KNOWING YOUR SEWING MACHINE Drawing up bobbin thread  Raise the presser foot and hold the needle thread lightly with your left hand.  Turn the hand wheel slowly towards you with your right hand until the needle goes down and continue turning the hand wheel until the take-up lever is at its highest position. Lightly draw up the needle thread, forming a loop of the bobbin thread.  Pull 15cm (6 inches) of both threads back and under the presser foot. Balancing top thread tension The top thread and the bobbin thread should interlock in the center of two layers of fabric in straight seams. Set the desired number of the thread tension dial at setting mark. Tighten the needle thread tension by moving the dial to a higher number. Loosen the needle thread tension by moving the dial to a lower number. NOTE: In order to obtain better zigzag stitches, the top thread tension should be slightly looser than the bobbin thread tension. That means the top thread should appear slightly on the reverse side of the fabric, but the bobbin thread should not appear on the top side of the fabric. 9
