A. Full internal rinsing
In-field diluting of remaining spray liquid residues in the spraying circuit for spraying the liquid in the field, before cleaning
the sprayer.
÷
Note: This rinsing is adequate/sufficient when the sprayer is going to be used again shortly (e.g. next day) in same or
similar crops (no risk of cross contamination and subsequent crop damages).
±
WARNING! If the next crop to be sprayed is sensitive to the latest chemical used, then a full cleaning should be carried
out. See “D: Full internal cleaning (Soak wash)” on page 60.
±
WARNING! Never clean the sprayer if there are risks of contamination of surface or underground water! Choose a
different spot for cleaning every time to avoid spot contamination to build up.
€
DANGER! Before commencing this rinsing procedure, ensure that the Pressure Empty quick coupler cap is securely
fitted and tightened! If this is not fitted and tightened properly, it may burst off during the rinsing process and lead
to personal injuries to the operator or persons in proximity of the machine!.
This rinsing procedure will rinse the spraying circuit and main tank as follows:
1. Open the spray boom (if it isn’t already opened) and lower the boom.
2. Empty the sprayer as much as possible. Close the agitation valve (no agitation). Allow the pump to run until all nozzles
stop spraying to ensure that all relevant liquid has been expelled.
3. Turn on the Rinse Tank Valve (This will automatically turn off the Main Tank Valve).
4. Turn on the Agitation valve.
5. Engage the pump.
6. Use 1/6 of the rinse tank contents at this valve setting.
7. Turn the ChemFiller/Ejector valve to off.
8. Turn off the Agitation Valve for 10 seconds.
9. Turn on the Tank Rinse nozzles for 20 seconds.
10. Turn the Chemfiller/Ejector valve to boom “Spraying”.
÷
Note: If you want to spray out the diluted liquid while driving in the field, return to the cabin. The rest of the cleaning
process can be controlled from there.
÷
Note: If you want to spray out the liquid beside the field with the sprayer parked, the rest off the cleaning process can
be controlled from the side of the machine.
11. Open the Boom Spray nozzles with the ON/OFF switch.
12. Open the CycloneFilter valve located at the bottom of the filter fully by pressing it upwards for 10 seconds. This will
flush out the sedimentations in the bottom of the filter.
13. Press the Main Tank valve to turn it on. This will automatically close the Rinse Tank valve.
14. If powder has been used, turn on the agitation from the control panel. If the agitation is too strong, you can decrease
it gradually from the cabin. Spray out the contents fully. If spraying in the field, choose a different location each time
to distribute the spray liquid residues over larger areas. Continue until all fluid is expelled from the boom tubes and
nozzles.
15. Turn on the Rinse Tank valve, this will automatically close the Main Tank valve.
16. Turn on the Tank Rinse nozzles and turn off the Boom Spray nozzles and run it for 1 minute.
17. Turn off the Tank Rinse nozzles. Turn on the Main Tank valve. Turn on the Boom Spray nozzles and spray until the Main
Tank is empty.
18. Repeat step 15-17 another 3 times using 1/6 off the rinse tank contents in each of the 3 sequences until the Rinse Tank
is empty.
19. Shut off nozzles once the rinsing process is completed.
