Fire hazard. Never use gasoline or other flammable

The air filter must be cleaned after every 50 hours of use or
six months (frequency should be increased if the generator
is operated in a dusty environment).
1. Place the generator on a level surface and allow the
engine to cool for several minutes.
2. Remove the engine service cover.
3. Turn the knobs on the air cleaner cover to the unlocked
position. Tip the cover down to remove.
Note: The air filter element is oil soaked. Use an
appropriate cleaning container.
Avoid skin contact with engine oil. Wear protective
clothing and equipment. Wash all exposed skin with
soap and water.
