C.4.1 Ventilating the Fuel System
Normally, the fuel system is designed to ventilate air itself i.e. as soon as the electric starter motor
starts operation the fuel pump starts working and the fuel system will be de-aerated after some
time automatically. It is nevertheless essential to ventilate the system as follows prior to the first
operation (as all hoses are empty):
1. Main power switch "OFF"
2. Press failure bypass switch and keep
firmly pressed. The electrical fuel
pump must be audible. Switching on
and off the solenoid valve at the gene-
rator will be audible by pressing the
failure bypass switch (if capsule remo-
ved).

3. Pressing the failure bypass switch for
approx 3 - 4 minutes will loosen the
ventilation screw located at the fuel
solenoid valve. The button must conti-
nue to be pressed, whilst opening the
screw. A large cloth or Kleenex tissue
must be laid beneath the connection to
prevent escaping fuel running into the
capsule. If the fuel runs out without air
bubbles, then the ventilation screw can
be closed. Only then may the button
be released.
