(2) Air cleaner service
A dirty air cleaner will restrict air flow to the carburetor. To prevent carburetor
malfunction, service the air cleaner regularly (page 16). Service more
frequently when operating the generator in extremely dusty areas.
WARING! Never use gasoline or low flash point solvents for cleaning
the air cleaner element. A fire or explosion could result.
CAUTION: Never run the generator without the air cleaner. Rapid
engine wear will result.
1. Unsnap the air cleaner cover spring, remove the air cleaner cover
and remove the element.
2. Wash the element in a non-flammable or high flash point solvent
and dry it thoroughly.
3. Soak the element in clean engine oil and squeeze out the excess oil.
4. Reinstall the air cleaner element and the cover.
