PERFECT STITCHING The tension of the upper and lower threads should be equal and just sufficiently strong to lock both threads in the center of the work. I Perfect stitch shows flat and no puckering result on the material. e 0 INCORRECT STITCH (A) The upper thread lies on the surface of the material by pulling the lower thread up as shown. This is caused by tight tension on the upper thread or loose tension on the lower thread. To correct this, turn the upper thread tension dial to a lower number. When perfect stitch cannot be obtained by only upper thread tension dial, adjust the bobbin tension accordingly. 5 0 its 0 INCORRECT STITCH (B) The lower thread lies on the under surface of the material by pulling upper thread down as shown. This is caused by loose tension on the upper thread or tight tension on the lower thread. To correct this, turn the upper thread tension dial to a higher number. When perfect stitch cannot be obtained by only upper thread tension dial, adjust bobbin tension accordingly. NOTE: We recommend you to make test samples before starting to sew. - 15 -

threads
should
be
equal
and

INCORRECT
STITCH
(A)
The
upper
thread
lies
on
the
surface
of
the
material
by
pulling
the
lower
thread
up
as
shown.
This
is
caused
by
tight
tension
on
the
upper
thread
or
loose
tension
on
the
lower
thread.
To
correct
this,
turn
the
upper
thread
tension
dial
to
a
lower
number.
When
perfect
stitch
cannot
be
obtained
by
only
upper
thread
tension
dial,
adjust
the
bobbin
tension
accordingly.
INCORRECT
STITCH
(B)
The
lower
thread
lies
on
the
under
surface
of
the
material
by
pulling
upper
thread
down
as
shown.
This
is
caused
by
loose
tension
on
the
upper
thread
or
tight
tension
on
the
lower
thread.
To
correct
this,
turn
the
upper
thread
tension
dial
to
