Setting the stitch length
Turn the stitch length setting knob in such a
way that the desired stitch length is indica-
ted at the setting mark. The higher the num-
ber, the longer the stitch. The stitch length
can be adjusted between 1 and 5 mm.
The setting R is used for sewing rolled hems.
Setting:
– Turn the setting knob counterclockwise
(towards 2.0) to achieve gathering effects
on lightweight fabric or to smooth fabric
that is being overly stretched out of
shape.
– Turn the setting knob clockwise (towards
0.7) to achieve a ruffled (lettuce) effect on
knit or bias-cut fabrics or to smooth fabric
that is being contracted while sewing.
Setting the differential feed ratio
The differential feed ratio can be altered by
turning the setting knob. The number at the
setting mark shows the ratio between the
two feed dogs arranged behind each other.
The normal setting is 1.0.
The maximum differential feed ratio (2.0) is
only fully effective within the setting range
from 1 to 3.3 on the stitch length setting
knob. If the stitch length setting knob is set
to a value between 3.3 and 5.0, the differen-
tial feed ratio is automatically adjusted to a
value between 2.0 and 1.3.
