Instructions 67-9319MAINTENANCE AND TROUBLESHOOTING INJECTOR CALIBRATOR CD34.2.2 Hydraulic SystemChecking Hydraulic PressureTo make sure that sufficient hydraulic pressure isapplied to the hydraulic cylinder locking sleeve:1. Install a 0 to 5000 psi gauge at the upper port ofthe hydraulic cylinder.2. When holding the HOLD TO OPERATE button,check the pressure reading. Pressure must be3700 - 4500 psi.3. If pressure is less than 3700 psi, check for air andhydraulic leaks between the hydraulic pump andthe cylinder. Make sure that the secondary airpressure supply is 60 - 65 PSI.4. Remove the gauge installed in step 1.Bleeding Air from System4. Add oil to intensifier reservoir, if necessary, (seeSection 4).NOTE: Gauge port is the same as bleed portfor locking circuit.5. Use 3/16 inch hex to “crack” plug at gauge port.6. Press and hold the “HOLD TO OPERATE” buttonand let some fluid flow past the loosened plug.7. Allow air to escape through port until oil flowsfreely.8. While oil flows, tighten plug. Release the button.9. Replenish oil in the reservoir immediately afterbleeding.TROUBLESHOOTING CHART FOR ELECTRICAL PROBLEMS (cont.)Fault Possible Cause and Remedy_________________________________________________________________________________Flowmeter displays 1.
