16.1 Saw chain, lock
143BA011 KN
–
in an emergency
–
when starting
–
when idling
Press the hand guard towards the nose of the
guide bar with the left hand - or automatically
due to kickback: Saw chain is blocked - and
stops running.
16.2 Disengage the chain brake.
143BA012 KN
► Pull the hand guard back towards the front
handle.
NOTICE
The chain brake must be released before open‐
ing the throttle (except during functional check‐
out) and before sawing.
Running the engine at high revs with the chain
brake engaged (chain locked) will quickly dam‐
age the engine and chain drive (clutch, chain
brake).
The chain brake is also activated by the inertia of
the front hand guard if the kickback force of the
saw is high enough: The hand guard is acceler‐
ated toward the bar nose – even if your left hand
is not behind 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.
16.3 Checking Operation of the
Chain Brake
Before starting work: Run engine at idle speed,
engage the chain brake (push hand guard
towards bar nose) and open the throttle wide for
(no more than 3 seconds) – the chain must not
rotate. The hand guard must be free of dirt and
easily moveable.
16.4 Chain Brake Maintenance
The chain brake is subject to (normal wear). It is
necessary to have it serviced and maintained
regularly by trained personnel. STIHL recom‐
mends that maintenance and repair work be car‐
ried out only by authorised STIHL dealers. The
following intervals must be complied with:
Full-time use: quarterly
Part-time use: every six months
occasional use: annually
