12.7 Residual quantities
A differentiation is made between two types of residual quantities:
•
Residual quantity remaining in the wash container after the end of spraying operation.
•
Technical residual quantity which still remains in wash container, suction fitting and spraying line, with
considerable drop in pressure. The suction fitting consists of the ball valve and pump modules. For
technical residual quantities in the individual components refer to chapter 1.7 "Technical data". Add the
technical residual quantities of the individual components.
12.7.1 Disposal of residual quantities
Please bear in mind, that the residual quantities in the spraying line will still be sprayed out in undilut-
ed concentration. Strictly spray this residual amount on an untreated area. Refer to chapter 11.9.3 for
the required travel distance for spraying the undiluted residual quantity. The residual amount in the
spraying line depends on the working width of the boom.
Switch on the agitator to spray the wash container empty , if the residual quantity in the wash contain-
er is only 100 litres. With the agitator switched on the technical residual quantity increases in contrast
to the specified values.
Measures to protect the user must be applied when emptying residual quantities.
Follow the instructions of crop protection product manufacturers and wear appropriate protective
clothing.
Dispose of collected wash residues in compliance with applicable, statutory regulations. Collect wash
residues in suitable containers.
Allow the wash residues to dry up. Dispose of wash residues through the specified waste disposal.
12.7.2 Diluting residual quantities in the wash container and spraying
of the diluted residual quantity at the end of the spraying operation
Perform the dilution and spraying of residual quantities at the end of spraying operation using the sedimentation
method.
Proceed as follows:
1. Dilute the residual quantity in the wash container with 200 litres of flushing water.
2. First spray the undiluted residual quantity out of the spraying line
on an untreated remnant area.
3. Then spray the diluted residual quantity also on an untreated remnant area.
4. Dilute the residual quantity in the wash container once again with 200 litres of flushing water.
5. Then spray the diluted residual quantity again on an untreated remnant area.
