IMPORTANT: In all cases, size the spacer block so the maximum stroke of the hydraulic unit is not exceeded. Refer
to Section 3 to determine maximum stroke of your press.
WARNING: Spacer block must be centered on moving bolster (or platen). Be certain that spacer is strong enough
to withstand maximum applied force of press and that its area is great enough to prevent coining the
bolster (or platen) surface.

Close (energize) the ELECTRICAL DISCONNECT switch. Tighten the pressure release knob on the pump, close the
press and preheat the platens to the set temperature.
Hot Plates with Thermostats:
If your press is equipped with individual thermostats located in the platen, rotate the knob clockwise to increase the
temperature. Verify the temperature on the integral thermometer, and adjust the knobs accordingly.
CAUTION: On presses with thermostat control, customer is to provide short-circuit protection based upon the
electrical nameplate current draw.
Digital Platen Control Systems:
Select the [ON] position of the ELECTRICAL DISCONNECT switch, located on the front of the control panel of
presses equipped with digital, platen controller(s).
Heated presses equipped with digital controls include solid state heater contactors and digital temperature controllers.
The platen temperature is controlled with 1/16 DIN digital temperature controller(s). The controller(s) are modular and
can be removed from their mounting housing. They are preset at the factory and no field adjustment (other than the
temperature setting) should be necessary.
The control panel located on the side of the press includes, the ELECTRICAL DISCONNECT switch, POWER ON-
OFF BUTTONS and the temperature controller(s).
Adjust the digital temperature controller(s) to the desired operating temperature for your process by depressing the
[ARROW UP] or [ARROW DOWN] key on the temperature controller(s).
To shut down the press, select the [OFF] position on the ELECTRICAL DISCONNECT switch or press power off
button.
WARNING: When operating a press with heated platens, wear the appropriate personal safety gear, such as,
insulated gloves to protect arms and hands from burns.
