WARNING
Make sure that the engine has stopped and is cool
before performing any service to the blower. Contact
with rotating blower fan or hot muffler may result in
a personal injury.
AIR CLEANER
• Never operate the blower without the air filter or with
a deformed filter element because unfiltered dusty air
will quickly ruin the engine.
•
Check the air cleaner before use.
A clogged air filter may increase fuel consumption
while cutting down the engine power.
• Never clean a paper filter by striking it with or against
another object. The filter may be damaged and resul-
tant dust contamination can diminish engine perfor-
mance.
CLEANING AIR FILTER:
1. Unscrew 2 knob bolts and remove the air cleaner
cover. Then remove a prefilter mounted inside the air
cleaner cover.

(2) Prefilter
(3) Paper Filter
2. Wash the prefilter in fresh, non flammable cleaning
solution (ex. warm soapy water) and then dry.
(Clean the air filter once in a week.)
3. Exchange the paper filter element with new one in
case it has been contaminated.
WARNING
• This prefilter is dry type.
• Never wash the prefilter in oleaginous cleaning
solution.
• Do not clean a paper filter by striking it.
FUEL FILTER
• A clogged fuel filter may cause poor acceleration of
the engine. Check periodically to see if the filter is
clogged with dirt. The filter can be taken out of the
fueling port using a small wire hook. Disconnect the
filter assembly from the fuel pipe and unhook the re-
tainer to disassemble it. Clean the components with
gasoline.

(3) Holder (4) Retainer
SPARK PLUG
• The spark plug may gather carbon deposits on its
firing end with reasonable use. Remove and inspect
the spark plug every 25 hours and clean the elec-
trodes as necessary with a wire brush. The spark gap
should be adjusted to .025 in (0.6~0.7mm).
• Plug manufacturers recommend replacing the plug
twice a year to avoid unexpected plug failure in a
job.
