HOW TO REPAIR THE MACHINE
The machine is set to be the best condition at the factory. Do not make any discrete adjustments
on the machine and replace accessories approved by the company only.

When the needle bar is at its lowest position,
unfasten the needle bar holder screw ①. Adjust the
desired height by making the specified upper
carving line fit in with the needle bar bushing.
Then, tighten the needle bar holder screw ① back
on firmly.
2) Adjusting the needle and the shuttle
B. After unfastening the shuttle drive screw ①, open the inner hook pressure bar ② left to right and remove the
shuttle lace ring ③ from the (large) shuttle ④.
C. Make the shuttle hook point accord with the center of the needle. And make the needle and the front
facet of the shuttle drive connect each other to prevent the needle from curving. Then, tighten the drive
screw ① firmly.
D. After unfastening the (large) shuttle screw ⑤, turn the large hook adjustment shaft ⑥ to the left to right
and adjust the (large) shuttle ④ so that the needle and the shuttle hook point is 0.05~0.1mm apart from
each other.
E. After adjusting the (large) shuttle ④ in place, adjust the rotary direction of the (large) shuttle ④ so the
needle and the (large) shuttle ④ is 7.5mm apart from each other. Then, tighten the (large) shuttle screw ①.
A. Have the lower carving line for the needle that
is applied when the needle bar goes up fit in
with the lower side of the needle bar bushing as
shown in the picture.
