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.
1. Use Figure 1 as a reference for
installing the hydraulics.
2. On a clean surface remove all plastic
plugs from the NORAC expansion valve
block (V01).
3. Install the 6MBP (F09) into the A port
of the expansion block (Figure 2).
4. Insert the orifice (F08) into the B port
of the expansion block (Figure 2).
The orifice is not required for
installation on a John Deere 4930.
5. Install the 6MB 6MOR fitting (F05) into
the B port of the expansion block

6. Coat the four o-rings in hydraulic oil
and install them into the expansion
block.

properly seated.
7. Attach the expansion block to the 2
station block using the included spring
washers and bolts.

on the sprayer, install it as outlined in
the UC4+ Spray Height Control kit
installation manual.
