A T T E N T I O N !
Switch off machine electrically and make sure that it is
really in standstill position by healing the tradle for the
motor control before setting the stitch length. Otherwise

As shown in Fig. 7, the stitch length can be adjusted by means of stitch
adjusting knob 344.0089 in the inside of the left handwheel, which is equipped
with pointer 124.0080 showing through the “S” slot in the handwheel.
The handwheel has a scale according to which pointer 124.0080 has to be set.
The figures of this scale do not represent a certain stitch length in mm, but
serve as reference figures only. However, low figures mean smaller stitch
length and viceversa.
