3.5.2 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. Disconnect the negative (-) battery cable and place the control switch in its OFF
position before starting work.

2. Reinsert the dip stick
3. Remove the dipstick one final time and check the oil level

marks.

If the engine oil level check shows excessive or insufficient levels of oil (oil level line above the
FULL mark or below the ADD mark), oil must be drained or added. Refer to the following
sections (Drain Oil or Add Oil - as needed) for instructions and guidelines for draining and
adding oil.

Too much oil can cause high oil consumption. Too little oil can cause severe engine
damage. Keep the oil level between the FULL and ADD marks on the dipstick.

If the oil level is found to be excessive (see Checking Engine Oil Level), oil must be drained
from the engine.
