Using the Jokari Secura 2AK - T20100 wire stripper is a breeze. First, place the wire you want to strip into the appropriate opening. You don't need to adjust the diameter, so it's simple to get started. For the length of the stripped part, use the adjustable length stopper to set it anywhere from 6 to 18 mm according to your needs. When stripping, hold the tool firmly by its soft, non - slip safety grip. If you need to cut the wire, this tool can handle diameters up to 2.5 mm². Just place the wire in the cutting area and apply pressure. Regarding maintenance, since the blades are exchangeable, when they become dull, you can replace them easily to keep the tool in top condition. Also, adjust the cutting depth for different conductor insulation materials to ensure a clean strip. Always store the tool in a dry place to prevent rusting. And remember, as it's TÜV / GS approved, you can trust its quality and safety during use.
