- Guide the thread through the first thread guide.

3. Installing the Bobbin
The machine uses metal bobbins. To install or replace a bobbin:
- Slide open the bobbin cover plate located on the sewing bed.
- Insert a wound bobbin into the bobbin case, ensuring the thread unwinds in the correct direction (usually counter-clockwise).
- Pull the bobbin thread through the small slot in the bobbin case.
- Close the bobbin cover plate.
- Turn the hand wheel to lower the needle, catching the bobbin thread, and pull both threads to the back.

The tension dial controls the tightness of the upper thread. Adjust as needed for different fabric types to achieve balanced stitches. Turn clockwise for tighter tension, counter-clockwise for looser tension.
