For larger sewing material thickening, sometimes the stitch depth of a stitch
should be reduced over a shorter or longer section. By adjusting the scale on
the right of the stand, the plunger can be lowered from 0 to up to 3.8 mm by
pushing a button. To do so, the thread tension is increased by an additional
thread tension.
Setting the plunger lowering
To set the plunger lowering, cover (3) and the lower-arm cover must be
removed and the needle tip must be moved to the centre of the plunger using
the handwheel.
Set eccentric bolt (1) to approx. 45° and fix with threaded screw (2) in the
bearing. (Fig. 10)
Fig. 10
Set the plunger to the highest possible point and adjust the eccentric (1) to
approx. 15° at the stop of scale (2) at pin (3). Fix the scale in this position on
the eccentric. (Fig. 11)
