7.Use the spanner wrench to fully tighten the punch assembly onto the pressure plate.

8.Insert the die into the punch bolster with the larger opening down, but do not tighten the set screws (see Figure 22).

9.Set the controls to Punch and Inch, then reconnect the machine to power.

10.Turn the machine ON, press the foot actua- tor to bring the punch near—but not into—the die, then stop the motor.

11.Press the emergency stop button to avoid unexpected movement of the tooling.

12.Align the die with the punch, then tighten the set screws on both sides of the punch bolster to hold the die in place.

Note: If you have difficulty aligning the punch with the die, you may have to reposition the punch bolster. Use a 19mm wrench to loosen the bolster mounting hex bolts (see Figure 23), move the bolster and die into alignment with the punch, then re-tighten the hex bolts.

13.Properly re-position the stripper and safety guard assembly, reset the emergency stop button, then continue to jog the punch toward the die.

Note: Be prepared to quickly lift your foot from the pedal actuator to stop the punch if you suspect a mis-alignment or other prob- lem.

14.Set the controls to Normal, then move the punch in and out of the die several times to ensure proper operation of the tooling before mounting a workpiece onto the table.

To avoid tooling or workpiece breakage and the risk of possible injury to the operator, never attempt to cut a workpiece that is not adequately supported and held in place. Never attempt a cutting operation that is beyond the capacity of your machine.
