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.
