REMOVING AND INSTALLING PUNCHES
Prior to removing a punch, jog the punch piston down
until it puts pressure on a piece of material that is of the
appropriate thickness. With a pin spanner, loosen the
retaining nut. Manually release the punch piston with the
manual release valve, disconnect the unit from the power
supply and then remove the retaining nut and punch.
Prior to installing a different punch, check for debris in the
retaining nut and punch piston. Clean if necessary. Prior to
installing a punch, verify the "O" ring on the punch piston is
clean and not damaged.
Proper die selection is essential. Other than the obvious
necessity of matching shaped punches and dies, there are
two other basic selection factors that must be considered.
The first is die clearance. Different material types and
different material thicknesses require different clearances
between the punch and die. In order to maintain the best
possible hole while remaining within the tonnage
capacity of the machine, it is essential to choose the die
with the proper clearance. The second is the die angle.
Most structural shapes can be punched with the standard

2. Unscrew the nuts and set screws
that hold the die in place

1. To make the operation easier, first remove the strippers on both sides.
2. Reference your Operators manual and remove your punch and the die.
3. Install a new punch and punch retaining nut.

IMPORTANT NOTES:
3. Pull the die up to the tip of the punch
4. Remove the die from the "C"- frame,
inclining it to remove.
Old Die
Place your punch into the retaining nut, properly
align the punch within the punch piston and hand
tighten the retaining nut. Plug in power, jog the
punch piston down until it makes contact with your
work surface. Tighten the retaining nut with the pin
spanner. Manually release the punch piston. Your
now ready to punch your material. Failure to align
your punch properly could result in serious damage
to your machine. It is not necessary to remove your
die to install the punch piston.
flat dies, but "I" -beams and most channels which
have a 2-in-12 taper require the use of special
9-1/2 degree angled dies. Car and ship channel
flanges and other structural shapes with a 2 degree
taper can be punched with flat dies. Materials with
a flange taper of less than 5 degrees can also be
punched with the flat die, however, the hole will be
slightly angled. Refer to specific information and
tables within this manual for the proper punch and
die combination.

Structural Steel. If used in harder
or higher tensile strength
materials, performance will be
impeded and serious damaged
could occur to your unit.
