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.

4. Pressing the starter button can now start the machine.
The machine should start after a short period.
5. If this does not occur, then a connecting nut fitted to the
injection line must be loosened and starting procedure
repeated. Retighten the washers after successfully
starting. The injection line must be raised by several
millimetres.
Use spanner size 17 mm.
6. Switch main switch „OFF“.
9.13.1 Replacement of the fuel filter
Fig. 9.13.1-1: Fuel Filter
Exchanging the filter, depending upon fuel contamination,
should take place after 300 operational hours at the very
least. The inlet must be clamped, before exchanging the
filter.
Remove the hoses from the used filter and fasten them to the
new filter. The arrow on the filter housing indicates the
direction of the fuel flow. A clogged filter causes a decreased
power output of the generator.
