Your Baby Lock serger is equipped with differential feed.The set of feed
dogs work independently in order to ensure smooth sewing on all
fabrics.
When the differential feed adjusting lever, located at the machine's right,
front edge is set on "N" for normal feeding, the feed dogs move the same
distance. This is the setting to use for most fabrics and applications.
When the dial is set above "N" (fig.B), the front feed dog will feed more fab-
rics than the back. This is because the front feed dog moves at a greater
distance than the back feed dogs. As a result, the fabric becomes com-
pressed or eased, as the diagram on the front cover indicates. This can
eliminate wavy seams in stretchy fabrics or those cut on the bias grain
(fig.A).
At the maximum setting of 2.0 (fig. C), the differential feed can gather a
lightweight fabric to nearly double fullness (fig. D).
The front feed dog is actually feeding in twice as much fabric as the back
feed dog is feeding out. To maximize the gathering effects, use the longest
stitch length setting. Fabric weight will affect the gathering. Test stitch for
desired results.
When the differential feed lever is set below "N" (fig. F), the front feed dog
moves less distance than the back feed dog. This adjustment stretches the
fabric slightly as it is sewn. The lower settings prevent puckers on lightweight
fabric (fig. E), add more stretch to swim wear, active wear, and can be used
to create a lettuce edge (page 33).
