Maintenance, replacement, or repair of the emission control device and
systems may be performed by any non-road engine repair establishment or
individual.
9. Maintenance
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 because unfiltered dusty air
will quickly ruin the engine.
• Check the air cleaner before use.
A clogged air filter may increase fuel
consumption while cutting down the
engine power.
• Never clean a paper filter by striking it
with or against another object. The filter
may be damaged and resultant dust
contamination can diminish engine
performance.
CLEANING AIR FILTER:
1. Unscrew 2 knob bolts and remove the
air cleaner cover. Then remove a
prefilter mounted inside the air cleaner
cover.
