4 Hydraulic Installation
Ensure all pressure has been bled from the system before disconnecting any lines
or fittings. Hydraulic pressure will exist on the main lift circuit unless the main lift
is all the way down.
Component failure due to oil contamination is not covered under the NORAC
UC4.5 system warranty. It is recommended that a qualified technician perform the
hydraulic installation.
4.1 Expansion Block Assembly
1. Use Figure 1 as a reference for installing the hydraulics.
2. Loosen the existing 2-station valve block so that it can be moved and/or twisted for the
installation of the expansion block.
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.

bolts.
