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 recommend-
ed.
1. Dilute remaining spray liquid in the tank with at least 10 parts of water and spray the liquid out in the field you have
just sprayed.
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 necessary.
4. Remove tank and suction filters and clean. Be careful not to damage the mesh. Replace suction filter top. Replace filters
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 liq-
uid 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.
7. Start the pump and operate all controls enabling the liquid to come in contact with all the components. Leave the dis-
tribution valves until last. Some detergents and deactivating agents work best if left in the tank for a short period. Check
the label. The Cyclone filter can be flushed by engaging the lever in the bottom to flush position. Stop the pump and
remove the hose. Start the pump for a few seconds to flush filter. Be careful not to lose the restrictor nozzle.
8. Drain the tank and let the pump run dry. Rinse inside of the tank, again letting the pump run dry.
Clean filters ensure:
• Sprayer components such as valves, diaphragms and operating unit are not hindered or damaged during operation.
• Nozzle blockages do not occur while 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.
Cleaning and maintenance of filters
Cleaning the tank and liquid system
ATTENTION! If the sprayer is equipped with a centrifugal pump, do not run pump dry for longer than 3 seconds.
Otherwise severe damage to the pump will occur.
9. Stop the pump. If the pesticides used have a tendency to block nozzles and filters, remove and clean them immediate-
ly.
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.
