Oiling

must be done

at

least

twice

daily

when

the machine

is

in continuous

operation

to

assure

free-running

and

durability

of

the

operating

ports.

NOTE--During

the

breaking-in

period

a

new

machine should be

oiled

more

frequently.

needles

for

sewing

cloth

and 16 X

for

leather

and plastics

ranging

in sizes

from

14

to

The

thickness

of

the

sewing

thread,

which

must pass

freely

through

the

eye

of

the

needle,

determines the size

of

clean

of

protective

grease and

lubricate

all

with

a

good

grade

of

sewing

machine

!see

below!.

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.

3 -

.,...,

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

to

-4-

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

it

ever

again.

However,

it if

do

so

by

carefully

outside

of

the bobbin case shell on

top

of

the tongue-shaped curved spring.

Turn this screw

clockwise

no more than 1
