OTHER CAPACITIES.
11.Operating the control unit while driving:
In order to close the entire boom switch on-off A to off position. This
returns the pump output to the tank through the return system. The
diaphragm anti-drip valves ensure instantaneous closing of all
nozzles.
In order to close one or more sections of the boom, switch the
relevant distribution valve V to off position. The pressure equaliza-
tion ensures that the pressure does not rise in the sections which
are to remain open.
In case of power failure it is still possible to activate all functions of the
operating unit. See section “Emergency operation of the sprayer”.
When the sprayer is put aside, the control box and the multiplug must
be protected against moisture and dirt. A plastic bag may be used to
protect the multi plug.
Operation of the tank drain valve
Pull the red handle on the side of the tank to open the drain valve. The
valve is spring-loaded, but can be kept open by pulling the string out
and upwards in the V-shaped slit. To release, pull the string down-
wards and the valve will close automatically.
