Locking chain with chain brake
- in an emergency
- when starting
- at idling speed.
@ The chain is stopped and locked
when the hand guard is pushed
toward the bar nose by the left hand -
or when brake is activated by inertia
in certain kickback situations.
Releasing the chain brake
@ = Pull the hand guard back toward
the front handle.
The chain brake is activated by the
inertia of the front hand guard
if the kickback force of the saw is high
enough:
The hand guard is accelerated toward the
bar nose - even if your left hand is not be-
hind the hand guard, e.g. during felling cut.
The chain brake will operate only if the
hand guard has not been modified in any
way.
Check operation of chain brake
Before starting work: Run engine at
idle speed, engage the chain brake (push
hand guard toward bar nose).
Accelerate up to full throttle for no more
than 3 seconds - the chain must not
rotate. The hand guard must be free of dirt
and move freely.
Chain brake maintenance
The chain brake is subject to normal
wear and tear. It must therefore be
checked and serviced regularly by trained
personnel (e.g. STIHL dealer) at the follo-
wing intervals:
Full-time professional
users: every 3 months
Semi-professional
(farm and construcction
industry): every 6 months
Hobby and occasional
users: every 12 months
