changing the saw chain or cleaning the
saw. Do not attempt any maintenance or
repair work not described in your
Owner's Manual. Have such work
performed at your STIHL service shop
only.
!
Warning!
Never test the ignition system with
ignition wire terminal removed from
sparkplug or with unseated spark plug,
since uncontained sparking may cause
a fire.
!
Warning!
To reduce the risk of fire and burn injury,
use only spark plugs authorized by
STIHL. Always press spark plug boot
snugly onto spark plug terminal of the
proper size. (Note: If terminal has
detachable SAE adapter nut, it must be
attached see chapter entitled „Checking
the Spark Plug.") A loose connection
between spark plug terminal and ignition
wire connector in the boot may create
arcing that could ignite combustible
fumes and cause a fire. Keep spark plug
clean, and make sure ignition lead is in
good condition.
!
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 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. Remem-
ber 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 and 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.
Additionally, the daily maintenance
schedule for your chainsaw set forth in
your STIHL Owner's Manual should be
strictly followed.
Store chainsaw 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 this manual).
