between the High and Low marks.
The generator set is shipped with 0W30 synthetic engine oil. Refer to the Model
Specification section for the oil specification.
Checking Engine Oil Level
WARNING
State and federal agencies have determined that contact with used engine oil
can cause cancer or reproductive toxicity. Avoid skin contact and breathing
of vapors. Use rubber gloves and wash exposed skin.

Accidental or remote starting of the generator set can cause severe personal
injury or death.
The generator set must be off and locked out of service whenever the air
inlet, air outlet, or any interior panels, are removed.
WARNING
Crankcase pressure can blow out hot oil and cause severe burns. Do NOT
check oil while the generator set is operating.
NOTICE
Check the engine oil level when the generator set is not running and is out
of Remote mode.
