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.
m 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 may result.
1. Unsnap the clips, remove the air cleaner cover and remove the element.
