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 an air filter or with a deformed or broken 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 resultant dust contamination can diminish engine performance.
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)Inner Case
(4)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 retainer to disassemble it. Clean the components with gasoline.
