FAQs & Troubleshooting

How do I thread my machine? (for models equipped with a needle threader)

(1) Spool pin
(2) Thread guide
(3) Thread take-up lever
(4) Mark on the handwheel

When threading the upper thread, carefully follow the instructions. If the upper threading is not correct, the thread may become tangled or the needle may bend or break.
Never use a thread weight of 20 or lower.
Use the needle and the thread in the correct combination. For details on the correct combination of needles and threads, refer to the section of “FABRIC, THREAD, AND NEEDLE COMBINATIONS” on the Operation Manual.
The needle threader can be used with a 75/11 through 100/16 home sewing machine needle. However, the needle threader cannot be used with a 65/9 home sewing machine needle. When using special thread such as transparent nylon thread or metallic thread, the needle threader cannot be used.
Thread with a thickness of 130/120 or thicker cannot be used with the needle threader.
The needle threader cannot be used with the wing needle or the twin needle.

Turn off the machine.
Raise the presser foot lever.

(1) Presser foot lever
Raise the needle by turning the handwheel toward you (counterclockwise) so that the mark on the wheel points up.

(1) Mark on the wheel

If the needle is not correctly raised, the sewing machine can not be threaded.
Swing up the spool pin, and then remove the spool cap.

(1) Spool pin
(2) Spool cap
Fully insert the spool for the upper thread onto the spool pin.

Slide the spool onto the pin so that the spool is horizontal and the thread unwinds to the front at the bottom.
- If the spool is not positioned so that the thread unwinds correctly, the thread may become tangled around the spool pin and the thread or needle may break.
- If the spool cap that is used is smaller than the spool, the thread may catch, for example, on the notch in the spool, or the needle may break.
Slide the spool cap onto the spool pin.

When sewing with fine, cross-wound thread, use the small spool cap, and leave a small space between the cap and the spool.

(2) Spool (cross-wound thread)
(3) Space
While holding the spool with your right hand, pull the thread with your left hand, and then pass the thread under the thread guide A.

(1)Thread guide "A"
Pass the thread under the thread guide B from the back to the front.

(1) Thread guide "B"

Hold the thread with your right hand so that there is no slack in the thread that is pulled out, and then pass the thread under the thread guide B with your left hand.
Thread the machine by guiding the thread along the path indicated by the number on the machine.
Make sure you guide the thread through the thread take-up lever from right to left as shown in the following illustration.

(1) Thread take-up lever

If the thread take-up lever is lowered, the upper thread can not be wrapped around the thread take-up lever. Make sure you raise the needle by turning the handwheel toward you (counterclockwise) so that the mark on the wheel points up.
Put the thread behind the guide above the needle.

(1) Needle bar thread guide
Lower the presser foot lever.

(1) Presser foot lever
Make sure that the mark on the wheel points up as shown in the following illustration.

(1) Mark on the wheel
While lowering the needle threader lever, hook the thread onto the guide.

(1) Needle holder
(2) Needle threader lever
(3) Guide
Pull down the needle threader lever as much as possible, and then turn the lever toward the back of the machine (away from you).Make sure that the hook passes through the eye of the needle and grabs the thread.

(1) Hook
(2) Thread

Hold the thread in front of the needle to make sure that the hook grabs it.
While lightly holding the thread, turn the needle threader lever toward the front of the machine (toward you). The hook will pull the thread through the needle.
Raise the needle threader lever.
Pull the loop of the thread passed through the eye of the needle toward the rear of the machine.

(1) Loop of thread

Be careful not to pull on the thread with force or it may bend the needle.
- If the thread does not pass through the eye of the needle, start from step 13 again.
- Needle threader cannot be used when using the twin needle. In this case, thread the needle as described below.
Raise the presser foot lever.

(1) Presser foot lever
Pass the end of the thread through the presser foot, and then pull out about 5 cm (2 inches) of thread toward the rear of the machine.

(1) 5 cm (2 inches)

If you incorrectly feed the thread you may cause sewing problems.
