1. Screw the lock wheel with patented self-locking thread tool-free by hand, you already protect your guitar sufficiently (the round shaping must be facing the pull-up ball).
2. Use a 2 mm or 5/64″ Allen key or screwdriver to tighten it for maximum security.
3. Use the micro cone-top screw to attach it permanently. You will never lose your wheel again. Finally put all parts together and just listen carefully. Give it a shake, give it a roll and prepare to be amazed: It is silent.
