Read, understand and follow all safety instructions and
operating procedures. If you do not understand the
instructions or if conditions are not correct for proper
operation, do not operate the machine. Consult your
supervisor or other responsible person.
*Check that the trigger switch is not locked on.
*Check that the manual return valve is closed.
*Make sure that the proper punch and die are installed
correctly. See
Die Selection
and
Proper Punches and
Dies
in this Manual
*If you are using the hole locator gage, adjust it to the
proper distance. See
Hole Locator Gage Adjustment
in
this manual.
*Plug the power cord into the proper power supply.
OPERATING PROCEDURES
*Position the puncher at the proper location on the
workpiece using the hole locator gage or by locating the
point on the end of the punch into a center punch mark on
the piece.
With everything in proper order, the switch can be activated
to start the electric motor. The punch piston will move out
and push the punch through the material. Keep the switch
on until the punch has reached the end of its stroke and
stops. Release the switch. The automatic return valve will
open at the end of the stroke allowing the punch piston to
retract to its home position. The punch piston must return
completely before another hole can be punched.
If the punch stops in the midst of its stroke or does not
come out of the material, open the manual return valve.
Once the punch piston has returned to its home position,
tighten the manual return valve.
Although the foot switch is guarded against inadvertent
operation, it is best to position the foot pedal away from
normal standing position. Place it in a position that
requires deliberate effort to reach and activate the switch.
The trigger switch should be locked on only when ready
to punch. Release the trigger switch immediately after
punching to prevent operation by inadvertent actuation of
the foot switch.

The Hole locator Gage can be set to hold the Hole
Punches at a constant distance from the edge of the
workpiece. The gage is held in place by one or two socket
head caps screws. Before making any adjustment,
first, unplug the power cord. To adjust the position of the
gage, loosen the cap screw(s), tap the gage into the
desired position and retighten the cap screw(s).
HOLE LOCATOR GAGE ADJUSTMENT
All models can be used with an accessory work stand for
bench or table mounting of the Hole Puncher. The stand
is standard with all models. To install the stand, first
unplug the power cord., then mount the unit to the stand
with the supplied hardware.
When using the stand, periodically check to make sure that
the punched material (slugs) are not stacking up between
the exit hole in the “C”-frame and the stand. Keep this area
clear of accumulated slugs.
USING THE WORK STAND
SELECTING PROPER DIES
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
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.
