■ 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.
