specific skills and special tools in order to do
the work properly. For safety purposes, we
recommend you contact your Dealer.
Sharpening is necessary when:
• The sawdust looks like dust.
• Cutting becomes more difficult.
• The cut is not straight.
• Vibrations increase.
A specialized centre will sharpen the chain using

Replace the chain whenever:
– The length of the cutting edges reduces to 5
mm or less;
– There is too much play between the links and
the rivets.

THE OIL TANK
(Only if organic oil is used for the chain)
The use of some types of organic oil may cause
deposits or fouling after a certain period of use.
If this happens, before leaving the machine un-
used for a long period of time:
– disassemble the chain and the bar;
– empty the oil tank;
– pour a specific liquid cleanser in the tank, to
about half the maximum level;
