Before moving on, please reference
p. 6 to ensure proper needle and
thread size are being used for your
application.
Tension changes to the bobbin thread should
only be made when upper tension changes alone
do not solve stitch tension. In general, bobbin
tension requires just about a 2 ounce drag on
the thread (similar to what you feel when pulling
dental floss off a spool).
If knots are pulled to the top (24) and you can’t
loosen the upper tension knob (22) any more,
remove the bobbin case from the machine and
increase the bobbin case tension by tightening
the tension adjustment screw (p. 14, I). Tighten
in 1/4 increments, testing the drag on the
thread after each 1/4 turn until proper tension
is achieved.
If the knots are pulled to the bottom (25) and
you can’t tighten the upper tension knob (22)
any more, remove the bobbin case from the
machine and decrease the bobbin case tension by
loosening the tension adjustment screw (p. 14, I).
Loosen in 1/4 increments, testing the drag on the
thread after each 1/4 turn until proper tension is
achieved.
