Using the Klein Tools 53837 knockout punch is quite simple. First, position the punch where you need to make a hole on the 1 - inch EMT conduit or other suitable materials like aluminum, fiberglass, or plastic. Then, use a wrench to apply pressure. The punch is designed to reduce the effort you need to put in. When you're done punching, the split slugs inside will make it easy to remove them from the punch. As for maintenance, keep the punch clean after each use. You can wipe it with a dry cloth. Since it has a black oxide finish, avoid using harsh chemicals that might damage this protective layer. Also, store it in a dry place to prevent rusting. Just follow these steps, and your punch will serve you well for a long time.
