The coasting brake brings the running
chain to a standstill when you let go of
the trigger switch.
1 Coasting brake off
2 Coasting brake activated
Locking chain with chain brake
– in an emergency
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
N Pull the hand guard back towards
the front handle
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:
– Disengage the chain brake
– Switch on the chain saw
– Push hand guard in direction of bar
nose. The chain brake is working
properly if the chain comes to a
standstill within a few fractions of a
second
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:
