CHECKING/ADDING OIL
Check the oil level before each use and every 8 hours of operation (refer to Fig. 14). 
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 screwing in. Remove the 
dipstick to check the oil mark (Fig. 16). Add oil if the oil mark covers less than 
one half of the dipstick. 
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.

MAINTENANCE
DRAINING/CHANGING OIL
Change the oil according to the Recommended Maintenance Schedule in 
Fig. 14. 
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-storage 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. 17) and allow oil to drain from the engine completely.
3. Reinstall the oil drain bolt and tighten it securely. Wipe clean any oil spillage.
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.
