Before starting each job:

backwards.

MAINTENANCE
DANGER!! Do not carry out any checking, maintenance and repair
operations with the engine running.
Chain-maintenance and sharpening
- If the chain is correctly sharpened, using the chain saw will be effortless,
a better cutting performance will be achieved, and no excessive wear
and tear of the mechanical parts and of the guide bar will occur.
- Before sharpening, the chain must be taut by means of the chain
tensioner (fig.13) see chapter ASSEMBLY- "INSTALLING THE GUIDE
BAR AND CHAIN".
- After sharpening, slacken the chain by following the installation
instructions.
- Use a round file (specially designed for chains) with a 5/32" (4.0 mm)
diameter, fig.41 item 1.
