Cleaning
1.Dilute remaining spray liquid in the tank with at least 10 parts water and
spray the liquid out in the field you have just sprayed.
NOTE: It is advisable to increase the forward speed (double if possible)
and reduce the pressure. For S4110 nozzles, pressure may be reduced
to 1.5 bar.
2.Select and use the appropriate protective clothing. Select detergent
suitable for cleaning and suitable deactivating agents if necessary.
3.Rinse and clean sprayer and tractor externally. Use detergent if neces-
sary.
4.Remove tank and clean. Be careful not to damage the mesh. Replace
when the sprayer is completely clean.
5.With the pump running, rinse the inside of the tank. Remember the tank
roof. Rinse and operate all components and any equipment that has
been in contact with the chemical.
Before opening the distribution valves and spraying the liquid out,
decide whether this should be done in the field again or on the
soakaway.
6.After spraying the liquid out, stop the pump and fill at least 1/5 of the
tank with clean water. Note that some chemicals require the tank to be
completely filled. Add appropriate detergent and/or deactivating agent,
e.g. Washing soda or Triple ammonia.
NOTE: If a cleaning procedure is given on the chemical label, follow it
closely.
7.Start the pump and operate all controls enabling the liquid to come in
contact with all the components. Leave the distribution valves until last.
Some detergents and deactivating agents work best if left in the tank
for a short period. Check the label.
8.Drain the tank and let pump run dry. Rinse inside of tank, again letting
the pump run dry.
9. Stop the pump. If the pesticides used have a tendency to block nozzles
and filters, remove and clean them now.
10. Replace all the filters and nozzles and store the sprayer. If, from
previous experiences, it is noted that the solvents in the pesticide are
particularly aggressive, store the sprayer with the tank lid open.
NOTE: If the sprayer is cleaned with a high pressure cleaner we
recommend lubrication of the entire machine.
