OTHER ADJUSTMENTS OF MACHINE IN SEWING
In addition to the obvious controls of your machine there are other small regulators and controls to aid you in using your sewing machine.
PRESSER FOOT PRESSURE REGULATOR
Push down outer ring of presser foot pressure regulator (See above illustration). This will release pressure of presser foot. To increase pressure, push down inner pin until suitable pressure is obtained. For ordinary sewing, the inner pin should be all the way down.
Insufficient pressure may cause poor feeding of the fabric, skipped stitches, or difficulty in guiding the fabric.
When sewing multiple thickness or heavy fabric reduce the pressure. Increase pressure when sewing lighter weight fabrics. If feed dog or presser foot marks appear on the fabric, reduce the pressure.
