Frequently Asked Questions - W1122 White

Why does the needle keep breaking?

Common causes: using a bent or dull needle, incorrect needle size for fabric, or improper insertion. Ensure the needle is straight and fully inserted with flat side away from you. Refer to the fabric/needle table on page 17 for correct size.

How do I adjust the thread tension?

Test on scrap fabric. For correct tension, upper and lower threads lock in the middle. If upper thread is too tight (lower thread visible on top), loosen upper tension dial. If too loose, tighten it. For zigzag, slightly loosen upper tension. See pages 21 and 23.

What should I do if the machine skips stitches?

Possible causes: needle not fully inserted, bent needle, wrong needle/thread for fabric, incorrect upper threading, or excess oil on hook. Check needle insertion and condition, rethread, clean hook area. See trouble chart page 48.

How do I wind the bobbin?

Place thread on spool pin, draw through thread guide and pretension device, wind around bobbin, push bobbin onto spindle, disengage handwheel, push bobbin to right, press foot controller. Machine stops when full. Retighten stop motion knob. See page 12.

How do I clean and oil the machine?

Remove needle, needle plate, and brush lint from feed dog. Remove hook race cover and hook, clean hook race with brush and cloth. Apply one drop of sewing machine oil to friction points on hook. Open face cover and oil upper parts. Run machine a few minutes after oiling. See pages 45-46.

How do I sew a buttonhole?

Set pattern dial to buttonhole positions (1-4). Mark buttonhole length (diameter + thickness + 0.3 cm). Attach buttonhole foot. Sew bar tack, left side, second bar tack, right side. Cut with buttonhole cutter using a needle to prevent over-cutting. For corded buttonholes, use filler cord. See pages 24-26.

Can I use twin needles?

Yes, for decorative tucks. Thread each needle separately: pass threads on either side of tension disc, use separate guides, and thread each needle eye. Limit zigzag width to 2.5 and set needle position to center. See page 15.

Why does the fabric not feed properly?

Check pattern selection dial setting, feed dog height, and clean lint from feed dog. If feed dog is lowered (for darning), raise it. Also ensure presser foot is down. See trouble chart page 48 and page 13 for drop feed lever.

How do I change the presser foot?

Raise presser foot lifter, set needle to highest position. For snap-on feet, push lever to release foot, position new foot under holder, lower lifter to snap on. For screw-type, loosen screw, replace foot holder, tighten screw. See page 9.

What needles and thread should I use?

Refer to the fabric/thread/needle table on page 17. For light fabrics (lace, voile): size 9 needle, silk/nylon thread. Medium fabrics: size 11-14, cotton or polyester. Heavy fabrics (denim): size 16, heavy duty thread. For knits, use ball-point needles.

Applications of Straight Stitch

A. Seams

The normal stitch length for most fabrics is 3, but the length chosen should depend on the fabric and area of usage. Usually, heavier fabrics require longer stitches, and lighter weight fabrics require shorter stitches. For curved seams and bias cut areas use a shorter stitch length to add strength and elasticity to the seam.

B. Basting/Topstitching

Sewing a seam with a longer stitch is useful for temporary seams prior to fitting. Basting stitches also may be used when gathering in fullness. Topstitching can be done very effectively with the long straight stitch. For a bolder stitch, two threads of the same type can be threaded through one needle (size 14 or 16). A heavier thread such as buttonhole twist may be used for topstitching, but be sure to use a larger needle (size 16 or 18). Basting instructions in glossary.

5. ZIGZAG SEWING

Set machine as shown.

To prevent seam ends unravelling, set machine for straight stitch and sew in reverse at beginning and ending of seam.

Zigzag Width Control

Set control at required number. Larger the number, wider the stitch.

Set it at 0 for straight sewing.

Make sure needle is in upper position when you set control.

Needle Position Control

Needle position can be changed by turning needle position control.

When selecting position, make sure needle is in upper position to avoid tearing material or bending needle.

Position	Straight stitch		Zigzag stitch(width 2.5)
				Left position:button sewing,etc.
				Middle position:straight stitch,buttonholes,etc.
				Right position:overlock,etc.

Thread Tension for Zigzag Stitch

Better-looking zigzag stitching requires less upper tension than straight stitching.

Loosen upper tension slightly.

6.MAKING BUTTONHOLES

Overlocking stitches make it possible to sew and overcast seams at the same time.

Set machine as shown.

① For medium, thin material
⑥ For medium, thick material

Put two pieces of cloth together with right sides facing and sew.

To prevent edges from fraying, sew so that right side stitches drop outside the edge of material.

In some cases overlocking stitches can be used for overcasting.

Application of Ultra Stretch Stitch

A. Seaming

On most knits, a 3/16 inch finished seam, such as stitch and overcast or the overlock stitch, is more desirable than a 5/8 inch opened seam allowance. These stitches can create a neater, more professional finish, eliminate bulky seams prevent curling, permit the garment to "give" under stress, and at the same time they cut down on the amount of work involved in making a garment. If ever in doubt as to which of the two stitches to use, test both on the particular fabric in question and choose according to their performance.

The stitch and overcast stitch is excellent for stretch fabrics such as sweater knits, bathing suit knits, and cotton knits. It has the greatest strength and elasticity of all.

For patterns with 3/16 inch seam allowances: Feed the fabric such that the needle goes over the raw edge of the fabric when it swings to the right.

For patterns with 5/8 inch seam allowances: Feed the raw edge of the fabric along the etched guide line "1/2", then trim away the excess fabric close to the stitching.

B. Procedure:

• Overlock stitching is used for seaming and finishing the cut edge of knit fabrics, all in one operation.
- This overlock stitch is especially good for stretch fabrics such as double knit and jersey and will give a firm, neat edge finish.

Application of Rick-Rack

111111

A. Topstitching/Rick-Rack

A decorative topstitch can be produced with the rick-rack stitch. Stitch around the structural lines of the garment for a special effect. Topstitch braid or a decorative inset to add an additional creative flair.

B. Tapering/Rick-Rack

The rick-rack stitch may be tapered to form creative stems and petals of flowers, embroidered pictures and wall hangings. As in tapering the zigzag, slowly turn the stitch width lever from 0 to 5 and back to 0. A group of these tapered rick-rack stitch will form a bouquet-like effect.

C. Procedure:

•The elastic rick-rack stitch is a zigzag line of stitching that is desired so that seams may be pressed open.
- Apply this stitch to areas of stress on both wovens and knits.
- Use narrow width of zigzag as a heavy duty triple stitch for seams.
- Use medium and wide widths of zigzag for overcasting edges of seams, facings and hems of heavier weight fabrics such as terrycloth, and for attaching elastic. Use also for decorative stitching.
•Guide your fabric from the front. Do not pull or push as it will cause poor stitching.

Application of Decorative Fun Patterns

A. Fun stitches-Swan-Fish-Briar

The reverse stitch patterns produce swan, fish, briar designs for use on household linens and children clothes. These reverse stitch pattern can be used to sew in hems as the scallop stitch. The reverse stitch patterns can also be used for topstitching bindings and ribbons for decorative effect. This is done in the same manner that lace is applied with the zigzag stitch. The straight stitched edge of the reverse stitch patterns on the left should be sewn on the left edge of the binding or ribbon. This decorative effect can be used on towels and placemats for a pleasant appearance. The reverse stitch patterns can also be corded for stronger decorative edges on placemats and tablecloths. Simply place four strands of pearl cotton, embroidery floss or yarn under the presser foot. A transparent foot will help guide the cord evenly while sewing the reverse stitch patterns. The reverse stitch patterns can be sewn with two threads through one needle for a more effective decorative stitch. Simply thread two sewing threads through the upper threading system. A larger needle should be used to accommodate the two threads. Use this decorative technique for enhancing tablecloths, placemats, napkins, and curtains.

NOTE: Narrow patterns may be made by setting zigzag width to 4-3-2.

10. BLIND HEM STITCH

Elastic Blind Hem Stitch

For elastic materials, set machine as shown and sew in the same way as for normal blind hem stitch.

11. STRETCH SEAMS

A ball-point needle is essential. Paper may be laid under knits for smoother feeding.

① Medium-weight fabrics double knit, jersey.

Apply elastic triple stitch.

⑥ Light-weight fabrics Apply small zigzag. Reduce upper and lower thread tension.

© For Very elastic fabrics spandex (power net)
