• The cut is not straight.
• Vibrations increase.
ATTENTION
Kickback may occur if the chain is not sufficiently
sharpened
DANGER
It is recommended to have an Authorised centre
sharpen the chain using the right tools to ensure
minimum removal of material and even sharpness
on all the cutting edges.
8.2.1 Replacing the toothed chain
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 cutting speed is too slow and the repeated
sharpening does not improve the cutting speed.
The chain is worn.
NOTE
After replacing the chain, its tension level must
be checked more frequently due to settling of the
chain.
8.3 GUIDE BAR MAINTENANCE
ATTENTION
Any work on the guide bar requires specific
experience and special tools in order to achieve
top workmanship standards; for safety purposes,
we recommend you contact your dealer to ensure
work is done correctly.
To avoid asymmetrical wear on the bar, make sure
it is turned over periodically.
To keep the bar in perfect working order, proceed
as follows:
1. grease the bearings on the nose sprocket (if
present) with the syringe (not included).
2. clean the bar groove with the scraper (not
included) (Fig. 24.A);
3. clean the lubrication holes (Fig. 24.B);
4. with a flat file, remove burr from the edges and
level off the guides.
8.3.1 Replacing the bar
Replace the bar whenever:
• the groove is not as deep as the height of the
drive links (which must never touch the bottom);
• the inside of the guide is worn enough
to make the chain lean to one side.
