C. Rinsing spraying circuit without diluting main tank content
This procedure is used to rinse the pump, operating unit, spray lines, etc. in case of stop in spraying before main tank is empty
(e.g. beginning rain etc.).
Rinsing of the liquid system
1. Turn the suction SmartValve to “Rinsing tank”. (Keep pressure SmartValve in “Spraying” position).
÷
NOTE! The main ON/OFF on the Grip must be ON. Closing the main ON/OFF will transfer the rinse water back to the
main tank!
2. Close agitation valve (no agitation).
3. Turn off the Cyclone Filter Boost Valve to avoid dilution of main tank content.
4. Engage the pump and spray water from rinsing tank in the field until all nozzle tubes/nozzles are flushed with clean
water.
5. Disengage the pump again.
ATTENTION! It is advisable to increase the forward speed (double if possible) and reduce the pressure to 20 psi (1.5
bar) when spraying diluted remaining liquid in the field just sprayed.
ATTENTION! If a cleaning procedure is given on the chemical label, follow it closely.
ATTENTION! If the sprayer is cleaned with a high pressure cleaner lubrication of the entire machine is recommended.
D: Full internal cleaning (Soak wash)
÷
NOTE! This cleaning procedure is always used when:
• The next crop to be sprayed is at risk to be damaged by the chemical just used, or
• The sprayer is not going to be used again for same chemical or crop right away, or
• 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 instructions 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 “A. Full internal rinsing” on page 58).
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 120 gal [450 liters], 160 gal [550 liters] and 200 gal [700 liters]). Fill the rinsing tank completely. This water
is used later for rinsing.
4. Shut off all nozzles with the main ON/OFF button on the grip.
5. Turn suction SmartValve to “Main tank” and pressure SmartValve to “Spraying”. Set agitation valve to “Full agitation”.
6. Engage and set the pump at approximately 300 r.p.m. Engage auxiliary pump (FlexCapacity configurations only).
7. Allow the liquid in the main tank to circulate for at least 3 minutes with the nozzles shut to clean the return lines from
boom to tank.
8. Close the agitation valve and turn the pressure SmartValve to “TurboFiller” for at least 10 seconds without activating
the TurboFiller in order to burst and flush the safety valve.
9. Open the TurboFiller transfer valve and the deflector valve and allow liquid to circulate for 3 minutes.
10. Close the lid and activate the container rinsing valve to clean the hopper inside.
11. Shut off all three valves on the TurboFiller again.
