Using the Klein 2100 - 9 Cable Splicer Snip is easy. Just place the 19 AWG or 23 AWG wire, cable, or cordage between the blades and squeeze the handles. The free - fall feature helps you make quick cuts. When using, always wear safety goggles to protect your eyes from any flying debris. As for maintenance, after each use, wipe the blades with a clean, dry cloth. If the blades get dirty, you can use a mild cleaner and then dry them thoroughly. Also, keep the tool in a dry place to prevent rust. The scraper and file on the blades can be used for other small tasks, but don't use them on extremely hard materials as it may damage the tool.
