□ Thread Tension

Upper thread tension

Basic thread tension setting: "4".

To increase the tension, turn the dial to the next number up.

To reduce the tension, turn the dial to the next number down.

1. Normal thread tension for straight stitch sewing.
2. Thread tension too loose for straight stitch sewing. Turn dial to higher number.
3. Thread tension too tight for straight stitch sewing. Turn dial to lower number.
4. Normal thread tension for zigzag and decorative sewing. Correct thread tension is when a small amount of the upper thread appears on the bottom side of fabric.

Lower thread tension

The bobbin tension has been set correctly at the factory, so you do not need to adjust it.

Please note:

• Proper setting of tension is important to good sewing.
• There is no single tension setting appropriate for all stitch functions, thread or fabric.
• A balanced tension (identical stitches both top and bottom) is usually only desirable for straight stitch construction sewing.
• 90% of all sewing will be between "3" and "5".
• For zig zag and decorative sewing stitch functions, thread tension should generally be less than for straight stitch sewing.
• For all decorative sewing you will always obtain a nicer stitch and less fabric puckering when the upper thread appears on the bottom side of your fabric.

Technical diagram of a sewing machine with numbered parts for identification

□ Threading the Upper Thread

This is a simple operation but it is important to carry out correctly as by not doing so several sewing problems could result.

• Raise the needle to its highest position by turning the handwheel towards you (counterclockwise) so that the mark on the handwheel points directly up. Raise the presser foot to release the tension discs. (1)
  Note: For safety, it is strongly suggested you turn off the power before threading.
• Lift up the spool pin. Place the spool of thread on the holder with the thread coming off the spool as shown. For small thread spools, place small side of spool holder next to spool.(2)
• Draw thread from spool through the upper thread guide (3) and pulling thread through pre-tension spring as illustrated. (4)
• Thread tension module by leading thread down right channel and up left channel. (5) During this process it is helpful to hold the thread between the spool and thread guide.
• At the top of this movement pass thread from right to left through the slotted eye of the take-up lever and then downwards again. (6)
• Now pass thread behind the thin wire needle clamp guide (7) and then down to the needle which should be threaded from front to back.
• Pull about 6-8 inches of thread to the rear beyond the needle eye. Trim thread to length with built in thread cutter. (8)

□ Stitch Length Dial

Function of stitch length dial for when straight stitching

For straight stitch sewing, turn the Pattern Selector Dial to the straight stitch setting. (1)

Turn the Stitch Length Dial, and the length of the individual stitches will decrease as the dial approaches "0". The length of the individual stitches will increase as the dial approaches "4". (2)

Generally speaking, use a longer stitch length when sewing heavier weight fabrics or when using a thicker needle or thread. Use a shorter stitch length when sewing lighter weight fabrics or when using a finer needle or thread.

Function of stitch length dial while zig-zag stitching

Turn the Pattern Selector Dial to " \~" . (3)

The density of zig-zag stitches increases as the setting of stitch length dial approaches "0".

Neat zig-zag stitches are usually achieved at "2.5" or below.

Dense zig-zag stitches are called satin stitches. (4)

□ Blind Hem

For hems on curtains, trousers, skirts, etc.

Blind hem for stretch fabrics.

Blind hem for firm fabrics.

Note:

It takes practice to sew blind hems. Always make a sewing test first.

Set the stitch length dial with the range shown on the diagram at the right. Blind hems, however, are normally sewn with a longer stitch length setting.

Generally, a narrower stitch is used for lighter weight fabrics, and a wider stitch is used for heavier weight fabrics. Sew a test first to make sure the machine settings are appropriate for the fabric.

Blind Hem:

Turn up the hem to the desired width and press. Fold back (as shown in Fig. 1) against the right side of the fabric with the top edge of the hem extending about 7 mm. (1/4") to the right side of the folded fabric.

Start to sew slowly on the fold, making sure the needle touches slightly the folded top to catch one or two fabric threads. (2)

Unfold the fabric when hemming is completed and press.

Note:

To make blind hem sewing even easier, use a blind hem foot, available from your SINGER ^® retailer.

□ Buttonholes

Prepare

1. Take off the all purpose foot and attach the buttonhole foot.
2. Measure diameter and thickness of button and add 0.3 cm (1/8") for bar tacks to obtain correct buttonhole length; mark buttonhole length on fabric (a).
3. Place fabric under the foot, so that marking on the buttonhole foot aligns with starting marking on fabric. Lower the foot, so that the buttonhole center line marked on the fabric aligns with the center of the buttonhole foot (b).

Adjust the stitch length dial in the " 🔊" range to set stitch density.

Note:

Density varies according to the fabric.

Always test sew a buttonhole on the fabric you are using to sew the buttonhole.

Follow the 4-step sequence changing from one step to another with the Pattern Selector Dial. When moving from step to step through the buttonhole process, be sure that the needle is raised before turning the Pattern Selector Dial to the next step. Take care not to sew too many stitches in steps 2 and 4. Use seam ripper and cut buttonhole open from both ends towards the middle.

Tips:

• Slightly reducing upper thread tension will produce better results.
• Use a stabilizer for fine or stretchy fabrics.
• It is advisable to use heavy thread or cord for stretch or knit fabrics. The zig-zag should sew over the heavy thread or cord. (A)

STITCH LENGTH 0 1 2 3 4 1 2 3 4

□ Sewing on Buttons

Install the darning plate. (1)

Change the all purpose foot to the button sewing foot. (2)

Set the stitch length to "0".

Place the button and fabric under the Button Sewing foot, as illustrated in (3).

Set the machine for zig-zag stitch. Adjust the dial until the needle moves from the left hole into the right hole of the button without interference. Turn the handwheel to check that the needle goes cleanly into the left and right holes of the button. Slowly sew on the button with about 10 stitches.

Raise the needle out of the fabric. Set the machine for straight stitch again, then sew a few securing stitches to finish.

If a shank is required, place a darning needle on top of the button and sew. (4)

For buttons with 4 holes, sew through the front two holes first, push the work forward and then sew through the back two holes.
