Pick a side and turn counter-clockwise until the cup is removed. Once the cup is removed off of the spindle, turn the frame over and remove the bottom bracket itself, by turning clockwise."

The spindle itself is not very deep; as a result, this tool will easily come out when putting a lot of torque on the wrench to remove the bottom bracket. Be careful not to strip the splines or threads of the bottom bracket. These parts are threaded differently, and will require some trial and error to figure out which side the lock ring is on. The lock ring will be threaded normally, and will most likely unscrew somewhat easily (relative to the other side).
