6 – English
6 The way the chain brake is triggered, either manually or
automatically, depends on the force of the kickback and the
position of the chain saw in relation to the object that the
kickback zone of the bar strikes.
If you get a violent
kickback while the
kickback zone of the bar
is farthest away from you
the chain brake will be
activated by the
movement of the
counterweight (INERTIA
ACTIVATED).
If the kickback is less
violent or the kickback
zone of the bar is closer
to you the chain brake will
be activated manually by
the movement of your left
hand.
7 During felling your left
hand grasps the front
handle in such a way that
it cannot activate the front
hand guard. In this
position the chain brake
can only be activated by
the inertia action of the
counterweight.
The inertia activated
chain brake increases
your safety but there are
certain factors to
remember (see point 6
above).
2 Throttle lock
The throttle lock is designed
to prevent accidental opera-
tion of the throttle control.
When you press the lock (A)
(i.e. when you grasp the
handle) it releases the throttle
trigger (B).
When you release the handle
the throttle trigger and the
throttle lock both move back
to their original positions. This
movement is controlled by two
independent return springs.
This arrangement means that
the throttle control is
automatically locked at the
idle setting when you release
the handle.
3 Chain catcher
The chain catcher is designed
to catch the chain if it snaps or
jumps off. This should not
happen if the chain is properly
tensioned (see section on
”Assembly”
) and if the bar and
chain are properly serviced
and maintained.
(See section on
”General
working instructions”
).
4 Right hand guard
Apart from protecting your
hand if the chain jumps or
snaps, the right hand guard
stops branches and twigs
from interfering with your grip
on the rear handle.
