7. Note the pressure and place the first lever 3 on the distribution valve
in position B (off position).
8. Turn the corresponding adjust screw 5 until the pressure gauge
again shows the same pressure (turn the screw clockwise for higher
pressure, anti-clockwise for lower pressure).
9. Adjust the other sections of the distribution valve in the same way.
NB: HEREAFTER ADJUSTMENT OF PRESSURE EQUALIZATION
WILL ONLY BE NEEDED IF YOU CHANGE TO NOZZLES WITH
OTHER CAPACITIES.
10. Operating the control unit while driving:
To close the entire boom, turn the handle 2 to position B. This takes
the pressure off the pump. The liquid will then return to the tank via the
return system. The diaphragm anti-drip valves ensure instantaneous
closing of all nozzles. In order to close part of the boom, move lever 3
of the distribution valve to position B (off position) for the section or
sections to be closed. The pressure equalization device ensures that
the pressure does not rise in the sections which are to remain open.
Drain valve operation
