Pre-Operation Check - Honda EB4000 Owner's Manual

3. PRE-OPERATION CHECK
CAUTION: Be sure to check the generator on a level surface with the engine
stopped.
1. Check the engine oil level,
CAUTION: Engine oil is major factor affecting engine performance and
service life. Non-detergent or vegetable oils are not recommended.
Use Honda 4-stroke oil, or an equivalent high detergent, premium quality
motor oil certified to meet or exceed U.S. automobile manufacturer's
requirements for Service Classification SE or SF. (Motor oils classified SE
or SF will show this designation on the container.)
SAE low-40 is recommended for general, all-temperature use. If single
viscosity oil is used, select the appropriate viscosity for the average
temperature in your area.
Remove the oil filler cap and check the oil level.
If the level is low, fill to the top of the oil filler neck with the recom-
mended oil.
CAUTION: Running the engine with insufficient oil can cause serious
engine damage.
