In automatic reverse stitching, in case the forward and the reverse stitches do not match, a rough correction
can be made by adjusting the feed adjustment spring hook 1 .
* To make a fine correction, the correction of timing of the reverse feed stitching solenoid is nec-
essary by adjusting Function Setting Nos. 51, 52 and 53. Refer to the Instruction Manual for the
control box (SC-920) for details of adjustment procedure.
1) In case the stitch does not match the target as shown in 3 , loosen feed adjustment spring hook fixing
screw 2 , make 1 slide in A direction, and fix using the screws 2 .
2) In case the stitch does not match the target as shown in 4 , loosen feed adjustment spring hook fixing

It is possible to change the stitch length of the nor­
mal feed pitch by operating switch 1 or reverse feed
control lever 2 during sewing.
1) Tilt the machine head, and loosen three fixing
screws 4 of the reverse feed solenoid 3 .
2) Slide reverse feed solenoid 3 in the direction of
the arrow to adjust so that the center of screw
4 is aligned with engraved marker line 5 repre­
senting the condensation stitch length. Then fix
the solenoid with setscrews 4 .
3) To return the stitch length back to the initial set­
ting (to reset), slide reverse feed solenoid 3 n
the direction of arrow A until it comes in contact
with the end face of slit in bed strut B 6 . Then,
fix the solenoid at that position with setscrews 4 .
