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.
IMPORTANT After replacing the chain,
its tension level must be checked more
frequently due to settling of the chain.
8.3 GUIDE BAR MAINTENANCE
NOTE 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. 27.A);
3. clean the lubrication holes (Fig. 27.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.
