Winter Operation - Stihl MS 200 T Instruction Manual

Releasing the chain brake
N Pull the hand guard back toward the
front handle.
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
MS 200 T
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:
Full-time usage:
Part-time usage:
Occasional usage:

N Take out the screw (1).
N Pull out the shutter (2), turn it over
so that the window is facing down
and then push it back into position.
N Refit the screw (1).
The shutter is now in the winter position.
Heated air is now drawn in from around
the cylinder to help prevent air filter and
carburetor icing.
At temperatures above +50°F
N Return the shutter to the summer
position.
This is necessary to avoid engine
running problems and
overheating.
