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):
Attention:
Generators with iControl system do not need a Failure
bypass switch. At these generators the fuel pump can be
activated by an option of the control panel. See Control
panel manual.
1. Main power switch „OFF“
Fig. 7.9-1: Failure bypass switch
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 generator will be audible
by pressing the failure bypass switch (if capsule
removed).
Note!
Generators with iControl system has no failure bypass
switch. The Fuel pump can be activated at the iControl panel.
Please see iControl manual for details.

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 continue 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.
Use spanner size 10 mm.
Note!:
Not all generator models has a fuel solenoid valve. At
generators without fuel solenoid valve, a single ventilation
screw is installed.
