■Attaching the Twin Needle
Attach the twin needle in the same way as a single needle (see page 8). The flat side of the needle should face toward the back and the rounded side should face toward you.
■Attaching the Extra Spool Pin
Put the extra spool pin in the hole on the top of the machine. Put the second spool of thread onto the extra spool pin.
■Twin Needle Threading
You should thread each needle separately.
1Thread the left needle.
Follow the same instructions for threading a single needle (see page 21).
2Thread the right needle.
Thread the right needle in the same way that you threaded the left needle using the thread from the spool on the extra spool pin, but do not pass the thread through the guide above the needle before you pass it through the eye of the right needle.

Memo
●We recommend that you do a test sample on scrap of a fabric before you start to sew.
■Correct Tension
Correct tension is important as too much or too little tension will weaken your seams or cause puckers on your fabric.

Models Equipped with a Needle Threader
●You can not 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.
