  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.

  Samuel BishopAug 20, 2025
  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. Also, check the connecting cord for any damage and repair if needed. Try connecting another device that is in good condition to ensure that the initial device is not the problem. If none of these steps work, there may be a fault in the generator, and you should contact an authorized service facility.

  If your Firman Portable Generator engine shuts down while running, check if it is out of gasoline or LPG/NG and refill or replace the fuel source. Ensure that the air cleaner is not dirty by cleaning or replacing it. Also, verify that the oil level is sufficient and add oil if needed, making sure the generator is on a level surface.

  If your Firman Portable Generator engine “hunts” or falters, it could be due to a carburetor issue (running too rich or lean), requiring you to contact an authorized service facility. Another potential cause is a clogged or dirty fuel filter, so try cleaning or replacing it.
