How do I correctly install a bobbin?
- Make sure bobbin thread unrolls in the correct direction when installing the bobbin into bobbin case.
- Be sure to set a bobbin so that thread unrolls in the correct direction.
If the thread unrolls in the wrong direction, the needle may break or the thread tension will be incorrect.
- Use a bobbin that has been correctly wound with thread.
Otherwise, the needle may break or the thread tension will be incorrect.Wound evenly Wound poorly
- Be sure to set a bobbin so that thread unrolls in the correct direction.
- Be sure to insert the thread through the tension-adjusting spring of the bobbin case.
In step 3 and 4 below, a hint for inserting thread through tension-adjusting spring and how to check if it's properly inserted will be described.Tension-adjusting spring

- In case of a machine equipped with Quick-set bobbin (needle plate with a cutter for bobbin thread), lightly hold down a bobbin with your finger and cut the thread with the cutter when installing a bobbin into a bobbin case so that the thread can be inserted through the tension-adjusting spring surely.
Cutter
You will feel some resistance when pulling the thread toward the blue arrow direction, if the thread is surely inserted through the tension-adjusting spring.
However, you will be able to pull the thread easily without any resistance or friction, if thread is not inserted through the tension-adjusting spring. - If thread is inserted through the tension-adjusting spring surely, the bobbin thread passes over the bobbin when it is pulled up, as shown in the below illustration.
