NOTICE
Always disengage chain brake before
accelerating engine and before starting
cutting work. The only exception to this
rule is when you check operation of the
chain brake.
High revs with the chain brake engaged
(chain locked) will quickly damage the
powerhead and chain drive (clutch,
chain brake).
The chain brake is designed to be
activated also by the inertia of the front
hand guard if the forces are sufficiently
high. The hand guard is accelerated
toward the bar nose - even if your left
hand is not behind the hand guard, e.g.
during a felling cut. The chain brake will
operate only if it has been properly
maintained and 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.
Chain brake maintenance
The chain brake is subject to normal
wear. It is necessary to have it serviced
and maintained regularly by trained
personnel, such as your STIHL servicing
dealer, at the following intervals:
