    내에서  조정해주십시오.

1.  When  the  feed  dog  ①  is  fully  raised,  its  angle  is  properly  adjusted  if  the  circle  on  the  feed  bracket 

      shaft  ④  aligns          with  the  index  on  the  feed  rock  shaft  arm  ⑤.

2.  To  adjust  the  feed  dog  ①  angle,  loosen  the  two  screws  ⑥  and  then  rotate  the  feed  bracket  shaft
