How to use

Secure the cable in the stripper’s jaws according to the required strip length, then rotate or actuate the tool as designed to cut and remove the insulation without nicking the conductor. Adjust your grip and the positioning of the cable to achieve a clean strip; perform a test strip on a scrap piece if necessary to confirm the correct setting. After stripping, inspect the conductor for damage before making electrical connections or splices.

Usage recommendations

Use the MM-412 for routine insulation removal tasks where manual control and portability are priorities. Regularly check the cutting edge for wear and replace or service the tool if stripping quality deteriorates. Wear appropriate personal protective equipment and follow electrical safety practices when working on live or de-energized circuits.
