Maintenance Information:
Inspect the air filter according to the generator owner’s manual. Replace it whenever it becomes excessively dirty, damaged, wet, or restricted. Generators operating in dusty or demanding environments may require more frequent replacement.
Verify the generator model number, serial number, engine size, and existing air-filter part number before ordering.
