2.Air cleaner service
A dirty air cleaner will restrict air flow to the carburetor. To prevent
carburetor malfunction, service the air cleaner regularly. Service more
frequently when operating the power head in extremely dusty areas.
Never use gasoline or low flash point solvents for cleaning the air
cleaner element. A fire or explosion could result.
CAUTION:
Never run the engine without the air cleaner. Rapid engine wear will
result.
