Solution
Increase the tension by
turning the upper tension-
control dial to a higher
number.
Note
● If the loops still appear on the wrong side of
the fabric after you adjust the upper tension,
the bobbin thread may be too tight. In this
case, turn the screw counterclockwise being
careful not to over-loosen the screw,
approximately 30-45 degrees to decrease
bobbin tension. After you adjust the bobbin
thread, adjust the upper thread to match the
bobbin thread.
