ADJUSTING THE STITCH
Normal stitching shall have top and
bottom threading evenly, neither
over tight nor loose.
If the bottom threading looks like
a straight line, it indicates that 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.
If the top thread looks like a
straight line, it indicates an
over-tight top thread. Please
turn the upper thread tension
dial to the direction with
smaller number to reduce
pressure until the stitching
returns to normal.
