. If your hand only lightly touches the front guard or slips over it, the force may not be enough to trigger the chain brake.
GENERAL SAFETY PRECAUTIONS The machine′s vibration damping system reduces the transfer of vibration between the engine unit/cutting equipment and the machine′s handle unit. The body of the chain saw, including the cutting equipment, is insulated from the handles by vibration damping units. Cutting hardwoods (most broadleaf trees) creates more vibration than cutting softwoods (most conifers).
To maintain the safety features of the cutting equipment, you should replace a worn or damaged bar or chain with a bar and chain combinations recommended by Jonsered. See instructions under the heading Technical Data for a list of replacement bar and chain combinations we recommend.
GENERAL SAFETY PRECAUTIONS Sharpening your chain and adjusting depth gauge setting General information on sharpening cutting teeth • Never use a blunt chain. When the chain is blunt you have to exert more pressure to force the bar through the wood and the chips will be very small.
GENERAL SAFETY PRECAUTIONS Adjustment of depth gauge setting • The cutting teeth should be newly sharpened before adjusting the depth gauge setting. We recommend that you adjust the depth gauge setting every third time you sharpen the cutting teeth. NOTE! This recommendation assumes that the length of the cutting teeth is not reduced excessively.
GENERAL SAFETY PRECAUTIONS Filling with chain oil • All our chain saws have an automatic chain lubrication system. On some models the oil ﬂow is also adjustable. • The saw chain oil tank and the fuel tank are designed so that the fuel runs out before the saw chain oil.
GENERAL SAFETY PRECAUTIONS Check regularly: • Whether there are burrs on the edges of the bar. Remove these with a ﬁle if necessary. • 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.
Check the chain tension regularly. A correctly tensioned chain ensures good cutting performance and long life. CS 2255 with tool-less chain tensioner Check that the chain brake is in disengaged position by moving the front hand guard towards the front handle.
Remove the knob and remove the clutch cover (chain brake). Take off the transportation ring.(A) 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.
When working with continuous high revs (e.g. limbing) a higher octane is recommended. Environment fuel JONSERED recommends the use of alkylate fuel or environment fuel for four-stroke engines blended with two- stroke oil as set out below. Note that carburetor adjustment may be necessary when changing the type of fuel (see instructions under the heading Carburetor).
Fueling WARNING! Taking the following precautions, will lessen the risk of ﬁre: 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.
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.
STARTING AND STOPPING As the chain brake is still activated the engine must return to idling speed as soon as possible by disengaging the throttle latch in order to avoid unnecessery wear on the clutch assembly. 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.
Before use: 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. 4 Check that the stop switch works correctly and is not damaged.
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.
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 can lead to a kickback. Cutting with the bottom edge of the bar, i.e.
Limbing When limbing thick branches you should use the same approach as for cutting. Cut difﬁcult branches piece by piece. Cutting 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.
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 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.
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 ﬁnish with the felling cut.
We recommend that you use a bar that is longer than the diameter of the tree, so that you can make the felling cut and directional cuts with single cutting strokes. See instructions under the heading Technical data section to ﬁnd out which lengths of bar are recommended for your saw.
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.
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 Due to existing environmental and emissions legislation your chain saw is equipped with movement limiters on the carburetor adjuster screws.
Correctly adjusted carburetor When the carburetor is correctly adjusted the machine accelerates without hesitation and the machine 4-cycles a little at max. speed. It is also important that the chain does not rotate at idle. If the L-jet is set too lean it may cause starting difﬁculties and poor acceleration.
Throttle lockout • Make sure the throttle control is locked at the idle setting when the throttle lockout is released. • Press the throttle lockout and make sure it returns to its original position when you release it. • Check that the throttle control and throttle lockout move freely and that the return springs work properly.
Mufﬂer Never use a machine that has a faulty mufﬂer. Regularly check that the mufﬂer is securely attached to the machine. Some mufﬂers are equipped with a special spark arrestor screen. If your machine has this type of mufﬂer, you should clean the screen at least once a week.
The ﬁlter must therefore be replaced with a new one at regular intervals. A damaged air ﬁlter must always be replaced. A JONSERED chain saw can be equipped with different types of air ﬁlter according to working conditions, weather, season, etc. Contact your dealer for advice.
Spark plug The spark plug condition is inﬂuenced by: • 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.
”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 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 Clean the outside of the machine. Check that the components of the throttle control work safely.
Recommended original and replacement bar and chain combinations Following is a list of recommended cutting equipment for the Jonsered chain saw model CS 2255. The combinations of power head, bar and chain have been tested and found to be in accordance with the kickback and vibration requirements of ANSI B 175.1–2000.
