External Cleaning - Hardi COMMANDER TWIN FORCE Instruction Book

7. Shut off all nozzles by the main ON/OFF button on the grip.
8. Turn suction SmartValve towards "Main tank" and the pressure SmartValve towards "Spraying". Engage the auxiliary
pump (FlexCapacity configurations only). Set the spraying pressure at 3-5 bar. If the pressure is set outside this range
the rinsing result may be insufficient.
9. Allow the rinsing water in the main tank to circulate for minimum 45 seconds with the nozzles shut to flush the return
lines from boom to tank.
10. Open all nozzles and spray the rinsing water from the main tank through the nozzles while driving in the field. Choose
a different location each time to distribute the rinsing water over larger areas. Continue until all fluid is expelled from
the boom tubes and nozzle - this may take several minutes after the spray fan has collapsed.
11. Shut off all nozzles by the main ON/OFF switch.
12. Turn the suction SmartValve towards "Rinsing tank" and the pressure SmartValve on "Tank rinsing". Use another 1/6
(approximately 75 l) for this. The tank strainer should be removed to avoid shading for the rinsing nozzle.
13. Turn the suction SmartValve towards "Main tank" and the pressure SmartValve towards "Spraying". With the nozzles
shut allow the liquid to circulate for minimum 30 seconds to flush the return lines from boom to tank.
14. Open all nozzles by the main ON/OFF switch and spray the rinsing water from the main tank through the nozzles until
all liquid is expelled from the boom tubes/nozzles.
15. Repeat step 11-14 another 3 times using 1/6 (approximately 75 l) of the rinsing tank content in each of the 3 sequences
until the rinsing tank is empty.
16. Shut off the nozzles at the main ON/OFF button once the rinsing process is complete.
B. External cleaning
This procedure is used to rinse the sprayer on the outside in the field as required with the External Cleaning Device.
÷
NOTE! Before attempting an external rinsing, make sure the main tank is rinsed (see "A. Full internal rinsing" on
page 74) and empty! Any liquid left in the main tank will be mixed with the clean water for external rinsing!
÷
NOTE! Approximately 100 l of clean water in the rinsing tank will allow approximately 15 minutes of rinsing (Cleaning
nozzle consumption is 6 l/min at 10 bar pressure).
±
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.
1. Engage pump at approximately 300 r.p.m. or 560 r.p.m. depending
on pump model.
2. Turn suction SmartValve towards "Rinsing tank" and pressure
SmartValve towards "Internal Tank Rinsing".

DANGER! Before turning Pressure SmartValve to "Pressure
draining/TurboFiller" it is very important to be sure that the quick
coupler lid is correct and completely mounted to the filling stud
into its locked position. Failure to do so may cause risk of
contamination and injury from quick coupler lid being "shot" off
when pressurized! If not possible to mount lid completely,
lubricate the rubber seal and the grip hooks.
