  • 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 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 has a vegetable oil base.
  • 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.

    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

    • 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.
