FAQs & Troubleshooting |
Upper thread tightened up
Symptom
|
(1) Wrong side of fabric (2) Bobbin thread visible from right side of fabric (3) Upper thread (4) Right side of fabric (5) Lower thread |
Cause
Incorrect bobbin threading
If the bobbin thread is incorrectly threaded, instead of the appropriate tension being applied to the bobbin thread, it is pulled through the fabric when the upper thread is pulled up. For this reason, the thread is visible from the right side of the fabric.
Remedy/check details
Correctly install the bobbin thread.
If the message OK to automatically lower the presser foot? appears on the LCD screen, press [OK] to continue.

(1) Tab |
Be sure to hold down the bobbin with your finger and unwind the bobbin thread correctly, otherwise the thread may break or the thread tension will be incorrect.
By guiding the thread around the tab of the needle plate cover, passing the thread as shown by B in this illustration, then lightly pulling the thread at C, the thread will enter the tension spring of the bobbin case to apply the appropriate tension to the bobbin thread during sewing.
Be sure to complete the bobbin threading correctly according to these instructions. If the thread is simply placed in the slit in the needle plate cover, the bobbin thread will not be correctly threaded, resulting in poor sewing performance or incorrect thread tension.
