How To Service The Air Filter
Do not use pressurized air or solvents to clean the
filter. Pressurized air can damage the filter and
solvents will dissolve the filter.
CAUTION
Gasoline and its vapors are
extremely flammable and explosive.
Fire or explosion can cause severe
burns or death.
• Never start or run the engine with the air
cleaner assembly or the filter removed as a
fire or explosion could result. A dirty air filter
will cause a loss of engine power. If dirt or
dust enters the engine through the carburetor,
the result will be excessive wear or damage to
the engine. Replace a damaged or clogged air
cleaner or air filter immediately.
WARNING
The air filter system uses either a flat or oval
cartridge. Some models also include an additional
pre-cleaner that can be washed and reused.
