Your machine is equipped with 2 feed dogs, (b) and
{c), each of which moves independently. However,
when the differential feed control slide {a) is set
at 1.0, both feed dogs move together at the same
ratio.
@ By sliding the differential feed control slide (a)
down to a higher number, the front feed dog {b)
moves the fabric faster, as shown.
This helps to
prevent materials such as knitted or stretch fabrics
from waving during sewing.

By sliding the differential feed control slide (a) up
to a lower number, the front feed dog (b) moves
the fabric more slowly, as shown.
This helps to
prevent sheer and light-weight fabrics from pucker-

Before starting to sew, make a test on a scrap of
your fabric.
