The wound bobbin thread should be neat and
tight . If not, adjust the thread tension by turning
tension stud thumb nut of the bobbin winder tension
bracket (A) . If the
is not neat, tension
bracket (C). can be moved
to
be adjusted. When
adjusting, loosen screw (B) first,
then
move
the
bracket leftward or rightward if the thread is wound
to one side as shown in Fig.15 (b), move the tension
bracket rigtward, while if the thread is wound to
one side as shown in Fig.15 ( C ) . move the tension
bracket leftward until the thread is wound neatly as
shown in Fig.15(a), tighten screw (B).

with light tension. Otherwise bobbin (D) might be
broken or deformed.
Don

thread loosening down from the bobbin. The optimum
