THE HIGHER THE NUMBER, THE LONGER THE STITCH.

To increase the stitch length, turn stitch length dial counter-clockwise to larger number on the dial.

To decrease the stitch length, turn dial clockwise to smaller on the dial.

NOTE:

1. The “0” on the dial means that the material is not being fed.

2. Always set at 4 when you sew triple stretch stitch (See page21).

ZIGZAG WIDTH

The zigzag width is regulated by operating the zigzag width lever.

Numerals above the lever represent the width of stitch.

THE HIGHER THE NUMBER, THE WIDER THE STITCH.

The “0” means straight stitch only.

NOTE: Do not move the lever while the needle is in the material.

PRESSURE ADJUSTER

Correct pressure on presser foot is important to obtain the smooth sewing.

Regulate presser according to type and thickness of the materials to be sewn.

1. To regulate the pressure, lower presser foot.

2. Push outer ring of pressure adjuster down, and inner pin will spring up to its highest position. In this position, pressure is completely released from the presser foot.

3. To increase pressure, push inner pin down with your finger.

NOTE: You will be able to select the correct combination by referring to the table below.

FEED DOG

Proper use of Feed Dog is necessary for correct sewing.

darning, embroidery, etc.

2. “UP” is used for general sewing.

REVERSE STITCH

Push the Reverse Sewing Button in as far as it will go to sew in reverse position.

Release Reverse Sewing Button and you are back to sewing in a forward position. Reverse sewing is used for tacking and reinforcement.

THREAD TENSIONS

It is important that tension of upper and lower threads be equal to prevent puckering of

material or other problems.

UPPER THREAD TENSION

To regulate upper thread tension, merely turn thread tension dial with your thumb after lowering the presser foot.

THE HIGHER THE NUMBER, THE TIGHTER THE TENSION.

To increase tension: Turn dial to right to

larger number.

To decrease tension: Turn dial to left to

smaller number.

NOTE: The zigzag stitch requires less upper tension than the straight stitch.

LOWER THREAD TENSION

Although lower thread tension has already been adjusted at the factory, when sewing very thin or heavy materials it may have to be readjusted.

To regulate the lower thread tension, turn small screw on the tension, spring of the bobbin case with the small screw driver.

To increase tension: Turn the small screw

clockwise very slightly.

To decrease tension: Turn the screw counterclockwise very slightly.

PERFECT STITCHING

Tension of upper and lower threads should

be equal, just sufficiently strong to lock

both threads in material.

Perfect stitching appears flat with no

puckering of material.

INCORRECT STITCH (A)

When the upper thread lies on the surface

of the material by pulling the lower thread

up as shown.

This is caused by tight tension on the upper

thread or loose tension on the lower thread.

To correct this, turn the upper thread tension

dial to a lower number.

If perfect stitching cannot be obtained by adjusting upper thread tension, adjust bobbin tension.

INCORRECT STITCH (B)

When the lower thread lies on the under surface of the material by pulling upper thread down as shown.

This is caused by loose tension on the upper thread or tight tension on the lower thread.

To correct this, turn the upper thread tension dial to a higher number.

If perfect stitching cannot be obtained by adjusting upper thread tension, adjust bobbin tension.

NOTE: It is recommended that a test sample

is made before starting to sew.

NOTE: Do not pull the material. Let the machine do the work. Merely guide the material with your fingers. If you pull the material, your needle might either bend or break.

HOW TO CHANGE THE SEWING DIRECTION

1. Stop machine at the turning point while the needle is in the material.

2. Raise the presser foot and turn the material to the new direction while the needle acts as the axis.

3. Lower presser foot and sew in new direction.

HOW TO FINISH YOUR SEWING PROJECT (REVERSE STITCHING)

Reverse stitching is used to reinforce stitches near the edge of material or wherever reinforcement is needed.

1. That is done by stitching to the material edge… then stopping.

2. Push Reverse Sewing Button and stitch backwards for ½ inch (10mm) from material edge.

HOW TO REMOVE FINAL SEWING FROM MACHINE

1. Stop the machine.

2. Raise needle to its highest position and make sure that the thread take-up lever is in the highest position also.

3. Lift presser foot and pull out the material gently to the left side diagonally.

4. Cut both threads on the thread cutter.

5. Leave 4 inches (10cm) of thread between the presser foot loose while the thread take-up lever is at highest position. You are ready to sew.

HOW TO GUIDE AND SUPPORT MATERIAL

Generally it is enough to guide the material in front of the presser foot as shown in the upper illustration.
