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 every 25 hours of use or more
frequently if used under dusty conditions. A clogged
air filter may increase fuel consumption while cutting
down the engine power. Never operate the blower
without the air filter or with a deformed filter element
because unfiltered dusty air may quickly ruin the
engine.
CLEANING AIR FILTER:
1. Remove the air cleaner cover.
2. Use neutral detergent and warm water to clean the
filter element. After cleaning, air dry the element
completely.
3. Reinstall the filter.
Never forget to attach the screen. If the screen is not
attached, the cleaner will not seal properly and the
dusts come into the cylinder.

■ 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.

■ 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
electrodes as necessary with a wire brush. The
spark gap should be adjusted to .025 in
(0.6~0.7mm).
