Threading the lower thread Before setting the bobbin case, remove the power plug from the outlet. Not doing so could cause an injury. Attention Use a TOYOTA-exclusive bobbin. Take out the bobbin case. (refer to P. 12 [Taking out the bobbin]) The thread must flow off the bobbin in the direction of the arrow, and then insert the bobbin into the bobbin case. Hold the end of the thread in your right hand and pass it through the groove in the bobbin case. (Pass the thread from 1 to 2) Press the bobbin with the finger of your left hand, and then pass the thread through the tension spring as shown in the diagram. (Pull until there is a locking sound. ) Turn the handwheel to move the needle to the highest position. Holding the latch of the bobbin case, insert the bobbin case into the shuttle race. Raise the presser foot and pull out the fabric to the rear. 25 Sewing Thread cutter on the needle bar * The thread cutter may differ from model to model. Line up two threads and cut with the thread cutter on the needle bar. Thread cutter on the face cover * The thread cutter may differ from model to model. Line up two threads and cut with the thread cutter on the face cover. Reverse sewing Reverse sewing is performed at the beginning and end of sewing to prevent the thread from unraveling. Stitch 1 to 2 cm from the edge of the fabric to prevent unraveling at the start of sewing. Note : Remove your finger from the reverse sewing lever to return to forward direction sewing. 26 Sewing Sewing thick fabric When sewing thick fabric from the edge, the presser foot may tilt and be unable to feed through the fabric. Place fabric or thick paper of the same thickness as the fabric you wish to sew under the presser foot. This will enable smooth sewing. Sewing thin fabric Sewing is easier if thin paper is laid out under the fabric. 27 Sewing Sewing tube-shaped fabrics Pull out the extension table (accessory box) in the direction of the arrow. Sew tube-shaped fabrics such as trousers or sleeves. 28 Sewing 2. Zigzag sewing There are various types of zigzag sewing methods, such as applique and overcastting. Turn the handwheel towards yourself to raise the needle. Adjusting thread tension Before adjustment, check again that "P. 16 [Threading the upper thread]" has been performed correctly. Adjustment method for upper thread tension Upper thread is tight Upper thread is loose Turn down the upper thread tension dial. Turn up 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. (Please refer to P. 46) Note: When the bobbin case tension is correct: the thread should slide down with light resistance. [. . . ] Doing so could cause discoloration or cracking. Release the presser foot, and use the needle plate screw driver to release the needle plate. Remove thread waste and dust with a brush (Optional accessory). Remove the bobbin case. 46 Maintenance Open the left and right stoppers to the outside. (in the direction of the arrow. ) Take out the shuttle hook cover. Take out the shuttle hook.
