When using an electrical appliance, basic safety precautions should always be followed, including the followings:

Read all instructions before using this appliance.

DANGER—

To reduce the risk of electric shock:

1. An appliance should never be left unattended when plugged in. Always unplug this sewing machine from the electric outlet immediately after using and before cleaning.

WARNING—

To reduce the risk of burns, fire, electric shock, or injury to persons:

1. Do not allow children to play with the machine. The machine is not intended for use by children or infirmed persons without proper supervision. Do not allow to be used as a toy. Close attention is necessary when this sewing machine is used by or near children.

2. Use this appliance only for its intended use as described in this owner's manual. Use only attachments recommended by the manufacturer as contained in this instruction book.

3. Never operate this sewing machine if it has a damaged cord or plug, if it is not working properly, if it has been dropped or damaged, or dropped into water. Return this sewing machine to the nearest authorized dealer or service center for examination, repair, electrical or mechanical adjustment.

4. Never operate the appliance with any air opening blocked. Keep ventilation openings of this sewing machine and foot controller free from accumulation of lint, dust and loose cloth.

5. Never drop or insert any object into any opening.

6. Do not use outdoors.

7. Do not operate where aerosol (spray) products are being used or where oxygen is being administered.

8. To disconnect, turn all controls to the off ("O") position, then remove plug from outlet.

9. Do not unplug by pulling on cord. To unplug, grasp the plug, not the cord.

10. Keep fingers away from all moving parts. Special care is required around the sewing machine needle.

11. Always use the proper needle plate. The wrong plate can cause the needle to break.

12. Do not use bent needles.

13. Do not pull or push fabric while stitching. It may deflect the needle causing it to break.

14. Switch this sewing machine off ("O") when making any adjustment in the needle area, such as threading the needle, changing the needle, threading the bobbin or changing the presser foot, and the like.

15. Always unplug this sewing machine from the electrical outlet when removing covers, lubricating, or when making any other adjustments mentioned in this owner's manual.

NOTE:

The feed dog should be in the up position for regular sewing. Turn the handwheel toward you to check if the feed dog comes up after setting the lever in the up position.

Changing the Presser Foot

CAUTION:

Turn OFF the power switch before changing the foot. Always use the proper foot for the selected pattern. The wrong foot can cause the needle to break. Do not push the lever down to prevent it from being broken.

To snap off:

Raise the needle and presser foot. Press the lever on the back of the foot holder and the foot will drop. ① Lever

To snap on:

Place the presser foot so the pin on the foot lies just under the groove of the foot holder. Lower the foot holder to lock the foot in place.

Detaching and Attaching the Foot Holder

WARNING:

Turn OFF the power switch before detaching or attaching the foot holder.

To detach:

Raise the presser bar and turn the setscrew counterclockwise to remove the foot holder.

① Setscrew
② Foot holder

To attach:

Align the hole in the foot holder with the threaded hole in the presser bar and insert the setscrew through the hole.

Raising and Lowering the Presser Foot

The presser foot lifter raises and lowers the presser foot.

You can raise the presser foot about 1/4" (0.6 cm) higher than the normal up position by exerting more pressure when lifting the presser foot lifter. This allows for easy removal of the presser foot and helps you to place thick fabric under the foot.

① Presser foot lifter
② Normal up position
③ Extra lift

Balancing Thread Tension

The thread tension should be adjusted depending on the sewing materials, layers of fabric and sewing method.

To adjust the thread tension, turn the tension dial.

① Tension regulating dial
② Setting mark

Balanced tension:

The ideal straight stitch has threads locked between two layers of fabric. For an ideal zigzag stitch, the bobbin thread does not show on the right side of the fabric, and the needle thread shows slightly on the wrong side of the fabric.

③ Needle thread
④ Bobbin thread
⑤ Right side of the fabric
⑥ Wrong side of the fabric

Needle thread tension is too tight:

-if the bobbin thread appears on the right side of the fabric.

Loosen the needle thread tension by moving the dial to a lower number.

Needle thread tension is too loose:

-if the needle thread appears on the wrong side of the fabric. Tighten the needle thread tension by moving the dial to a higher number.

Changing Needles

Technical diagram showing four-step assembly steps of a mechanical tool, with numbered instructions and directional arrows indicating motion.

WARNING:

Always make sure to turn the power switch off and disconnect the machine from power supply before changing the needle.

Raise the needle by turning the handwheel and lower the presser foot. Turn off the power switch.

1 Loosen the needle clamp screw by turning it counterclockwise.
Remove the needle from the clamp.
① Needle clamp screw

2 Insert a new needle into the needle clamp with the flat side of the needle to the rear.

When inserting the needle into the needle clamp, push it up against the stopper pin and tighten the needle clamp screw firmly.

② Stopper pin

③ Flat side

To check needle straightness, place the flat side of the needle onto something flat (a needle plate, glass etc.) The gap between the needle and the flat surface should be consistent.

Never use a blunt needle.

Sewing from the edge of thick fabric

The black button on the zigzag foot locks the foot in the horizontal position.

This is helpful when starting sewing from the extreme edge of thick fabrics or sewing across a hem.

Lower the needle into the fabric at the point where you wish to start sewing.

Lower the foot while pushing in the black button. The foot will be locked in the horizontal position to avoid slipping.

The foot will be unlocked after sewing a few stitches.

Buttonholes

#14 Square buttonhole (sensor buttonhole)

This buttonhole is widely used on medium to heavy weight fabrics.

The buttonhole size is automatically determined by placing a button in the rear of the foot.

#15 Auto buttonhole

This is also a square buttonhole similar to the Sensor Square Buttonhole, but you can manually set the buttonhole size and you can memorize the size to sew buttonholes of the same size.

Machine Settings

① Stitch pattern: #14
② Foot: Automatic buttonhole foot R
③ Thread tension: 1 - 5

NOTES:

• The size of a buttonhole is automatically set by placing a button in the rear of automatic buttonhole foot R.
• The button holder of the foot takes a button size of 3/8" (1 cm) to 1" (2.5 cm) in diameter.
• It is sometimes necessary to change the buttonhole size to match certain heavy or specific fabrics and threads.
• Make a test buttonhole on an extra piece of the fabric to check your settings.
• The preset width of the buttonhole is suitable for ordinary buttons.
• Apply an interfacing to stretch or fine fabrics.

2 Pull the button holder to the back, and place the button in it. Push it together tightly to the button.

NOTE:

If the button is extremely thick, make a test buttonhole on an extra piece of the fabric. If it is difficult to fit the button through the test buttonhole, you can lengthen the buttonhole by pulling the button holder back a little. The length of the buttonhole will be increased.

① 3/8"(1cm)

A looser needle thread tension will make gathering easier.

Knot the threads along one edge. From the other end, pull the bobbin threads to distribute the gathers evenly. Secure the threads at the other end.

Sew the smocking stitches between the straight seams.

Remove the straight stitches by pulling them out.

Correcting Distorted Stretch Patterns

The sewing results of the stretch patterns may vary depending upon the sewing conditions, such as sewing speed, type of the fabric, number of layers etc.

Always test sew on a scrap piece of the fabric that you wish to use.

If stretch stitch patterns are distorted, correct it with the feed balancing dial.

② Neutral position
③ Setting mark

Example: Pattern #10

(A) If the pattern is compressed, turn the feed balancing dial in the direction of "+".
(B) If the pattern is drawn out, turn the feed balancing dial in the direction of “—”.
