Sewing on Heavy Fabrics
The black button on presser foot "A" locks the foot
in a horizontal position when pushed in before
lowering the presser foot. This ensures even
feeding at the beginning of seams and helps when
sewing many layers of fabric such as welt seams
used to hem jeans.
When the point of an increased thickness is
reached, lower the needle and raise the presser
foot. Press in the black button q. Lower the foot and
continue sewing.
This button releases automatically after a few
stitches have been sewn.
NOTE: Increase stitch length between 3.0 and 4.0
for heavier fabrics.
