OPERATING INFORMATION
Main Solution Switch
Main spray power can be controlled from two different loca-
tions: a floor-mounted “dimmer-style” switch (fig. 4.38) or a
switch mounted on the hydrostatic control lever (fig. 4.39). Ei-
ther one controls the power supply to the panel of boom
solution valve switches (fig. 4.43). One of the switches must be
on to supply the switches with voltage. This way you can turn
all of the boom solution valves “ON” or “OFF” all at once in a
hands-free execution such as turning the main solution switch
“OFF” as you arrive at the end rows of a field and turn it back
“ON” as you enter the field again. Whichever switch supplied
the power to the boom solution valve switches must be the one
you turn off to disconnect the power; i.e. if you use the switch
on the hydrostatic control handle to turn the power on, you will
not be able to turn the power off with the floor switch, you must
use the switch on the handle.
When the main spray power is “ON” a “GREEN” indicator
light mounted at the bottom of the message center will light up
(fig. 4.40). When the light is not lit, the main solution switch is
“OFF.”
