7 MAINTENANCE
The UC4+ Sprayer Boom Height Control System requires very little
maintenance. However, some minor procedures will help ensure that your
system operates properly for many years.
Before each day of operation:
9
Peak performance requires low friction on the boom roll mechanism.
Used to hold the boom stable, friction pads are often prone to high
amounts of friction when dry. Grease as necessary. This is especially
important on systems equipped with Active Roll control.
9
Ensure breakaway brackets are well lubricated and function properly.
9
Clear any obstructions between the sensor and the ground. Any object
within a 15 cm (6 inch) diameter circle directly below the sensor could
cause improper height readings. Check to ensure hydraulic hoses, sensor
cables, or debris is clear of the sensor.
9
Inspect the foam insert in each sensor. Fitted into the bottom of the
sensor is a foam shield that can become clogged with dust and dirt.
Remove the foam from the sensor, blow it out with an air compressor if
available, and reinsert. Replace the foam inserts as necessary.

Figure 9 – Protective Foam Shield
At the End of a season:
9
Remove the sensors and store inside.
9
Replace oil filter in the NORAC hydraulic manifold (PT#: 104827)
annually.
9
Replace ultrasonic transducer as needed. Over time, performance of the
inexpensive transducer element may become degraded from airborne
contamination (typical life is 3-10 years). Contact NORAC for
information.
Do not blow out the foam shield while it is still installed in the sensor.
Sensor damage may result. Always remove the foam shield for cleaning.
