How To Service The Air Filter

CAUTION

Do not use pressurized air or solvents to clean the filter. Pressurized air can damage the filter and solvents will dissolve the filter.

WARNING

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.

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.
