Using your Klein 63130 bolt cutter is easy. First, select the material you want to cut. Make sure it falls within the cutting capacity limits (up to Brinell 300, Rockwell C31 for soft and medium materials, and up to Brinell 400, Rockwell C42 for hard materials). Position the material between the center - cut jaws. If you need to make a 90 - degree cut, use the flat ends of the vinyl - gripped handles. For precise cutting, you can make one adjustment to realign the cutting edges. When not in use, store the bolt cutter in a dry place to prevent rust. If the cutting edges get dull, you can replace the blade with the 63930 replacement blade. Also, check the lockplate regularly to ensure the jaw bolts are tight and the jaws are in correct alignment.
