| Code | Meaning | What to do | Manual page |
|---|---|---|---|
| CO alarm light | Lights red when the carbon monoxide concentration exceeds the standard. The generator stops soon after. | Move to fresh air right away if you feel sick, dizzy or weak, and see a doctor. Only operate the generator outside and far away from windows, doors and vents. Use a battery-powered or battery-backup CO alarm in the home. | 9 |
| CO failure light | Lights yellow when the CO sensor is broken. | The manual gives no specific action for this light. | 9 |
| Oil warning light | Low oil alarm. The system shuts down the engine before crankcase oil drops to an unsafe level, and the light stays on if you try to restart without enough oil. | Fill the engine with the recommended oil to the upper limit (H), then restart the generator. Check the oil level regularly. | 9 |
| Overload | The generating set is overloaded and the AC protector stops the output to protect the equipment. The engine keeps running. The light may also come on briefly when a motor starts and should go off within about 4 seconds. | Disconnect the electrical equipment first. Reduce the loads, then press the reset button to restore output. If the red light stays on and the green running light is not on, shut down the engine and check for a malfunction. | 9 |

Starting surge matters more than running watts: this unit is rated 2500 W output (no separate peak published). That covers a typical 1/2 HP sump pump (about 2150 W to start). Use the calculator with your exact pump.
