KNOWING YOUR SEWING MACHINE
■Twin Needle Threading
You should thread each needle separately.
1Threading the Right Needle
Follow the same instructions for threading a single needle. See page 18 for more details.
2Threading the Left Needle
Thread the left needle in the same way that you threaded the right needle using the thread from the spool on the extra spool pin, but do not pass the thread through the thread guide above the needle before you pass it through the eye of the left needle.

Note
Models that are equipped with a Needle Threader
●You cannot use the needle threader to thread the twin needle. Instead, thread the twin needle by hand, from front to back. Using the needle threader may damage the machine.
Tension of the Thread
The tension of the thread will affect the quality of your stitches. You may need to adjust it when you change fabric or thread.
Memo
●We recommend that you sew a scrap piece of fabric to check the thread tension before sewing on your project.
●The basic thread tension setting is “5”.
■Possible Problems If the Tension Is Wrong
Upper tension is too tight.
Locks will appear on the surface of the fabric.

Decrease the tension by turning the dial to a lower number.

Note
●The lower thread tension has 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 cannot be adjusted adequately with the upper tension control dial. Instead, the thread tension must be adjusted according to the procedure described below.
Lower tension is too loose.
Locks appear on the surface of the fabric. Decrease the thread tension by turning the dial to a lower number. If the result is still not satisfactory, then adjust the bobbin thread tension as explained below.
Bobbin
Increase the tension in the bobbin by turning the screw with a small screwdriver in a clockwise direction. However, do not turn the screw more than one full turn.
Remember to return the screw to its original position before starting your next project.
