Using this Klein cutting jaw is simple. First, make sure it's properly attached to your BAT207T battery - operated cable cutter. When you're ready to cut, place the copper or aluminum cable within the cutting area. Just activate the cutter, and the 7 - ton hydraulic force will do the job with 15% more power. As for maintenance, regularly check the blades. If they're worn out, you can easily replace them. Also, keep the jaw clean to ensure smooth operation. Be careful when handling the cutter to avoid any accidents. Always follow the safety instructions provided with your cable cutter.
