WARNING
In order for the chain brake on your
STIHL chain saw to properly perform its
function of reducing the risk of kickback
and other injuries, it must be properly
maintained. Like an automobile brake, a
chain saw chain brake incurs wear each
time it is engaged.
The amount of wear will vary depending
upon usage, conditions under which the
saw is used and other factors. Excessive
wear will reduce the effectiveness of the
chain brake and can render it
inoperable.
For the proper and effective operation of
the chain brake, the brake band and
clutch drum must be kept free of dirt,
grease and other foreign matter which
may reduce friction of the band on the
drum.
For these reasons, each STIHL chain
saw should be returned to trained
personnel such as your STIHL servicing
dealer for periodic inspection and
servicing of the brake system according
to the following schedule:
Heavy usage – every three months,
Moderate usage – twice a year,
Occasional usage – annually.

The chain saw should also be returned
immediately for maintenance whenever
the brake system cannot be thoroughly
cleaned or there is a change in its
operating characteristics.
For any maintenance of the emission
control system please refer to the
maintenance chart and to the limited
warranty statement near the end of the
instruction manual.
Do not clean your machine with a
pressure washer. The solid jet of water
may damage parts of the machine.
Store chain saw in a dry place and away
from children. Before storing for longer
than a few days, always empty the fuel
tank (see chapter "Storing the Machine"
in the instruction manual).
Cutting Attachment
A cutting attachment consists of the saw
chain, guide bar and chain sprocket.
The cutting attachment that comes
standard is designed to exactly match
the chain saw.
