Introduction
Thank you for choosing Carpenter Mfg. Co., Inc. for your wire processing equipment needs. For
over 70 years Carpenter has been a leader in wire processing technology and service. As an
independently-owned, third generation company our philosophy has always been to provide the
customer with both quality products and outstanding service. We look forward to a long, healthy
relationship with you and our company.
The Model 420 Compu-Cut® can process a wide range of material, as referenced on the
following pages. These processing specifications are based upon the most commonly
manufactured materials. Special applications may arise with materials that are within the
specification limits of the machine but are very difficult or unsuccessful to process. Likewise,
materials that exceed the specified limits of the machine may sometimes be processed
successfully. Because there are many variables involved in wire processing, we strongly
recommend a free material evaluation, to be completed at our factory
(http://carpentermfg.com/wire-evaluation/). A demonstration from a Carpenter representative is
also recommended to ensure the ultimate success of your material processing application.
This operator’s manual explains how to operate the Model 420 Compu-Cut®. 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.
Use this manual as a quick and handy reference tool for clarifying any questions that may arise.
If you have any questions about this machine or service please let us know. Our phone number
is [phone]; we may also be reached by fax at [phone]. Visit our website
(www.carpentermfg.com), or contact us via email ([email protected]).
Carefully unpack the Carpenter Model 420 Compu-Cut®. We recommend that you keep the
original box and packaging as it will protect the machine for future transportation, if necessary.

Section 3 –Safety Guarding & Material Exit Chute Assembly
Installation
Machine Safety Guard
The Model 420 is equipped with a safety guard. The PN 8292 guard assembly contains a safety
interlock switch. The machine will not operate unless the safety guard is installed and in the
closed position.
Do not attempt to defeat the function or purpose of the safety interlock switch. Serious injury to
the operator’s eyes, fingers or other body parts may result from attempts to operate this
equipment with the machine safety guard in the raised position.
Note: If the safety guard is not in the closed position when the machine is powered on,
“PLEASE CLOSE GUARD THEN PRESS ENTER”.
Material Exit Chute Assembly
The Model 420 is equipped with a material exit chute assembly. The material exit chute
assembly contains a safety interlock switch. The machine will not operate unless the material
exit chute assembly is attached to the Model 420.
Do not attempt to defeat the function or purpose of the safety interlock switch. Serious injury to
the operator’s eyes, fingers or other body parts may result from attempts to operate this
equipment with the material exit chute assembly removed from the machine.
Follow the below steps to properly install the material exit chute assembly onto the Model 420:
1. Insert the PN 3926 material exit chute assembly dowel pin into one of the material exit
chute assembly alignment holes located on the PN 6495 front support.
2. Insert PN 6024 guard chute adjustment knob assembly into the PN 6015 brass sleeve
above the dowel pin holes. Push the knob and the chute toward the machine face plate;
this will engage the spring-loaded PN 6094 chute pivot rod under the material exit chute
assembly.
3. Line up the PN 6094 chute pivot rod with the PN 7528 bronze bearing on the PN 6003
back support.
4. Push and turn the PN 6024 guard chute adjustment knob assembly clockwise until the
threads catch, then lock into position.
Note: If the material exit chute assembly is not properly installed when the machine is powered
on, the OLED display will read “PLEASE INSTALL CHUTE THEN PRESS ENTER”.
