The chain brake (A) can either be activated manually
(by your left hand) or automatically by the inertia
release mechanism.
The brake is applied when the front hand guard (B) is
pushed forwards.
This movement activates a spring-loaded mechanism
that tightens the brake band (C) around the engine
drive system (D) (clutch drum).
The front hand guard is not designed solely to activate
the chain brake. Another important feature is that it
reduces the risk of your left hand hitting the chain if
you lose grip of the front handle.
The chain brake must be engaged when the chain
saw is started to prevent the saw chain from rotating.
Use the chain brake as a ”parking brake” when
starting and when moving over short distances, to
reduce the risk of moving chain accidentally hitting
your leg or anyone or anything close by. Do not leave
the chain saw switched on with the chain brake
activated for long periods. The chain saw can become
very hot.
To release the chain brake pull the front hand guard
backwards, towards the front handle.
Kickback can be very sudden and violent. Most
kickbacks are minor and do not always activate the
chain brake. If this happens you should hold the chain
saw firmly and not let go.
The way the chain brake is activated, either manually
or automatically by the inertia release mechanism,
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 is
designed to be activated by the inertia in the kickback
direction.
