2. Winding the Bobbin

Before you begin sewing, the bobbin needs to be wound with thread.

1. Place a spool of thread on the spool pin.
2. Guide the thread through the thread guide.
3. Place an empty bobbin onto the bobbin winder spindle.
4. Wrap the thread around the bobbin a few times manually.
5. Push the bobbin winder spindle to the right.
6. Turn on the machine to the 'L' (Low) speed setting. The bobbin will start winding.
7. Once the bobbin is full, turn off the machine, cut the thread, and push the bobbin winder spindle back to the left.

3. Threading the Machine (Upper Thread)

Proper threading is crucial for correct stitch formation.

1. Raise the presser foot lifter.
2. Place the thread spool on the spool pin.
3. Guide the thread through the first thread guide (1).
4. Pass the thread through the tension disc (2).
5. Thread the take-up lever (3) from right to left.
6. Guide the thread down through the needle bar thread guide (4).
7. Thread the needle from front to back. Use the needle threader if available.
8. Pull about 4 inches of thread through the needle eye and place it under the presser foot.

4. Installing the Bobbin (Lower Thread)

1. Open the bobbin cover plate.
2. Insert the wound bobbin into the bobbin case, ensuring the thread unwinds counter-clockwise.
3. Guide the bobbin thread through the tension spring.
4. Turn the handwheel counter-clockwise to lower and then raise the needle. This will bring the bobbin thread up through the needle plate.
5. Pull both upper and lower threads to the back, under the presser foot.
6. Close the bobbin cover plate.

5. Changing Needle and Presser Foot

To change the needle:

1. Loosen the needle clamp screw.
2. Remove the old needle.
3. Insert the new needle with the flat side facing the back of the machine. Push it up as far as it will go.
4. Tighten the needle clamp screw securely.

To change the presser foot:

1. Raise the presser foot lifter.
2. Press the release lever at the back of the presser foot holder to detach the current presser foot.
3. Align the new presser foot with the holder and lower the presser foot lifter until it snaps into place.

Operation
