- Guide the thread through the bobbin winder tension disk.
- Wind the thread clockwise around the empty bobbin a few times.
- Push the bobbin winder pin to the right.
- Turn on the machine (ensure the needle is not threaded). The bobbin will start winding.
- Once the bobbin is full, turn off the machine, cut the thread, and push the bobbin winder pin back to the left.
3.3 Threading the Machine (Upper Thread)
Follow the numbered threading indications printed on the machine body for easy guidance.

- Ensure the machine is turned OFF.
- Raise the presser foot lifter.
- Turn the hand wheel towards you to raise the needle to its highest position.
- Place a spool of thread onto the spool pin.

3.4 Inserting the Bobbin (Lower Thread)
- Open the bobbin cover plate.
- Insert the wound bobbin into the bobbin case, ensuring the thread unwinds in the correct direction (usually counter-clockwise).
- Guide the bobbin thread through the tension spring slot.
