Bleeding the fuel system
Bleed the fuel system in the following cases:
• After removing and fitting the fuel filter, prefilter or the fuel lines back
on again
• After running the fuel tank empty
• If the machine is put into operation after having been decommissioned
for more than 30 days.
Bleed the fuel system as follows:
1. Raise the control lever base.
2. Remove the starting key.
3. Fill up and close the fuel tank.
4. Turn the starting key to the first position.
5. Wait about 5 minutes while the fuel system bleeds itself automatically.
6. Start the engine.
If the engine runs smoothly for a while and then stops, or if it does not run
smoothly:
1. Stop the engine.
2. Raise the control lever base.
3. Remove the starting key and carry it with you.
4. Bleed the fuel system again as described above.
5. Check for leaks after starting the engine.
6. Have a Wacker Neuson service center perform a check if necessary.
