The stitch length adjusting dial is con-
veniently  located just to the left of the
front cover, near the base plate (fig. A).
The  dial  shows  the  stitch-length  rang-
ing from 1, for the shortest stitch, to 4
for the longest.
Simply  turn  the  dial  aligning  the
desired setting with the indicator mark

on the machine.  A stitch length of 3mm, or about 10 stitches per inch is ideal for most fabrics.
For seaming very lightweight fabrics, you may prefer a shorter stitch length. When sewing heav-
ier fabrics, you may choose to lengthen the stitch (fig. B).

Differential Feed

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 (fig. A)

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 (fig. B).

When the dial is set above "N", 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  compressed  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.

At the maximum setting of 2.0 (fig. C),  the differential feed can gath-
er 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 gather-
ing.  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).
