machine
is
the product
of
many
years
of research
and
development
in the
fiçld
of household
sew
ing

The
highest
quality materials
have
been
used
to assure

this
machine,
it
is
important
that
you
be
come
completely
familiar with
its
various
features,
controls and
adjustments.
The
time you

the
two
electrical
plugs
to
the
electrical
socket
in
the
base
of
the
portable
case,
or on
the
inside
right
hand
panel
of
the
cabinet
on
console
models.
NOTE:
Be

in
serted
in
the
socket
labeled
“motor”
and
that
the
cord
from
the
light
is inserted
in
the
socket labeled
“light”.

cord
running
from
this
socket
should
then
be inserted
in the
wall
receptacle.
Before
actually
sewing.
it
is
recommended
that
you
practice

material
and
use
of
the electrical
con
troller.
To
prevent
damage
to
the
presser
foot
and
material

IS
PLACED
TO
WARD

BACK,
OR
TOWARD
THE
REAR
OF
MACHINE.
See
Fig.
&
Now
insert
the
needle
in the
clamp
as
far
as it will go
and
retighten
thumb
screw.
This
machine uses
needles classified
as
AA,
or 15x1
which
can be
obtained
in
various
sizes
for different
size threads and
purposes.
See Chart,
Page
7.
It is
important
that
the
proper
size
of
thread
be
used.
Make
certain
that the
same
size and
quality
of thread
is
used
in both
the
upper
spool
and
the
bobbin.
This will
prevent faulty
sewing.
“Bargain”
thread is
poor
economy.
In
many
cases,
such thread
has tiny knots
which
interfere
with the
free flow
of the thread
through
the thread
ing mechanism
and
needle.
High
quality
thread is
most
desirable
to
achieve
perfect
sewing
results.
HOW
TO CHOOSE
NEEDLE
AND
THREAD
The quality of the
seam made by your
sewing
machine depends
largely upon the
proper
selection of needle and
thread size.
Both should be
matched as closely as
pos
sible to the type
of fabric
you
intend to
sew.
See
Chart, Page
7. Heavy
material requires
a
thicker
needle and coarser
thread,
while
finer fabric
calls for
a
thinner needle
and
finer thread.
Using
a
needle that
is
too
thick
will leave marks
on the
cloth. A needle
which is
too thin will not allow
the
thread
to
pass
freely through the
eye
of
the needle.
Always
make
sure that the
needle in your
machine
is
not bent
and does not
have
a
blunt or
hook-shaped
point
It is highly
important that
the correct
SIZE of needle
be
chosen
for
the sewing to
be
done.
Refer
to Chart, Page
7.
This
Chart, in fact,
indicates the
proper SIZE
of needle for various
types
of
sewing.
Equally
important, when
purchasing re
placement
needles, make
certain that they
are the
correct
LENGTH. The
diagram
below shows
the correct LENGTH
(ljj”)
to scale.
If
a
needle is used
which
is
not of.
the
correct
LENGTH.
it is
impossible
to
secure
perfect sewing
results. In
fact,
a
needle
of incorrect
LENGTH
will
cause
you
endless
trouble.

HOW
TO
REGULATE
DIRECTION
OF

the opposite
direction,
or
from
the
rear

This allows
reversal
of

by
pressing

HOW
TO
PREPARE
FOR SEWING
Raise
the
presser
bar.
Hold
end
of
needle
thread
in
the
left
hand loosely (See Fig.
13).
Then
with
the right
hand
turn
the
balance wheel
toward
you
until the needle
has
moved down
and
up
again
to
its
high
est
position.
In this operation
the
needle
thread
will
catch the
bobbin
thread
draw
ing
it
up
through
the
hole
in
the
throat
plate.
With
the
left hand
pull up
the
needle
thread
to
expose
the
bobbin
thread
(See
Fig. 13).
Take
both threads
with
your
hand
and
draw
them,
under
the
presser
foot,
toward
rear
of
machine. Now
place
material
to
be
sewn
i.incler
presser
foot and
lower
the
presser
foot.
When the
presser bar
is
in
the
down posi
tion
the
thread
should extend
towards
the
back
of
the
machine,
between
the
toes of
the
presser foot, and should
be
firmly
held be
tween
the
feed
and the
presser foot.
Once
the
material
and
threads
are
in
position
with
presser
foot lowered
on
to
material,
you
are
ready
to
start the
actual
sewing
operation.
NOTE:
1.
Have
take-up
lever
at
highest
point
before starting
the
sewing
operation.
2.
Do
not
try to
help the
feeding
of
the
work by
pulling
the
ma
terial as
this may deflect
the
needle
and cause
it
to
break.
The machine
feeds without
as
sistance.
3.
After
threading,
NEVER
run
machine
without
material
be
tween
presser
foot
and
feed
dog.
