The pressure of the presser foot can be adjusted by turning the pressure adjustment screw at the top left of this machine. Since this machine has already been adjusted to a pressure suitable for light to medium fabrics, no further adjustment is necessary except when sewing on very heavy or very light materials.
Usually, when sewing on very light materials, the presser foot pressure should be loosened. When sewing very heavy materials, the presser foot pressure should be tightened.
