Using this Klein 32900 7 - in - 1 Impact Flip Socket is easy. First, decide whether you want to use it as a screwdriver or with an impact driver. If you're using it with an impact driver, connect it using the 1/4 - Inch Quick - Connect adapter. To change the socket size, simply flip the socket to the desired one. The color - coding makes it easy to pick the right size. When using it to hold fasteners, the Rare - Earth magnet will keep them in place. As for maintenance, regularly remove the detachable sockets and clean off any metal shavings that might have stuck to the magnet. Store the sockets on the shaft when not in use to keep them organized and prevent loss. Also, since it's impact - rated, it can handle the power of an impact driver, but don't use excessive force that might damage the tool.
