PRE-OPERATION CHECK
Be sure to check the generator on a level surface with the engine stopped.
4.1 Check the engine oil level
Using non-detergent oil or 2-stroke engine oil could shorten the engine’s service life.
3

Use high-detergent, premium quality 4 –stroke engine oil, certified to meet or exceed
U.S. automobile manufacturer’s requirements for API Service Classification SG.
SF.(15W40)
Select the appropriate viscosity for the average temperature in your area.
Ambient Temperature
Loosen the cover screw and remove the left side maintenance cover. Remove the oil
filer cap, and wipe the dipstick with a clean rag. Check the oil level by inserting the
dipstick in the filler hole without screwing it in..
If the oil level is below the end of the dipstick, refill the recommended oil up to the top
of the oil filer neck.
The Oil Alert System will automatically stop the engine before the oil level
falls below the safe limit. However, to avoid the inconvenience of an
unexpected shutdown, it is still advisable to visually inspect the oil level
regularly.
