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.

In the felling position the left hand is in a position that
makes manual activation of the chain brake
impossible. With this type of grip, that is when the left
hand is placed so that it cannot affect the movement
of the front hand guard, the chain brake can only be
activated by the inertia action.

Will my hand always activate the chain
brake during a kickback?
brake during a kickback?
No. It takes a certain force to move the hand guard forward.
If your hand only lightly touches the front guard or slips
over it, the force may not be enough to trigger the chain
brake. You should also maintain a firm grip of the chain saw
handles while working. If you do and experience a
kickback, your hand may never leave the front handle and
will not activate the chain brake, or the chain brake will only
activate after the saw has swung around a considerable
distance. In such instances, the chain brake might not have
enough time to stop the saw chain before it touches you.

There are also certain positions in which your hand cannot

Will my inertia activated chain brake

always activate during kickback in the
event of a kickback?
No. First your brake must be in working order. Second the
kickback must be strong enough to activate the chain
brake. If the chain brake is too sensitive it would activate
all the time which would be a nuisance.

Will my chain brake always protect me
from injury in the event of a kickback?
from injury in the event of a kickback?
No. First, the chain brake must be in working order to
provide the intended protection. Second, it must be
activated during the kickback as described above to stop
the saw chain. Third, the chain brake may be activated but
if the bar is too close to you the brake might not have
enough time to slow down and stop the chain before the
chain saw hits you.

Throttle lockout
The throttle lockout is designed to prevent accidental
operation of the throttle control. When you press the lock
(A) (i.e. when you grasp the handle) it releases the throttle
control (B). When you release the handle the throttle
control and the throttle lockout both move back to their
original positions. This arrangement means that the
throttle control is automatically locked at the idle setting.

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 instructions under the heading
Assembly) and if the bar and chain are properly serviced
and maintained (see instructions under the heading
General working instructions).

system that is designed to minimize vibration and make
operation easier.
