MAINTENANCE, REPAIR AND
STORING
Maintenance, replacement, or repair
of the emission control devices and
systems may be performed by any
nonroad engine repair establishment
or individual. However if you claim
warranty for a component which has
not been serviced or maintained pro-
perly or if nonapproved replacement
parts were used, STIHL may deny
warranty.
Use only identical STIHL replacement
parts for maintenance and repair.
Use of parts manufactured by others
may cause serious or fatal injury.
Follow the maintenance and repair
instructions in the appropriate section of
your owner's manual. Refer to the
maintenance chart at the last pages of
this manual.
!Warning!
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 mainten-
ance 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.
!Warning!
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
opera-
ted if the muffler is not functioning pro-
perly 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.
!Warning!
In order to reduce the risk of fire, do not
modify or remove any part of the muffler
or spark arrestor.
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.
For any maintenance please refer to the
maintenance chart and to the warranty
statement near the end of this manual.
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.
