How do I thread my machine? (For models equipped with the needle threader)

Upper threading (For models equipped with the needle threader)

(1) Spool pin (2) Thread guide (3) Mark on the handwheel

Make sure you thread the machine properly. Otherwise, the thread could tangle and break the needle.

The needle threader can only be used with home sewing machine needles size 75/11- 100/16. Check the table (Needle types and their uses) on the operation manual for the appropriate needle and thread combinations. If you are using transparent nylon monofilament thread, you can only use needles in the range of 90/14-100/16.
You cannot use the needle threader if you are using decorative threads or special needles, such as the twin needle and wing needle. If you are using those types of threads or needles, thread the eye of the needle by hand. Make sure the main power switch is off when threading the needle by hand.

1.	Raise the presser foot using the presser foot lever.
	(1) Presser foot lever
	If the presser foot is not raised, the sewing machine cannot be threaded.
2.	Press needle position button once or twice to raise the needle.
	(1) Needle position button
	If the needle is not correctly raised, the sewing machine can not be threaded. Be sure to turn the handwheel so that the mark on the wheel points up before threading the sewing machine.
3.	Pull up the spool pin as far as possible, and then put a spool of thread on this pin.

	If the spool of thread is in the wrong place, or is set incorrectly, the thread may tangle on the spool pin and cause the needle to break.
4.	Feed the upper thread as shown in the illustration below; i) Pass the thread through the thread guide. ii) Guide the thread down and up through the groove.
4.	(1) Thread guide
5.	Pass the thread into the thread take-up lever from the right to the left. Then guide the thread down through the groove.
	(1) Thread take-up lever
	If the thread take-up lever is lowered, the upper thread cannot be wrapped around the thread take-up lever. Make sure you raise the presser foot lever and the thread take-up lever before you feed the upper thread. If you incorrectly feed the thread you may cause sewing problems.
6.	Put the thread behind the needle bar thread guide above the needle.
	(1) Needle bar thread guide
	The thread can easily be passed behind the needle bar thread guide by holding the thread in your left hand, then feeding the thread with your right hand.
7.	Lower the presser foot lever.
