Using the Klein 1006 tool is simple. First, select the right non - insulated terminal or connector that fits within the 10 - 22 AWG range. Place it in the crimping area of the tool and squeeze the handles firmly. For cutting wires, put the wire in the specially hardened cutter at the nose and press down. When using this tool, always make sure your hands are dry and clean to avoid any slippage. Also, don't try to crimp or cut materials outside the 10 - 22 AWG capacity as it may damage the tool. To maintain this tool, after each use, wipe it down with a dry cloth to remove any debris. You can also apply a light coat of oil to the moving parts occasionally to keep it working smoothly. Store it in a dry place to prevent rusting.
