Possible Causes
Insufficient oil in crankcase, Faulty oil level sensor, Sensor wiring harness damage, Excessive engine oil consumption
How to Fix / Troubleshooting
Safety first: Turn generator OFF, open main breaker, and allow engine to cool.
- Check oil level: Use the dipstick to verify oil level. Add Kohler-approved oil to bring level to the FULL mark.
- Inspect for leaks: Look for oil leaks at the filter, drain plug, and gaskets. Repair leaks before further operation.
- Sensor and wiring: Locate the oil level sensor (often in the oil pan). Inspect connector and wiring for damage. Clean and reseat.
- Monitor consumption: After topping up, run the unit and recheck oil level after several hours of operation. Rapid loss indicates internal engine issues requiring professional service.
Do not bypass the oil level sensor; it protects the engine from damage.
