Bring the machine to needle rise position by turning the handwheel.
Manually activate engaging lever 1 so that pawl 2 engages.
Taking care to ensure that screw 3 is still loose, press control lever 4 down to the base

Maintaining this position, lightly tighten screw 3 while bringing release trip 6 into a
resting position against engaging lever 1 and laterally against control lever 2 in the

tapping control lever 4, create a distance between the bolt and the base of the cam track
