from the tool and wear heavy-duty gloves.
•
All the maintenance operations which are not described in this manual have to be performed in Authorised
Service Centres.

6.1.1 Chain tension adjustment check
Periodically check the tension of the chain and adjust it if necessary, following the procedure shown in paragraph

Do not tension the chain when it is elongated due to heat. Wait for it to cool down before adjusting it again.
IMPORTANT!
If the chain is new, it requires a break-in period during which its tension must be checked more often.
6.1.2 Check and replacement of the chain and/or cutting bar
NOTE!
Replace the
chain
when after sharpening it many times, the length of the tooth reaches 3-4 millimetres or
when the links of the chain are worn.
