INSTRUCTION
MANUAL
FOR
ZIGZAG
INTRODUCTION
Your
Zigzag
sewing
machine
is the
product
of
many
years
of
research
and
development
in
the
field
of
household
sewing machines.
It
is
also
the
ultimate
in
efficiency,
quality
and
design,
yet
its
moving
and
wearing
parts
such
as
needles,
bobbins,
bobbin
cases,
hooks
and
so
forth
are
standard
and
interchangeable
with
parts
immediately
at
sewing machine
stores
throughout
the
world.
This
precision
sewing
head, with
its
simplified
design
and
many
labour saving
extras,
is
the
result
of
our
incessant
exertion
and each machine
is
built
to
the
most
exacting
specifications
under
our
rigid
quality
control
program.
\ou
have
made
an
excellent
choice
and
you
are
deserved
of
the
proud
owner
of
Super
Dc
Luxe
sewing
machine, which
will
surely
lead
to
your
happy
life.
You
will
SOOti
realize
how
quickly
you
will
become
attached
to
your
new
machine
as
a
friend
of
the
family who really
lends
you
a
band.
The
ingenious
construction
makes
it
possible
to
do
many
jobs
on
the
new
machine
which until
now
had
to
be
done
by
hand.
—

SAFE
GUARD THE
ACTION
OF
YOUR
MACHINE
Make
sure
the balance
wheel
always
turns
toward
the
operator.
Never
run
the
machine
with
the
presser
foot
in
the
down position
without
cloth between
the
presser
foot
and the
feed dog.
Never
run
machine
when
the
bobbin case and
the
needle are
threaded
without
first placing
material
under
the
presser
foot.
Caution, never
try
to
help
the
machine
feed
by
pulling
the material
through
the
feed.
This
will
create
a
bent needle
condition.
The
machine’s
feed
is
entirely automatic.
Never
operate
the
machine
without
the
hook
race
cover the
bobbin
case
in
position.
Keep
a
small
piece
of
cloth
underneath
presser
foot
whenever
machine
is
not
in use.
This
will
prevent
damage
to
feed
dog
and
presser
foot.
Do
not
operate machine when
presser
foot
lever
is
raised.
Keep
slide
or
hinged
closed
when
operating
machine.

TO WIND
THE
BOBBIN
It
is
necessary
to
understand
the
function
of
the
Stop Motion
by
means
of
which
the
balance
wheel
is
disconnected
from
the
sewing
mechanism, when required,
thus permitting
the
winding
of
the
bobbin
without
sewing.
a)
Turn
the
stop motion
knob
toward
you
while
holding
the
balance
wheel with
the
left
hand.
This
will
then
permit
the
balance
wheel
to
turn
freely
while
the
needle bar
remains
motio
nless.
b)
Place
a
spool
of
thread
on
the spool pin
at
backside
of
arm.
c)
Pass
the
thread through
the
notched thread
guide (3).
d)
Draw
the
thread
down
through
the
bobbin
winder
thread
guide
(16)
at
right
corner
of
the
base
of
machine.
e
Now wind
the
end
of
the
thread around
an empty
bobbin
seven
or
eight
times
and
place
threaded
bobbin
on the
spindle (C)
of
the
bobbin winder.
f)
Press
the
bobbin
into
the
spindle
with
the
left
hand,
making
sure
that
the
Pin
on the
spindle
fits
into the
slot
in
the
bobbin.
g)
Push
the
bobbin
winder
levever
(D)
down until
the
small
rubber
wheel
presses
against
the
hub
of
the
balance
wheel and the clasp
(E)
falls
between
the
sides
of
the
bobbin
holding
it
in
position.
h)
Turn
the
balance
wheel
toward
you
and
run
the
machine
as
in sewing.
When
bobbin
is
full,
the
bobbin
winder
will
automatically
stop.
i) Break
off
the
thread
and
detach
the
bobbin
from
the spindle.
j)
Hold
the
balance
wheel
firmly
with
left
hand
and
with
right
hand
turn
the
stop
motion
knob
away
from
you
until
the
machine
is
tight
and then
the
needle bar
moves with
the
turning
of
the
balance
wheel.
You
can
perform
this
operation
also
when
the
machine
is
working.
In
this
case
you
will
operate
in
the
same
way
as
explained
above,
but
without
disconnecting
the
balance
wheel.
