Turn the machine pulley 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 adjust the two set screws (4) of the
rotary hook joint (3) so that the rotary hook tip (2) 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).
NOTE:
When installing the rotary hook joint, install using the set
screws so that the oil inlet [A] in the rotary hook (5) is
aligned with the oil inlet [B] in the rotary hook joint
assembly (6).
10-6. Adjusting the needle guard
Turn the machine pulley to align the tip of the rotary hook (1) with the center of the needle, and then loosen the bolt (3) and
turn the needle guard adjusting shaft (4) to adjust so that the needle guard (2) is touching the needle.
NOTE:
If it 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 (1) will interfere with the needle and skipped
stitches may occur.
