    PERSONAL PROTECTIVE EQUIPMENT MOST CHAIN SAW ACCIDENTS HAPPEN WHEN THE CHAIN TOUCHES THE OPERA- TOR. 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.
  • Page 5 1 Chain brake and front hand guard YOUR chain saw is equipped with a chain brake that is desig- ned to stop the chain immediately if you get a kickback. The chain brake reduces the risk of accidents, but only You can prevent them.
  • Page 6: Chain Catcher

    The way the chain brake is triggered, either manually or automatically, depends on the force of the kickback and the position of the chain saw in relation to the object that the kickback zone of the bar strikes. If you get a violent kickback while the kickback zone of the bar is farthest away from you...
  • Page 7: Stop Switch

    5 Vibration damping system Your chain saw is equipped with a vibration damping system that is designed to minimise vibrations and make operation easier. When you use a chain saw vibrations are generated by the uneven contact between the chain and the wood you are cutting.
  • Page 8: Inspecting, Maintaining And Servicing Chain Saw Safety Equipment

    Inspecting, maintaining and servicing chain saw safety equipment SPECIAL TRAINING IS REQUIRED to service and repair chain saws. This is especially true of chain saw safety equipment. If your chain saw fails any of the checks described below take it to your SERVICE AGENT. When you buy any of our products we guarantee the availability of professional repairs and service.
  • Page 9: Throttle Lock

    2 Throttle lock Make sure the throttle control is locked at the idle setting when you release the throttle lock. Press the throttle lock and make sure it returns to its original position when you release it. Check that the throttle control and throttle lock move freely and that the return springs work...
  • Page 10: Cutting Equipment

    7 Muffler Never use a chain saw that has a faulty muffler. Regularly check that the muffler is securely attached to the chain saw. If the muffler on your saw is fitted with a spark arrestor mesh this must be cleaned regularly. A blocked mesh will cause the engine to overheat and may lead to serious...
  • Page 11 1 Cutting equipment designed to minimise kickback Faulty cutting equipment or the wrong combination of bar and chain increases the risk of kickback. Use only the bar and chain combinations recommended in the ”Technical data” section. The only way to avoid kickback is to make sure that the kick- back zone of the bar never touches anything.
  • Page 12 2 Sharpening your chain and adjusting raker clearance The risk of kickback is increased with a badly sharpened chain! A 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 cuttings will be very small.
  • Page 13: Tensioning The Chain

    C General advice on setting raker clearance • When you sharpen the cutting teeth you reduce the RAKER CLEARANCE (cutting depth). To maintain cutting performance you must file back the raker teeth to the recommended height. See the ”Technical data” section to find the raker clearance for your saw chain.
  • Page 14: Lubricating Cutting Equipment

    SAFETY INSTRUCTIONS 4 Lubricating cutting equipment A Chain oil • Chainsaw chain oil must demonstrate good adhesion to the chain and also maintain its flow caracteristics regardless of whether it is warm summer or cold winter weather. • As a chainsaw manufacturer we have developed an optimal chain oil which, with its vegetable oil base, is also biodegradable.
  • Page 15 C Checking chain lubrication • Check the chain lubrication each time you refuel. Aim the tip of the saw at a light coloured surface about 20 cm away. After 1 minute running at 3/4 throttle you should see a distinct line of oil on the light surface.
  • Page 16: How To Avoid Kickback

    H Bar 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 17: General Rules

    General rules If you understand what kickback is and how it happens then you can reduce or eliminate the element of surprise. By being prepared you reduce the risk. Kickback is usually quite mild, but it can sometimes be very sudden and violent.
  • Page 18: General Safety Precautions

    GENERAL SAFETY PRECAUTIONS Chain saws are designed solely for cutting wood. The only cutting equipment that can be used with this chain saw are the combinations of bars and chains recommended in the ”Technical data” section. Never use a chain saw if you are tired, if you have drunk alcohol, or if you are taking medication that...
  • Page 19: General Working Instructions

    • Move the saw at least 3 m from the refuelling point before starting it. • Never start the chainsaw: If you have spilt fuel or chain oil on the saw. Wipe off the spill and allow remaining fuel to evaporate.
  • Page 20: Basic Cutting Technique

    Before moving your chain saw switch off the engine and lock the chain using the chain brake. Carry the saw with the bar and chain pointing backwards. Fit a guard to the bar before carrying the saw any distance. Never put a chain saw down while the engine is running unless you have it in clear view and the...
  • Page 21: Tree Felling Technique

    2 The log is supported at one end. There is a high risk that it will split. A Start by cutting from below (about 1/3 of the way through). B Finish by cutting from above so that the two cuts meet. 3 The log is supported at both ends.
  • Page 22 C Clearing the trunk and preparing your retreat Remove any branches that are in the way. To do this it is best to work from the top down and keep the trunk between you and the chain saw. Never limb above shoulder height.
  • Page 23 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 CUT with single cutting stokes. (See ”Technical data” to find out which lengths of bar are recommended for your saw).

    Mounting guide bar and chain 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. Take off the bar nuts and remove the clutch cover.
  • Page 26: Fuel Handling

    Two-stroke oil • For the best results use HUSQVARNA two-stroke oil, which is especially developed for chain saws. Mixing ratio 1:50 (2%). • If HUSQVARNA two-stroke oil is not available, you may use another two-stroke oil of good quality that is intended for air cooled engines.
  • Page 27: Fuelling

    Chain oil • The chain lubrication system is automatic. Always use special chain oil with good adhesive characteristics. • In countries where no special chain oil is available, EP 90 transmission oil can be used. • Never use waste oil. This results in damage to the oil pump, the bar and the chain.
  • Page 28: Start And Stop

    Start and stop WARNING! • 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 saw away from the fueling area before starting.

    Carburettor Functioning, Basic setting, Final setting WARNING! Do not start the saw without the bar, chain and clutch cover (chain brake) assembled. If you do, the clutch might come loose and cause severe injuries. Operation • The carburettor governs the engine speed via the throttle. Air/fuel are mixed in the carburettor.
  • Page 30: Starter Device

    Starter device WARNING! • When the recoil spring is assembled in the starter housing, it is in tensioned position and can when treated carelessly, pop out and cause injuries. • Always be careful, when changing the recoil spring or the starter cord. Always wear safety goggles for eye protection.

  • Page 32: Adjustment Of The Oil Pump

    Adjustment of the oil pump The oil pump is adjustable. Adjustments are made by turning the screw using a screwdriver or combination spanner. The saw is supplied from the factory with the screw set to position 2. Turning the screw clockwise will reduce the oil flow and turning the screw anti-clockwise will increase the oil flow.
  • Page 33: Daily Maintenance

    Below you will find some general maintenance instructions. If you have more questions, contact your servicing dealer. Daily maintenance 1. Check the throttle trigger for smooth operation.
