The presser foot must be lowered prior to adjustments.
Smooth, even hdj:\Qling of several thicknesses of fabric
results when pressure is correctly regulated. Heavy pres-
sure is for thick fabric and light pressure is for thin fabric.
Too light a pressure will result in irregular feeding which
affects both quality of stitch and evenness of seams.
Too heavy a pressure not only affects stitch and seam
quality but will also mar smooth surfaces and pile fabrics.
Surface finish, as well as the weight and texture of the
fabric, must be considered in determining the amount of
oressure needed.
