Sewing machine—bobbin pin issue The bobbin pin in the center of the hand wheel can be rotated counterclockwise (toward you) or held and the hand wheel can be rotated slightly in a clockwise direction to extend it. Likewise, when you’re finished, it can be pushed in and turned clockwise (or hold it and turn the handwheel counterclockwise).
