Winding the Bobbin 

  • Place the thread and spool pin felt (a) onto the spool pin. (1)
  • Draw the thread from the spool through the upper thread guide. (2)
  • Wind the thread clockwise around bobbin winder tension discs. (3)
  • Thread bobbin as illustrated and place on spindle. (4)
  • Push bobbin spindle to right. (5)
  • Hold thread end. (6)
  • Step on foot control pedal. (7)
  • Release the pedal after a few turns. Release the thread  and cut as close as possible to the spool. Press the pedal again. Once the spool is full, it rotates slowly. Release the pedal and cut thread. (8)
  •  Push bobbin spindle to left (9) and remove

Please Note:
When the bobbin winder spindle is in “bobbin winding” position, the machine will not sew and the hand wheel will not turn. To start sewing, push the bobbin winder spindle to the left (sewing position).

Inserting the Bobbin

When inserting or removing the bobbin, the needle must be fully raised

  • Open the hinged cover. (1)
  • Pull the bobbin case tab (a) and remove the bobbin case. (2)
  • Hold the bobbin case with one hand. Insert the bobbin so that the thread runs in a clockwise direction (arrow(3)
  • Pull the thread through the slit and under the finger. Leave a 6 inch tail of thread. (4)
  •  Hold the bobbin case by the hinged latch. (5)
  •  Insert it into the shuttle. (6)

Turn power switch to off (“O”) before inserting or removing the bobbin

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)
  • Place the thread and spool pin felt (a) onto the spool pin. (2)
    Note: For safety, it is strongly suggested you turn off the power   before threading.
  • Draw the thread from the spool through the upper thread guide. (3)
  • Guide the thread around the thread guide 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)

Raising the Bobbin Thread 

Hold the upper thread with the left hand. (1) Turn the handwheel towards you (counterclockwise) lowering, then raising needle.

If it is difficult to raise the bobbin thread, check to make sure the thread is not trapped by the hinged cover or the Removable Extension Table.

Gently pull on the upper thread to bring the bobbin thread up through the needle plate hole. (2)

Lay both threads to the back under the presser foot. (3)

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 zig zag 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.

How to Choose Your Pattern

To select a stitch, simply turn the pattern selector dial. The pattern selector dial may be turned in either direction.

For straight stitch, select pattern ” ” with the pattern
selector dial.

For zigzag stitch, select pattern ” ” with the pattern

selector dial.

  1.  Pattern Selector Dial
  2.  Reverse Sewing Lever

Sewing Straight Stitch

  • To begin sewing, set the machine for straight stitch. (1)
  • Place the fabric under the presser foot with the fabric edge lined up with the desired seam guide line on the needle plate. (2)
  • Lower the presser foot lifter, and then step on the foot control to start sewing. (3)

Reverse Sewing

To secure the beginning and the end of a seam, press down the reverse sewing lever (A). Sew a few reverse stitches. Release the lever and the machine will sew forward again. (1)

Removing the Work 

Turn the handwheel toward you (counterclockwise) to bring the thread take up lever to its highest position and the needle begins to descend, raise the presser foot and remove work behind the needle and presser foot. (2)

Cutting the Thread

Pull the threads under and behind the presser foot. Guide the threads to the side of the face plate and into thread cutter (B). Pull threads down to cut. (3)

Blind Hem

  • For hems on curtains, trousers, skirts, etc.
  • Blind hem for stretch fabrics.
  • Blind hem for firm fabrics.

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

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.

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



  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).

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.


  • 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)

Sewing on Buttons

Install the darning plate. (1)
Change the all purpose foot to the button sewing foot(2)

Position the work under the foot.
Place the button in the desired position and lower the foot. Set the Pattern Selector Dial for the second zig-zag pattern (as shown), which should correspond to the distance between the two holes of the button. Turn the handwheel toward you to check if the needle goes into the right and left hole of the button without hitting the button. Slowly sew on the button with about 10 stitches. (3) Bring the thread tails to the back of the work, then tie off manually

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.

Zippers and Piping

Set the machine as illustrated.

Change to zipper foot.

The zipper foot can be attached right or left, depending on which side of the foot you are going to sew. (1)

To sew past the zipper tab, lower the needle into the fabric, raise the presser foot and push the zipper tab behind the presser foot. Lower the foot and continue to sew.

It is also possible to sew a length of cord into a bias strip to form a “welt” or piping. (2)

Free Motion Darning, Stippling

  • * The darning/ embroidery foot is an optional accessory not included with your machine. (1)

Install the darning plate. (2)

Remove the presser foot shank. (3)
Attach the darning/ embroidery foot to the presser foot bar. The lever (a) should be behind the needle clamp screw (b). Press the darning/ embroidery foot on firmly from behind with your index finger and tighten the screw (c). (4) For darning, first sew around the edge of the hole (to secure the threads). (5)
First row: Always work from left to right. Turn work by 90 degrees and sew over previous stitching. A darning hoop is recommended for easier sewing and better results.

Free motion darning is accomplished without the sewing machine internal feed system. Movement of the fabric is controlled by the operator. It is necessary to coordinate sewing speed and movement of fabric.

Set the machine for straight stitch. Using the optional darning/ embroidery foot will help guide you as you sew, in a meandering fashion to create small curving lines to hold layers of fabric and batting together.
