 8.3.1  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.

 8.4  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. 37.A);

3. 

clean the lubrication holes (Fig. 37.B);

4. 

with a flat file, remove burr from the 

edges and level off the guides.

 8.4.1  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.
