4.6 H YDRAULIC I NSTALLATION
If your valve block connectors appear
different than shown, see Appendix A for
more details.
WARNING!
The hydraulic system creates very high
pressure. Before disconnecting any
hydraulic lines ensure all pressure has
been bled from the system. When
changing the boom hydraulic hoses leave
the booms in TRANSPORT POSITION.
IMPORTANT:
Component failure due to oil
contamination is not covered under the
UC4+ System warranty. It is
recommended that a qualified technician
does the hydraulic installation.

plugs from the NORAC hydraulic Valve

2. Install the orifices (F05) into the "B"
