Cleanin g the Tank and Liquid System
μ
ATTENTION! Thorough cleaning of the sprayer is to be carried out whe n shifting to crops, which are ver y sensitive to
chemicals just sprayed, or prior to storage for a longe r period of time.
÷
NOTE! Pr ior to the descr ibed cleaning, a standard cleaning should be carried out.
• Select and use the appropriate protective clothing. Select detergent suitable for cleaning and suitable deactivating
age nts if ne cessary.
• Rinse and clean sprayer and tractor externally. Use detergent if necessar y.
1. Remove tank filter s and suction filters and cle an the sprayer. Be care ful not to damage the filter mesh. Put back the
suction filter top. Put back all filters, when the sprayer is completely cle an.
2. With the pump running, rinse the inside of the tank. Do not forget to cle an the tank roof. Rinse and operate all
components and any equipment, which have been in contact with the chemical. Before opening the distribution
valves and spraying the liquid out, de cide whether this should be done in the field or on the seepage location.
3. 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. Special detergents for
sprayer cleaning is recommended as some also lubricate ball valves e tc.
4. Start the pump and operate all controls enabling the liquid to come into contact with all the components. Operate
the distribution valves as the last thing. Some detergents and de activating agents work best, if they are le ft in the tank
for a short pe riod. Check the label.
5. Drain the tank and let the pump run dr y. Rinse inside of the tank, again letting the pump run dry.
6. Stop the pump. If the pesticides used have a tendency to block nozzles and filters, remove and clean them
immediately.
7. Put back all the filters and nozzles and store the sprayer. If it is noted, from previous expe riences, that the solvents in
the pesticides are particularly aggressive, store the spr ayer with the tank lid open.
μ
ATTENTION! It is advisable to increase the forward speed (double, if possible) and reduce the spr aying pressure to 1 . 5
bar, when spraying diluted remaining liquid in the field just sprayed.
μ
ATTENTION! If a cleaning procedure is given on the chemical label, follow it closely.
μ
ATTENTION! If the sprayer is cle aned with a high pressure washer, lubrication of the entire machine is recommended.
C leanin g and Main ten an ce of Filters
Cle an filters ensure:
• Sprayer components such as valves, diaphragms and operating units are not hindered or damaged during operation.
• Nozzle clogging 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 Cleaning Agent
It is recommended to use an appropriate cleaning age nt suitable for cleaning agricultural sprayers.
• Cleaning agents containing a suitable lube or conditioner are recomme nded.
• If for some reasons this is not available, triple ammonia water is used. It is impor tant to rinse the spray circuit
immediately after, and add some lubricant to the r insing water to prevent ball valves etc. seizing up.
• Use of automotive antifreeze/radiator coolant (ethylene glycol) will protect valves and seals from drying or seizing up.
