1. Raise the needle bar to its highest position. (Turn the fly wheel by hand toward you.)

2. Loosen needle clamp screw (A) and remove old needle.

3. Insert the needle into needle bar (B) with the flat side of the needle tow'ard the fly wheel.

CAUTION : Be sure the needle is all the way up. It should rest against the needle stop pin (C).

4. Tighten the needle clamp screw se curely with screw driver. CAUTION ; Check needle and make sure it is not bent or dull.

4. REMOVING BOBBIN CASE

1. Raise the needle bar to its highest position. (Turn the fly wheel toward you by hand.)

2. Open slide plate. With the left thumb and forefinger, open the latch (A) of the bobbin case (B).

3. Remove bobbin case from the spindle post (C). (PuU to the left.) NOTE : With the latch held open,

the bobbin is locked inside the bobbin case. To remove bobbin from the bobbin case, release the latch.

Fig. 8

5. WINDING BOBBIN

1. Hold the fly wheel (A) Fig. 7 with the left hand and turn the cluch (B) Fig. 7 toward you to release the clutch. By doing this, the

fly wheel turns freely.

NOTE : If the needle moves, the clutch is

not completely released.

2. Place thread on the spool pin and guide the thread through the upper thread guide (C) Fig. 8. Then bring the thread across the machine and under the bobbin winder thread guide (D) Fig. 8.

3. Wind the thread several times on the bobbin (E) Fig. 9. Now place the bobbin on the spindle (F) Fig. 9 of the bobbin winder.

note : The lock spring on the spindle must fit into the slot in the bobbin.

This is done by holding the rubber ring (G) Fig. 9. with the right hand and turning the bobbin with the left hand until the lock spring slips into the slot of the bobbin.

4. Push the cover (H) Fig, 9, of the bobbin winder down until the rubber ring (G) Fig, 9 is brought in contact with the fly wheel.

5. Turn the fly wheel slowly, toward you; then operate the machine as in sewing. When the bobbin is full, it will stop.

6. Remove the bobbin from the spindle, then re-engage the machine by holding

the fly wheel with the left hand and with the right hand turn the clutch away from you.

NOTE : Make sure you tighten firmly.

6 ADiUSTINO BOBBIN WINDER

]. If the thread winds unevenly on the bobbin as shown in Fig. 11 and 12, loosen

screw (A) Fig. 13 and adjust the bobbin winder thread guide bracket (B) Fig. 13.

2. If the thread winds as in Fig. 11, move the bracket slightly to the left. If the thread winds as in Fig. 12, move the bracket slightly to the right.

Fig. 10 Fig- 11 P'K- 12

7. THREADING BOBBIN CASE

1. Hold the bobbin case between the left thumb and forefinger with the slot up. With 5 or 6 inches of thread trailing in the palm, hold the bobbin between the thumb and first two fingers of right hand.

2. Insert the bobbin into the bobbin case, then pull the trailing thread into the slot, up to the left until it enters the delivery eye under the tension spring.

There should be a slight tension on the thread as it pulls through the delivery eye.

8. REPLACING BOBBIN CASE

1. Turn fly wheel toward you by hand until the needle bar is at its highest position, and open the slide plate. Draw about 3 inches of thread from the bobbin and let it hang loosely from the bobbin case.

2. With the left thumb and forefinger, hold the latch (A) of the bobbin case (B) and place it on the spindle post (C) . (Fig. 6)

NOTE ; The protruding finger (D)

must slide into the delivery eye (E) at the top of the shuttle.

3. Release the latch and press the bobbin

case to the right until it catches the

groove on the spindle post.

9. TH R EA D IN G M A CH I NE

1. Turn the fly wheel toward you and raise the take up lever (E) to its highest position. Place thread on the spool pin and bring the thread through the upper thread guide (A).

2. Bring the thread down through the thread guide to the tension disc (B) from right to left and up. Then pull

the thread up through the thread take

up spring (C).

3. Bring the thread under the thread tension guide (D) and thread the take up lever (E) from right to left.

4. Bring thread down through the thread guide (F) at the opening in the face

plate, and through the needle bar thread guide (G) from behind. Thread the needle from left to right, leaving about 5 or 6 inches of thread.

10. PREPARINO TO SEW

Fig. 18

1. Hold the loose end of the needle thread in your left hand, and turn the fly wheel toward you by hand until the needle moves down through the needle plate and up again to its highest position. Pull the needle thread gently, and the bobbin thread will come up with it through the hole in the needle plate. Then place both ends of the thread

back between the toes of the presser foot. NOTE : If the bobbin thread does not rise, check to see if there is at least 3 or 4 inches of bobbin thread hanging loosely from the bobbin case.

2. Pull the two threads at least 5 inches behind the presser foot. Place material under presser foot, and lower the foot with the presser bar lifter. Regulate the stitch to the desired size and sew. TO REMOVE MATERIAL, raise the needle to its highest position and raise the foot with the presser bar lifter, then pull the fabric back and to the left. Cut the thread with the thread cutter behind presser bar, leaving a few inches of thread behind the presser foot.

11. ADJUSTING UPPER THREAD TENSION

The correct stitch can usually be obtained by varying the upper thread tension. NOTE : TENSION ADJUSTMENT SHOULD BE MADE WITH THE

PRESSER FOOT DOTO. To increase the tension, turn the tension dial clockwise (Fig. 20). To decrease

the tension, turn the tension dial counter clockwise (Fig. 20). When the tension is properly adjusted, the upper and lower threads will cross in the center of the material (Fig. 21-A). When the upper thread tension is too tight, or the bobbin tension is too loose,

the lower thread will lay flat along the top of the material (Fig. 21-B). When the upper thread tension is too loose or the bobbin tension too tight, the upper thread will lay flat along the bottom of the material (Fig. 21-C). The tension should be adjusted little by little until the desired tension is obtained.

Fig. 21

12. ADJUSTING BOBBIN THREAD TENSION .

1. The bobbin thread tension on your machine is correctly adjusted before leaving the factory. Therefore, it is seldom necessary to alter the bobbin thread tension.

Should it become necessary to do so,

the adjusting screw of the tension spring on the outside of the bobbin case can be tightened or loosened to increase or decrease the tension of the bobbin thread.

2. To increase the bobbin thread tension, turn the adjusting screw clockwise. To decrease tension of the bobbin thread, turn the adjusting screw counter

clockwise.
