11. How to Sew Straight Stitches

(1) Prepare for Sewing as Follows :

(a) Replace the needle plate and the presser foot with those for straight sewing.

(b) Set the zigzag width regulating knob to "0" (zero position). Now you can sew straight sewing.

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

(d) Turn the hand wheel towards you gently with your right hand.

le) When the needle bar with the thread inserted into the needle hole has been roised to its

highest point, pull the upper thread, and then the lower thread will come out of the needle hole picked up by the upper thread.

(f) Put both the upper and the lower thread

Leen (c) Do not pull on the material. This often

couses 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 direc- tion 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. -

out to the other side. -

(c) Cut the edges of the upper and lower threads, Fig. 12 leaving about 5 inches free at the ends. This makes it easier to resume sewing on the next


Cc Fig. 13

(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. lb} When too much tension is applied to the upper thread, the result shown in Figure A is produced. ic) When too much tension is applied to the lower thread, the result shown in Figure B is produced, (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

Fig. 14

the tension. lc) Turn it to the left to loosen the tension. (ld) 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


(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 in the direction indicated by the arrow in order to tighen the . tension.

(c) Turn the screw in the direction indicated by the arrow in order to loosen the

tension. (d) As it depends entirely upon the tension Fig. 15

whether or not you sew well, it is highly

important that you learn how to adjust

the tension as soon as possible.

Adjustment of Feed Dog

In usual sewing the right side drop feed button (1) must be pushed down as far as it will go, then the letter ““N"' is indicated in the window (4).

When sewing thin materials such as silk, the left side drop feed button (2) must be pushed down until the red mark line (3) reaches to the surface of the plate (5).

In embroidery or button sewing, the height of the feed dog must be lower than that of the needle plate so that the cloth can be moved freely. In this case the drop feed button (2) must be pushed down entirely until the letter ““E"' appears aft the

window (4).

14. Adjustment of Pressure to Cloth




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 cloth gets the proper pressure. For

instance, too much pressure will

cause the material to pucker.

Press down the patch-o-matic dar- ner (A) and the presser bar will jump up and the pressure will become weak. Press down the presser bar (|B) and the pressure

will become strong.

You can easily adjust the pres- sure. In the case of embroider- ing, the presser bar should be

raised to its highest point.

eed=: & from the left side with the right edge of the. cloth being folded up a little.

(b) Insert the right corner so that the edge of the cloth is folded right, and pull the cloth now to the point where the needle can catch it. Lower the hemmer foot on the cloth and make some stitches slowly. With the right thumb and forefinger hold the cloth, then make a hem with the right edge of the cloth being smoothly rolled in.

1. Take care to hold the cloth right to ensure that it is always sufficiently fed in the mouth of the hemmer.

2. By sewing the cloth together with lace on the same hemmer, varied hemming can be done.

3. With wider zigzag stitches and a stronger thread tension, all kinds of edge sewing is easily done.

(Practice is required to become skilful with the use of the hemmer and all other

special attachments for sewing.)

24. 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

ia) The arrows indicate those parts to be oiled.

‘b) Just one drop ata time will do.

ic) 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 couse the machine to run heavily out also will cause wear and tear of the unit. Use only good qua- ty oil refined for use on sewing


25. The Care and Adjustment of the Motor

Attaching the Motor to the Machine

Place the motor bracket (1) on the tongue (2) over which the slot in the motor bracket ‘ts, on the arm directly under the hand wheel, as shown, so that the screw hole in the center of the tongue can be seen through the slot in the motor bracket. Then insert the

screw (3) and after shilting the motor upward as far as it will go, tighten the screw,

(2) Placing the Belt on the Motor Place the belt on the machine. Then slip the belt in the groove of the hand wheel, and force it

into the groove of the motor


Fig. 37

(3) Regulating the Belt Tension on the Motor

To adjust the belt tension, loosen the attaching screw about one turn with a screw driver. This will allow the motor to drop downward. Now firmly tighten the screw, and the belt should have the correct tension.

The method of applying oil to bearings should be varied according to the character- istics of the motor.

An oil hole is normally closed from inside with a ball. When applying oil, press the ball down with the oil can pipe, and provide a few drops of quality oil. Oiling should

be restricted only to oil holes, and under no circumstances oil any other parts.
