MAINTENANCE
CHECKING/ADDING OIL
Check the oil level before each use and every 8 hours of operation (refer to Fig. 11).
The oil capacity of the generator engine is 13.5 fl. 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. This is a
critical step for proper engine starting. The generator is equipped with an automatic shutoff to protect it
from running on low oil.
To check the oil level and add oil:
1. Make sure the generator is on a level surface. Do not tilt the generator, as oil will flow into engine
areas and cause damage. Keep generator level!
2. Remove the dipstick (Fig. 13) and wipe
it with a clean rag.
3. Insert the dipstick into the oil fill open-
ing without screwing in. Remove the
dipstick to check the oil mark. Add oil if
the oil mark covers less than one half of
the dipstick.
4. Using a funnel or appropriate dis-
penser, slowly add more oil. Repeat step
2 until the oil mark reaches the top of the
dipstick (you can see oil coming up the
threads of the oil fill). Do not over fill.
DRAINING THE OIL
Change the oil according to the Recommended Maintenance Schedule in Fig. 11.
Change the oil MORE OFTEN if operating under heavy load or high ambient temperatures. It is also nec-
essary to drain the oil from the crankcase if it has become contaminated with water or dirt. Changing the
oil when the engine is warm allows for complete drainage.
To drain the oil from the generator:
1. Place generator on elevated platform such as table or desk. Prepare a container underneath the oil
drain plug next to the oil dipstick to catch the oil as it drains.
2. Unscrew oil drain plug (Fig. 13) and allow the oil to drain from the engine completely.
3. Reinstall the oil drain plug and tighten it securely. Wipe clean any oil spillage.
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 proper oil disposal.
5. Reinstall dipstick and wipe clean any spilled oil with a rag.
