12. Insert an Autococker® Valve Tool into the rear of the bottom tube until
you feel it seat deeply on the Valve Retaining Nut and remove it. Because
CCM® uses a Valve Retaining Nut Set Screw; the Valve Retaining Nut is
often marred. This can make this nut a bit stiff to remove. Take your time,
make sure the tool is seated as deeply as it can be, and be careful.
