5.4 CHAIN BRAKE

This is a safety braking system that blocks
chain movement when kickback occurs
during cutting. Kickbacks occur following
an irregular contact of the tip of the bar, with
a rapid upward movement of the bar that
causes the hand to strike the front guard.
It must be manually released to
disengage the chain brake.
Chain brake engaged.
This is achieved when the
front hand guard is pushed
all the way forward.
Chain brake disengaged. This
is achieved when the front hand
guard is pulled all the way back,
towards the machine body,
until it clicks into position.
Do not use the machine if the chain
brake does not function correctly and
have it inspected by your dealer.

6.1.2 Filling with chain lubrication oil
Fill with chain lubrication oil before using
the machine. For oil filling methods and
precautions (see paragraph 7.3).
6.1.3 Checking the chain tension
Perform all operations
with the motor off.
Check the chain tension.
The tension is correct when the drive links
do not slip out of the chain guides if you hold
the chain in the middle of the bar (Fig. 7).
To adjust the chain tension:
1. loosen the cover nuts, using
the supplied wrench;
2. turn the chain tension adjuster screw (Fig.
-
5.D) to achieve the desired tension;
+
3. raise the bar and tighten the guard nuts
securely using the wrench (Fig. 8.A).
Never work with the chain loose,
as it can be hazardous if the chain
slips out of the bar guides.
IMPORTANT During the first period of use
(or after replacing the chain) it must be checked
more frequently due to settling of the chain.
