Then, close the tool to remove the insulation. When cutting wires, place the wire in the cutting area and squeeze the handles firmly. To loop or bend wires, use the dedicated holes on the tool. When it comes to maintenance, keep the tool clean after each use. Wipe off any dirt or debris with a dry cloth. Avoid using the tool in wet conditions as it's not insulated. Store it in a dry place with the closure lock engaged for safe keeping. With proper use and maintenance, this tool will serve you well for a long time.
