B. The sprayer is not going to be used again for same chemical or crop right away, or
C. Before any repair or maintenance job is going to be carried out on the sprayer.
÷
NOTE! Wash of sprayer between jobs with incompatible crops must be done according to prescriptions from the
chemical producer. Use e.g. AllClearExtra, as this is a commonly used cleaning agent. If your chemical prescribes
another cleaning agent and/or another cleaning procedure, you must follow that.
Procedure for wash with a cleaning agent, e.g. AllClearExtra:
1. Rinse the sprayer in the field (See chapter "Use of rinsing tank and rinsing nozzles" subchapter A).
2. Drive to farm fill station.
3. Prepare sprayer for cleaning with cleaning agent, e.g. AllClearExtra. Fill water in the main tank to 10% of capacity
(respectively 330 litres, 450 litres, 550 litres and 700 litres). Fill the rinsing tank completely. This water is used later for
rinsing.
4. Turn suction SmartValve towards "Main tank" and pressure SmartValve towards "Main tank". Set agitation valve to "Full
agitation".
5. Engage and set the pump at approximately 300 r.p.m. Engage auxiliary pump (FlexCapacity configurations only).
6. Allow the liquid to circulate for 3 minutes.
7. Turn the pressure SmartValve towards "Pressure Empty/TurboFiller" for minimum 10 seconds without activating the
TurboFiller in order to burst and flush the safety valve.
8. Open the TurboFiller transfer valve and the deflector valve and allow liquid to circulate for 3 minutes.
9. Close the lid and activate the container rinsing valve to clean the hopper inside.
10. Shut off all three valves on the TurboFiller again.
11. Turn the agitation valve towards "FastFiller flushing" for 3 minutes to clean the FastFiller lines.
12. Verify that all nozzles are shut at the main ON/OFF button on the grip.
13. Turn the pressure SmartValve towards "Spraying".
14. Allow the liquid in the main tank to circulate for minimum 3 minutes with the nozzles shut to clean the return lines
from boom to tank.
15. Turn the pressure SmartValve towards "Tank cleaning nozzles" and circulate liquid for further 3 minutes.
16. Spray out water with cleaning agent and chemical residue. Set the spray pressure at 3-5 bar. Note that the washing
water still contains active chemical and choose an appropriate area to spray out this. Alternatively the washings can
be dumped at the Filling/washing location and retained in an appropriate receptacle (E.g. slurry tank or similar) - see
section "Filling/washing location requirements". Spot contamination and accumulation must be avoided. Continue to
spray until all liquid is expelled from the boom tubes and nozzles.
17. Shut off all nozzles by the main ON/OFF switch.
18. Rinse the sprayer again with clean water to rinse out all remains of the cleaning agent. See section "Use of rinsing tank
and rinsing nozzles" subchapter A. "Full internal rinsing" This to avoid that the cleaning agent remains in the fluid
system. Remains could damage the next spray chemical filled into the main tank.
19. Include rinsing of the TurboFiller in step 17. Operate all 3 valves during this process.
20. Dismantle all filters (suction, pressure, in-line and nozzle filters) and clean the filter screens using clean water and
detergent.
ATTENTION! The rinsing nozzles cannot always guarantee a 100% cleaning of the tank. Clean manually with a high
pressure cleaner afterwards, especially if crops sensitive to the chemical just sprayed are going to be sprayed
afterwards!
÷
NOTE! It is the responsibility of the sprayer operator or owner that the sprayer is cleaned sufficiently to avoid
contamination of the environment, crop damages and health & safety hazards to operator and the public. HARDI
cannot be held responsible for any damages or incidents related to insufficient cleaning.
