GB | Operating Instructions
b) In case of a less strong kickback, the chain brake can
be automatically engaged by consequent contact of
the lever with the left hand.
Consequently: always grip the chainsaw
with both hands. Always remember that the
chain brake doees not trepresent at a total
protection.
It is therefore crucial to avoid all the hazard situations
explained in the previous SAFETY DEVICE CHAPTER
(points of paragraphs A17-A18).
c) The chain brake can be applied manually by pushing
it forward.
d) The brake is released by pulling the lever towards the
front handle (Fig. 31).
e) Before starting each job, check manually that the lever
click releases both forwards and backwards.
It is recommended that the check be performed with the
engine running at minimum and for a short time.
If the click releases do not occur or operation
of the lever has become stiff, do not use the
chainsaw. Contact a qualified service centre.
- Periodically remove all shavings and sawdust from the
visible parts of the chain brake mechanisms.
Do not attempt to repairs or modifications.
Verwenden Sie die Motorsäge nicht, wenn
der Hebel nicht umspringt oder seine Betäti-
gung schwergängig ist. Wenden Sie sich an
eine Kundendienststelle.
8.4 CHAIN
MAINTENANCE AND SHARPENING
- If the chain is not sufficiently lubricated, increase the
oil flow by rotating the setting screw of the pump anti-
clockwise (Fig. 17).

When the chain is properly
sharpened, the work is not
tiring, the cutting yield is
high, and there is no abnor-
mal wear on the mechanical
parts or the bar.
- Before sharpening, the chain must be made
taught by means of the chain tensioner (Fig.
9) see the section on "MOUNTING THE
BAR AND CHAIN ".
- After sharpening, slacken the chain as per the mount-
ing instructions.
- During sharpening, lock the chain, using the brake.
- Use a round file (specific for chains) 5/32" (4 mm) in
diameter (Fig. 18 part.1).
Observe the sharpening angle as in (Fig. 18 part.2-3).
- Sharpen by filing from the inside outwards (Fig.18
part. 5) all the teeth on one side and then all the teeth
on the other.
- Position the blade in such a way that it projects about 1
mm (Fig. 18 part. 4) above the level of the cutting edges.
8.5 "MINIMUM" ENGINE RPM ADJUSTMENT - SCREW [T]
The carburettor of your chainsaw
has been set at standard values
during manufacture. To regulate
minimum engine rpm, only screw
[T] can be used (fig. 19).
Because such adjustment requires
specific training and work tools, al-
ways contact an AUTHORISED
AFTER-SALES SERVICE.
Screw [T]: hold the butterfly valve slightly open so as to
be able to regulate the "MINIMUM" rpm at an appropriate
rotation speed.
CAUTION – HAZARD!! A high adjustment of
the "minimum" rpm could trigger the centrif-
ugal clutch and set the cutting chain in mo-
tion even when the throttle lever is released.
