10-4. Adjusting the needle bar height 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Turn the pulley in the direction of the arrow to move the needle bar to the lowest position. Then remove the rubber plug (2), 
loosen the screw (3) and then move the needle bar up or down to adjust so that the second reference line from the bottom 
of the needle bar (reference line A) is aligned with the lower edge of the needle bar bush (1). 
*  If using a DP X 5 needle, use the highest reference line (reference line a). 
10-5. Adjusting the needle bar lift amount 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Turn the pulley in the direction of the arrow to raise the needle bar from the lowest position until the lowest reference line on 
the needle bar (reference line B) is aligned with the lower edge of the needle bar bush (1), and then loosen the bolt (2) and 
move the driver (3) so that the tip of the rotary hook is aligned with the center of the needle. 
*  If using a DP X 5 needle, use the second reference line from the top of the needle bar (reference line b). 
10-6. Adjusting the needle contact pressure of the driver 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
 
Turn the pulley in the direction of the arrow to align the tip of the rotary hook with the center of the needle, and then loosen 
the set screw (2) and turn the eccentric shaft (3) to adjust so that the driver (1) is touching the needle. 
NOTE: 
If the driver (1) crosses the needle more than necessary, it will place a load on the needle, or it may cause poor thread 
tension. Furthermore, if it does not cross the needle at all, the tip of the rotary hook will interfere with the needle and 
skipped stitches may occur.
