Fig. 16: Adjusting the thrust movement of the feed dog (1)
Proper setting
To ensure proper stitch formation, the feed dog completes a slight subse-
quent advance after the needle bar has reached the top dead center.
To adjust the thrust movement of the feed dog:
1. Loosen the screws of the pusher eccentric (3).
2. Lock the machine in place in slot D ( p. 13).
3. Insert the gage (2) into the slot (1) of the pusher eccentric (3).
4. Turn the pusher eccentric (3) such that the edges of the gage (2) rest
on the stitch regulator linkage (4).
CAUTION
Risk of injury from moving parts!
Crushing possible.
Switch off the machine before adjusting the feed
dog.
