1. Turn the tuning knob clockwise until the string hub ejects from the tuner housing. A click or snap will be heard as the hub ejects to its stop point. Continue turning in this direction about two full turns after you hear the click. (You may feel some initial resistance at this point. This is normal.) This will disengage the string lock system.

2. Thread the string through the passage. While the string is pulled taut, turn the tuning knob counterclockwise until you feel the string lock system clamp the string into the hub. See FIG.4.
