Normally is a loop stroke of 2.8 mm. If it is necessary to change the loop stroke,
then slacken the two screws in the toothed wheel, (1) at the rear of the head
(Fig. 3). By turning this toothed wheel, the shuttle can be set so that it takes
hold of the thread loop earlier or later. When tightening the two screws, check
for normal play between the bevel wheels. If the loop stroke is altered, then the
needle lever almost always has to be readjusted.
