XISTING SYSTEM CHECK
It is necessary to check the existing system’s
functionality before installing the UC4+ Spray
Height Control.
1.
Drive your sprayer onto a flat piece of land,
with unobstructed boom movement (e.g. no
power lines).
2.
Test that all boom functions operate
correctly. As you test each function check it
off in
Table 5
.
It is necessary to test the boom
functions in all directions

IMPORTANT:
Raise/lower all boom sections several
times to warm up the hydraulic system.
Grease all moving parts for consistent
results.
1.
Lower each boom and main section as close
to the ground as possible.
2.
Set your sprayer at field working RPM on
the throttle and mark this value in
Table 6
.
You will need a stopwatch or a
watch that displays “seconds” for
the next step.
3.
Raise the LEFT boom from its extreme
LOW position to the very TOP of its travel.
Record the time this takes in
Table 6
,
“Trial
#1” for “Left UP”.
4.
Lower the LEFT boom from its extreme
HIGH position to the BOTTOM of its travel.
Record this time in
Table 6
, Trial #1 for
“Left DOWN”.
Be careful when lowering the
booms so they don’t hit the ground.
5.
Similarly, record two more time trials (Trial
#2 & #3) for the LEFT boom and record in
Table 6.
6.
Repeat Steps
1
through
5
for the RIGHT,
MAIN and ROLL functions.
Your sprayer may not have a roll
feature.
7.
Average the three trials recorded for each
boom movement and record this calculation
in the “Average Time” slot in
Table 6.
8.
These “Average Times” now represent how
quickly your system can react to manual
control. In
Section 4.9
, this procedure is
repeated with the UC4+ Spray Height
Control installed for comparison and
troubleshooting purposes.
