If symptoms of poor performance develop, the following chart can be used as a guide to correct the problem.

When diagnosing faults in operation of the control valve, always check that the high-pressure hydraulic power source is supplying the correct hydraulic flow and pressure to the control valve. Use a pressure gauge known to be accurate. Check the flow with the hydraulic fluid temperature at least 80 °F/27 °C.
