Use only identical STIHL replacement
parts for maintenance and repair.
Use of non-STIHL parts may cause
serious or fatal injury.
Follow the maintenance and repair
instructions in the appropriate section of
your owner’s manual. Please refer to the
maintenance chart at the last pages of
this manual.

Always stop the engine and make sure
that the cutting tool is stopped before
doing any maintenance or repair work or
cleaning the brushcutter. 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.


Never repair damaged cutting attach-
ments by welding, straightening or
modifying the shape. This may cause
parts of the cutting tool to come off and
result in serious or fatal injuries.


Check condition of cutting tool at regular
short intervals. If behavior of tool
changes, check it immediately for tight-
ness or any signs of cracks in
particular. Replace damaged or dull
cutting tools immediately, even if they
have only superficial cracks. If the
blade loosens after being properly
tightened, the retaining nut may be
worn or damaged and should be
replaced. If the blade continues to
loosen, see your STIHL dealer. Do not
attach any blade to a unit without
proper installation of all required parts.
Never use unauthorized parts to secure
the blade. Failure to use the proper
parts may cause the blade to fly off
and seriously injure the operator or
bystanders.

To reduce the risk of fire and burn
injuries, check fuel filler cap for leaks at
regular intervals. Use the specified
spark plug and make sure it and the
ignition lead are always in good
condition.

:DUQLQJ
Never test the ignition system with
ignition wire boot removed from
spark plug or with unseated spark plug,
since uncontained sparking may cause
a fire.


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 boot of the
proper size. (Note: If boot has
detachable SAE adapter nut, it must be
attached.) A loose connection between
spark plug boot 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.
