GENERAL INSTRUCTIONS FOR SPRAYING
For a successful spraying, the appropriate water quantity, right nozzle selection and a precise
consumption calculation are of major importance. It is recommended to stick to the following order
when it comes to preparing of the spraying mixture and spraying:
Make sure that the spraying appliance is in flawless condition. Check the oil level of the pump
and clean all filters.
Read the instructions which are attached to the protective agent. Pay special attention to the
prescribed concentration, the dose for a hectare and the recommended water consumption.
Choose an appropriate tractor speed and – if you do not have a reliable value – measure it. It is
very important to have precise speed values when it comes calculating the quantity of the
mixture.
Choose appropriate nozzle type and size according to the crop and required water
consumption. Use the nozzle tables.
Fill the reservoir with half of the fresh water you will need.
Adjust the working pressure on the regulator and check the liquid flow rate through the
nozzles.
Calculate the required water consumption per hectare according to the measured liquid flow
rate through the nozzles and the working speed.
Fill the reservoir with the mixture and add the required water quantity.
While working, pay attention to a constant working speed, the height of the spraying
equipment, the working pressure and nozzle operation.
Clean the sprayer after you finish working.
17.1
Connection for checking the pump flow rate measurement
The flow meter for the pump can be connected to the return line of the pressure regulator. To do this,
remove the hose fitting and replace it with another fitting to connect the flow meter with the reservoir.
During this procedure, all other regulator supply lines must be closed so that the entire amount of liquid
is pumped into the reservoir through the return line.
17.2
Nozzle flow rate measurement check
To measure the nozzle flow rate, you will need a piece of flexible plastic or rubber tube with an internal
diameter of 25 mm or 1˝ and a suitable collection container (a measuring glass is recommended).
Simply insert the tube on the nozzle and measure the flow volume on each nozzle by catching the
liquid with the collection container. You will also need a timer or a watch to measure the flow volume.
The measurement should last one minute. If the measurement is shorter than that, the measured flow
volume should be calculated to one minute. If the measured flow volume at the specified pressure
exceeds the value from the table by more than 10 %, the nozzle insert is worn out and must be replaced.
WARNING: The machine IS NOT SUITABLE FOR LIQUID FERTILIZERS! If
you intend to make an exception, we recommend that you consult the technical
service department.
