Inevitably a quantity of spray liquid will remain in the system. It cannot be sprayed properly on the crop, as the pump
takes in air when the tank is about to be empty.
This Technical Residue is defined as the remaining liquid quantity in the system as the first clear pressure drop on the
pressure gauge is read.
The residue of the individual sprayers are to be taken from the table.

The values are measured with sprayer in level and apply to the complete equipment. During slope inclinations to 20 %
these values remain constant. The residues in the tank should be diluted immediately in the relationship 1:10 with water
and afterwards be sprayed to the crop just sprayed with increased driving speed. In addition the rinsing tank is to be
used, with this can also pump, linkage and armature separately be rinsed. It is to be made certain however that the liquid
in the lines in unchanged concentration is sprayed out, so there should be an untreated patch available.
The drain valve is located and operated from the platform just besi-
de the main tank lid. Pull the string to open the drain valve. The
valve is spring-loaded, but can be kept open by pulling the string
upwards in the V-shaped slit. To release, pull the string downward
and the valve will close automatically.
If draining residues, e.g. liquid fertilizer into a reservoir, a snap-coup-
ler with hose can rapidly be connected to the drain valve and the
liquid safely drained.
