(1) Prepare for Sewing as Follows:

(a) Set the zigzag width regulating knob to "0" (zero position). 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 & returns 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 pull 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.
(b) Raise the presser foot and reverse the direction of the material.
(c) Lower the presser foot and resume sewing.

(4) How to Remove the Cloth:

(a) When the needle bar has reached its highest point, stop sewing.
(b) Raise the presser foot and pull the material out to the left.

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

(a) 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

is produced. (looping on the bottom)

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

(a) Usually perfect seams can be produced by regulating the tension applied to the upper thread.
(b) Turn the tension disc to the right to increase the tension.
(c) Turn it to the left to loosen the tension.
(d) Do not turn the disc too far at one time or irregular seams will be produced.

(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 to tighten the tension.

(c) Turn the screw to the left in order to 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 accessory 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.

Line drawing of a sewing machine needle and foot (no text or symbols)

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.

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 pressure 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.

13. REGULATING WIDTH OF ZIGZAG STITCH

The width of zigzag stitch is regulated by the zigzag width lever. By moving the zigzag width lever to desire zigzag stitch accordingly. For instance, to "0" as straight stitch. and to "5" max zigzag stitch.

Fig. 9

14. MANUAL ZIGZAG SEWING

By manually adjusting the stitch length, zigzag width while running the machine, a variety of ornamental stitches are sewo.

The following are some examples of manually sewn ornamental stitches:

Patterns	Stitch Length	Width
	any length	0
	short	5
	any length	1-5
	"	"
	long and short (repeat)	any width
	any length	5-2-5
	"	"

15. HOW TO KEEP THE MACHINE IN GOOD REPAIR

(1) Oiling

Oiling is so important that if you should be negligent in this respect you would not only shorten the machine's service life but also could cause it to become out of order.

Do not use too much oil. It is not only unnecessary but may stain or soil the material.

(2) Where to Oil

(a) The arrows indicate those parts to be oiled.
(b) Just one drop at a time will do.
(c) When you have oiled those parts indicated, run the machine for a while slowly so that the oil can penetrate and spread itself.

(3) The Quality of the Oil Used

Oil of poor quality will not only cause the machine to run heavily but also will cause wear and tear of the unit.

Use only good quality oil refined for use on sewing machines. -15-

1. Remove the regular presser foot and attach the buttonhole foot.

2. Set the zigzag width lever between "1" and "2".

Set the stitch length regulator knob to obtain close stitches (stain stitch).

1. Mark with a pencil or chalk the position and exact length of the buttonhole on the fabric.

2. Lower the needle carefully into the mark on the fabric indicating the beginning of buttonhole.

Lower the presser foot and commence sewing the left row of the buttonhole until it reaches the end of the marking. (1)

Stop the machine with needle on fabric at point A.

1. Lift the presser foot and using the needle as a pivot, turn the fabric end for end to bring the buttonhole to position (2).

2. Raise needle from fabric and drop the feed teeth by setting the drop feed knob at "0".

3. Set the zigzag width lever at "4" and sew three or four stitches to make bar-tack. (2)

4. Raise needle from fabric, also raise feed teeth by setting the drop feed knob at "2".

5. Now to sew the other row of the buttonhole, return the zigzag width lever between "1" and "2" (to its original setting) and commence to sew until your stitching reaches the position shown in figure (3).

6. To make the final bar-tack, again setting the drop feed knob at "0" and sew the bar-tack. (4)

7. Return zigzag width to "0" and take two or three stitches to fasten bar threads and prevent ravelling.

8. Remove fabric from the machine and open the buttonhole with a buttonhole cutter or seam ripper.

17. DARNING AND EMBROIDERY

Raise the presser bar lifter and remove the presser foot. Then lower the presser bar lifter to ensure the thread tension device is set correctly.

Set the drop feed knob at "0".

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 increase 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. Attach hemmer foot (Fig. 27).

1. Fold over edge of material approximately 18 " 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 beginning of 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 only partly filled 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 produce a shell stitch.

20. SEWING IN A ZIPPER

The zipper foot included in the accessories enables you to attach a zipper on fabric.

Remove the regular presser foot and attach the zipper foot to the presser bar of the machine.

First open out the zipper and place fabric in the position under the needle.

Set the machine for straight stitching.

Loosen the thumb screw (A) to set the foot on the left side of the needle and sew the left-side zipper as shown.

To sew the right-side zipper, bring the foot to the right side of the needle.
