- The fuel of your chain saw has been factory set
on standard values (fig.21).
- The screw [t]: keeps the butterfly valve in a
slightly open position in order to adjust the engine
"iDLE " speed at the correct rotation speed.
WARNiNG DANGER!! A high "idle"
speed adjustment can cause the operation of
the centrifugal clutch and therefore operate
the cutting chain even if the throttle lever is
released.
- The engine idle speed is increased by turning
the screw clockwise.

with the engine running.
9.1 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.
- If the chain is under-lubricated, increase the
oil flow by turning the oil pump adjusting screw
anticlockwise (fig.19).
- Before sharpening, the chain must be
taut by means of the chain tensioner
(fig.10) see chapter "INSTALLING THE
GUIDE BAR AND CHAIN".
- After sharpening, slacken the chain by following
the installation instructions.
- During the sharpening operation, lock the chain
in position by applying the brake.
- Use a round file (specially designed for chains)
with a 5/32" (4.0 mm) diameter, fig.20 item 1.
Check the sharpening angles as shown in (fig.20
items 2-3).
