3. To delay the f eed timing in order to increase stitch tightness, move the Feed Eccentric
Cam down (counterclockwise).
Adjusting the Height of the Feed Dog
The Feed Dog is factory adjusted so that it juts
out from the Throat Plate surface 0.8 mm to 0.9
mm. If the Feed Dog juts out too much, pucker-
ing may result when sewing lightweight materi-
als. To adjust the height of the Feed Dog:
1. Loosen Screw (2) of Crank (1).
2. Move the Feed Bar up or down to make
the adjustment.
3. Tighten Screw (2), being careful not to
overtighten.
Adjusting Needle-to-hook Timing
1. Turn the Hand Wheel to bring the needle
bar down to the lowest point of its stroke.
2. Loosen Set Screw (1).
3. When using a DBX1 needle, align to
marker line “A” on the needle bar (2) with
the bottom end of the needle bar lower
bushing (3), then tighten Set Screw (1).
When using a DAX1 needle, align to
marker line “B” on the needle bar (2) with
the bottom end of the needle bar lower
bushing (3), then tighten Set Screw (1).
4. When using a DBX1 needle, loosen three
Hook Set Screws, turn the Hand Wheel,
and align the marker line “B” on the needle
bar (2) with the bottom end of the needle
bar lower bushing (3).
When using a DAX1 needle, align the marker line “D” on the needle bar (2) with the
bottom end of the needle bar lower bushing (3).
5. After making the adjustments in steps 3 and 4, align the Hook Blade point (5) with the
center of the needle (4).
Provide a clearance of .001” to .004” (0.04 to 0.1 mm) between the needle and the
hook. This clearance is less than 1/64” (almost touching). Securely tighten the three
Set Screws. If the clearance is too small, the tip of the hook will be abraded. If it is too
large, it will lead to skip over.
