4. Place the brand new bobbin into the bobbin case. Make sure that the thread is unwinding from the bobbin in a counterclockwise route.
5. Insert the bobbin case again into its compartment, aligning it with the suitable slots or guides.
6. Push the bobbin case again into place till it clicks or snaps securely.

Thread Path Administration

1. Find the thread information on the highest of the bobbin case.
2. Thread the surplus thread tail by way of the thread information, guaranteeing it follows the designated path.
3. Gently pull the thread till it’s taut, however not overly tight.
