Generac generally recommends maintenance every 200 operating hours or two years, whichever occurs first. More frequent service may be required in dusty, dirty, or demanding operating conditions. Always follow the maintenance schedule in the owner’s manual.
Verify compatibility using the generator’s complete model number, serial number, engine displacement, and production date before ordering. Disable automatic starting, disconnect the battery as directed, and allow the engine to cool before performing maintenance.
