maintain proper engine oil level could result in severe 

damage to the engine and/or shorten the life of the 

engine. Always use the specified engine oil. Failure 

to use the specified engine oil can cause accelerated 

wear and/or shorten the life of the engine.

Engine oil level should be checked before every use.

1. 

Always operate or maintain the generator

on a flat surface.

2.  Stop engine if running.
3. 

Let engine sit and cool for several minutes (allow 

crankcase pressure to equalize).

4. 

With a damp rag, clean around the

remove the oil fill plug/dipstick and wipe it clean. 

Thread the oil fill plug/dipstick all the way back in and 

then remove and check the oil level on the oil fill plug/

dipstick. 

•  Acceptable Oil Level

 – Oil is visible on the 

crosshatches between the H and L lines on the oil 

fill plug/dipstick (see Figure 20).

If oil level is below 

this line it is too
