1.3 Threading the Machine

Proper threading is crucial for consistent stitch quality.

1. Upper Threading: Follow the numbered guides on the machine for correct upper thread path. Ensure the thread is seated firmly in the tension discs.
2. Bobbin Winding: Place an empty bobbin on the bobbin winder spindle. Follow the winding path indicated on the machine. Engage the winder and press the foot control or start button until the bobbin is full.
3. Bobbin Insertion: Open the bobbin cover plate. Insert the wound bobbin into the bobbin case, ensuring the thread unwinds in the correct direction (usually counter-clockwise). Pull the thread through the tension spring and out the slot.
