Maintenance Information:
Inspect the air filter at the interval specified in the generator owner’s manual. Replace it whenever it becomes excessively dirty, wet, damaged, or restricted. Generators operating in dusty or demanding environments may require more frequent replacement.
Turn the generator off and allow the engine to cool before servicing it. Remove loose debris from around the air-filter housing and ensure the replacement filter is seated properly before reinstalling the cover.
Verify the generator model number, serial number, engine size, and existing air-filter part number before ordering.
