ADJUSTING STITCHING
1. As shown in the Fig.A, normal stitching shall have top and bottom threading evenly, neither over tight n or
loose. (① = Top thread; ② = Cloth; ③ = Bottom thread)
2. If the bottom threading looks like a straight line (Fig.B), which indicates the top thread is too loose. Please
turn upper thread tension dial to direction with bigger number to increase pressure until the stitching
returns to normal.
3. If the top thread looks like a straight line (Fig.C), which indicates an over-tight top thread. Please turn the
upper thread tension dial to the direction with smaller number to reduce pressure until the s titching back
