Using the Jokari T20030 flat cable stripper is a breeze. First, just insert the PVC - insulated flat cable into the stripper. Since it has an unlimited stripping range and doesn't require diameter adjustments, you can strip cables of different sizes easily. Once the cable is in place, operate the stripper as you would with a regular tool. The built - in wire bending hole can be used to bend conductors up to 2.5 mm² for proper termination. When it comes to blade changing, thanks to the exchangeable cassette system, you can quickly swap out the blades. For maintenance, keep the blades clean and dry. Avoid using the stripper on cables that exceed its specified width and diameter limits. If the blades become dull over time, simply replace them using the cassette system.
