Error codes and troubleshooting
| Code | Meaning | What to do | Manual page |
|---|---|---|---|
| FLASHING RED LIGHT | Dangerous levels of carbon monoxide gas have built up and the generator shuts off. | Leave the area immediately until it has aired out. Move the generator to a well-ventilated area before operating it again. | 5 |
| FLASHING YELLOW LIGHT | The carbon monoxide sensor is malfunctioning and needs service. The generator should not be used until the sensor works properly. | Do not use the generator until the sensor is working properly. Call Harbor Freight technical support at 1-888-830-0321. Only a qualified technician may service the CO sensor. Do not modify or tamper with it. Call service if it persists. | 5 |
| LOW OIL | The engine shuts off if the engine oil level is too low. The engine will not start with low or no engine oil. | Stop the engine and make sure the generator is level. Check the dipstick oil level and add the appropriate oil until it reaches the proper level. SAE 10W-30 is recommended for general use. Reinstall the dipstick and access panel. | 11 |
| OVERLOAD | The OVERLOAD light turns on and the generator stops producing power when the total connected load exceeds the unit's running power. | Disconnect all electrical devices and compare their requirements to the generator rating. Move anything blocking generator ventilation. Press the Overload Reset button below the 120VAC receptacle so the OVERLOAD light turns off. Reconnect devices carefully, without overloading the generator. | 15 |
| Carbon Monoxide level high | The generator is overloaded, so the attached device has no power or the rated load capacity has been exceeded. | Turn off and unplug the device(s), press the circuit overload reset button, then plug the device(s) back in and turn on. Reduce the number of items plugged in or use a more powerful generator. | 19 |
| CO Sensor Alarm | Carbon monoxide level is high. The red CO sensor light illuminates, and the yellow CO Sensor Alarm may flash continually shortly after starting or after longer operation. The engine stops suddenly. | Leave the area immediately and ventilate thoroughly. Operate the generator only outdoors, keep at least 5 ft clearance on all sides, and stay within the rated ambient temperature. If the sensor needs service, call 1-800-444-3353 as soon as possible and do not use the generator until the sensor works properly. Call service if it persists. | 24 |

FAQ
Can the Predator 3500 Watt Super Quiet Inverter start a sump pump or well pump?
Starting surge matters more than running watts: this unit is rated 3500 W peak. That covers a typical 1/2 HP sump pump (about 2150 W to start). Use the calculator with your exact pump.
