surfaces.
WARNING
Hot Engines
Contact with hot engines can cause severe burns. Ensure that the generator
set engine has cooled down before adding or draining the oil.
NOTICE
Too much oil can cause high oil consumption. Too little oil can cause severe
engine damage. Keep the oil level between the High and Low marks on the

Adding Oil
If the oil level is found to be insufficient, oil must be added.

the engine.

Refer to the Checking Engine Oil Level section and the Model
Specifications section.
3. Recheck the engine oil level. Based on the results, add or drain oil.

NOTICE
Refer to local regulations to determine the appropriate container for
used oil.
3. Open the oil drain cap at the end of the hose and the drain valve at the
engine to release oil from the engine into the appropriate container.
