4.2.2 Hydraulic System
Checking Hydraulic Pressure
To make sure that sufficient hydraulic pressure is
applied to the hydraulic cylinder locking sleeve:
1. Install a 0 to 5000 psi gauge at the upper port of
the hydraulic cylinder.
2. When holding the HOLD TO OPERATE button,
check the pressure reading. Pressure must be
3700 - 4500 psi.
3. If pressure is less than 3700 psi, check for air and
hydraulic leaks between the hydraulic pump and
the cylinder. Make sure that the secondary air
pressure supply is 60 - 65 PSI.
4. Remove the gauge installed in step 1.
Bleeding Air from System
4. Add oil to intensifier reservoir, if necessary, (see
Section 4).
NOTE:
Gauge port is the same as bleed port
for locking circuit.
5. Use 3/16 inch hex to “crack” plug at gauge port.
6. Press and hold the “HOLD TO OPERATE” button
and let some fluid flow past the loosened plug.
7. Allow air to escape through port until oil flows
freely.
8. While oil flows, tighten plug. Release the button.
9. Replenish oil in the reservoir immediately after
bleeding.

* If troubles with the flowmeter and main printed circuit board prove difficult to isolate, follow the isolation
procedure listed in Section 4.2.6.
** When replacing a printed circuit board, replace both the main printed circuit board and the display board.
