9.2.2

Hydraulic System Pressure Protection

Besides the HI-LOW Pressure Control Valves, the hydraulic system
pressure is limited by the main relief valve (3). The operating hydraulic
pressure is indicated by hydraulic gage (4).

Pressure Adjustment

Hyd. Pressure Bar (psi)

Control Valve Increase Decrease Maximum

NOTE

Do not adjust the HI pressure control to pressures greater than
207 bar (3,000 psi). Doing so will cause the main relief to open
limiting hydraulic pressure to 234 bar (3,400 psi). Excessive
opening of the main relief valve will result in significant wasted
heating of the hydraulic oil, and the decrease of water flow
performance.
