Using the Klein Tools 11063W Katapult wire stripper and cutter is easy. First, for stripping, select the appropriate stripping hole according to the wire gauge. Place the wire in the hole and squeeze the handle. The tool will grip and strip the insulation in one go. To cut the wire, use the built - in cutting hole. Just insert the wire and squeeze firmly. When using, make sure the wire is properly placed in the holes to avoid any damage to the tool or the wire. For maintenance, keep the tool clean after each use. You can wipe it with a dry cloth. Since it has a heavy - duty Ecoat finish, it's quite resistant to corrosion, but it's still a good idea to store it in a dry place to ensure its long - term durability.
