3.1 ADD OIL
1. Remove the oil maintenance panel.
2. Unscrew the oil dipstick and wipe it off.
3. Remove the dipstick and ll the oil to the maximum oil mark. Check the oil
level by reinserting the dipstick without rethreading it.
4. Reinsert the dipstick and tighten securely. Replace the oil maintenance
panel and screws.
NOTE
 SAE 10W-30 or SAE Synthetic 5W-30 is recommended for general use.
 Use of synthetic oil does not change maintenance intervals.

 Do not tilt the generator when adding engine oil. This could result in
overlling and damage to the engine.
 Use high quality 4-stroke engine oil, certied to meet or exceed API
standard SG, SF, SAE ratings with strong detergents. Using non-
detergent or 2-stroke oil could shorten the engine’s working life.
 Do not mix different engine oils.
 Handle and store the engine oil with care, avoid getting dirt or dust into
the engine oil.
 Before the engine oil falls below the safety margin, the low oil alert
system will automatically shut off the engine. The low oil light will
turn on.
 To avoid the inconvenience of unexpected engine shutoff, check the oil
level as often as possible.
