GENERAL SAFETY PRECAUTIONS
English – 13
The cutting teeth need to be sharpened when:
• Sawdust becomes powder-like
• You need extra force to saw in
• The cut way does not go straight
• Vibration increases
• Fuel consumpion increases
Sharpening cutting teeth
Make sure the saw chain is held securely, before filing!
• Place your flle on the cutting teeth and push straight
forward. Keep the flle position as illustrated.
Use a round file of proper size for your chain.
After every cutting tooth has been set, check the depth
gauge and flle it to the proper level as illustrated.
1 Appropriate gauge checker
2 Make the shoulder round
3 Depth gauge standard
Make sure every cutting tooth has the same lenght and
egde angels as illustrated.
1 Cutting teeth lenght
2 Filing angle
3 Side plate angle
4 Top plate cutting angle
When the length of the cutting teeth has worn down to
only 5/32 inch (4 mm) the chain must be replaced.
Bar
Reverse the bar occasionally to prevent partial wear.
The bar rail should always be square. Check for wear of
the bar rail.
Tensioning the chain
The more you use a chain the longer it becomes. It is
therefore important to adjust the chain regularly to take up
the slack.
Check the chain tension every time you refuel. NOTE! A
new chain has a running-in period during which you
should check the tension more frequently.
Tension the chain as tightly as possible, but not so tight
that you cannot pull it round freely by hand.
• Loosen the bar nuts that hold the clutch cover/chain
brake. Use the combination spanner. Then tighten the
bar nuts by hand as tight as you can.
Important Always wear gloves, when working with the
chain, in order to protect your hands from injury.
