Warning!
Do not operate your chainsaw if the
muffler is damaged, missing or modified.
An improperly maintained muffler will
increase the risk of fire and hearing loss.
Never touch a hot muffler or a burn will
result. If your muffler was equipped with
a spark-arresting screen to reduce the
risk of fire (e. g. in the USA, Canada
and Australia), never operate your saw if
the screen is missing or damaged.
Remember that the risk of forest fires is
greater in hot or dry weather. Keep the
chain, bar and sprocket clean; replace
worn sprockets or chains. Keep the
chain sharp.
You can spot a dull chain when easy-to-
cut wood becomes hard to cut or burn
marks appear on the wood. Keep the
chain at proper tension. Tighten all nuts,
bolts and screws except the carburetor
adjustment screws after each use.

Warning!
In order for the chain brake on your
STIHL chainsaw to properly perform its
function of reducing the risk of kickback
and other injuries, it must be properly
maintained. Like an automobile brake, a
chainsaw 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
chainsaw 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 chainsaw 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 please refer to the
maintenance chart
and to the warranty
statement near the end of this manual.
The daily maintenance schedule for your
chainsaw set forth in your STIHL
owner's manual should be strictly
followed.
Store chainsaw in a dry and secure
place and away from children.
Before storing for longer than a few
days, always empty the fuel tank.
