Rule
There should be a clearance of approx. 0.3 mm between the tripping lever bolt and the
bottom of the cam track in the needle rise position and when the engaging lever 4 is
dropped in place.
O Move the machine to the needle rise position.
O Activate the engaging lever 1 by hand so that the pawl 2 drops into place.
O Press the tripping lever 4 to the bottom of the control cam 5, ensuring that the screw 3 is
still loosened.
O While maintaining this position, move the release cam 6 in the direction of the arrow so
that it touches the engaging lever 1 and the side of the tripping lever 4 and then gently
tighten the screw 3.
O Create a clearance between the bolt and the bottom of the cam track according to the
rule by gently knocking on the release cam 6 in the direction of the arrow and tapping on
the tripping lever 4 at the same time.
