TWIN
NEEDLE
Your
sewing
machine
is
especially
constructed with
optional
twin
needle
sewing.
You
can
use
either
one
or
two colors
of
upper
thread.
When
you
use
twin
needle,
use
the
same
size
thread
and
make
sure
two
thread
spools
equal
in
weight,
otherwise
the
stitch
will
be
faulty.
Insertion
of
Twin Needle
In
the
same
manner
as
for
the
single
needle,
make
sure
that
the
flat
of
needle
faces
toward
the
back
side
and
the
long
groove
of
needle
faces
toward you.
Threading
of
Twin Needle
Follow
instructions
for
single
needle
threading
and
treat
both
threads
as
one
until
you
reach
the
needle
eye.
Pass
one
thread
through
each
needle
eye.
Important!
Use
narrow
part
of stitch
width
and
make
sure
the
twin
needle
will
not
hit
the
presser
foot
and
needle
plate,
otherwise
needle
will
break.

To form
a
perfect
stitch,
the
tension
of
upper and
lower
threads
should
be equal
so as to
lock
both threads
in the center
of
material
without
ioops
on
the
top or
bottom
of the
work.

Correct
tension
Upper

too

Lower

Upper Thread
Tension
When
the upper thread
tension
is
too tight,
the
upper thread
lies
on
the
surface
of material.
When
the lower
thread
tension
is
too tight,
the
lower
thread lies
on the
under-surface
of
material.
Lower
Thread
Tension
Usually,
perfect
seams
can be produced
by
regulating
the
upper thread
tension.
To
increase
tension,
turn the
upper
thread
tension
regulator
clockwise,
and
to decrease,
counter-clockwise.
When
adjusting
upper thread
tension,
always
lower
down
the presser
foot,
as the tension
is
automatically
released
when the
presser
foot is
raised
—12—
Ordinarily,
it is
unnecessary
to
change
the lower
thread tension
but
there
are
some fabrics
that
require
a change.
To
increase
tension,
turn
small screw
on
the
tension
spring
of the bobbin
case
clockwise,
and to decrease,
counter
clockwise.
As the
adjustment
of lower
thread
tension
is very
delicate,
do
not turn
the
small
tension
spring screw
in either
direction
more
than
about one
quarter
turn at
one
time.

NEEDLE-THREAD-FABRIC CHART
The
correct
selection
of
needle
and
thread
to
suit
the
fabric will
result
in
more
satisfactory
stitching.
Fine
fabric
should
be
stitched
with
fine needles,
fine
threads
and
short
stitches.
But
for
the
best
result
on heavier
fabrics, use
coarser
needles,
heavier
threads
and
longer
stitches.
