CHECK AIR FILTER
A dirty air filter will restrict air flow into the carburetor,
will cause poor fuel economy, and may damage the en-
gine. To keep the generator in good operating condition,
service the air filter regularly. Service more frequently
when operating the generator in extremely dusty areas.
Note: Never operate the generator without the air filter
in place. Operating the generator without the air
filter in place will result in rapid engine wear.
Open the left service door (1). Remove the air filter cover
bolt (2) and remove the air filter cover (3) by lifting out
the service door opening. Make sure that the air filter is
clean and not damaged. If the air filter is dirty, wash the
filter. If the air filter is damaged, replace the air filter.
Use a nonflammable solvent or a mixture of household
detergent and warm water to wash the filter. Rinse the
filter thoroughly to remove all of the cleaning solution.
After the filter has dried, pour a small amount of en-
gine oil into the filter and squeeze to distribute the oil
throughout. Remove excess oil and replace the filter.
Note: Do not wring out the filter. Wringing out the filter
may damage the filter.
Use a damp rag to wipe dirt from the case and cover.
Install the filter into the housing. Place the air filter cover
over the filter and reinstall the air filter cover bolt. Rein-
stall the service door.
