4.11 FILLING THE TANK

The machines for defensive crop treatments, in consideration of the safety of persons, animals and the protection of the environment, must only be filled indirectly from open water courses and only by free-falling water from the waterworks.

The pipe used for filling must never come into contact with the liquid inside the tank and therefore the water must always fall over the upper edge of the filling inlet and through the filter installed on it.

The tank is fitted with a transparent graduated band that shows the exact quantity of liquid inside. This reading is precise if the tank is on flat ground; the actual total capacity coincides with the highest number. All the filling systems fitted by Unigreen on their production machines or on request are antipollution and stop the liquid overflowing out of the tank.

a)FILLING WITH THE 3-WAY DEVIATOR (Fig. 7).

It is possible to fill the tank using the pump and the floating filter kit G (cod.1002/0080F) with 6 metres of rubber hose (the floating filter lets you always and only suck up clean water).

=connect hose T to deviator D using the union hose adaptor supplied.

=turn the lever of deviator D to the filling position.

=place the other end of the hose, on which you fitted filter G, in the watering point.

=start the power-takeoff leaving pressure regulator C in the draining position (you don’t have to put the pump under pressure).

=the filling speed in litres/minute is equal to the delivery of pump P.

=visually check the level of the liquid in the tank and after filling stop the pump and put the lever of deviator D back in the working position.

=disconnect pipe T from deviator D.

4.12 MIXING

The active principle can be mixed using the relevant stirrers before and during the treatment. Correct mixing and stirring is the basis of the correct distribution on the crops. We recommend some useful accessories such as the premixer for powders and liquids (see the following paragraph).

To mix the product in the tank proceed as follows:

a)high-pressure machines from 30 to 60 bar (FIG. N° 8a): run the stirrer (RED tap) or the ejector (GREEN tap) for roughly 10-15 minutes at the maximum pressure available

b)low pressure machines, max 20 bar

=with a drilled pipe on the drain, run the pump at roughly 540 RPM with the pressure regulator on drain for at least 10-15 minutes. (FIG. N° 8b)

=with the stirrer on a delivery, run the pump supplying the stirrer (or ejector) at the maximum pressure available for at least 10-15 minutes. (FIG. N° 7)

WARNING: using the taps on the pump or in any case on the front of the machine puts the operator near the cardan shaft. Despite the presence of protections at CE rule, it is compulsory to switch off the engine and to take the key off.

4.12.1MANUAL PREMIXING

Dilute the active principle by hand before introducing it into the tank, (you must wear suitable protective clothing such as rubber gloves, a mask or goggles, overalls, etc.).

4.12.2PREMIXER ON COVER (OPTIONAL):

Open the cover and pour all of the chemical powder into the filter, close the cover and open the supply tap until all of the powder has dissolved.
