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 re- sultant dust contamination can diminish engine per- formance.
CLEANING AIR FILTER:
1.Unscrew 2 knob bolts and remove the air cleaner cover. Then remove a prefilter mounted inside the air cleaner cover.
(1) Knob Bolt
(2) Prefilter
(3) Paper Filter
2.Wash the prefilter in fresh, non flammable cleaning solu- tion (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 solu- tion.
•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 us- ing a small wire hook. Disconnect the filter assembly from the fuel pipe and unhook the retainer to disassemble it. Clean the components with gasoline.

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.
