5.2.1 Engine oil
Ensure that the generator is on level ground before checking
engine oil level. Install the oil dipstick all the way in.
The appropriate level should be between the lower limit and
upper limit on the dipstick.

Add engine oil if the level is below the lower limit.

Select the appropriate engine oil.

Open the access door, remove oil cap.
Add engine oil to bring oil level NO higher than FULL
mark on the dipstick.

Tighten the oil inlet cap and close the access door.
CAUTION:

If the generator is not level when checking the engine oil, you cannot obtain an
accurate oil level reading.

Do not overfill the engine oil. The level cannot exceed the upper limit. An excessive
amount of engine oil may damage the engine.

Do not smoke and extinguish any naked flames before adding engine oil.
