SELECTION
OF NEEDLES AND
THREADS
The
needle and
thread you choose
depends
upon
the fabric you
are
stitching. The
correct
selection
of
needle
and
thread
is
very
important
to
avoid
damaging
the
fabrics
of light
weight,
or
tightly
woven
fabrics,
and to
prevent
skipstitches
when sewing on
very
sheer
stretchy
fabrics or needle breakage
when
stitching
heavy
or
stiff fabrics. For best
results,
sewing
machine
needles
should
be
replaced
when
they become
even slightly
dull
or
bent
or at the
completion
of every
other garment.
A regular needle
is
suggested
for use
with
woven fabrics. Needles,
style
15 x 1, of
the
range
in
size
from 8
to
20 are used
on
this
machine.
The lower
number
indicates
the finer
needle.
The most commonly
used
sizes are
11
and
14.
A ball
point
needle is recommended
for use
with
tricots, jerseys, lingeries
and power
nets.
Unlike
sharp
pointed needles,
which pierce
fibers
of knit fabrics destroying
elasticity,the
ball
point
needle
slips between fibers
without
damage to fabric
and
skipped stitches.
A wedge
point needle
is
recommended
for use
with
leather and
leather-look vinyls.
A wedge
cutting
point
pierces
leather
more
easily
than
ordinary
sewing
machine
needles, resulting
in
more
satisfactory stitching.
Although
it is
recommended
to
use
a
ball
point
needle
for
knit
fabrics,
when
sewing
on
very
stretchy fabrics of
knits, the
underlay of a thin
paper below
the
fabric
and
the
use
of a finer
needle
are suggested
to
prevent skip
stitches.
Always
use
the
same type
and size of
thread
in
both
needle
and
bobbin.
Use
good
quality
thread
without
knots
for best stitches.

CHANGING
NEEDLE
Always
change
the
needle
after
every
other
garment
especially
when
sewing
on
polyester
and ny!on
fabrics
which
dull
needles
much
faster.
When
needles
are
dull
or
bent,
they
damage
both your
fabric
and
the
machine.
•A
general
rule
when
placing
sewing
machine
needles
is
that
the
flat
side
of.
the
needle
is
placed
to
the
right
of
the
machine,
when the
bobbin
is
put
in
from.
the
left.
If
the
needle
is
inserted
incorrectly,
the
stitches
will
not form.
To
change
the
needle
1.
Raise
the
needle
bar
to
its
highest
position
by
turning
the
hand
wheel
toward you.
2.
Loosen needle
clamp
to
remove
the
needle.
3.
Place
needle
(flat
side
to
the
right
and
long
groove
to
the
left)
in
the
neéd1
clamp
and
pysh
it
upward
as
far
as
it
will
go,
tighten
needle
clamp.
4.
After
.changing
the
needle,
make
one
complete
turn
of
the
hand
wheel
by
hand
to
be
sure
the
needle
is
clearing
the
needle
plate.
CHANGING
NEEDLE
PLATE
Although
an
all-purpose
utility
needle
plate
is
fixed
on
your
machine,
for
straight
sewing
on
fine
fabric
or
soft
or
very
stretchy
fabric,
you
may
want
to
use
the straight
stitch
needle
plate
together
with
the
straight
stitch
foot, both
of
which
are
included
in
your
accessory box.
To change
the
needle
plate,
simply
slide
the
slide
plate
as
far
leftward
as
possible.
Remove
the
two
screws
holding
the
plate
in
place. Lift
the
needle
plate
and
replace.
The
needle plate
is
removed
for
cleaning
the
lint
which
may
pile
up
between
needle
plate
and feed
dogs.

SELECTION OF
PRESSER
FOOT
CHANGING FOOT
Use the large screwdriver
to
loosen thumb
screw.
Turn the screw backward
until the
foot
becomes
loose. Then,
lift
up on
presser foot
lever
until it
is in its highest
position
in order
to
remove
the
foot.
Replace with desired
foot and tighten
thumb
screw securely.
For
most
ordinary
stitchings
the original
all-purpose
foot
can be
used.
However,
it
is
recommended
to
use following
special
foot
in
your accessory
box
whenever
you want
better stitching result.
Straight
Stitch Foot
This has only
a
narrow
hole
to ac
comodate
only straight stitching.
It may
be
u.sed
on sheer or
soft
fabrics
for
more
control. When
using
this foot, the
Stitch
Width should
be “0”
to
avoid
hitting the
foot
and breaking
the
needle.
Buttonhole Foot
This
foot has
a groove
underneath,
to
allow the narrow
satin
stitch
or button
-hole
to
form evenly.
However,
if
skip-stitch
occurs with
this foot,
apply
the underlay
of
a
thin paper
below
the
fabric.
Cording
or Zipper Foot,
and Button Foot
Use for
sewing very
close
to
the edge of
a
cord
or
zippers and
sewing
on
buttons
respectively.

0,
the

does
not
move,
resulting
in
a
bar
of
stitches formed
one
on
top
of
the
other,
as
is
used
in
button
sewing.
At
red
bar
mark
or
near

pulls
the

called
a
satin
stitch.
At

a
very
long
open

results.
IS

STRETCH STITCH
LEVER
Selection
between
ordinary
stitching
and
triple
automatic
back-and-
forth
stitching
called
stretch
stitch
is made
by the
stretch
stitch
lever.
With
the
lever
up
at
M
position,
ordinary
sewing
is performed. With
the
lever
down
at S
position, your
machine
performs
automatically
the
stretch
stitch
with
the
repetition
of
two
forward
and
one
backward
stitch combination.
A
reinforced
seam
of
stretch
stitch
that
will
stretch
considerably
more
than the
fabric
used,is
the
most
wanted
feature
in
a sewing
machine
today.
Its
uses
are
almost
unlimited
and
the
more
you
use
your
machine
the
more
it
will become
apparent
to
you.
When
stretch stitching, the
stitch
length
control
should
be
always
set
at
5.

CONTROLS:
ADJUSTING
THREAD
TENSIONS
Always
adjust
the
upper
thread
tension
with
the
presser
foot
down,
as
the
tension
is
released
when
it
is
raised.
To
increase
the
tension
on
the upper
thread, turn
tension
control
to
the
right. To
decrease,
turn to
the
left.
Before
adjusting
the
tension
be
sure
that
the
machine
is
threaded properly.
It
is
seldom
required
to
adjust
the
bobbin
thread
tension,
however, when
necessary
to
change
bobbin
thread
tension,
turn
small
screw
on side
of
the
bobbir(cae
clockwise
to
tighten
,
counterclock
wise
to
lobsen.
When
both
tensions
are
properly
balanced,
a
perfect
stitch
will
be
formed
with
both
threads
interlock
ing
in
fabric
(A).
When
the upper
tension
is
too
tight,
the
bobbin
thread
is
pulled
up
over
the
upper
thread
which
is
lying
flat
on
the
fabric
(B).
When
the
upper
tension
is
too
loose,
the
upper
thread
forms
loops
over
the bobbin
thread
lying
flat
on
the
fabric
(C).
When
the
upper
and
bobbin
thread
tensions
are
balanced
but
fabric
is
puckered
in
sewing
direction
on
sheer
fabrics,
both tensions
are too
tight.
Loosen
both
tensions
evenly.
It
is
recommended
to
adjust
the
tension
balance
under
medium
stitch
length.
In
case
of
satin
stitching for
buttonholes
and
em
broidery,
slightly loosen
the
upper
thread
tension.
