15. ADJUSTING THE FORWARD REVERSE STITCH
When stretch stitch sewing, the lengths of the for-
ward and reverse stitches should be the same.
Check and adjust as follows.
• We recommend checking "Height of the Feed-dog
(Sec. 4)" before you make this adjustment.
Check
1. According to service program menu 4, select the
mending stitch No. 1(See page 26).
2. Attach the satin stitch foot B and sew a mending
stitch. (Machine will repeat sewing forward and
backward and stop automatically.)
3. Difference of both ends of right and left should be
0~3mm.
If they are not so, adjust as follows.
Adjustment
1. Tilt the machine backward.
2. The forward-reverse stitch length is adjusted by
turning the screw (c).
• If the reverse stitch is coarser than the forward
stitch, turn the screw to the right (+).
• If the reverse stitch is finer than the forward stitch,
turn the screw to the left (-).
