Turn the handwheel towards yourself to raise the needle. Turn the pattern selection dial to choose the pattern. Set the fabric and lower the presser foot. Step on the foot controller to begin sewing. Adjustment method for upper thread tension Upper thread is tight Upper thread is loose Turn down the upper thread tension dial. Note : If the tension does not change even when you turn the upper thread tension dial, reset the upper thread. Note : If it does not change with the upper thread, adjust the lower thread. Adjustment method for lower thread tension Adjust by turning the bobbin case adjustment screw with the accessory screw driver. Turn right to tighten the tension Turn left to loosen the tension After adjusting the tension of the bobbin case, suspend bobbin, bobbin case, and shuttle hook all together and hold the bobbin thread as illustrated. 46) Note: When the bobbin case tension is correct: the thread should slide down with light resistance.
