ADJUSTING PRESSER FOOT PRESSURE
The presser foot pressure of the machine
has been pre-set and requires no
adjustments for most fabric weights.
However, if you choose to adjust the
presser foot pressure, turn the presser
adjusting screw with a coin.
For sewing very heavy fabric, loosen the
pressure by turning the screw counter
clockwise, and for thin fabric, tighten by
turning it clockwise.
