Changing the programmed roller presser
feed motion
In order to avoid inputting a new sewing program
when using different material with the same pro-
gram it is possible to increase or decrease the roller
presser feed motion by steps of 1/10 mm.
In the display the seam segment indication is
followed by the selected difference. With an
increase of 0.3 mm e.g.:
10 R1 +0.3 50 _._ 2.5
With a decrease of the roller presser feed motion
the difference is preceded by a minus sign.
There are two options:
1.Increase or decrease the roller presser feed
motion for all seam segments of a program.
To this end press keys or on the
control panel before sewing is started with the
control being at the start of the selected
program.
2. Increase or decrease the roller presser feed
motion for individual seam segments of a
program.
As soon as the control is at the desired seam
segment, press keys or on the
machine head .
After incrementing to the following seam
segment the selected increase or decrease of
the roller presser feed motion will no longer be
valid.
Note:
If keys or are pressed when “Manual”
is selected (program number 0), the roller presser
feed motion is changed immediately and the new
feed motion is displayed.
Size selection
Note:
Size selection is possible only
- with program numbers 3 to 24 when “sewing”
mode is selected
- if seam segment are incremented by means of
lenght measurement and grading is used (knee
switch disabled)
- if the control is at the start of the sewing
program and the sewing procedure has not
been started yet.

another size with the numeric keys.
