HYDRAULIC INSTALLATION
WARNING!
The hydraulic system creates very
high pressure. Before disconnecting
any hydraulic lines ensure all pressure
has been bled from the system.
IMPORTANT:
Component failure due to oil
contamination is not covered under
the UC4+ Spray Height Control
system warranty. It is recommended
that a qualified technician does the
hydraulic installation.
Sprayers with a model year of
2007 and older require the main
lift valve to be changed. See
Section 4 for instructions on how
to do this.
1. Use Figure 1 as a reference for
installing the hydraulics.
2. Install the 6MB 6MOR fitting (F04) into
the A and B ports of the expansion
block (Figure 2).

3. Remove the four 4MBP plugs from the 2
station valve block.
4. Coat the four o-rings in hydraulic oil
and install them into the expansion
block. Ensure the o-rings are seated
properly.
5. Attach the expansion block to the 2
station block using the included spring
washers and bolts.
6. Tighten the bolts to 31 ft-lbs.
