The presser foot pressure of the machine has been pre-set and
requires no particular readjustment according to the type of
fabric (light-or-heavy weight).
However, if you need to adjust the presser foot pressure, turn
the presser adjusting screw with a coin.
For sewing very thin fabric, loosen the pressure by turning the
screw counter-clockwise, and for heavy fabric, tighten by
turning it clockwise.
To return to initial pressure foot setting turn the pressure
adjusting screw to become flush with the face cover.
