Threading the Machine

Winding the Bobbin

• Place thread and corresponding spool holder on to spool pin.
  
• Snap thread into thread guide.
  
• Wind thread clockwise around bobbin winder tension discs.
  
• Thread bobbin as illustrated and place on spindle.
  
• Push bobbin spindle to right.
  
• Hold thread end.
  
• Step on foot control pedal.
  
• Cut thread.
  
• Push bobbin spindle to left and remove.
  

Please Note:
When the bobbin winder spindle is in "bobbin winding" position, the machine will not sew and the handwheel 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.

1. Insert the bobbin in the bobbin case with the thread running counterclockwise direction (arrow).
   
2. Pull the thread through the slit (A).
   
3. Draw the thread clockwise until it slips into the notch (B).
   
4. Pull out about 15 cm (6 inches) of thread and attach the bobbin cover plate. (C)
   

Attention:
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.

• Start by raising the needle to its highest point (1), and continue turning the handwheel counterclockwise until the needle just slightly begins to descend. Raise the presser foot to release the tension discs.
  
  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.
  
• 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.
  
• Now pass the thread behind the horizontal thread guide, and then 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.
  

Automatic Needle Threader

• Raise the needle to its highest position.
• Press lever (A) down as far as it will go.
• The threader automatically swings to the threading position (B).
• Pass thread around thread guide (C).
• Pass the thread in front of the needle around the hook (D) from bottom to top.
• Release lever (A).
• Pull the thread through the needle eye.

Attention:
Turn power switch to off ("O")!

Raising the Bobbin Thread

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

Note: 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.

Lay both threads to the back under the presser foot.

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 tension setting is important for strong seams
• 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.

Sewing

How to Choose Your Pattern

The diagram display the stitch patterns available on the machine.

Stitches in the top of the diagram are indicated on the Pattern Selector Dial in gray. To select the patterns indicated with the gray color, turn the Pattern Selector Dial. (e) Use the Stitch Length Dial (d) to adjust the stitch length as desired for the project. Use the Stitch Width Dial (c) to adjust the width of the stitch as desired.
To obtain the other patterns, turn the stitch length dial to "S1" or "S2", select the pattern desired with pattern selector dial, and adjust the stitch width with the stitch width dial.
The Pattern Selector Dial may be turned in either direction.

1. Reverse Sewing Lever
2. Three Needle Position Dial
3. Stitch Width Dial
4. Stitch Length Dial
5. Pattern Selector Dial

Three Needle Position Dial

The needle position can be altered with the "Three needle position dial". For normal work, the needle position is middle. For edge stitching or sewing parallel lines of top stitch, select needle position left or right. For twin needle stitching, needle position is middle.

1. Straight
2. Zig-zag

12. Left Needle Position
13. Middle Needle Position

18. Right Needle Position

Stitch Width Dial & Stitch Length Dial

Function of stitch width dial
The maximum zigzag stitch width for zigzag stitching is 6mm; however, the width can be reduced on any patterns. The width increases as you move zigzag dial from "0" - "6".

Function of stitch length dial while zig-zag stitching
Set the Pattern Selector Dial to zig-zag.
The density of zig-zag stitches increase as the setting of stitch length dial approaches "0".
Standard zigzag stitches are usually achieved at "3" or below.
Dense zig-zag stitches are called satin stitches.

Function of stitch length dial for when straight stitching
For straight stitch sewing, turn the Pattern Selector Dial to the straight stitch setting. Turn the Stitch Length Dial, and the length of the individual stitches will decrease as the dial approached "0". The length of the individual stitches will increase as the dial approaches "4". 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.

Sewing Straight Stitch

To begin sewing, set the machine for straight stitch.

Place the fabric under the presser foot with the fabric edge lined up with the desired seam guide line on the needle plate.

Lower the presser foot lifter, and then step on the foot controller to start sewing.

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.

Removing the Work

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

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.

Choosing Stretch Stitch Patterns

The stretch stitch patterns are indicated with blue and red colors on the pattern selector dial. To select these stitches, turn the pattern selector dial to the desired pattern. Then, turn the stitch length dial to the indicator marked "S1" or "S2". Though there are several stretch patterns, here are two examples:

Straight Stretch Stitch

Set the pattern selector dial to "".
Set the stitch width dial to "1".
Used to add triple reinforcement to stretch and hardwearing seams.
The machine sews two stitches forward and one stitch backwards.

Ric Rac

Set the pattern selector dial to "".
Set the stitch length dial to "S1" or "S2".
Adjust the stitch width dial to between "3" and "6".
Ric rac stitch is suitable for firm fabrics like denim, corduroy, poplin, duck, etc.

Blind Hem

For hems on curtains, trousers, skirts, etc.
Blind hem for stretch fabrics.
Blind hem for firm fabrics.
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. Set the Stitch Width Dial at a setting appropriate for the weight/type of fabric being sewn, within the range shown in the diagram on the right of the page. 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.

Sew 1-step Buttonholes

Buttonhole sewing is a simple process that provides reliable results. However, it is strongly suggested to always make a practice buttonhole on a sample of your fabric and stabilizer.

Making a Buttonhole

1. Using tailor's chalk, mark the position of the buttonhole on the fabric.
2. Attach the buttonhole foot and set the Pattern Selector Dial to "". Set stitch length dial to "". Set the stitch width at "6". The width however may need to be adjusted according to the project. Sew a test first to determine this.
3. Lower the presser foot aligning the marks on foot with the marks on the fabric (A). (The front bar tack will be sewn first.) (Align the mark on the fabric (a) with the mark on the foot (b).)
4. Open the button plate and insert the button (B).
5. Lower the buttonhole lever and gently push it back (C).
6. While lightly holding the upper thread, start the machine.
7. Buttonhole stitching is done in the order (D).
8. Stop the machine when the buttonhole cycle has completed.

Making a Buttonhole on Stretch Fabrics (E)
When sewing buttonholes on stretch fabric, hook heavy thread or cord under the buttonhole foot. When the buttonhole is sewn the legs will overcast the cord.

1. Mark the position of the buttonhole on the fabric with the tailor's chalk, attach the buttonhole foot, and set the pattern selector dial to "". Set stitch length dial to "".
2. Hook the heavy thread onto the back end of the buttonhole foot, then bring the two heavy thread ends to the front of the foot, insert them into the grooves and temporarily tie them there.
3. Lower the presser foot and start sewing.
   *Set the stitch width to match the diameter of the gimp thread.
4. Once sewing is completed, gently pull the heavy thread to remove any slack, then trim off the excess.

Left and Right Side Balance for Buttonhole

Stitch density on right and left sides of buttonhole can be adjusted by buttonhole balance control dial.
This dial should usually be in a neutral position (between "+" and "–")
If the stitches on the left side of buttonhole are too close together, turn the dial to the left (+). * Turning dial to the left opens left side. If the stitches on the left side of the buttonhole are too open, turn the dial to the right (–).
* Turning dial to right closes left side.

Sewing on Buttons

Move the drop feed control to right side to lower the feed dogs. (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, then set the width to number "3" - "6". Turn the handwheel to check that the needle goes cleanly into the left and right holes of the button. Adjust the stitch width, as needed, according to the distance between the 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. For buttons with 4 holes, sew through the front two holes first, push the work forward and then sew through the back two holes.
