7. PRESSURE REGULATING DIAL
This dial regulates the pressure that the presser foot
exerts on the fabric. Correct pressure is important
because it means fabric feeds smoothly, evenly, without
being marred. Generally, heavy fabric requires a high
number setting; lightweight fabric requires a low num­
ber setting.
• To increase pressure, turn dial to higher number.
• To decrease pressure, turn dial to lower number.
• For darning, turn dial to D, vvhich releases pres­
sure and permits darning without an embroidery
hoop.
