Cleaning and maintaining the filters
Clean filters ensure:
• that the sprayer's components such as valves, diaphragms and regulators will not be prevented from operating or
become damaged.
• that the nozzles will not become blocked during treatment.
• that the pump will last for a long time. A blocked suction filter will cause cavitation in the pump. The main filter that
protects the sprayer's components is the suction filter. Check it regularly.
Using the rinsing tank and the rotating nozzle.
The built-in rinsing tank can be used for two purposes:
IMPORTANT! If a cleaning procedure is recommended by the manufacturer of the product used, follow it exactly.
Diluting in the field before cleaning
Dilution in the field of the dead volume contained in the spraying system before cleaning the sprayer.
Cleaning the tank and the spraying system
1. Empty the tank as far as possible. Close the agitation valve and treat until the pump is no longer primed.
2. Turn the suction valve to "Rinsing tank" and the p ressure valve to "Spray".
3. Run the pump at approximately 300 rpm.
4. After transferring one third of the contents of the rinsing tank, turn the suction valve to "Main tank" and operate all the
valves on the pressure side in the following order, to rinse all the pipes and components:
• Turn the pressure valve to "Add products" to activate the ejector and open the suction valve on the TurboFiller.
• Open the Turbo deflector valve and close it as soon as clean water appears in the bottom of the hopper.
• Close the TurboFiller lid and press the package cleaning control trigger.
• Open the filler lid and check that the hopper is clean and empty.
• Once it is empty, close the filler's suction valve again. Check that the the external quick fill connector and pipe are clean.
5. Turn the suction valve to "Main tank" and the pressure valve to "Spray" and spray the contents of the tank on to the
field that has just been treated.
Rinsing the main tank:
6. Turn the suction valve to "Rinsing tank" and the pressure valve to "Clean inside of tank". Remove the tank strainer so as
not to impede cleaning behind it.
7. Transfer approximately one sixth of the contents of the rinsing tank and then turn the suction valve to "Main tank".
8. Turn the pressure valve to "Spray" and spray the contents of the tank on to the field that has just been treated.
9. Repeat points 6 to 8 once more.

WARNING! If you have used aggressive products (such as sulphonylurea) or if a cleaning additive is recommended,
carry out an additional cleaning cycle:
10. Fill the rinsing tank again.
11. Put 500 litres of clean water into the main tank. To fill the tank, see paragraph "Water filling device".
12. Add the cleaning additive via the product filler. Follow the instructions on the label on the additive.
13. Clean the whole spraying system again.
14. Do not forget to clean the strainers on the self-cleaning and suction filters with clean water.
15. Finally, rinse the sprayer with clean water.
IMPORTANT! The use of rotating nozzles does not guarantee that the main tank will be cleaned perfectly. Finish
cleaning with a broom, especially if the crops that you intend to treat next are sensitive to the product you have just
used.
