1. Find the thread clamp adjustment knob on the sewing machine and turn it clockwise to the tightest position.
2. Use the thread clamp to touch soft fabrics such as towels, and adjust the adjustment knob so that the thread clamp can clamp the fabric slightly, but not too tightly.
3. After the adjustment is completed, use a sewing machine to sew a section of thread and observe whether the clamping degree of the thread clamp is appropriate. If the clamping force is too large, turn the adjustment knob counterclockwise; otherwise, turn the knob clockwise to increase the clamping force.
