9. Maintenance
Maintenance, replacement, or repair of the emission control device and systems may be per-
formed 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
• Never operate the blower without an air filter or with a
deformed or broken filter element.
• 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 the air filter or with a deformed fil-
ter element because unfiltered dusty air will quickly
ruin the engine.
CLEANING AIR FILTER:
• Clean the filter element in warm, soapy water as re-
quired. Dry completely before installing. If the element
is broken or shrunk, replace with a new one.
