7.5 Hydraulic Plumbing – Option 2
Hydraulic Plumbing - Option 2 allows for manual control of the Linear Roll functions through
the HC6500 joystick controls.
From this point on in the installation the booms will be inoperative until the
hydraulics are fully installed.
1. After the valves are mounted on the sprayer, the hydraulic hoses and fittings can be
installed (plumbed).
2. Install tee fittings on the “TR” and “TL” port fittings at the HARDI block.
3. Connect pressure and tank lines to the HARDI block (“P1” & “T1”). Connect the other
end of the hoses to the NORAC block.
4. Connect the “B” line hoses to “TL1” and “TR1” port fittings at the HARDI block. Connect
the other end of the hoses to the NORAC block.
5. The “A” ports on the NORAC block are plugged.
6. Install Rexroth one-way restrictors (GSU2.38.100; HARDI part number 78211900) onto the
left tilt (TL) and right tilt (RT) lines as shown in Figure 24. The restrictor should be
oriented with the free flow towards the tilt cylinder and control flow towards the HARDI
manifold.
