GETTING READY TO SEW

SETrlNG UP YOUR MACHINE

When you open your Kenmore carton, you'll find the basic machine,

foot control, the instruction book you now are reading, and one box

of attachments {Accessories end ButtonholerL Set your machine on a

sturdy flat surface. Be sure to wipe off any excess oil that may have

accumulated in shipping,

Step 1: The spool pins

You'tl find Spool Pins (32) packed in

the Accassones and Buttonholer

Box. Using a screwdriver, attach

them securely at rear as indicated.

Step 2: The electrlclty

Plug Foot Controt {46) into Cord

Connection {26). Then, connect cord

into any 110-120 volt wall outlet.

Important safety notes

Your machine will not operate unless

the Power/Light Switch (28) is

turned on. This same switch controls

the machine power, sewing light, the

indicator lights on the stitch selection

panel (20) and needle controls (24

and 25). If you are interrupted or stop

sewing, turn off the switch-this is an

important safety feature that

prevents accidents.

ELECTRONIC

NEEDLE CONTROL Needle stops precisely in up or down position

The electronic control panel contains three switches. One switch provides an

electronically controlled basting or tacking to take the chore out of hand basting.

The other two switches electronically control the needle to stop in either the up

position for general sewing, or in the down position for intricate work.

1. This feature gives you the option of

stopping your machine with the

needle man up position each time.

When the needle is at this high

position, there is no possibility of the

needle becoming unthreaded when

the next seam is started. The upper

left button is pushed and lighted for

this type of sewing.

2. If you wish for the needle to remain in

the tabnc when you stop (exampte is

turning acorner), then push the lower

STITCH SELECTOR

left switch. Indicator lights quickly

show you m what position the needle

will stop, See page. 15.

The third switch labeled "'Basting"

enables you to sew very long stitches

by simply tapping the foot control-

one complete stitch will be made and

you can freely move the fabric to the

desired spot for another basting tack,

See page 16 for defin=te setting used

to accomplish this.

Push before turning dial

A) To select astitch, be sure needle is out of fabric

at its highest position. Push the stitch selector

(22) in before turning to select a stitch.

B) Then turn the dia! to left or right until the

required stitch is illuminated in red on the

indicator (20),

WINDING THE

BOBBIN A) Place thread on Spool Pin

(32) and cover with acap (32) as

shown below. To wind bobbin,

draw thread from spool through

Rear Thread Guides (34 and 36)

and the Bobbin Winder Disc (35)

as indicated below.

B) Pull end of thread through any

hole m bobbin; place bobbin on

Bobbin Winder Shaft (18) with

end of thread coming from top of

bobbin as shown above.

C) Push Bobbin Winder Latch

(19) against bobbin until it clicks.

Then pull Hand Wheel (33) away

from machine to disengage clutch

(see diagram below), Hold end of

thread coming from bobbin (see

above) and step on foot control.

After several rotations of bobbin

re_ease thread.

D) When bobbin is full, winding

stops automatically. Push in Hand

Wheel (33L Remove bobbin from

shaft and trim thread end.

Treat Hand Wheel as a "clutch"

It controls the needle mechanism

so that when pulled out, (disen-

gaged) the rest of the machine will

not operate while the bobbin fs

being wound,

Putt out to

disengage

Push in

to engage

THREADING THE

BOBBIN CASE

Drop-in bobbin

makes this a simple

sure operation

A) Make sure needle is in

highest position (this will

always be true if top left

needle position light is on).

B) Remove Bobbin Cover

Plate (4) -- just lift up the

front and it slips right out.

C) Now place the full bobbin in Bobbin Case with

thread coming off in a counter-clockwise direction.

ii_i ,_i !i_i_ii! _ D) Pull about tour inches of thread

through tension slot (shown by

arrow at left) toward back of

machine as illustrated above.

E) Replace cover plate, allowing

thread to emerge through opening

between Coverplate (4) and Needle-

plate (6). This completes bobbin

threading.

THREADING THE

REST OF YOUR

MACHINE

Upper threading ...

needle threading ...

now quick and easy

B) Now pull thread toward you

into Top-Threading Path (14),

down to Tension Spring (13) --

diagram above, Pull thread up into

spring. Then draw thread through

stotted take-up ]ever (t5} and

down again through either side of

lower thread guide (1t).

C) Making certain that needle is

in its highest position, thread it

from front to back.

D) Holding the needle thread with

the left hand, and basting button

pushed, gently tap the foot control.

A single stitch will be made. This

brings the bobbin thread up to the

top surface forming aloop. Reach

into this loop with a long instrument

like a screwdriver and pug loop free,

Then pull three or four inches of

both top and bobbin threads behind

the needle.

TENSION:

STRAIGHT STITCHING

stitching

Decrease tension Increase tension

CHECKING FOR CORRECT TENSION OF

THREAD

The good looking appearance of your straight stitching is

mainly determined by the balanced tension of the top thread

and bobbin thread. The tension is well balanced when the

two threads lock m the middfe of the layers of fabric when

straight stitching.

You can achieve balanced tension by regulating the Top

Thread Tension Control (17). if the upper thread appears to

be too tight, dial left (lower numbers) to decrease tension.

If the upper thread is too loose, dial right (higher numbers}

to increase tension.

ZIGZAG STITCHING

CHECKING FOR GOOD LOOKING ZIGZAG STITCHES

Always practice stitching on two layers of the fabr=c

you will be using.

Make sure that you are using the right size and type

of needle for the fabric. See chart page 11,

Choose a thread of good quality and type for your

fabric. See chart page 11.

Remember -- the wider the zigzag setting, the more

chance for puckering. Reduce the top tension, if

puckering occurs,

The top thread will be visible on the bottom to

varying degrees depending on the thread, fabric,

type of stitch being used and speed of sewing.

The bobbin thread should never be visible on the

top of the fabric,

BOBBIN TENSION

The bobbin tension has been correctly set at the factory, so you do not need to

adjust it.

CHANGING

NEEDLES AND

NEEDLEPLATES

Needle choice depends

on thread _,.,both

to raise Needle Bar (10) to highest posi-

tion. Loosen Needle Clamp Screw (9)

with screwdriver. Holding flat side

away from you, insert needle as far as it

will go. Tighten clamp screw securely,

using screwdriver.
