5 - Operation
Use of rinsing tank and rinsing nozzles (optional)
The incorporated rinsing tank can be used for two different purposes.
ATTENTION! If a cleaning procedure is given on the chemical label, follow it closely.
In-field diluting before cleaning
In-field diluting of remaining spray liquid residue in the spraying circuit, before cleaning the sprayer.
Rinsing the tank and liquid system
1. Empty the sprayer as much as possible. Close the AgitationValve (no agitation) and spray till air comes out of all
nozzles.
2. Turn suction valve towards “Rinsing tank” and pressure valve towards “Spraying”.
3. Engage and set the pump at approximately 300 r.p.m.
4. When 1/3 of the contents in the rinsing tank is used, turn suction valve towards “Main tank” and operate all valves
on the pressure side of the system in the following order so that all hoses and components are rinsed:
I. Turn the pressure valve towards TurboFiller (if fitted) and open the TurboFiller suction valve.
II. Open TurboDeflector valve and close it again when clean water comes out of nozzles.
III. Close TurboFiller lid and squeeze the Chemical Container Cleaning grip to clean this device.
IV. Open TurboFiller lid again and make sure that TurboFiller is empty.
V. When empty, close the TurboFiller suction valve again.
VI. Turn the suction valve towards “Main tank” and the pressure valve towards “Spraying” and spray the liquid in
the field just sprayed.
Cleaning of Main tank
5. Turn the suction valve towards “Rinsing tank” and the pressure valve towards “Internal Tank Rinsing”. Remove the
filling strainer to avoid any cleaning shadows behind it.
6. When another 1/6 of the contents in the rinsing tank is used, turn the suction valve towards “suction from Main
tank”.
7. Turn pressure valve towards “Spraying” and spray the liquid in the crop/orchard just sprayed.
8. Repeat point 6 - 8 one more time.
WARNING! When critical chemicals have been used, before spraying another crop/orchard sensitive to the
chemical just used or a cleaning detergent is recommended, do an extra cleaning:
9. Fill the rinse tank again.
10. Fill the main tank with 500 l clean water.
11. Add the cleaning detergent to the main tank by using the TurboFiller. Follow instructions on the label of the
cleaning agent.
12. Clean the whole system again.
13. To get the best cleaning effect the Self-Cleaning Filter and the Suction Filter sieves should be washed with clean
water.
14. Rinse the sprayer with clean water afterwards.
ATTENTION! The rinsing nozzles cannot always guarantee a 100% cleaning of the tank. Always clean manually
with a brush afterwards, especially if crops sensitive to the chemical just sprayed are to be sprayed afterwards!
