Using the Klein Tools 63047 cable cutter is easy. First, select the cable you need to cut and make sure it's within the cutter's capacity. Place the cable between the jaws, then firmly squeeze the handles. The replaceable hook - jaw blades will grab and hold the cable, and the shear - cutting action will make a clean cut. Remember, this cutter is not for steel or ACSR cables. When not in use, keep it in a dry place. For maintenance, check the heavy - duty pins in the head regularly. If the blades become dull, you can replace them with the 63110 replacement blade. Also, wipe down the cutter occasionally to keep it in good condition.
