              Check\uff1a The space between the right looper and needle is too wide?
              Adjustment\uff1a When the right looper turn right and backward, the distance to the needle has to be 0.1 mm, which is using the correct right looper. (The appropriate right looper for each type, such as single need, 2 needles, materials, and thin fabrics, are included)
              Check\uff1a The distance is too wide between the right and left needle when using 2 needles?
              Adjustment\uff1a Because the correlationship of the left\/right position of the right looper while assembling and the up\/down moving position of the right looper seat, adjust the movement path of the looper. When the right looper descends, decrease the descending amount from left needle to right needle.<\/p>\t\t\t\t\t\t<\/div>\n\t\t\t\t<\/div>\n\t\t\t\t
