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

wear. It is necessary to have it serviced
and maintained regularly by trained
personnel, such as your STIHL servicing
dealer, at the following intervals:

N Remove the chain sprocket cover –
see "Mounting the Bar and Chain"
N Move the shutter (1) to the winter
position r.
In the winter position cold air is drawn in
along with warm air from around the
cylinder. This helps prevent air filter and
carburetor icing.
At temperatures above +70°F (+20°C)
N Always move the shutter back to the
summer position s.
