MAIN COMPONENTS OF SPRAYER
ATTENTION
In order to ensure longer life of the pressure gauge, after calibrating the sprayer, turn off
the control, thus releasing the pressure, and close the pressure gauge valve.
MASTERFLOW SPRAY CONTROL
Besides providing great sensitiveness and precision in the adjustments, it has basic
functional characteristics in relation to conventional controls.
- LEVERS OPERATION
The levers can be operated through cables or electric switches.
- FLOW PROPORTIONAL TO ROUTING
Within a same working gear, even if the engine rotation is changed, the application rate
per area sprayed remains unchanged.
- KEEPS THE SAME PRESSURE ALONG THE WHOLE BOOM REGARDLESS OF NUM-
BER OF BOOM SECTIONS IN USE
It has a system that allows to calibrate the return of each boom section and keep constant
the pressure, regardless of the number of sections on or off.
DIFFERENT CONTROL OPTIONS
Your equipment can be equipped with one of the following spray controls.
- MASTERFLOW spray control with cable actuation
- MASTERFLOW spray control with cable actuation and JSC
- MASTERFLOW spray control with electric actuation
- MASTERFLOW spray control with electric actuation and JSC
The instructions for the control calibration are practically the same, except for turning on
and off the chemical flow to the booms, which can be made through cable or electric switch.
Identify in the figures below which is the control installed in your sprayer and proceed
as described in the section MAIN COMPONENTS OF SPRAYER - CALIBRATING THE
MASTERFLOW SPRAY CONTROL.

NOTE: The JSC (JACTO SPRAYER CONTROL) is a flow controller that keeps the spraying vo

lume (L/ha) always constant, regardless of speed fluctuations with or without
change in the working gear, besides monitoring the spray application.
