Maintenance, replacement, or repair of the emission control device and systems may be performed by any non-road engine repair
establishment or individual.
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
• Check the air cleaner before use.
A clogged air filter may increase fuel consumption while cutting down the engine
power.
• 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.
• Never clean the paper filter by tapping on it. Doing so may break the element,
causing dust to get sucked into the blower and damaging the engine.
CLEANING AIR FILTER:
1. Unscrew 2 knob bolts and remove the air cleaner cover. Then remove the prefilter
mounted inside the air cleaner cover.
(1) Knob Bolt (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 an oily cleaning solution.
• Never include oil in the wash.
• Do not clean the paper filter by tapping on 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.
