1. Choose an appropriate twist socket with suitable size.
2. Put the extension driver on one side of twist socket.
3. Use a manual wrench to loose the nut anticlockwise.
4. Take the extension drive out from the twist socket.
5. Use a round bar to push the nut and take out the nut of the twist socket. If the nut could not be taken out from the twist socket, then use a hammer hitting the round bar to take out the nut from the twist socket.

Note: While operating, be sure to wear protect-glass to protect eyes from nut fragment.
