Using the Klein 11045 wire stripper/cutter is easy. First, identify the wire gauge you're working with. The tool has clear markings on both sides to help you find the right stripping hole. Insert the wire into the appropriate hole and squeeze the handles. The spring - loaded action will make it open automatically after use. For looping or bending wires, use the dedicated holes on the tool. When using it in tight spaces, the narrow nose design will be very helpful. As for safety, always wear appropriate safety gear like gloves and goggles. Avoid using the tool on wires outside the 10 - 18 AWG solid wire range. To keep the tool in good condition, wipe it clean after each use to remove any debris. The black - oxide finish resists corrosion, but it's still a good idea to store it in a dry place.
