    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.
  • Page 7: Personal Protective Equipment

    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.
  • Page 8 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).
  • Page 9: Chain Catcher

    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.
  • Page 10: Cutting Equipment

    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).
  • Page 11 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.
  • Page 12: Sharpening Your Chain And Adjusting Depth Gauge Setting

    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.
  • Page 13: Lubricating Cutting Equipment

    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.
  • Page 14 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.
  • Page 15 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.
  • Page 16: Assembly

    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.
  • Page 17 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.
  • Page 18: Fuel Handling

    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).
  • Page 19: Fueling

    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.
  • Page 20: Starting And Stopping

    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.
  • Page 21: Starting And Stopping

    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.
  • Page 22: Working Techniques

    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.
  • Page 23: General Rules

    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.
  • Page 24: Basic Cutting Technique

    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.
  • Page 25 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.
  • Page 26: Tree Felling Technique

    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.
  • Page 27 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.
  • Page 28: Freeing A Tree That Has Fallen Badly

    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.
  • Page 29: How To Avoid Kickback

    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.
  • Page 30: 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 Due to existing environmental and emissions legislation your chain saw is equipped with movement limiters on the carburetor adjuster screws.
  • Page 31: Checking, Maintaining And Servicing Chain Saw Safety Equipment

    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.
  • Page 32: Stop Switch

    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.
  • Page 33: Muffler

    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.
  • Page 34: Air Filter

    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.
  • Page 35: Spark Plug

    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.
  • Page 36: Turbo Air Cleaning" Centrifugal Cleaning

    ”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.
