Checking Engine Oil Level
The oil level should be checked daily when power
outages necessitate running the generator for extended
periods. Proceed as follows to check the engine oil level:
1. Run the generator for a cool-down period of
approximately one minute.
2. Turn the main utility disconnect off.
3. Turn the main line circuit breaker (MLCB)
(generator disconnect) on the generator to OFF
(OPEN).
4. Turn the generator off.
5. Press the control panel OFF button. Wait five
minutes.
6. Remove the oil dipstick and wipe it dry with a clean
cloth.
7. Completely insert the oil dipstick into the oil dipstick
tube and remove it.
8. Observe the oil level. The level should be at the
“FULL” mark on the oil dipstick.
9. If necessary, remove the oil fill cap and add oil to
the engine (with the oil dipstick removed) until the
level reaches the “FULL” mark and insert the oil
dipstick and fill cap.
To restart the generator:
1. Press the control panel AUTO button.
2. Allow the generator to start and warm up for a few
minutes.
3. Set the generator disconnect on the generator to
ON (CLOSED).
4. The system is now operating in automatic mode.
The main utility disconnect can be turned ON
(CLOSED).
