The amount of pressure influences the
ease with which you achieve a straight
seam and uniform stitching. The pres-
sure should be heavy enough to prevent
side creepage of material and light
enough to carry the material without
marking.
To set a light pressure, turn thumb
screw U, Fig. 22 upward until fabric
moves easily under presser foot without
slipping and without showing feed
marks.
To set a heavy pressure, turn thumb
screw U downward until the fabric
moves easily and the seam edges are car-
tied evenly by the foot and the feed.
