Freedom 38 PPA Service Manual 809010 31
1 – Troubleshooting
Use the hand pump to bleed the fuel system
You may have trouble starting the engine if:
 The fuel level in the engine is very low.
 You recently worked on some part of the fuel system.
 The system has not been used for a long period of time.
If you have trouble starting the engine, use the hand pump to bleed the fuel system.

If you frequently need to bleed the fuel system in order to start the engine, this may
indicate an air leak in the fuel line. Have an authorized Hypertherm Freedom 38 PPA repair
facility examine the fuel supply lines, or have an authorized Deutz service dealer examine
the engine.
1. Turn OFF the system.
2. Remove the service panel on the generator
side of the system.
3. Push in the hand pump several times in
quick succession until you feel a resistance
and until you no longer hear fuel moving
through the fuel supply lines.
4. Start the engine, but leave the main circuit
breaker and the transformer circuit breaker
off. Run the engine without load for 2–3
minutes. This allows air to return to the fuel
tank via the return fuel line.
5. Put the service panel back in place.
