Tangled thread on wrong side of fabric
The thread becomes tangled on the lower side of the fabric.
- After starting sewing, a rattling noise is made and sewing cannot continue.
Looking under the fabric, there is tangled thread in the bobbin case.
If the upper thread is incorrectly threaded, the upper thread passed through the fabric cannot be firmly pulled up and the upper thread becomes tangled in the bobbin case, causing a rattling noise.
Remedy / Check details
Remove the tangled thread, and then correct the upper threading.
Turn off the sewing machine.
Remove the tangled thread. If it cannot be removed, cut the thread with scissors.
If the threads remain in the bobbin case, remove the needle plate cover, and then remove the threads.
If the bobbin was removed from the bobbin case, install the bobbin in the bobbin case correctly.
Refer to How do I set the bobbin.
Remove the upper thread from the machine.
Turn on the sewing machine.
Raise the presser foot using the presser foot lever.
If the presser foot is not raised, the machine cannot be threaded correctly.
Raise the needle by turning the handwheel toward you (counterclockwise) so that the mark on the wheel points up, or press Needle Position button once or twice to raise the needle.
While holding the thread with both hands, pull the thread up from under the thread guide plate.

While holding the thread in your right hand, pass the thread through the thread guide in the direction indicated.
Guide the thread down, up, then down through the groove, as shown in the illustration.
Look in the upper groove area to check if the thread catches on the thread take-up lever visible inside the upper groove area.

Pull the thread up through the thread cutter to cut the thread, as shown in the illustration.
(1) Thread cutter
- When using thread that quickly winds off the spool, such as metallic thread, it may be difficult to thread the needle if the thread is cut.
Therefore, instead of using the thread cutter, pull out about 80 mm (approx. 3 inches) of thread after passing it through the thread guide disks (marked 7).
80 mm (approx. 3 inches) or more
Press the Automatic Threading button to have the machine automatically thread the needle.
>> The thread passes through the eye of the needle.
When the Automatic Threading button is pressed, the presser foot will be automatically lowered. After threading is finished, the presser foot moves back to the position before the Automatic Threading button was pressed.
Carefully pull the end of the thread that was passed through the eye of the needle.
If a loop was formed in the thread passed through the eye of the needle, carefully pull on the loop of thread through to the back of the needle.
Pulling the loop of thread gently will avoid needle breakage.
Pull out about 100-150 mm (approx. 4-6 inches) of the thread, and then pass it under the presser foot toward the rear of the machine.

Some needles cannot be threaded with the needle threader. In this case, instead of using the needle threader after passing the thread through the needle bar thread guide (marked 6), manually pass the thread through the eye of the needle from the front.
Press the Presser Foot Lifter button to raise the presser foot.
