Using your Klein Tools 50402 cable bender is a breeze. First, check the cable size to make sure it's within the 500 MCM maximum capacity. Place the cable into the tool opening. Then, hold the contoured handle firmly and start bending the cable. For easier bends, it's a good idea to use two benders. When not in use, store the bender in a dry place to prevent corrosion. If it gets dirty, simply wipe it down with a clean cloth. Avoid using excessive force that could damage the tool or the cable. That's all there is to it! Enjoy using your reliable cable bender.
