TROUBLESHOOTING
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 intensifier, always check that the hydraulic power source is supplying the correct hydraulic flow and pressure to the intensifier as listed in the table. Use a flow meter known to be accurate. Check the flow with the hydraulic fluid temperature at least 80 °F/27 °C.
