Use of detergents
It is recommended to use an appropriate cleaning detergent suitable for cleaning agricultural sprayers.
• The cleaning detergents which contain a suitable lube or conditioner is recommended.
• If for some reason this is not available and e.g. triple ammonia water is used, it is important to rinse the circuit
immediately after and add some lubricant to the rinsing water to avoid e.g. ball valves seizing up.
• Use of automotive antifreeze/radiator coolant (ethylene glycol) will protect the valves, seals etc. from drying or seizing
up.
Technical residue
Inevitably a quantity of spray liquid will remain in the system. It cannot be sprayed properly on the crop, as the pump takes
in air when the tank is about to be empty.
This Technical Residue is defined as the remaining liquid quantity in the system as the first clear pressure drop on the
pressure gauge is read.
The dilutable residue must be diluted 10 times with clean water and sprayed to the crop just sprayed before cleaning the
sprayer.
Cleaning and maintenance of filters
Clean filters ensure:
• Sprayer components such as valves, pumps and operating unit are not hindered or damaged during operation.
• Nozzle blockages do not occur while spraying.
