Trace the arrows with design. d Once the design is transferred to the stabilizer, position the fabric under the free-motion presser foot on the machine, and then use free- motion sewing to sew the design. Adjusting the Thread Tension Note • Turning the screw on the bobbin case (gray) may push up the spring plate, as shown below. If this occurs, gently press down the spring plate with a screwdriver so it is lower than the top surface of the bobbin case (gray), and then insert the bobbin case into the machine. After sewing trial stitches and checking the sewing results, adjust the thread tensions if necessary. After adjusting the tensions, be sure to sew trial stitches again in order to check the sewing results. ■ Adjusting the Upper Thread Tension We recommend an upper thread tension that is higher than the standard setting. Refer to the machine's Operation Manual for detailed instruction. ■ Adjusting the Tension of the Bobbin Thread If the desired stitching cannot be achieved after adjusting the upper thread tension, adjust the tension of the bobbin thread. The tension of the bobbin thread can be adjusted by turning the slotted-head (-) screw on the bobbin case (gray) for bobbin work. a Spring plate 11
