7.4 Setting the eccentric for the forward and backward
stitches
Correct setting
The forward and backward stitches are the same length.
As a test, sew a seam forwards, stop, and sew a seam backwards.
The insertions of the forward and backward stitches have to lie within
each other.

Setting steps
1. Loosen the setscrew (3).
2. Turn the eccentric screw (1) from the right through the opening in the
base plate:
Basic position:
The slot in the eccentric screw (1) is parallel to the machine axis, the
recess (2) faces the front.
If the forward and backward stitches are not the same length:
• Turning clockwise:
The forward stitch becomes larger, the backward stitch smaller.
• Turning anticlockwise:
The forward stitch becomes smaller, the backward stitch larger.
3. Tighten the setscrew (3).
