3. WINDING THE BOBBIN

The bobbin is easily wound by the fol

lowing method.

(a) Turn the stop motion knob (1) toward

you while holding the balance wheel
(2) with the left hand, loosening it
so the wheel will run free without

operating the sewing mechanism.

(b) Place the Spool on the Spool.pin (3).

Pass the end of the thread through the
Arm Thread Guide (4). Also pass it
between the discs of the tension brack
et (5). Wind the thread around the

Bobbin (6) seven or eight times, and

place the bobbin on the Bobbin winder
spindle (7). The bobbin winder auto

matically disengages when the bobbin

is about 907o full.

4. INSERTING OF THE NEEDLE

(a) Loosen the needle clamp with your right hand

and hold needle so that the flat side is to
your right. Then insert the upper part of the
needle until it hits the closed end of the

clamp,

(b) Tighten the needle clamp with your right hand.
(c) As the picture indicates, turn the needle

clamp to the left to loosen it, and turn it to
the right to tighten it.

(d) Always make sure that the long groove in the

needle is toward the left.

5. HOW TO THREAD THE NEEDLE

6. HOW TO REMOVE THE BOBBIN CASE

(a) Raise the needle bar to its highest point by

turning the balance wheel.
(b) Open the bobbin case cover.
(c) Open the latch of the bobbin case and take it

out.
(d) Close the latch of the bobbin case thus taken

out, and turn it with the open side downward.

The bobbin will drop out.

7. HOW TO INSERT THE

BOBBIN CASE

(a) Open the latch and insert the bobbin case on the

shuttle race pin. Be sure that the horn goes
into the slot in the shuttle race.

(b) Close the latch when the bobbin case has been

inserted.

(c) Be careful not to remove or insert the bobbin

case when the needle bar is lowered. The shuttle
body and the shuttle race will be damaged if

this warning is ignored. — 6 —

8. HOW TO THREAD THE BOBBIN CASE

(a) Hold the bobbin in your right hand, pull out the thread about 5 inches, and

insertin the bobbin case. (Fig. A)

(b) Pull the thread through the slot in the bobbin case as indicated in Figure B,

and pull the thread under the tension spring.

(c) Pull out the thread, and it will come out to the position indicated in Figure C.

9. HOW TO SEW STRAIGHT STITCHES

(1) Prepare for Sewing as Follows:

(a) Set the zigzag width regulating knob to "0" (zero po

sition). Now you can sew straight sewing.

(b) Hold the upper thread lightly in your left hand.

(c) Turn the balance wheel toward you gently with your

right hand, until needle enters needle plate & re
turns to highest point.

(d) When the needle bar with the thread inserted into the

needle has been raised, pull the upper thread, and

the lower thread will come out of the needle hole

picked up by the upper thread.

(e) Put both the upper and the lower thread beneath the

presser foot and pul] the ends to the back.

(2) Actual Sewing:

(a) Place the cloth to be sewn beneath the presser foot,

making one stitch by turning the balance wheel, and

lower the presser foot.

(b) Start sewing.
(c) Do not pull on the material. This often causes the

needle to break.

(3) How to Change the Direction of Sewing:

(a) Stop sewing with the needle in the cloth

(4) How to Remove the Cloth:

(b) Raise the presser foot and ^ sewing.

(5) Adjustment of the Upper and Lower Thread Tension,

( } Satisfactory seams can be produced by

being sure the upper thread and the lower
thread are knotted right in the middle of

the two pieces of material being sewn. See

Figure C.

(b) When too much tension is applied to the

upper thread, the result shown in Figure A
is produced.

(c) When too much tension is applied to the

lower thread, the result shown in Figure B

(6) How to Adjust the Tension of the Upper Thread

(b) Turn the tension disc to the right to increase the tension.

(c) j-urn it to the left to loosen the tension

(7) How to Adjust the Tension of the Lower Thread

(a) Ordinarily it is unnecessary to change the

tension of the lower thread, but there are

some fabrics that require a change.

(b) Turn the screw to the right in order

tighten the tension.

(c) Turn the screw to the left in order

loosen the tension.

(d) As it depends entirely upon the tension

whether or not you sew well, it is highly

important that you learn how to adjust the
tension as soon as possible.

(e) Use the small screw driver in your acces

sory kit to make these adjustments.

10. ADJUSTMENT OF STITCHES

AND REVERSE SEWING

(a) The figures on the indicating plate (3)

show the stitch length.

(b) Turn the knob (1) setting the desired

length of the stitch to the black-mark

on the knob (2).

(c) For reverse sewing, push the push button

reverse (4) until it stops.

11. TO USE DROP FEED DEVICE

Darning and embroidering is facilitated by means of the drop feed knob on the right
hand corner of the bed.

When this knob is set at "0", the feed teeth drop below the surface of the needle

plate so that it will not interfere with

the free movement of the cloth.
The feed teeth will return and resume their
normal operation when the knob is set at "2".

For sewing light materials like silk, it may
be set at "1" position in order to avoid
puckering the material.

-11-

12. ADJUSTMENT OF PRESSURE TO CLOTH

(a) In the case of ordinary cloth, it is seldom

necessary to adjust the pressure, but when

sewing thin or delicate materials the pressure
must be so adjusted that the cloth gets the
proper pressure. For instance, too much pres

sure will cause the material to pucker.

(b) Press down the patch-o-matic darner (A) and

the presser bar will jump up and the pressure

will release. Press down the presser bar (B)
and the pressure will become strong.

(c) You can easily adjust the pressure. In the

case of embroidering, the presser bar should
be raised to its highest point.

17. DARNING AND EMBROIDERY

Raise the presser bar lifter and remove the presBei. foot. Then lower the presser

bar lifter to ensure the thread tension device is set correctly.

Set the drop feed knob at "O",

Now your machine is ready for embroidery and darning.

Embroidery will be done most successfully when the fabric is stretched and fixed in
an embroidery hoop. Hold the hoop closely on the machine bed with both hands, press

the material with your left forefinger in the vicinity of the needle.

This will help in holding down the material and will prevent the machine from

making skipped stitches. Manipulate work carefully and be sure to keep fingers out

of the path of the needle.

Adjust thread tensions for the best appearance of embroidery work and slightly in

crease the bobbin thread tension to avoid the lower thread from being pulled up.

19. NARROW HEMMING

Turn balance wheel towards you until needle
reaches its highest point. Raise presser bar
and remove the regular presser foot. At
tach hemmer foot (Fig. 27).

1. Fold over edge of material approximately
wide, then fold it over again in the

same way for a length of about 2". Insert
this folded end from beneath into spiral
formed opening (scroll) or hemmer foot.

Move material back and forth until the
hem forms itself in the scroll.

2. Pull material towards you until the be­of the hem is just below the

needle.

3. Lower presser foot and begin to sew.

Guide material into hemmer foot while

sewing (Fig. 27).

NOTE: Do not crowd material into scroll and do not leave scroll

by material.
Feed just enough material into the hemmer foot to fill out the scroll.

Instead of a straight stitch, you can also use a zigzag stitch for this hemming

operation. Be sure however, to adjust the width of the zigzag stitch to be as

wide as the hem itself. Using a very long stitch and tight tensions will pro
duce a shell stitch.
