Caution:

Always close looper cover before operating machine.

15. HOW TO ADJUST THE PRESSER FOOT PRESSURE

- The presser foot pressure of this machine is preadjusted at the factory to suit the sewing of medium weight fabrics.

- Most of the materials do not require adjustment of presser foot pressure however, there are some instances where adjustment is necessary when sewing lightweight and heavyweight fabrics.

- In such case, insert screwdriver through access hole (A) in top cover and into slot (B) in pressure regulating screw and turn regulating screw as required.

Note: Turn regulating screw counterclockwise until it stops against the top cover. Then turn screw clockwise 6 turns which will be the standard presser bar pressure.

• For lightweight fabric ... Decrease the pressure

• For heavyweight fabric ... Increase the pressure

16. DIFFERENTIAL FEED

• Differential feed is a system which "stretches" or "gathers" the fabric, when amount of feed of front feed dog in relation to the rear feed dog is changed.
• The differential feed ratio ranges from 1:0.7 \~ 1:2.0. Adjustment is made by means of the differential feed adjusting lever pictured below.
• Use of differential feed is very effective in overedging stretch fabrics and fabrics cut on the bias.
• Graduation "1.0" is differential feed adjusting lever setting for ratio 1:1.

Gathered Overedge

- Gathered overedge is most suited for shirring sleeves, yokes, front and back bodices, skirt hems, etc. in stretch fabrics such as knits and jersey before assembling into garment.

To set the differential feed adjusting lever

• Set differential feed adjusting lever knob below graduation "1.0". Setting of adjusting lever knob depends on material being sewn as well as the amount of gather therefore set knob to suit the fabric and test sew before sewing your garment.
• When feed regulating dial is set at "3" or over, the amount of feed of the main feed dog will change to "3" automatically when adjusting lever knob is set to 2.0.

Note: For normal overedge stitching, set differential feed adjusting lever knob to graduation "1.0".

Stretch Overedge

- Stretch overedge is ideal for sewing decorative collars, sleeves, skirt hems, etc. on loosely knit and woven fabrics.

To set the differential feed adjusting lever

- Set differential feed adjusting lever knob above graduation "1.0".

- To sew a seam, apply gentle tension to the fabric by holding the seam lightly in front and back of the presser foot.

Note: * If amount of "stretch" is not correctly set in relation to the fabric being sewn, the fabric is apt to shift away from the needle resulting in improperly sewn overedge seam. In such case, reset differential feed adjusting lever closer to the center mark. * Be sure to reset the differential feed adjusting lever to graduation "1.0" for normal overedge stitching.

20. STANDARD OVEREDGE AND ROLLED HEM STITCHING

To Sew Standard Overedge

- Set seam width finger knob to S to move seam width finger to projected position.

Note: Be sure to push seam width finger knob as far as it will go in the direction of setting S.

To Sew Rolled Hem

- Set seam width finger knob to R to retract the seam width finger.

Note: Be sure to push seam width finger knob as far as it will go in the direction of setting R.

21. CHAINING OFF AND TEST SEWING

- When the machine is completely threaded, bring all of the threads over the throat plate and slightly to the left under the presser foot.

- Hold the threads and apply a slight tension.

- Turn the hand wheel toward you 2 or 3 complete turns to start the thread chain.

- Lower presser foot.

- Continue holding the chain and press on the foot controller until the chain is 5 \~ 7.5cm (2 \~ 3 inches) in length.

- Place fabric under the front of the presser foot and sew a test sample.

Note: Do not pull on the fabric while sewing as this may deflect the needle, causing it to break.

22. Starting and Ending Seams

To Start a Seam

- To start a seam on most fabrics, first bring the thread tail under the presser foot and then to the left of the machine.

- Hold the thread tail and step on the foot controller to begin sewing.

Sew until you have created a 3" (7.5 cm) chain.

- Place the fabric on the feed dogs in front of the foot. Start sewing.

Note: * For heavy or thick fabrics, it is recommended to use SINGER needles #2022 size 100/16.

* Heavy or thick fabrics may be more difficult to feed than others. In these cases, start by cutting a notch at the beginning of the seam about 1" (2.5 cm) down from the top of the fabric, and along the seam line.

* Lift the presser foot and raise the needles. Place the notch so that the top edge of the fabric is in front of the needles, with the cut edge lined up next to the blade.

* Lower the presser foot and sew.

To End a Seam

- To end a seam, continue sewing past the end of the fabric until the thread chain forms.

- Cut the thread, leaving at least 3" (7.5 cm) at the end of the fabric.

24. HOW TO SEW A ROLLED HEM

• This machine can sew four types of rolled hems.
- Rolled hemming is done by rolling and overedging the fabric edge.
- Light weight fabrics such as lawn, voil, organdy, crepe, etc, perform the best.
- Rolled hemming is not suited for heavy or stiff fabrics.

Machine Set Up

• Remove the left needle.
• Move seam width finger knob to setting R. (See page 28)
• Align left face of seam width finger support plate with R mark on throat plate by turning seam width finger knob, as required.
• Set stitch length dial to "F\~2" and a fine seam will be sewn.
• Needle: Singer Needle #2022 size 80/11 or 90/14
• Thread: A variety of thread combinations can be used for rolled hemming.

Note: For a beautiful two-thread rolled hem thread the upper looper with wooly nylon and the needle with lightweight regular thread.

Additional Information About Rolled Hemming

- Hold the thread chain when you begin sewing to keep it from curling into the seam.

• Place a slight tension on the material in the sewing direction and a finer seam finish can be obtained.
• The minimum overedge stitch width that can be obtained for rolled hemming is approximately 1.5mm (1/16 inch) since the cutting width cannot be set below 3.5mm (9/64 inch).

To Secure the Rolled Hem Thread Chain

- Apply a small drop of liquid seam sealant to the end of the seam. Allow to dry, then cut the chain close to the stitches.

Note: Test the liquid seam sealant for color fastness before use.

25. STITCH VARIATIONS AND SEWING TECHNIQUES

How to Sew a Flatlock Decorative Seam

• A flatlock stitch is achieved by adjusting the tension of the 3-thread overlock stitch, sewing the seam and pulling the fabric apart to flatten the seam.
• The flatlock stitch can be used as a construction and decorative stitch or for ornamentation only.

(1) Machine Set Up

• Remove the left or right needle.
• Begin with the machine threaded and tension balanced for the 3-thread overlock stitch (page 29).
• Loosen the needle thread tension (green or bule) generously.
• Loosen the upper looper thread tension (orange) slightly.
• Tighten the lower looper thread tension (yellow) generously.

(2) Flatlocking a Seam

• Place the fabric wrong sides together to sew a decorative stitch on the right side of the garment.
• Sew the seam, trimming the excess fabric.

- The needle thread (green or blue) will form a V on the underside of the fabric.

- The lower looper thread will pull into a straight line at the fabric edge.

- Pull on opposite sides of the seam to pull the stitches flat.

(3) Decorative Flatlocking

- Place the movable upper knife in the nonworking position (page 25). The fabric is not trimmed or this stitch.

- Fold fabric wrong sides together.

- Position the fabric so the seam is sewn with par of the stitch extending off the fabric.

- Pull on opposite sides of the stitch to flatten.

(4) Additional Information About Flatlocking

• The tensions must be correctly adjusted for the fabric to pull flat.
• The upper looper thread is the prominent thread in the flatlock stitch. Place a decorative thread in the upper looper and inconspicuous threads in the lower looper and needle.
• For a ladder stitch, sew seam with right sides together. The needle thread will be the prominent thread that creates the ladder (A).

How to Sew an Overlock Blind Hem

• The excess fabric is trimmed and the hem is sewn and the raw edges are overlocked in one operation.
• The overlock blind hem is best suited for sewing knit wear. It provides a durable finish that is almost invisible.
• Remove the left needle and adjust machine for a narrow 3-thread overlock stitch.
  Note: The three-thread flatlock stitch can also be used.
• Set the stitch length dial at 4.
• Fold the hem to the wrong side of the fabric, then back to the right side with 6mm (1/4") beyond the fold.
• Stitch on the extended hem edge, allowing the machine needle to barely catch the edge of the fold.

How to Sew Pin Tucks

• Sew decorative pin tucks on the fabric before cutting out the garment.
• Remove the left needle and adjust machine for a narrow 3-thread overlock stitch.

Note: The rolled hem stitch can also be used for this technique.

• Place the movable upper knife in the nonworking position (page 25).
• mark the fabric with the desired number of pin tucks using a water soluble fabric marker.

Fold the fabric with the wrong sides together and sew.

Press the pin tucks in the same direction.

Cutting line

Turning Square Corners

(1) Outside Corner

Cut out approximately 2 cm (51/64 inch) from the corner, in line with the overedge seam edge.

Sew one stitch beyond point (A) and stop.

Raise needle and presser foot.

Pull the fabric to the rear of the machine just enough to release the thread caught on the finger of the throat plate.

Note: Presser foot has been removed to show detail.

Turn the fabric and lower the presser foot so that the knife is positioned in line with the cut edge.

Pull slack threads up, then start to sew.

Cutting line

(2) Inside Corner

Cut fabric at seam edge.

Cut Slit

- Place the movable upper knife in nonworking position (page 25).

- Stitch on cut edge of fabric.

- Stop sewing before you reach the corner and fold the fabric to the left to straighten the corner.

- Continue to sew slowly holding the fabric edge in a straight line moving the fold as you sew.

Pin Placement

- Insert pins to the left of the presser foot. The pins will be easy to remove and are away from the cutting action of the knives.

Caution:

Sewing over pins will damage and/or destroy the cutting edge of the knives.

Securing the Thread Chain

- Thread a large eye, hand sewing needle (such as a tapestry needle) with the thread chain.

- Insert the needle into the end of the seam to secure thread.

Note: To secure a rolled hem thread chain, see page 39.

How to Reinforce a Seam

• Inserting twill tape while overedge sewing will stabilize the seam.
• Insert the tape through the hole in the front of the foot.
• Position the tape under the foot to the back of the machine and sew the garment seam.

• The tape is attached as the seam is sewn.

Braiding by Chaining Off

• Place the movable upper knife in nonworking position.
• Insert filler cord such as yarn or twill tape through the hole in the front of the foot.
• Position the filler cord under the foot and chain off the desired length.
• Chained off braids can be used individually or woven into 3 or 4 ply braids.

26. MACHINE MAINTENANCE

An overlock requires more maintenance than a conventional machine mainly due to two reasons.

1) A lot of lint is produced due to the cutting action of the knives.
2) An overlock runs at a very high speed and needs to be oiled frequently to lubricate the internal working parts.

Cleaning the Machine

Danger:

Before cleaning your machine, disconnect power line plug from the wall receptacle.

- Clean the lint from the looper and knife area often with a dry lint brush.

Note: Lint brush is an optional part.

Oiling the Machine

Danger:

Before lubricating your machine, disconnect power line plug from the wall receptacle.

- The oiling points shown in the diagram, should be oiled periodically.

Note: Use sewing machine oil. Do not use any other oil or damage could result.

How to Replace the Stationary Knife

Danger:

Before replacing the stationary knife, disconnect power line plug from the wall receptacle.

- The stationary knife should be changed when it becomes dull.

- The stationary knife can be replaced according to the directions provided, however if there are any difficulties experienced, consult your Singer representative to make the adjustments.

- Be sure that the power line plug is disconnected from the electric source.

- Open the looper cover and set the movable upper knife 1 in the nonworking position (page 25).

- Loosen the stationary knife set screw 2 and remove the stationary knife 3.

- Place a new stationary knife in the groove of the stationary knife holder.

- Tighten stationary knife set screw 2.

- Return the movable upper knife 1 to its working position.
