To start or to continue the winding process, simply press the START button; To stop or to pause winding, press the STOP button. The automatic bobbin winder will stop on its own once the thread is full. Use the thread cutter on the side to cut your thread.
This is the tension adjustment disc. You can adjust the thread tension by rotating the tension knob clockwise or counterclockwise.
If your bobbin doesn’t fit, try adjust the position of the black sensors by using a screwdriver. The edge of the bobbin should be in line with the middle point of the sensors.
