Quick reference - Cleaning
In the following diagram, valve positions for different options are described.
Technical residue
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 residues in the tank should be diluted immediately in the relationship 1:10 with clean water and sprayed onto the crop
just sprayed before cleaning the sprayer.
Using the drain valve
The drain valve is located and operated from the left hand side of the
sprayer near the boom transport bracket. 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.
