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 generator in extremely dusty
areas.
Do not use gasoline or low flash point solvents for cleaning. They
are flammable and explosive under certain conditions.
Never run the generator without the air cleaner. Rapid engine wear
may result.
1. Loosen the cover screws and remove the air cleaner cover.
