Winter Operation - Stihl MS 441 Instruction Manual

English
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 accelerated 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.
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 from dirt and move freely.

performed by a STIHL servicing dealer
at the following intervals:
Full-time professional
users: every 3
months
Semi-professional

and construction): every 6
months
Hobby and
occasional users: every 12
