INTRODUCTION
Thank you for choosing Carpenter Mfg. Co. Inc. Wire Processing Equipment.
For over 60 years Carpenter has been a leader in Wire Processing Technology
and Service. Our desire has always been to bring you reliable products.
We look forward to a long healthy relationship with you and our company. The
MODEL 72D can process a wide range of cables as referenced on the following
page.
These processing specifications are based upon the most commonly manufactured
cables. Special applications may arise with cables that are within the
specification limits of the machine but are very difficult or unsuccessful to
process. Likewise, cables that exceed the specified limits of the machine can
sometimes be processed. Because there are many variables involved in Wire
Processing we strongly recommend a free Wire Evaluation at our factory
followed by a demonstration from a Carpenter representative to ensure the
ultimate success of your Wire Processing Application.
This operating manual explains how to operate the MODEL 72D.
To ensure the best performance of your machine, read this manual carefully
until you familiarize yourself thoroughly with its operation and features.
After you have read through the manual, keep it available for reference.

MACHINE SET UP
Turn push plate stop nut to vertical position and swing push plate down
exposing faceplate. Slip wire guide into the faceplate. Re-latch push plate.
Push Plate Adjustment: Avoid wire guide contact with a blade in a relaxed
position by setting push plate stop nut to permit 1/16” clearance between wire
guide flange and push plate at-rest position.
Blade Adjustment: Slide Safety Guard backward. Loosen blade block locking
screw #1758. Set blades to conductor Bthickness. To adjust blades “in”,
turn blade adjusting screw #2711 clockwise; to move blade “out”, turn
counter-clockwise. Re-tighten blade block locking screw #1758. Return
Safety Guard to the closed position.
MACHINE OPERATION / TRIAL STRIP
TRIAL STRIP
Adjust stop rod to strip length desired by loosening thumbscrew #3877 located
at the rear of the machine. The stop rod collar is used to offer a larger
target when long strips are being utilized. Turn unit on.
Steps:
A. Depress push plate with one hand, allowing blades to open just enough to
insert the wire.
B. With another hand, insert wire through wire guide to stop rod (adjusted for
strip length).
C. Allow blades to close completely on wire by slowly removing pressure on
push plate and withdrawing wire slightly as blades grip and sever insulation.
D. Pause momentarily with hand-off push plate.
E. Withdraw wire sharply.
Note: Cycle time may be shortened as the technique is perfected.
Final Blade Adjustment: If blades contact conductor, move blade adjusting
screw #2711 counter-clockwise. If slug has not been removed, turn clockwise.
Cut off trial strip and repeat if necessary. Make certain to always re-tighten
blade block locking screw #1758 after having made blade adjustments.
NEVER INSERT ANYTHING BUT INSULATED WIRE INTO THE FACEPLATE OR BLADE DAMAGE MAY OCCUR.
BLADE CHANGE / CENTERING BLADES
Blades are factory centered, re-center only after new blades have been
installed.
When installing new blades and/or centering blades the faceplate must be
removed. Turn the machine off and unplug. Slide Safety Guard backward and un-
hook drive belt. Loosen faceplate set screw #1481 and push faceplate out the
back of the machine.
CENTERING BLADES
Un-hook blade block spring #2710, loosen centering lock screw #5395, and
blade block lock screw #1758. Insert a centering gauge (supplied with
machine) through the faceplate in the same manner as you would a wire guide so
that a small diameter of the gauge is between blades. Then turn the blade
adjusting screw #2711 until both blades make contact with the centering
gauge. Tighten blade block lock screw #1758; turn to center screw
#2848 to contact blade adjusting screw #2711; tighten centering lock
screw #5395. Re-hook blade block spring, loosen blade block lock screw and
turn blade adjusting screw counter-clockwise to allow the centering gauge to
drop out. Re-tighten blade block lock screw. Re-install faceplate by turning
until grooved section is aligned with faceplate set screw. Hook up drive belt.
Return Safety Guard to closed position.
BLADE SPRING CHANGE
Before installing new blade springs #2710, bend spring as shown for the left and right side.
