(3) goes out automatically and the fuel feed pump stops.
When lamp (3) goes out, air bleeding is completed.

If the fuel circuit is empty after the machine stops because
of running out of fuel, or the fuel hose and tubes are serv-
iced, or the supply pump is replaced, perform the following
procedure.
1)

position again.

Check that lamp (3) has gone out.
5.
