Cleaning And Maintenance Of Filters; Use Of Rinsing Tank And Rinsing Nozzles; Full Internal Rinsing - Hardi COMMANDER TWIN FORCE Instruction Book

Cleaning and maintenance of filters

Clean filters ensure:
• Sprayer components such as valves, diaphragms and operating unit are not hindered or damaged during operation.
• Nozzle blockades do not occur whilst spraying.
• Long life of the pump. A blocked suction filter will result in pump cavitation. The main filter protecting sprayer
components is the suction filter. Check it regularly.

Use of rinsing tank and rinsing nozzles

The incorporated rinsing tank can be used for three different purposes:
A. Full internal rinsing or cleaning.
B. External cleaning (can only be carried out on completion of "A").
C. Rinsing spray circuit without diluting main tank content.
ATTENTION! The cleaning procedures stated requires the TurboFiller to be cleaned on beforehand (directly after the
last chemical filling). If the TurboFiller for some reason is not cleaned please carry out this cleaning before attempting
the cleaning procedures A, B or C - see "TurboFiller rinsing" on page 68.
Note that this cleaning will then use water from the rinsing tank reducing the available quantity for cleaning
procedures A, B or C.
ATTENTION! Do NOT fill any cleaning detergents into the rinsing tank. If cleaning agents are to be used this should
be added the main tank.
A. Full internal rinsing
In-field diluting of remaining spray liquid residues in the spraying circuit for spraying the liquid in the field, before cleaning
the sprayer.
÷
NOTE! This rinsing is adequate/sufficient when the sprayer is going to be used again shortly (E.g. next day) in same or
similar crops (No risk by cross contamination and subsequent crop damages).
±
WARNING! If the next crop to be sprayed is sensitive to the latest chemical used a full cleaning should be carried out.
See "Full internal cleaning (Soak wash)" on page 76.
±
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.
€
DANGER! Before commencing this rinsing procedure ensure that the blind cap is securely fitted and tightened on the
PressureEmpty quick-coupler! If this is not fitted and tightened properly it may burst off during the rinsing process
and lead to personal injuries to the operator or persons in proximity of the machine!
This rinsing procedure will rinse the spraying circuit and main tank as follows:
1. Empty the sprayer as much as possible. Close the agitation valve (no agitation). Allow the pump to run for at least 1
minute after the liquid fan from the nozzles has collapsed to ensure that all relevant liquid has been expelled.
2. Turn suction SmartValve towards "Rinsing tank" and pressure SmartValve towards "Main tank". Set agitation valve to
"Full agitation".
3. Engage and set the pump at approximately 300 rpm.
4. Use 1/6 (approximately 75 l) of the rinsing tank content at this valve setting.
5. Turn the pressure SmartValve towards "Pressure Empty/TurboFiller" for minimum 3 seconds to burst and flush the
safety valve. The TurboFiller is not flushed by this operation.
6. Turn the agitation valve towards "FastFiller flushing" and use another 1/6 (approximately 75 l) of the rinsing tank
content for flushing the FastFiller lines.
