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 genuine parts approved by the company only.
Warning

6.1) Adjusting the Height of the Needle Bar

When the needle bar is at its lowest position, unfasten the
needle bar holder screw. 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 back on firmly.

6.2) Adjusting the Needle and the Shuttle

1) 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.
2) Adjusting the shuttle timing(1507-ES)
3) After unfastening the shuttle drive screw, open the inner hook pressure bar left to right and remove the shuttle
Race ring from the (large) shuttle.
4) Make the shuttle hook point Ⓐ accord with the center of the needle. And make the needle and the front face of
the shuttle drive Ⓑ connect each other to prevent the needle from curving. Then, tighten the drive screw firmly.
5) After unfastening the (large) shuttle screw, turn the large hook adjustment shaft to the left to right and adjust the
(large) shuttle so that the needle and the shuttle hook point Ⓐ is 0.05~0.1mm apart from each other.
6) After adjusting the (large) shuttle in place, adjust the rotary direction of the (large) shuttle so the needle and the
(large) shuttle is 7.5mm apart from each other. Then, tighten the (large) shuttle screw.
For safety, make sure all the screws are tightened firmly after adjusting the (large) shuttle.
