Adjustment Procedures
1) Loosen the setscrew in the feed bar guide B.
Refer to "(33) Adjusting the feed bar guides A and B".
2) Remove the top cover and loosen setscrew 1 in the top feed
arm C.
Refer to (30) Adjusting the longitudinal position of the top feed
dog.
3) Loosen the setscrews in thrust collars 2 located on the both
sides of the horizontal shaft and move the set of horizontal
shaft, top feed bar and top feed dog to the predetermined
position in the thrust direction (direction you desire to adjust
the position). Then fix two thrust collars 2 at the position.
(Reference) When loosening the setscrews in thrust collars
2, do not simultaneously loosen the two setscrews. First,
loosen thrust collar 2 on the side of moving direction and
fix it at the predetermined position. In the state of pressing
it in the direction, check that contact at the lateral position
or at the top feed mechanism does not occur. After the
checking, move and fix the remaining thrust collar 2. The
aforementioned procedure can perform good adjustment.
4) Tighten the respective setscrews by reversing the
aforementioned order and perform the adjustment.
