Rinsing when main tank is not empty
Rinsing the pump, operating units, spray lines, etc. in case of stop in spraying (e.g. because of rain), before main tank is empty.
Cleaning of the liquid system:
1.
Turn suction valve towards . (Keep pressure SmartValve in -position).
2.
Close AgitationValve (no agitation).
3.
Engage the pump and spray the water from the rinsing tank into the field, until all nozzle tubes and nozzles have been
flushed with clean water.
4.
Disengage pump again.
μ
ATTENTION! It is advisable to increase the forward speed (double, if possible) and reduce the spraying pressure to 1.5
bar, when spraying diluted remaining liquid in the field just sprayed.
Cleaning the sprayer on the outside
1.
Turn suction valve towards and pressure SmartValve towards .
2.
When another 1/3 of the contents in the rinsing tank is used, turn the suction valve towards .
3.
Turn pressure Agitation valve towards and wash the sprayer with the cleaning device located on sprayer’s right
side.
4.
Disengage pump again.
μ
ATTENTION! If the sprayer is cleaned with a high pressure washer, lubrication of the entire machine is recommended.
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. The residual dilutable volume is 41 litres. See “Technical Residue” on page 122 for specific technical
residues.
The residues in the tank should be diluted immediately in a ratio of 1:10 with clean water. Afterwards it should be sprayed
on the crop just sprayed with increased driving speed. In addition, also pump, linkage and armature can be separately rinsed
with water from the rinsing tank. However, it must be ensured that the liquid in the spray lines are in unchanged
concentration. Therefore there should be an untreated field area available to spray this liquid out.
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.
If draining residues, e.g. liquid fertilizer into a reservoir, a snap coupler
with hose can rapidly be connected to the drain valve, and the liquid is
safely drained.
