IMPORTANT ● This packing material is designed to prevent damage in transit. ● Save this packing material in case it is needed to transport this sewing machine. Bobbin case tension adjustment The bobbin thread tension has already been adjusted at the factory for general use. For most sewing applications, no adjustment is needed. When sewing with thin thread on thin fabrics, the thread tension may not be adjusted adequately with the upper tension control dial. Therefore, the thread tension must be adjusted according to the procedure described below. Note ● If the loops still appear on the surface of the fabric after you adjust the upper tension, the bobbin thread may be too loose. In this case, turn the screw clockwise, being careful not to over-tighten the screw, approximately 30-45 degrees to increase bobbin tension. After you adjust the bobbin thread, adjust the upper thread to match the bobbin thread. a Screw 48
