  If your Firman Portable Generator's engine is running fine without any load but struggles or 'bogs down' when you connect devices, it could be due to a few reasons. First, there might be a short circuit in the connected device, so try disconnecting it. Alternatively, the fuel filter might be clogged or dirty, in which case you should clean or replace it. If these steps don't resolve the issue, it's possible that the engine speed is too slow or there's a shorted generator circuit, requiring you to contact an authorized service facility.

  If your Firman Portable Generator's engine is running but there's no AC output, start by checking the circuit breaker and reset it if it's open.
