IMPORTANT SAFETY INSTRUCTIONS

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.

2. Always unplug before replacing a sewing machine bulb. Replace bulb with same type rated 13.2 Volts D. C. 3 Watts.

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

1. 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 owner’s manual.

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 dealers 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.

Variation of Straight Stitching

• Straight Stitch

When the machine is turned on, it’s automatically set to sew a straight stitch. This stitch can be used for regular seams, zippers, topstitching, etc.

Selected stitch w A: Zigzag foot

• Locking Stitch

Lower the needle close to the front edge of the fabric. The machine will sew several locking stitches in place and continue sewing forward. If you press the reverse button at the end of the seam, the machine will sew several locking stitches in place, then stop sewing automatically.

• Lock-A-Matic

The machine will sew four stitches forward, four stitches in reverse, then continue sewing forward. When you reach the end edge of the fabric, press the reverse button once. The machine will sew four reverse stitches, four forward stitches, then stop sewing.

• Triple Stretch Stitch

This strong, durable stitch is recommended where both elasticity and strength are needed to insure comfort and durability. Use it to reinforce areas such as crotch and armhole seams. Also use when constructing items such as backpacks for extra strength.

• Stretch Stitch

This stitch is a narrow stretch stitch designed to eliminate puckering on knit fabrics and bias seams, while permitting the seam to be pressed completely flat. The stitch can also be used to simultaneously seam and overcast when sewing on tricot and chiffons for a narrow, almost invisible seam or seam finish.

• Saddle Stitch

For topstitching suits, blazers, jumpers and denim outfits.

Adjust the Top Thread Tension

• Choose the Correct Tension

For Straight Stitch:

The ideal straight stitch will have threads locked between the two layers of fabric, as shown left (magnified to show detail). If you look at the top and bottom of the seam, you will notice that there are no gaps; that each stitch is smooth and even. When adjusting top thread tension, the higher the number, the tighter the top thread.

Results depend on;

* stiffness and thickness of the fabric * number of fabric layers * type of stitch

When Sewing Heavy Fabrics

The presser foot lifter raises and lowers the presser foot.

You can raise it about 0.7 cm (1/4" ) higher than the normal up position for easy removal of the presser foot or to help you place heavy fabrics under the presser foot.

Presser foot lifter

Pressure Adjusting Lever

The pressure adjusting lever should be set at “3” for regular sewing.

Reduce the pressure to “2” for cut work, drawn work, basting and embroidery.

Set the pressure to “1” when sewing chiffon, lace, organdy and other fine fabrics.

Velours and knits with a lot of stretch may also require a “1” setting.

x Remove the needle from the clamp.

Insert the new needle into the needle clamp with the flat side to the rear. When inserting the needle into the clamp, push it up as far as it will go and tighten the clamp screw firmly.

c To find a good needle, put 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 bent or blunt needle.

In general, fine threads and needles are used for sewing thin fabrics, and thicker threads and needles and used for sewing heavy fabrics.

Always test thread and needle size on a small piece of fabric which will be used for actual sewing.

Use the same thread for needle and bobbin.

When sewing stretch, very fine fabrics and synthetics, use a blue tipped needle. The blue tipped needle effectively prevents skipped stitches.

Overcasting

q Selected stitch w A: Zigzag foot e C: Overedge foot

* Set the stitch width at 5.0–7.0.

• Zigzag Stitch

This stitch can be used on most woven fabrics.

It’s the fastest way to finish an edge, leaving it neat and flat.

A dense zigzag can also be used for applique.

C: Overedge foot

Set the stitch width from 5.0 to 7.0 when the overedge foot C is used to prevent needle breakage or damaging the foot.

• Overcasting Variations

Multiple zigzag:

This stitch is used to finish seam allowance on synthetics and other fabrics that tend to pucker. This machine is excellent for darning and mending tears in fabric.

Knit stitch:

This stitch is recommended for sewing fabrics such as swimwear and stretch velour as it provides the greatest amount of elasticity and strength. A pressure of “1” is recommended so that the knit will retain shape as you are sewing.

Double overedge stitch:

This stitch is an excellent stitch for fabrics that tend to fray extensively such as linens and gabardines. Two rows of zigzag stitches are simulitaneously sewn over the edge to insure that your seams will not ravel.

* Set the stitch width at 5.0–7.0
