Always stop the engine and make sure
that the fan is stopped before doing any
maintenance or repair work or cleaning
the blower. Do not attempt any main-
tenance or repair work not described in
your owner’s manual. Have such work
performed at your STIHL service shop
only.
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.

A worn or damaged muffler is a fire
hazard and may cause loss of hearing.
Check to see that the muffler is in good
condition. The blower must not be
operated if the muffler is not functioning
properly or has been removed.
Remember that the risk of forest fires is
greater in hot weather. Use the spark
arresting muffler supplied with the unit.
Never touch a hot muffler or burn will
result.
:DUQLQJ
In order to reduce the risk of fire, do not
modify or remove any part of the muffler
or spark arrestor.
Tighten all nuts, bolts and screws except
the carburetor adjustment screws after
each use.
Keep spark plug and wire connection
tight and clean. The spark plug electrode
gap should be checked with a feeler
gauge at least every 50 operating hours
and reset if necessary. Fit a new spark
plug if the electrodes are badly pitted.
Store blower in a dry, high or locked
location place and out of reach of
children.
Before storing for longer than a few
days, always empty the fuel tank.
