Agitation Before Resuming a Spray Job
If a spray job has been interrupted for a while, severe sedimentation may occur depending on the chemicals being used.
Before resuming the spray job, it might be necessary to agitate sediment material.
1.
Turn ‘”On” agitation valve.
2.
Engage the pump and set PTO speed to 540 rpm or 1000 rpm (depending on pump model).
3.
Agitation has started and should be continued for at least 10 minutes.
4.
The spray job can now be resumed. Turn pressure SmartValve towards “Spraying” and start spraying.
Before Returning to Refill the Sprayer
If the sprayer is to be refilled at the farm, or at a fixed filling place without a filling space with hard surface and drain to a
closed reservoir, the sprayer should be rinsed before returning to refill.
Dilute the residues of the spraying circuit, and spray it on the crop. Now rinse the sprayer on the outside with the External
Cleaning Device (optional equipment), before returning to the farm.
±
WARNING! Always follow local legislation in force at any time.
Parking the Sprayer
To avoid spot contamination, the sprayer should always be parked at either the washing/filling location or under roof.
This prevents rainfall from washing down chemical residues from the sprayer's surfaces.
•
Parking at the washing/filling location will retain residues.
•
Always park the machine out of reach of children, animals and unauthorized persons.
Liquid Fertilizer
Spraying pressure
If you are spraying with liquid fertilizer instead of pesticides, the spraying pressure must be increased in comparison to
pesticide spraying to get the desired output (l/ha).
The density for liquid fertilizer is normally higher than for water and spray liquids - so to get the correct output (l/ha), the
spraying pressure must be adjusted.
Example:
Nozzle output is 2.40 l/min at 3.0 bar pressure. Density of liquid fertilizer is 1.20 g/cm³.
Multiply the pressure value with the density value: 3.0 x 1.2 = 3.6; the adjusted pressure is then 3.6 bar for spraying the liquid
fertilizer.
