Error codes and troubleshooting
| Code | Meaning | What to do | Manual page |
|---|---|---|---|
| Circuit Breakers | The receptacles are protected by an AC circuit protector that trips if the generator is overloaded or an external short circuit occurs. | Disconnect all electrical loads and determine the cause before using the generator again. If overloading caused the trip, reduce the load. Reset by pressing the protector button. Continuous tripping may damage the generator or equipment. | 8 |
| Oil Warning Indicator Light | Indicates the oil has fallen below the minimum level. The engine stops automatically and will not start until the proper amount of oil is in the crankcase. | Check the oil level when this light turns on. Add the proper amount of engine oil to the crankcase before attempting to start the engine. | 8 |
| Overload Indicator Light | Connected devices have exceeded the generator's wattage or amperage capacity, or a power surge occurred. The AC Power light goes off, the engine keeps running, and power to the receptacles is cut. | Keep the total power drawn from all receptacles within the nameplate rating. | 8 |
| Circuit Breaker | The receptacles are protected by an AC circuit protector that trips if the generator is overloaded or an external short circuit occurs. | Disconnect all electrical loads and find the cause before using the generator again. If overloading caused the trip, reduce the load. Reset by pressing the button on the protector. Continuous tripping may damage the generator or equipment. | 9 |
| Output Ready | Stays on during normal operation. Turns off when the generator is overloaded. | — | 9 |

FAQ
How long does the Firman T09371 run on a tank?
The maker rates it at 11 hours at 50 % load (about 4,650 W) on a 9.0-gal tank. A light load such as a refrigerator and lights runs longer; a full load runs shorter.
Can the Firman T09371 start a sump pump or well pump?
Starting surge matters more than running watts: this unit is rated 11600 W peak. That covers a typical 1/2 HP sump pump (about 2150 W to start). Use the calculator with your exact pump.
