4 INSTALLATION PROCEDURE

4.1 EXISTING SYSTEM CHECK

It is necessary to check the existing system’s

functionality before installing the UC4+ Spray

Height Control system.

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 3.

It is necessary to test the boom

functions in all directions

OOM SPEED TEST

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 4.

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 4, “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 4, 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 4.

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 4.

8. These “Average Times” now represent how

quickly your system can react to manual

control. In Section 4.8, this procedure is

repeated with the UC4+ Spray Height

Control system installed for comparison and

troubleshooting purposes.
