Screw the control knob (1) onto the shaft or the adjustment bolt (2) until the
control knob contacts the handwheel. Hold the control knob tight and screw out
the adjustment bolt until the pointer (3) on the control knob of the handwheel
(marking 5), (large stitch), contacts and can be slightly seen between
handwheel and stand. (Fig. 7)
The control knob needs to be free from the large to the small stitch.
If the setting has been done properly, the variable eccentric (1) is standing at
the large stitch at the top dead centre and the pointer of the control nut is at the
marking 5 on the handwheel. To complete, the counter nut (5) is screwed on.

Fig. 4), the ecc. pin (B)
(1) needs to be set to the determined position for the stitch length specified for
each class (see "2.5 Abridged version of adjustment manual"). Please be sure
that the rocker (2) and the connecting rod (3) are not stretched out. The
marking (punch mark) made on the ecc. pin (1) (Fig. 6) has to be mounted
upwards in any case. This has the effect that the punch mark is swivelled to the
right (-) for a smaller stitch and to the left (+) for a larger stitch - arrow direction.
