A.
ALIGNMENT AND REMOVAL OF PUNCHES AND DIES:
WARNING: Failure to properly align punches and dies can cause serious bodily injury to
personnel and/or damage to equipment. Please read carefully and understand the following
method. It will also be helpful to refer to the safety dvd provided for a visual reference. If you did
not receive a safety CD, please contact your dealer or the factory. FOR PARTS
IDENTIFICATION, REFER TO FIGURE 8.
Move all tooling to the back of the tool table and crank the bar shear hold-down to the "DOWN" position
when punching. Failure to move the Angle Shear, Channel Shear, Brakes, etc. out from under the upper
arm can result in possible danger to other personnel and damage to the tools.
1.
With the machine in the PUNCH position, turn the machine’s electrical power off at the
disconnect switch.
2.
Release the stripper and swing it to the side.
3.
Loosen the die holder bolts (B).
4.
Loosen and remove the punch retaining nut (A). Set the punch retaining nut and punch aside.
5.
Loosen the two set screws (D) holding the die insert (C). Remove the die insert and loosen the bolt
holding the die and remove the die.
NOTE: The die insert has an alignment dowel pin in it
and must be lifted to remove it.
CAUTION: IF YOU ARE USING THE OFFSET DIE
HOLDER FOR FLANGED PUNCHING, PLEASE SEE SPECIAL INSTRUCTIONS IN
SECTION 7.9B BEFORE CONTINUING.
6.
Place the disconnect switch in the ON position and the selector switch in the START position.
Power the machine by pressing the green START button.
7.
Check to make sure that there are no objects (such as tools) on or under any of the moving parts.
8.
Place the selector switch in the SHEAR position and allow the ram to extend.
9.
Turn the machine's power off.
10.
Clean the die insert cavity of any foreign material.
11.
Select the proper punch and die. Make sure that there is proper clearance between the punch and
die. For recommended clearances, SEE PARAGRAPH G IN SECTION 6.1.
12.
Clean both the punch and die.
13.
Insert the proper die in the die insert (C). (If the die has a flat spot in it, align this with the bolt in
the die holder.) Tighten the bolt firmly with a wrench.

Insert the punch into the punch retaining nut (A). Make sure that it seats properly. Place the
punch retaining nut assembly on the die insert, with the punch inserted in the die.
NOTE: Please note that all of our shaped punches, including squares, ovals, hexagons and special
order punches, are manufactured with a keyed alignment system. The keyed slot mates with the
slots in the punch ram, to allow two positive locked positions for the punch.
15.
Place the insert back in the die holder and tighten the set screws (D).
16.
Raise the punch retaining nut and turn it on to the punch ram. (The die holder may have to be
moved slightly to align the punch retaining nut to the punch ram.)
