The standard position of arm thread guide R (1) is when the

screw (2) is aligned with the index mark.

Loosen the screw (2) and move arm thread guide R (1) to

adjust.

* When sewing heavy material, move arm thread guide R

(1) to the left. (The thread take-up amount will become

greater.)

* When sewing light material, move arm thread guide R

(1) to the right. (The thread take-up amount will become

less.)

11-3. 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 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).

11-4. Adjusting the needle bar lift amount

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 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.
