  If your Firman Portable Generator's engine runs fine without any load but struggles or stalls when you connect devices, it could be due to several reasons. There might be a short circuit in the connected device, so disconnect it. Alternatively, the fuel filter might be clogged or dirty, requiring cleaning or replacement. In some cases, the generator might be overloaded. If none of these resolve the issue, there could be a shorted generator circuit or an engine speed problem, requiring assistance from an authorized service facility.

  If your Firman Portable Generator engine is running, but there's no AC output, start by checking the circuit breaker and resetting it if it's open. Ensure the cord set is in good condition. If the problem persists, try connecting a different device to rule out issues with the original device. If none of these steps work, it could indicate a fault within the generator itself, requiring assistance from an authorized service facility.
