Checking the Oil Level 

 
It is important to check the oil level in the engine crankcase before each use to ensure that there is a sufficient quantity. 
 
To check the oil level: 
1. Verify that this generator is shut down and on a level surface. 

2. Unscrew the oil filler/dipstick cap from the engine. 

3. With a dry cloth, wipe the oil off of the dipstick that is located on the inside of the cap. 

4. Insert the dipstick as if replacing the cap and then remove again. There should be oil on the dipstick. If there is no oil on the dipstick, or oil is 

visible only at the very end of the dipstick, add oil until the engine crankcase is filled. 

5. Confirm that the oil filler/dipstick cap is properly in place when finished verifying the oil level.

 

 

Changing/Adding Oil 

 

The oil level in this generator should be checked before each use. When the oil level is low, add oil until the level is sufficient to operate this 
generator. (See Figure 8B) 
 

The oil should be changed after the first 20 hours of operation. Subsequently, the oil should be changed every 6 months, or for every 100 hours of 
use, or when the oil has become contaminated with water and/or dirt. 

 
To drain the oil from this generator: 
1. Place a bucket underneath this generator to catch oil as it drains. 

2. Unscrew the oil drain plug located on the crankcase underneath the oil filler/dipstick cap using 12 mm hex wrench. Figure 8A 

3. Allow all the oil to drain from this generator. 

4. Replace the oil drain plug and tighten using 12 mm hex wrench. 
 

NOTE: Never dispose of used motor oil in the trash, down a drain or on the ground. Put oil in a sealed container and contact your local 
recycling center or auto garage to arrange oil disposal. 

 

THIS GENERATOR REQUIRES AT LEAST 18.5 OUNCES OF OIL (SAE10W-30) TO RUN.  
 
ADD OIL UNTIL IT IS ALMOST OVERFLOWING. THE LOW-OIL SENSOR IS VERY SENSITIVE AND THE ENGINE 

WILL NOT RUN IF THE OIL IS LOW. START WITH 18.5 OUNCES, THEN ADD MORE UNTIL ALMOST OVERFLOWING. 
 
TROUBLESHOOTING: IF THE GENERATOR WILL NOT START, DOUBLE CHECK THAT THE OIL LEVEL IS 
COMPLETELY FULL AND ALMOST OVERFLOWING.
