MAINTENANCE
CHANGING / DRAINING THE OIL
Change the oil according to the Recommended Maintenance Schedule. Changing the oil when the engine is warm
allows for complete drainage. Change the oil more often if operating under heavy load or high ambient tempera-
tures. It is also necessary to drain the oil from the crankcase if it has become contaminated with water or dirt. The
oil capacity of the generator engine is 17 fluid ounces. Add oil when the oil level is low. For proper type and weight
of oil refer to “add oil” portion of the “Generator Preparation” section. Drain the oil from the generator according to
the following steps after removing the side panel.
1. Place a container underneath the engine to catch the oil as it drains.
2. Using a 10 mm hex wrench, unscrew the oil drain plug (Fig. 14). Allow the oil to drain from the engine.
3. Reinstall the oil drain plug and tighten with a 10 mm hex wrench.
TO REFILL THE OIL
1. Make sure the generator is on a level surface. Tilting the generator to assist in filling will cause oil to flow into
engine areas and will cause damage. Keep generator level!
2. Remove the dipstick from the engine.
3. Using a funnel or appropriate dispenser, add the correct amount of oil into the crankcase. The engine is equipped
with a low oil pressure sensor and will not start if the amount of oil is insufficient.
4. The oil is full when it reaches halfway up the threads of the dipstick (oil upper level fill line - Fig. 14). Reinstall
dipstick.
NOTE: Never dispose of used motor oil in the trash or down a drain. Please call a local recycling center or auto
garage to arrange oil disposal.
