Setting of the pressure
Unscrew the screw of the PO pressure intake of the gas valve before the nozzle (pictures 1.A
and 1.B), and connect a water column manometer. Feed the modulator and take out the
yellow tap of the pressure regulator. Act, as shown in picture 2, on the CH10 screw for setting
of the maximum pressure, till you get the required pressure (turn clockwise to increase
and counter clockwise to decrease). Take out tension at the pressure modulator, and with
a screw-driver act on the inner screw for minimum setting (picture 3) till you get the required
pressure (turn clockwise to increase and counter clockwise to decrease).
