Due to the heat from the catalytic
reaction, these screens will normally
stay clean and need no service or
maintenance. If you experience loss of
performance and you suspect a clogged
screen, have your muffler maintained by
a STIHL servicing dealer.
MAINTENANCE, REPAIR AND
STORING
Strictly follow the maintenance and
repair instructions in the appropriate
section of your instruction manual.
Please refer to the maintenance chart in
this manual.
Tighten all nuts, bolts and screws except
the carburetor adjustment screws after
each use.
For maintenance items please also refer
to the maintenance chart in this manual.
Store the power tool in a dry and high or
locked location out of reach of children.
Before storing for longer than a few
days, always empty the fuel tank. See
chapter "Storing the machine" in this
manual.
Store fuel in an approved and properly
labeled safety-type canister only. Take
care when handling gasoline! For health
and safety reasons, avoid direct contact
with the skin and avoid inhaling fuel
vapor!
Warning!
Use only identical STIHL replacement
parts for maintenance and repair. Use
of non-STIHL parts may cause serious
or fatal injury.
Warning!
Always stop the engine and make sure
that the fan is stopped before doing any
maintenance or repair work or cleaning
the power tool. Do not attempt any
maintenance or repair work not
described in your instruction manual.
Have such work performed by your
STIHL servicing dealer only.
Warning!
Use the specified spark plug and make
sure it and the ignition lead are always
clean and in good condition. 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 securely attached.) A
loose connection between spark plug
terminal and the ignition wire connector
in the boot may create arcing that could
ignite combustible fumes and cause a
fire.
Warning!
Never test the ignition system with the
boot removed from the spark plug or
with a removed spark plug, since
uncontained sparking may cause a fire.
Warning!
Do not operate your power tool if the
muffler is damaged, missing or modi-
fied. An improperly maintained muffler
will increase the risk of fire and hearing
loss. If your muffler was equipped with
a spark-arresting screen to reduce the
risk of fire, never operate your power
tool if the screen is missing or dam-
aged. Remember that the risk of forest
fires is greater in hot or dry weather.
