5 - Operation
Operating Limits
The following things are important when considering the performance of the sprayer.
• Maximum driving speed
• Pressure setting
• Minimum / maximum volume rate
The operating limits for your sprayer are closely related to:
9. Pump size
10. Boom width
11. Nozzle size
In the table below, the operating limits for volume rate are calculated, when driving at different speeds.

NOTE! The specified nozzle type is a standard flat fan nozzle. Other special nozzle types will show different results. Ask
your HARDI dealer if in doubt.
μ
ATTENTION! It is recommended not to drive faster than 16 km/h when spraying.
μ
ATTENTION! The pressure range for the nozzles are 1.5 - 5 bar (except for HARDI INJET nozzles, which are ranging from
3-8 bar). The spraying pressure should be within these limits.
μ
ATTENTION! In the table below, the specified combination of nozzle size and sprayer setup is not suitable, as the full
pressure range of 5 bar for the nozzle cannot be reached, when spraying the maximum volume rate (l/ha) on the crop.
This is due to the nozzle design.
