Adjustment of operating unit M70

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
pressure 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.

Adjustment of operating unit SV/2

This high-pressure electric operating unit can be assembled with piston
or diaphragm pumps.
It consists of a manual pressure valve that has a pressure gauge. To raise
the pressure, turn the red handle A clockwise. To lower it, turn it anti-
clockwise.
The two section valves are remote controlled by two solenoid valves
activated via a control box in the tractor cabin.

Adjustment of operating unit BS/2

This high-pressure manual operating unit can be used with piston or
diaphragm pumps.
To raise the pressure, turn the black handle. To raise the pressure, turn
the handle clockwise. To lower it, turn it anti-clockwise.
The direction of the flow can be selected with the control.
The different positions are embossed on the lever.
R = Free return
C = Agitation only
1 = One open spray zone + active agitation
2 = Two open spray zones + active agitation

WARNING! As this operating unit is assembled on the tractor
beside the operator, ensure that there is no leakage as otherwise
your safety may be at risk.
