The chain brake (A) can either be activated manually (by
your left hand) or automatically by the inertia release
mechanism.
The brake is engaged 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 saw chain if
you lose grip of the front handle.
The chain brake must be engaged when the chainsaw 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.
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
chainsaw 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 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
