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.

Maintenance, replacement, or repair of the emission control device and systems may be
performed by any non-road engine repair establishment or individual.
• 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 will quickly ruin the engine.
CLEANING AIR FILTER:
Clean the filter element in warm, soapy
water as required. Dry completely before
installing. If the element is broken or shrunk,
replace with a new one.
