CHECKING/ADDING OIL

Check the oil level before each use and every 8 hours of operation.

The oil capacity of the generator engine is 37.2 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. Clean around the oil ﬁll. Remove the dipstick and wipe the it with a clean rag.

3. Insert the dipstick into the oil ﬁll opening without screw-

ing in. Remove the dipstick to check the oil mark (Fig. 15).

Add oil if the oil mark covers less than one half of the dip-

stick.

4. Using a funnel or appropriate dispenser, slowly add more

oil. Repeat step 3 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.

5. Reinstall dipstick and wipe clean any spilled oil with a rag.

Reinstall the oil access cover.

DRAINING/CHANGING OIL

Change the oil according to the Recommended Maintenance Schedule.

Change the oil more often if operating under heavy load or high ambient

temperatures. It is also necessary 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. Prepare an approved gasoline-stor-

age container underneath the oil drain bolt next to the oil dipstick to catch

the oil as it drains.

2. Unscrew the oil drain bolt (Fig. 16) and allow oil to drain from the engine

completely.

3. Reinstall the oil drain bolt and tighten it securely. Wipe clean any oil spill-

age.

NOTE: Never dispose of used engine oil in the trash or down a drain. Please

call a local recycling center or auto garage to arrange proper oil disposal.
