HYDRAULIC SYSTEM FUNCTIONAL TEST Continued
Adjust the system relief valve to relieve the system pressure at 5150 PSI. Turn the sytem relief valve
adjusting screw clockwise until 5150 PSI indicates on the system pressure gage. Lock the adjustment
screw with the locknut.
Open the compensator shut off valve, turn knob counterclockwise. Adjust the system pressure with the
pressure compensator until the system pressure gage indicates a pressure of 5000 psi. Lock control
with locknut under knob.
Return the flow control valve to the BY-PASS position.
Increase the volume flow and attempt to obtain a flow of 5 GPM.
Check the hydraulic fluid temperature gage for proper operating range. Check overall system for leaks.
Adjust fluid flow to zero on the flow meter, turn control clockwise.
Place the flow control to the SUPPLY PORT position.
Open the pressure compensator until the system pressure gage indicates 500 PSI or less.
Relieve system pressure, turn adjusting screw counterclockwise three turns.
Turn throttle to the left and push fully in, let engine idle for a minute or two.
Put ignition switch in the stop position. Put the power ON/OFF switch to OFF.
