Upper thread tightened up
Symptom
|
(1) Lower side of fabric (2) Lower thread visible from upper side of fabric (3) Upper thread (4) Upper side of fabric (5) Lower thread |
Cause
If the lower thread is incorrectly threaded, instead of the appropriate tension being applied to the lower thread, it is pulled through the fabric when the upper thread is pulled up. For this reason, the thread is visible from the upper side of the fabric.
Remedy/check details
Correctly install the lower thread according to the following procedure.
|
(1) Cover (2) Slide button |
Put the bobbin in so the thread comes out in the direction shown by the arrow.
Make sure you set the bobbin so the thread unrolls in the right direction. If the thread unrolls in the wrong direction, it may cause the thread tension to be incorrect or break the needle.
Hold the end of the thread, push the bobbin down with your finger, and then pass the thread through the slit, as shown.

(1) Tension-adjusting spring |
Replace the cover so that the end of the thread comes out from the left side of the cover (as shown by the line in the diagram).
