Using your Klein 63314 bolt cutter is easy. Just place the material you want to cut between the jaws and squeeze the handles firmly. The flat - ended vinyl grips make it simple to make 90 - degree cuts when needed. When using, make sure the material is within the specified cutting capacities. For soft and medium materials, it can handle up to Brinell 300 and Rockwell C31, and for hard materials, up to Brinell 400 and Rockwell C42. As for maintenance, after each use, wipe the jaws clean to prevent rust and debris build - up. If the cutting performance declines, you can replace the blade with the 63814 replacement blade. Store the bolt cutter in a dry place to keep it in good condition.
