Catch bartack
To ensure a safe sewing start and complete
sewing of the start bartack, an additional
bartack can precede the start bartack.
Only the number of forward and backward
stitches can be selected. The stitch length
cannot be set individually – it corresponds
to the stitch length of the normal start

depending on the number of sections.

direction of the bartack.
