will vary depending on the parameters set by the user and the OEM. Buttons on the Work screen give access to all the functions which
are required during operation, and will change with the Operation Mode selected.

Droplet Size Chart
When choosing a spray nozzle that produces droplet sizes in
one of the eight droplet size classification categories, always
remember that a single nozzle can produce different droplet size
classifications at different pressures. A nozzle might produce
medium droplets at low pressures, while producing fine droplets as
pressure is increased.

NOTE: Droplet size classifications are based on BCPC
specifications and in accordance with ASABE Standard
S572.1 at the date of printing. Classifications are subject
to change.
