the die to verify the punch enters the die with
clearance around the total perimeter. DO NOT
allow the punch to contact the die in any way.
Should contact occur, verify that the correct
punch and die are matched together or that the
punch and die are aligned. Square and Oblong

8.2 Center station change
Referring to Figures 8 - 11:
Tools required for assembly:
5/8” open-end wrench
3/4” open-end wrench
9/16” socket wrench with extension
The center station is fitted with the flat/angle shear
station as standard. An optional punch station may
be installed in place of the shear station.
This procedure will require the
ironworker to be powered on to change the
position of the rocker arm. ALWAYS disconnect
power to the machine before performing the
steps when the rocker arm is to be stationary.
Failure to do this may result in serious personal
injury.
1.
The cylinder should be in the retracted position.
If not, power the ironworker On and press the
cylinder retract pedal to fully retract the cylinder.
2.
Disconnect the ironworker from the power
supply.
3.
Remove the blade to rock arm pivot bolt (Fig. 8,
A).
4.
Remove and retain the four bolts (Fig. 8, B)
mounting the shear station to the frame table.
5.
Power the ironworker On and press the cylinder
extend pedal to raise the rocker arm away from
the shear blade.
