    GENERAL SAFETY PRECAUTIONS • The brake is applied when the front hand guard (B) is pushed forwards or when the right-hand brake trigger (E) is pushed up and forwards. • This movement activates a spring-loaded mechanism that tightens the brake band (C) around the engine drive system (D) (clutch drum).

  • Page 10: Chain Catcher

    GENERAL SAFETY PRECAUTIONS 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. You should also maintain a firm grip of the chain saw handles while working.

  • Page 11: Cutting Equipment

    GENERAL SAFETY PRECAUTIONS 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 12: 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 13

    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). When you sharpen a cutting tooth there are four important factors to remember.

  • Page 14: 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 15: Lubricating Cutting Equipment

    GENERAL SAFETY PRECAUTIONS • Adjust the tension on the chain by turning the wheel down (+) for tighter tension and up (-) to loosen the tension. • Tighten the bar clutch by turning the knob clockwise. • Fold the knob back in to lock the tensioning. Lubricating cutting equipment WARNING! Poor lubrication of cutting equipment may cause the chain to snap,...

    GENERAL SAFETY PRECAUTIONS • Check that the bar tip sprocket turns freely and that the lubricating hole in the tip sprocket is not blocked. Clean and lubricate if necessary. If the chain lubrication system is still not working after carrying out the above checks and associated measures you should contact your servicing dealer.

    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 19: Fuel Handling Fuel

    When working with continuous high revs (e.g. limbing) a higher octane is recommended. Environment fuel HUSQVARNA recommends the use of alkylate fuel or environmental 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 20: Fueling

    • Contact your service agent when choosing chain oil. 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.

  • Page 21: 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.

    Cutting with the bottom edge of the bar, i.e. from the top of the object downwards, is known as cutting with a pulling chain. 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 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.

  • Page 27: 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 28

    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 29: 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 30: 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.
