144 Hydraulic System
Refer to the hydraulic pressure table to adjust each function of the lifting arm. Before performing the
procedure, make sure that all function levers and their adjustment screws have been properly
identified on the valve.
NOTE: A helper may be needed when adjusting arm pressure. Use all necessary safety precautions
around the vehicle at all times.
To adjust the proportional valve main relief pressure:
1. Secure the arm working area using safety tape or barricades.
2. Install the lever on the proportional valve to adjust.
3. Move the lever back and forth to remove any residual hydraulic pressure in the system.
4. Connect a 0–4000 psi gauge on the quick coupler located on the proportional valve.

adjustment screw. Turn the hex wrench clockwise to raise pressure, or counterclockwise to lower
pressure.
