MS 201 T
The chain brake must be released
before opening the throttle (except
during functional checkout) and before
sawing.
Running the engine at high revs with the
chain brake engaged (chain locked) will
quickly damage the engine and chain
drive (clutch, chain brake).
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.
The chain brake functions only if the
hand guard has not been modified in any
way.
Checking the chain brake for proper
functioning
Each time before starting work: Block
the chain while the engine is idling (hand
guard towards the nose of the guide bar)
and accelerate the engine up to full
throttle briefly (3 sec. max.) – the saw
chain must not rotate. 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
Part-time use: every six
months
