Adjustment of the
operating unit
1. Turn main on/off handle 1 to off position A.
2. Set all hand levers on the distribution valve 2 to spraying position A.
3. Put the tractor in neutral and set the engine revolutions and thereby
the number of revolutions of the pump corresponding to the intended
travelling speed. Remember the number of revolutions on the P.T.O.
must be kept between 300-600 r/min.
4. Turn main on/off handle 1 to spraying position B.
5. Now turn the pressure regulating valve 3 to until the required pres-
sure is indicated on the pressure gauge.
6. Operating the control unit while driving:
To close the entire boom, turn the handle 1 to position A. 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 2
of the distribution valve to position B (off position) for the section or
sections to be closed. Note that the pressure will rise and readjustment
will be necessary.
