Binding method: When binding, rotate the presser foot handwheel clockwise to lift the presser foot, put the binding material into the presser foot, release the presser foot handwheel at the selected position and press it automatically, then rotate the presser foot handwheel counterclockwise to lock ~ 180, and then rotate the sewing handle counterclockwise to sew the needle through the material. When the thread is in place, the guide arm will automatically hang the thread in the slot of the sewing hook, and the handle will be lifted up at this time. At the same time, the sewing thread will pass through the binding material, and then loosen the presser foot handwheel clockwise to complete one-stitch binding. Repeat the above steps to complete the binding task immediately. Needle insertion method: loosen the fixing screw on the needle buckle, remove the needle buckle, hang the hook at the end of the needle buckle into the fixing hole of the needle buckle, keep it vertical, put the needle buckle in its original position, and tighten the fixing screw on the needle buckle. /viewthread.php？ tid=89477
