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.
