2. Maintaining a firm pressure with your thumb on the string while cradling the pin in the crook of your fingers. With your right hand, slowly begin to turn the crank in a clockwise direction with 3 turns.


3. Let the pin rotate freely in the crook of your fingers. Push hard on the wire to avoid having the becket pop out of the eye of the pin. If this hurts your thumb, you might consider wearing cloth or leather work gloves. Some technicians wear gloves as a matter of course to avoid getting oil from their skin on the string.


4. When removing from the eye of the pin inserting a small flat-bladed screwdriver under the first turn of the coil in next to the becket, and levering the string out of the eye.
