Rinsing When Main Tank Is Not Empty
Rinsing the pump, operating units, spray lines, etc. in case of stop in spraying (e.g. because of rain), before main tank is empty.
Cleaning of the liquid system:
1. Turn suction valve towards
2. Close agitation valve (no agitation).
3. To prevent diluting the tank content, close the rinsing hose for the cyclone filter.
4. Engage the pump. Set the pump speed to approximately 300 rpm and increase the spraying pressure to 6 bar. Spray
the water from the rinsing tank into the field, until all nozzle tubes and nozzles have been flushed with clean water.
5. Turn off the pump.
ATTENTION! It is advisable to increase the forward speed (double, if possible) and reduce the spraying pressure to 1.5
bar, when spraying diluted remaining liquid in the field just sprayed.
Cleaning the Sprayer on the Outside
ATTENTION! External cleaning using the spray gun is only possible with water from the RinseTank, which have been
directed through the main tank. To avoid using concentrated chemical mix from the main tank to clean the sprayer
on the outside, do a complete main tank cleaning before attempting to use the spray gun!
1. Turn suction valve towards
2. When another 1/3 of the contents in the rinsing tank is used, turn the suction valve towards
3. Turn cleaning valve to the right towards
4. Turn off the pump again.
ATTENTION! If the sprayer is cleaned with a high pressure washer, lubrication of the entire machine is recommended.
Use of Cleaning Agent
It is recommended to use an appropriate cleaning agent suitable for cleaning agricultural sprayers.
• Cleaning agents containing a suitable lube or conditioner are recommended.
• If for some reasons this is not available, and triple ammonia water is used instead, it is important to rinse the liquid
system immediately after, and add some lubricant to the rinsing 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.
Technical Residue
An amount of spray liquid will inevitably remain in the system. It cannot be sprayed properly on the crop, as the pump takes
in air, when the tank is just about empty.
This technical residue is defined as the remaining amount of liquid in the system, when the first clear pressure drop appears
on the pressure gauge.
The residual dilutable volume is approx. 40 litres. See the section "Technical Specifications" for more details.
The residues in the tank should be diluted immediately in a ratio of 1:10 with clean water. Afterwards it should be sprayed
on the crop just sprayed with increased driving speed.
In addition, also pump, linkage and armature can be separately rinsed with water from the rinsing tank. However, it must be
ensured that the liquid in the spray lines are in unchanged concentration. Therefore there should be an untreated field area
available to spray this liquid out.
Follow national regulations when disposing of chemical residues.
