10 Maintenance
The UC5 Height Control System requires very little maintenance, but there are a few
procedures that will ensure the system continues to work correctly for many years.
Before each day:
 It is highly recommended that the sprayer friction pads are greased. This will ensure the
boom is pivoting separately from the sprayer. It is very important to keep the friction
pads greased on active roll systems. It may be necessary to grease the friction pads
multiple times throughout each day.
 Ensure the UC5 sensor breakaway brackets are functioning correctly.
 Ensure that there is a clean, dry foam disc inserted in each sensor. The foam disc must be
pushed inside the sensor housing so that it lays flat.
 Inspect the foam disc insert in each sensor. If it is clogged with dust or other debris, clean
it. When the foam is removed from the sensor, it can be blown out with an air
compressor. If necessary, replace the foam. The UC5™ system must always be operated
with the foam disc insert in each height sensor.
At the end of the season:
 Remove the height sensors from the sprayer and store inside. Record the sensor serial
numbers in Figure 9 (Section 7.4.2) to ensure each height sensor is returned to its
original location at the start of the next season.
 If necessary, contact your NORAC dealer to have the sensors recalibrated or repaired. A
typical sensor can operate three to ten years without requiring attention.
 Replace the oil filter in the NORAC hydraulic manifold (PT# 104827) annually.
