    Always have fire extinguishing tools available if you should need them. Help prevent forest fires. This top handle chainsaw is designed specifically for tree surgery and maintenance in the tree. Due to the special compact handle design (closely spaced handles), there is an increased risk of losing control.
  • Page 8 GENERAL SAFETY PRECA UTIONS Chain brake and front hand guard Your chain saw is equipped with a chain brake that is designed to stop the chain if you get a kickback. The chain brake reduces the risk of accidents, but only you can prevent them.
  • Page 9 GENERAL SAFETY PRECAUTIONS If the kickback is less violent or the kickback zone of the bar is closer to you the chain brake will be activated manually by the movement of your left hand. • In the felling position the left hand is in a position that makes manual activation of the chain brake impossible.

  • Page 10: Cutting Equipment

    GENERAL SAFETY PRECAUTIONS with cutting equipment that is blunt or faulty (wrong type or badly sharpened) will increase the vibration level. WARNING! Overexposure to vibration can lead to circulatory damage or nerve damage in people who have impaired circulation. Contact your doctor if you experience symptoms of overexposure to vibration.

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

    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 Husqvarna. See instructions under the heading Technical Data for a list of replacement bar and chain combinations we recommend.
  • Page 12 GENERAL SAFETY PRECAUTIONS • The cutting part of the chain is called the cutter and consists of a cutting tooth (A) and the depth gauge (B). The cutters cutting depth is determined by the difference in height between the two (depth gauge setting).

  • Page 13: Tensioning The Chain

    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. However, this safety feature requires that you use the right sort of chain oil (if the oil is too thin it will run out before the fuel), and that you adjust the carburetor as...
  • 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.

    Fitting the bar and chain 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. Unscrew the bar nut and remove the clutch cover (chain brake).

  • Page 17: Fuel Handling

    FUEL HANDLING Mixing ratio 1:50 (2%) with HUSQVARNA two-stroke oil or JASO FC or ISO EGC GRADE. 1:33 (3%) with oils class JASO FB or ISO EGB formulated for air-cooled, two-stroke engines.

  • Page 18: Fuelling

    Fuelling 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 19: 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 20: Starting And Stopping

    the engine starts, quickly apply full throttle; the throttle start lock will automatically disengage. IMPORTANT! As the chain brake is still engaged the speed of the engine must be set to idling as soon as possible, this is achieved by quickly disengaging the throttle lock.

  • Page 21: Working Techniques

    Before use: Check that the chain brake works correctly and is not damaged. Check that the throttle lockout works correctly and is not damaged. Check that the stop switch works correctly and is not damaged. Check that all handles are free from oil. Check that the anti vibration system works and is not damaged.

    suddenly. Take great care when working on sloping ground. Take great care when cutting a tree that is in tension. A tree that is in tension may spring back to its normal position before or after being cut. If you position yourself incorrectly or make the cut in the wrong place the tree may hit you or the machine and cause you to lose control.
  • Page 23 The chainsaw should be fitted with a suitable strop for attaching to the operator’s harness: a) choke the strop around the attachment point on the rear of the saw.

    30 cm away from the trapped saw. Whether a handsaw or a chainsaw is used to free a stuck saw, the release cuts should always be outboard (toward the tips of the branch), in order to prevent the saw being taken with the section and further complicating the situation.
  • Page 25 Make sure the chain will not strike the ground or any other object during or after cutting. Is there a risk of kickback? Do the conditions and surrounding terrain affect how safely you can stand and move about? Two factors decide whether the chain will jam or the object that you are cutting will split: the first is how the object is supported before and after cutting, and the second is whether it is in tension.

    Limbing When limbing thick branches you should use the same approach as for cutting. Cut difficult branches piece by piece. Felling technique for tree tops WARNING! It takes a lot of experience to fell a tree. Inexperienced users of chain saws should not fell trees.

  • Page 27: Freeing A Tree That Has Fallen Badly

    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°. 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.

  • Page 28: How To Avoid Kickback

    General advice: Position yourself so that you will be clear of the tree or branch when the tension is released. Make one or more cuts at or near the point of maximum tension. Make as many cuts of sufficient depth as necessary to reduce the tension and make the tree or branch break at the point of maximum tension.

    A damaged air filter must always be replaced. A HUSQVARNA 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: Adjustment Of The Oil Pump

    Adjustment of the oil pump The oil pump is adjustable. Adjustments are made by turning the screw with a screwdriver. Turning the screw clockwise will increase the oil flow, turning it anticlockwise will reduce the oil flow. The oil tank should become nearly empty by time fuel is used up.
