Chain Brake

Blocking the chain
in an emergency
–
Press the hand guard towards the nose
of the guide bar with the left hand (ƒ
position) – or automatically due to
kickback: Saw chain is blocked - and
stops running.
Releasing the chain brake
Pull the hand guard toward the
N
handlebar (‚ position)
The chain brake is activated
automatically by a sufficiently strong
kickback – due to the mass inertia of the
hand guard: The hand guard shoots
forward toward the nose of the guide bar
– even if the left hand is not on the
handlebar behind the hand guard, for
example, when making a horizontal cut.
The chain brake functions only if the
hand guard has not been modified in any
way.
Checking the chain brake for proper
functioning

The chain brake is OK if the saw chain is
stopped within fractions of a second.
The hand guard must be free of dirt and
easily moveable.
Servicing the chain brake
The chain brake is subject to wear due
to friction (normal wear). In order for it to
fulfill its function, it must be serviced and
maintained periodically by trained
personnel. STIHL recommends that
maintenance and repair work be carried
out only by authorized STIHL dealers.
The following intervals must be complied
with:
Full-time use: quarterly
