To Regulate the Stitch Length
Most sewing will be done with
the maximum stitch length. How-
ever, the length of the stitch can be
adjusted as follows:
(1) Loosen the thumb nut on the
stitch length lever.
(2) Raise the stitch length (feed
regulator) lever until the desired
stitch length is obtained.
(3) Tighten the thumb nut.
See fi g. 6.
Reverse Sewing
To sew in reverse
1 Lower the feed regulator (stitch length) lever all the way
to the bottom of the slot in the stitch length plate.
2 Hold the lever there until reverse sewing is completed.
3 Then return the lever to the forward position.
Straight Sewing and ZigZag Sewing
For straight sewing, set the zigzag width control lever
at “0”. For zigzag sewing, make sure the presser foot is
for zigzag use. Zigzag stitch is
controlled by the zigzag width
control lever on the front of this
machine. By moving this control
lever gradually to the left toward
“5”, the machine will sew a zigzag
seam of increasing width depend-
ing on the position of the control
lever.
