Changing Engine Oil
Drain the oil while the engine is still warm to assure rapid and complete drainage.
1. Remove the oil dipstick and wipe the oil dipstick with a clean rag.
2. Remove the drain bolt and drain the oil into a suitable container.
There is a rubber plug in the bottom of the generator pan to facilitate draining
the oil. The generator will have to be raised off the ground while the oil drains.
3. Retighten the drain bolt securely.
4. Refill with the recommended oil.
5. Insert the dipstick in the filler hole – and fully screw it in.
6. Unscrew, remove and carefully read the oil level.
7. Add oil if necessary until the oil level is at the top of the dipstick marking.
8. Reinstall the dipstick, securely screwing it until tight.
Dispose of used motor oil in a responsible manner. Do not throw it in the trash or pour it on the
ground.
Air Cleaner Service
A dirty air cleaner will restrict airflow to the carburetor and allow dirt into the engine. Service more
frequently when operating the generator in extremely dusty areas.
Never run the generator without the air cleaner. Rapid engine wear may
result.
