Adjusting the needle bar height:
Turn the machine pulley 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 of 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).
Adjusting the needle bar lifting amount:
Turn the machine pulley to rise 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 screw (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 top of the needle bad (reference line b).
When installing the rotary joint, install using the set screw so that the coil inlet [A] in the rotary hook (5) is aligned with the coil inlet [B] in the rotary joint assembly (6)
