Retune

From time to time it may be necessary to recalibrate (Retune) the UC4.5 electronics to the
sprayer’s hydraulics. Examples of such times are:



A hydraulic solenoid valve has been changed.



The hydraulic pump has been changed or adjusted.



A different tractor has been connected to the sprayer.



The tractor’s hydraulic flow control has been adjusted.

If running a pull type sprayer and using different tractors to operate the sprayer, run the Retune
procedure each time the tractor is changed. If there is a flow control for the boom hydraulics,
set it prior to tuning. If the flow setting is changed by more than 20 percent, run a Retune.

Follow

Section 8.1.1

(level booms, working RPM, etc.) before beginning the Retune. Navigate

to the "Retune?" menu prompt in the SETUP (

) menu and confirm with the

button. The

procedure described in the Automatic System Setup, starting at

Section 8.1.7

will begin.

Note: The booms are to be leveled at a normal working height when Retune starts – it is not necessary
to set them to 35 inches. The 35 inch height is only required during the Automatic System Setup.
