or individual. However, if you make a
warranty claim for a component
which has not been serviced or
maintained properly or if
nonapproved replacement parts were
used, STIHL may deny coverage.
Strictly follow the maintenance and
repair instructions in the appropriate
section in this instruction manual.
Please refer to the maintenance chart in
this instruction manual.
Do not clean your machine with a
pressure washer. The solid jet of water
may damage parts of the machine.
In California, it is a violation of § 4442 or
§ 4443 or the Public Resources Code to
use or operate gasoline-powered tools
on forest-covered, brush-covered or
grass-covered land unless the engine’s
exhaust system is equipped with a
complying spark arrester that is
maintained in effective working order.
The owner/operator of this product is
responsible for properly maintaining the
spark arrester. Other states or
governmental entities/agencies, such as
the U.S. Forest Service, may have
similar requirements. Contact your local
fire agency or forest service for the laws
or regulations relating to fire protection
requirements.
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
instruction 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
instruction 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 this 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 uncon-
tained 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. Your muffler is equipped with a
spark-arresting screen to reduce the
risk of fire; never operate your power
tool if the screen is missing, damaged or
clogged. Remember that the risk of a
brush or forest fire is greater in hot or dry
weather.
