Technical Residue
An amount of spray liquid will inevitably remain in the system. It cannot be sprayed properly on the crop, as the pump takes
in air when the tank is just about empty.
This technical residue is defined as the remaining amount of liquid in the system when the first clear pressure drop appears
on the pressure gauge. See “Technical Residue” on page 152.
The residual dilutable volume is approx. 18 gal (69 l).
The residues in the tank should be diluted immediately in a ratio of 1:10 with clean water and then sprayed on the crop just
sprayed with increased driving speed. However, it must be noted that the liquid in the spray lines (with unchanged
concentration) will be sprayed out first. Therefore there should be an untreated field area available to spray this liquid out.
In addition, the rinsing tank is used to separately rinse pump.
Follow all regulations when disposing of chemical residues.
Using the Drain Valve
The drain valve is operated from the platform just beside the main tank
lid.
1. Pull the string to open the drain valve.
2. The valve is spring-loaded, but can be kept open by pulling the
string upwards in the V-shaped slit.
3. To release, pull the string downward and the valve will close
automatically.
