  If your Firman Portable Generator engine will not start, starts and runs rough, or shuts down, make sure the engine switch is in the ON position and the fuel shutoff lever is also in the ON position. Check the oil level and add oil if it's low, or place the generator on a level surface. Inspect the air cleaner and replace it if it's dirty. Ensure there is fuel in the tank, and if the fuel is stale, drain and replace it with fresh fuel. Verify the spark plug wire is connected, and replace the spark plug if it's bad. If the engine is flooded, wait 5 minutes before re-cranking. If equipped with a starting battery, ensure it has sufficient charge.

  If your Firman Portable Generator's engine is running but there's no AC output, first, try resetting the circuit breaker. Also, check for and repair any poor connections or defective cord sets. Ensure the device you're connecting is in good working order by testing with another device. If these steps don't resolve the issue, it may indicate a fault within the generator itself, requiring assistance from an authorized service facility.
