GENERAL SAFETY PRECA UTIONS
• 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 the chain hitting your left hand 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.
• 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
fi rmly 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.
If the kickback is less violent or the kickback zone of the
bar is closer to you the chain brake is designed to 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.
