Setting the stitch condensing
NOTICE
Property damage may occur!
Machine damage possible if the adjusting wheels are turned
using excessive force.
The machine is designed in such a way that it is not
possible to select a larger stitch length on the lower
adjusting wheel than on the upper adjusting wheel.
DO NOT attempt to set a longer stitch length on the lower
stitch length adjusting wheel wheel than on the upper stitch
length adjusting wheel.
For machines with pushbuttons on the machine arm ( p. 52) it
is possible to switch over to stitch condensing while sewing. The
stitch length for stitch condensing can be adjusted by turning the
adjusting wheel continuously between 1 and 4 mm.
