Filling with Crop Protection Chemicals

IMPORTANT: Before adding the crop protection chemicals, first read the safety instructions on the label or package.

When preparing the spraying liquid, be sure to distribute the chemicals evenly over the total quantity of liquid. There must not be any undissolved residues in the tank. Intensive agitation is essential. If various chemicals are sprayed simultaneously, always start with the poorly dissolving chemicals, followed by the more soluble ones.

The chemicals can be added via the filling hole, the chemical inductor or with a stationary chemical inductor. Always put the chemicals into the tank with the agitation device activated.

Fill the tank with water and during filling add the crop protection chemicals via the filling hole and the basket strainer.

In the case of liquid chemicals, we recommend to gradually pour the chemical into the tank during filling. The quantity required can be measured very easily. If there is no graduation on the barrel, measure the correct quantity with a measuring jug. When using powdered chemicals, prepare the solution in a bucket in advance and gradually pour this onto the basket strainer during filling.

Fill the solution tank with clean water by means of the pump, with valve (A) in position (C), until it is filled to approximately one quarter. Turn the pressure selection valve (A) to "Chemical inductor / Rinsing head" position (B).

Operate the ring line by opening (adjustable) shut-off valve (F) on the ring line.

Adjust the injector with shut-off valve (F) so that it sucks just as much liquid as the amount of water transported to the chemical inductor by the ring line when the water level is above the sieve plate and add the crop protection chemicals to the chemical inductor. The dissolved crop protection chemicals from the cistern are sucked in by the injector and transported to the tank through the basket strainer. The inadequately dissolved elements remain behind on the sieving plate until they are sufficiently dissolved to be sucked in.

In the case of chemicals which are hard to dissolve, proceed as follows:

Have the pump operate at half speed, in order to prevent the tank already being full before all crop protection chemicals have been dissolved and/or barrels have been flushed. If the chemicals in the inductor have not been completely dissolved, temporarily deactivate the injector until the chemicals are dissolved. After this, restart the injector. When the chemical inductor is flushed completely and the crop protection chemicals have been inserted, close the shut-off valves on the injector and the ring line.

Top up the solution tank with water to the required level, which can be read from the dry liquid level indicator of solution tank. To this end, set the pressure selection valve to "pressureless filling"; also refer to "Pressure Selection Valve" in the section "Operation of the Machine".
