Residual quantities
A differentiation is made between two
types of residual quantities:
¾
Excess residual quantity after the end of
spraying operation, e.g. resulting from errors
in the calculation of the application quantity,
in filling or spraying operation.
¾
Technical residual quantity , which still re-
mains in the spraying mixture container, the
suction fitting and in the spraying line after a
considerably drop in spraying pressure. The
suction fitting consists of the assembly groups
switch-over ball valve, short lines and pump.
Technical residual quantities
It must be remembered that the residual quan-
tity in the sections will be placed in the form of
undiluted concentration. This is the case when
switching to fresh water with the nozzles acti-
vated.
Strictly spray this residual quantity from the
spraying line on an untreated area. The residual
quantity in the spraying line depends on the
width of the boom.
Draining off technical residual
quantities
NOTE
Make sure that the residual quantity in the
spraying line will be sprayed out in the form of
undiluted concentration.
¾
Spray this residual quantity from the spraying
line on an untreated area.
¾
Refer to the section Technical residual quantities
for the travel distance required to spray the
residual quantity in the spraying line. The re-
sidual quantity in the spraying line depends on
the working width of the folding boom.
¾
Once the residual quantity in the spraying
mixture container has reached a level of just
100 litres switch off the agitator to spray the
spraying mixture container empty.
With the agitator switched on the technical
residual quantity increases in contrast to the
specified values.
For machines of the CCS Pro variant, the agi-
tator is automatically deactivated at a solution
tank content smaller than 1000 litres.
At the terminal the agitator can also be re-
started below this limit using the function Lower
agitator limit .
If the solution tank content is less than 50 li-
tres, the agitator is deactivated permanently
and cannot be reactivated.
¾
The user protection measures do apply when
emptying residual quantities; follow the in-
structions of the crop protection agent manu-
facturers and wear personal protective outfit.
¾
Dispose of the collected residual quantity
of spraying mixture in accordance with the
relevant statutory regulations.
¾
Collect the residual quantity of spraying mix-
ture in suitable containers.
¾
Dispose of the residual spraying mixture
quantities in the specified way.
Draining of technical residual
quantities on machines of the
CCS Pro variant
A port is provided under the pump space for
draining the technical residual quantities.
Port with cap
1. Take off the cap.
2. Place a suitable collection vessel under the
port for draining off the residual quantity.
