8. Adjust the targets and sensor bracket
using a 4-foot level or a plumb line. The
goal of this step is to have the sensor
bracket and both targets in the proper
locations. The proper location of the
targets are as follows:
i) Spring target on the centerline of
the sensor.
ii) Frame target ½" to the left side of
the centerline .
Ensure the sprayer is level AND
the booms are level when
installing the roll targets.
9. Hang a plumb line down the center of
the sensor mounting hole of the sensor
bracket. Check each target and
compare them to the proper location.
See Figure 17.
i) Ensure that both the roll and spring
targets are perpendicular to the
sensor.
ii) If both targets are to one side of the
plumb line, adjust the location of the
spring target bracket using the
adjustable ball and socket mount.
iii) The frame target can be adjusted by
sliding the bracket along the parallel
lift frame. This target should be
located ½" off the centerline.

10. When the target positions are correct
ensure all mounting bolts are tight, then
double-check the target locations to ensure
that they haven’t drifted out of position.
Some adjustment of the Sensor Roll
Bracket may be necessary to achieve
proper alignment.
11. Once alignment is correct, trim the top rod
so it is 1 inch past the edge of the sensor, as
shown above in Figure 19.
