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.
