4-4. Quick reverse mechanism
1. When the actuator is pressed lightly, the movement is transmitted to the various parts as shown in the illustration, so
that the angle of the feed regulator assembly is reversed.
2. When the angle of the feed regulator assembly is reversed, the feed rocker arm link and feed rocker arm change from
normal feed to reverse feed.
* Operation occurs in the same way as described above even when the reverse stitching lever (1) is lowered.
