twice
daily
when
the machine
is
in continuous
operation
to
assure
free-running
and
durability
of
the

NOTE--During
the
breaking-in
period
a

CAPACITY
AND
SPEED
Consew
Model
18
is
designed
for
sewing
light
and
medium-weight
materials
in
cloth,
plastics, and
leather.
It
is
equipped
with
independently
adjustable
upper and
lower
feeding
mechanisms. As a consequence, upper and
lower
layers
of
materi<;~l
can be fed
slower
or
faster,
as
the need arises.
Maximum
possible stitch length
is
4 stitches per inch.
Maximum
operating
speed
is
1400
stitches per minute, depending
of
course
on the
type
of
material
being
sewn and its thickness.
To
assure
durability
and
troublefrce
operation,
it
is
imperative
that
for
the
first several weeks
of
operation
the maxin1urn speeJ
is
held to no more than
1
000
to
1
200
stitches in
order
to
allow
the parts
to
oecome
oropcr!y
broken in.
DIRECTION OF ROTATION
AND
OPERATING SUGGESTIONS
In
operation,
the handwheel
of
the machine
always
turns
toward
the
operator.
To
avoid
tangled
threads and jamming
of
the sewing hook,
do
not turn
hand-
wheel
otherwise.
Always
be sure that there
is
material
between
the presser feet and the feed
dog
when running the machine,
particularly
when the machine
is
fully
threaded.
The machine
will
feed
the
material
without
your
assistance.
Therefore,
do
not
pull the
iabric
as
this rnay cause damage
to
the needle.
OILING
Do
not
operate
the machine, even
if
only
for
testing, unless
it
has been
properly
oiled
at
every
spot
requiring
lubricatio'1. The
arrows
on the
follow-
ing
illustration
indicate
these spots.

..
Remember-uneven,
knotted
or
rough thread impairs the satisfactory sewing
performance
of
your
machine.
Only
left twist thread
is
to
be used
for
the needle. To test
for
twist
hold
<=!
length
of
thread between thumbs and index fingers
of
your
hands. Turn
thread counterclockwise.
If
it
will
twist
tighter,
it
has
a
left
twist.
If
it
unravels,
it
has
a right
twist.
The bobbin can be wound
with
either
left
or
right twist thread.
THREADING
THE
NEEDLE
From
the thread stand lead the thread through hole A in the spool pin on
top
of
the arm and
over
guide B at rear
of
the upper end
of
the face plate.
Now
run
it
downward
and around between the
two
tension discs C from the
back, then
over
the
wire
guide
D,
and
down
again through the
loop
of
the
check spring
E,
straight
upward
through the eye
of
the take-up lever F from the
rear,
down
again through thread guides G and H and from
left
to
right through
the eye
of
the needle. Pull about
two
to
three inches
of
thread through the
needle's eye before you begin
with
sewing.

REMOVING
AND
INSERTING
THE
BOBBIN
CASE
Pull out slide
plate,
lift
latch
of
bobbin
case
with
thumb and forefinger and
take bobbin case
out
of
machine. Bobbin
will
drop
out
when the open end
of
the bobbin case
is
held
downward
and the latch
is
released.

Fig. 4
Take bobbin case
by
the latch
after
the full bobbin
has
been ·Inserted and
place
it
on the center stud
of
the shuttle.
See
that the finger
of
the bobbin case
is
in line
with
the notch on
top
of
the shuttle race.
Release the latch and press the bobbin case
into
the shuttle until the latch
catches on the center stud
of
the shuttle. The bobbin thread should hang
down
freely
about four inches.
INSERTING A NEW
NEEDLE
Turn handwheel
toward
you until needle
has
reached the highest point
of
its travel. Loosen the needle set screw about one turn, pull
out
the
old
needle and insert a
new
one.
Push
the needle up
into
the needle bar
as
for
as
it
will
go,
setting its long groove
toward
the
left
with
eye
of
the needle
going from
left
to
right. Tighten needle set screw securely.
WINDING
BOBBINS
The
boobin w1nder
is
mounted on the table top
with
its
pulley
in
front
of
the
driving
belt
so
that the
pulley
will
separate from the
belt
after
the bobbin
has
been
wound
with
sufficient thread.
Push
the bobbin on bobbin
winder
spindle
as
far
as
it
will
go.
Pass
thread
from thread stand
downward
through eye in tension
bracket;
then between and
around the bock
of
the tension discs. Bring thread
forward
toward
bobbin
and
wind
from
below
in clockwise
direction
several times around bobbin.
Push
bobbin
winder
lever
downward
until wheel contacts the
drive
belt
and start
machine.
After
bobbin
is
filled
with
thread, release
will
cause wheel

From the library of: Superior Sewing Machine & Supply LLC
disengage from
belt
and
winding
will
stop.
Cut
thread and remove bobbin
from
winder
spindle.
Adjustment screw can be turned in
or
out
to
increase
or
decrease the amount
of
thread
wound
on the
bobbin.
When
fine thread
is
wound
on
bobbins,
use
light
tension.
by
turning the knurled nut on the tension bracket
at
the rear
winder.
Bobbin can be
wound
while
the machine
is
sewing.
THREADING
THE
BOBBIN
CASE
1.
Hold
bobbin case
between
thumb and
forefinger
of
left
hand,
so
that the slot
in
the edge
of
the bobbin case
is
on
top
as
shown in Fig.

ADJUSTING
THE
STITCH
LENGTH
The length
of
stitch
is
changed
by
movement
of
the knurled knob in the slot
at
front
of
the machine frame
(fig.
31. Turn this knob
counterclockwise
to
unlock
it
and move
it
downward
to lengthen the stitch. To
obtain
a shorter
stitch, move it in
upward
direction.
Lock knob turning
it
clockwise
after
the
correct length
of
stitch
has
been selected.
SEWING
PROCEDURE
Turn the balance
wheel
towards
you
with
the
right
hand
until
the needle
moves
down
and up again
to
its highest
point,
thus catching the
lower
(bobbin)
thread.
Now
pull the end
of
the upper thread
you
are
holding and the
bobbin thread
will
be
brought
up
with
it
through the needle hole in the needle
plate.
Place both ends
of
thread back under the presser
foot.
Place the material
to
be sewn beneath the presser
foot,
lower
the
foot
upon
it
and then start
the machine.
TO REMOVE
THE
WORK
Raise
the needle
bar
to
its highest
point;
lift
the presser
foot
and
draw
the
fabric
back and
to
the
left.
Cut
the ends
of
the threads a
few
inches long
from the needle
REGULATING
THE
THREAD TENSIONS
For
ordinary
stitching, the tension on the upper and
lower
threads should be
equal
so
as
to
lock both threads in the center
of
the
fabric.
If
the tension on
either
thread is stronger than on the
other,
imperfect
stitching
will
be the result.
If
the tension on the upper thread is
greater
than that on the
lower
there
it
will
lie
straight
along
the upper surface
of
the
fabric
If the tension on the
lower
thread
is
greater
than that on the upper
thread, the
lower
thread
will
lie
straight
along
the underside
of
the
fabric
A.
Tension
of the upper
(Needle)
thread:
Before adjusting the tension
of
the upper (needle) thread, be certain that
the presser
foot
is
let
down
and not in
lifted
position Turn serrated nut

Tension
of

it
is
rarely
necessary
to
adjust
it
ever
again.
However,
it if
should ever
require
regulation,
do
so
by
carefully
turning the single screw
located
at
the
outside
of
the bobbin case shell on
top
of
the tongue-shaped curved spring.
Turn this screw
clockwise
no more than 1
