The sewing machine can be fitted with various shaping modules for
different seam patterns.
See section 2.12 of the Operating manual.
Regulation and inspection

play.
The material clamps must be fitted so that the adjusting pins
(gauge 1, section 2.1) can be inserted through holes 4.
The pressure of the folding rims (pre-tension of the material clamps) is
determined by the curvature of the shaping module.

Turn off the main switch.
Remove the shaping module from the sewing machine and adjust it.
