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.
