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 table "Combination of fabric, thread and needle".
-
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 on the sewing machine.
-
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 correctly.
-
Press
(needle position button) once or twice to raise the needle.
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.(1) Mark -
As shown, press down on the spool pin lever with your finger.

(1) Spool pin
(2) Spool cap
Be sure to raise the spool pin before use.
If thespool 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. -
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.
-
Slide the spool cap onto the spool pin.
With the slightly rounded side of the spool cap positioned toward the left, slide the spool cap onto the spool pin as far as possible to the right so that the spool is moved to the right end of the spool pin.
- If the spool or the spool cap is not positioned correctly, the thread may become tangled around the spool pin or the needle may break.
-
Three spool cap sizes are available, allowing you to choose a spool cap that best fits the size of spool being used.
If the spool cap is too small for the spool being used, the thread may catch on the slit in the spool or the needle may break.
When sewing with fine, cross-wound thread, use the small spool cap, and leave a small space between the cap and the spool.
(1) Spool cap (small)
(2) Spool (cross-wound thread)
