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 CE standard protective covers you should take great care.

4.10 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 SUCTION FILTER (Fig. 10 - Fig. 11).

If the 3-way deviator isn’t fitted you can fill the tank using the coupling on the cover of the suction filter. Unscrew the rear wing nut of the filter and using a G1"1/2 threaded union, connect pipe T with the floating filter to the coupling. Also in this case the filling speed in litres/minute is equal to the delivery of the pump.

b)FILLING WITH THE ANTIPOLLUTION EJECTOR (Fig. 12)

If you are filling with an antipollution hydroejector (mounted as standard on some models) then you should proceed as follows:

=put roughly 20-30 L of water in the tank and start the pump.

=remove the cap of ejector E and insert filling pipe T.

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

=open the tap that supplies the ejector (on pump P or pressure regulator C).

=increase the pressure until it reaches a value which is sufficient to suck up the liquid.

=visually check the level of the liquid inside the tank and after filling disconnect pipe T from the ejector, close the tap and replace the cap.

4.11 TEST WITH CLEAN WATER

It is good practice to do a test with clean water (without chemical product in the tank) before the first treatment to make sure the atomiser is working properly and to get to know the controls. For instructions on how to proceed with the treatment see the chapter SPRAYING.

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:
