the chainsaw in relation to the object that the kickback
zone of the guide bar strikes. If you get a violent
kickback while the kickback zone of the guide bar is
farthest away from you the chain brake is designed to be
activated by the inertia in the kickback direction.
If the kickback is less violent or the kickback zone of the
guide bar is closer to you the saw 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.
Common questions about kickback
• Will my hand always activate the chain brake during
a kickback?
No. It takes a certain force to move the hand guard
forward. If your hand only lightly touches the front
8
hand 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 chainsaw 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 chainsaw 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 reach the front
hand guard to activate the chain brake; for example,
when the saw chain is held in felling position.
• 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.
Testing the brake is simple, see instructions under
Examination, maintenance and service
the heading
of the product's safety equipment on page 21 . We
recommend you do this before you begin each work
session. 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?
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 guide bar is too close to you the
brake might not have enough time to slow down and
stop the saw chain before the chainsaw hits you.
WARNING: Only you and proper working
technique can eliminate kickback and its
dangers.
Throttle trigger lockout
The throttle trigger lockout is designed to prevent
accidental operation of the throttle trigger. When you
press the throttle trigger lockout down (A) (in example
when you grasp the handle) it releases the throttle
trigger (B). When you let go of the handle, the throttle
trigger and the throttle trigger lockout both return to their
