Using the Klein 66077 Flip Impact Socket is super easy. First, pick the size you need by flipping the socket. The color - coding helps you quickly find the right one. Then, attach it to your impact driver or Klein's Compact Impact Wrench. You're ready to install or remove hardware. When using it, make sure the socket is properly seated on the hardware to avoid slipping. As for maintenance, after each use, wipe the socket clean with a dry cloth. Store it in a dry place to prevent rust. If it gets dirty, you can use a mild soap and water to clean it, but make sure to dry it thoroughly before storing. Don't use it with tools that are not compatible as it may damage the socket.
