3. Setup

3.1 Power Connection

Connect the foot controller plug into the machine's power input. Ensure the machine is placed on a stable, flat surface before connecting to a power outlet. The machine operates on 120V, 60Hz (84 Watts).

3.3 Winding the Bobbin

Place an empty bobbin onto the bobbin winding spindle. Guide the thread from the spool through the bobbin winding tension disc and around the bobbin. Push the spindle to the right to engage the winding mechanism, then gently press the foot controller to wind the thread evenly onto the bobbin. Once full, push the spindle back to the left and trim the thread.
