GETTING READY TO SEW

Powering Your Machine

Connect the machine to a power source as illustrated. This machine is equipped with a polarized plug which must be used with the appropriate polarized outlet. (a and b)

Unplug power cord when machine is not in use.

Foot Control
The foot control regulates the sewing speed. When foot control is disconnected, the machine will not operate.

Sewing Light
Press main switch (A) to " I " for power and light.

For machine with a polarized plug (one blade is wider than the other). To reduce the risk of electric shock, this plug is intended to fit in a polarized outlet only one way. If it does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician to install the proper outlet. Do not modify the plug in any way.

Your Singer machine is adjusted to provide the best stitch results at normal room temperature. Extreme hot and cold temperatures can affect the sewing results.

Winding the Bobbin

This machine uses SINGER^® Class 15 transparent bobbins. Use only this style of bobbin when purchasing additional bobbins for your machine. Do not substitute with metal bobbins.

1. Place thread spool and corresponding size spool holder onto spool pin. Spool holder should be large enough to cover the end of the thread spool so thread unreels smoothly. For smaller, narrower spools, use the small spool cap, which can be found in the removable storage compartment.
   
2. (A) Snap thread into guide at top of machine. (B) Place thread snuggly around bobbin winding tension disk to ensure that thread winds onto bobbin smoothly and consistently. (C) Thread bobbin as shown, then place it onto the bobbin winding spindle.
   
3. Check that bobbin is pushed down firmly (A). If it is not, the thread could begin winding under the bobbin. Push the bobbin and spindle firmly to the right (B).
   
4. Hold the thread end to get ready to wind. Step on the foot controller gently as you hold the thread end. Allow it to wind a few revolutions slowly, then remove your foot from the foot control to stop.
   
5. Trim the thread end close to the top of the bobbin, then resume winding by stepping on the foot controller.
   
6. The bobbin will stop winding when it is full. Lift your foot off the foot control. Push the bobbin to the left (A), then trim the thread and remove the bobbin from the spindle (B).
   

Inserting the Bobbin

Turn power switch off before inserting or removing the bobbin.

1. When inserting or removing the bobbin, the needle and presser foot must be fully raised.
   
2. Remove the bobbin cover plate and bobbin.
   
3. Insert the bobbin in the bobbin case with the thread running in a counterclockwise direction (arrow).
   
4. Pull the thread through the slit (A).
   
5. With a finger held gently on top of the bobbin, place thread into guides as shown.
   
6. To cut off excess thread pull it toward you to cut it with the cutter at point (B). Replace the bobbin cover plate.
   

Threading the Upper Thread

For safety, turn off the power before threading the machine.

1. Start by turning the handwheel (A) toward you to raise the needle (B) and the thread take up lever (C). You should be able to see the take up lever.
   
2. Raise the presser foot lifter. This is necessary in order for the machine to be threaded correctly.
   
3. Place the thread spool and spool cap onto the spool holder.
   
4. Draw thread from the spool through the upper thread guide at the top of the machine. Hold the thread with both hands and pull it into the pretension guide.
   
5. (A) Bring the thread down the right channel, around the U-turn, and up the left channel. (B) At the top of the left channel, hook the thread from back to front through the slotted eye of the thread take-up lever. If the thread does not pass into the eye of the take-up lever, the machine will jam. After threading the take-up lever, bring the thread downward again. (C) Pass the thread behind the metal thread guide and then down to the needle.
   
6. To thread the needle manually, thread it from front to back. Pull about 6-8 inches of thread to the back beyond the needle eye.
   

Drawing Up the Bobbin Thread

For safety, turn off the power before threading the machine.

1. Hold the upper thread tail with the left hand (A). Turn the handwheel toward you (B), first lowering (C) and then raising the needle (D).
   
2. As you turn the handwheel, gently pull the upper thread, which will bring a loop of the bobbin thread up through the hole of the needle plate (E). Pull the loop to bring the bobbin thread end up through the opening in the needle plate. If a loop doesn't pull up, turn the handwheel toward you one more time. If it still doesn't come up, check that the bobbin thread is not trapped by the bobbin cover.
   
3. Bring both threads under the presser foot and toward the back of the machine.
   

START SEWING

Before You Start Sewing

Now that your machine is threaded, we will show how to set up the machine for basic sewing techniques such as: sewing a straight stitch, sewing a decorative stitch, sewing a stretch stitch, sewing a buttonhole and sewing a button. With each technique, you have the opportunity to sew along.

For more information about the various stitches on your machine and how to use them, refer to the Stitch Reference Guide by visiting www.singer.com.

Here are a few other tips that you may find helpful before you begin:

• When unpacking the machine, you may have noticed some small traces of oil around the needle plate or presser foot area. If so, wipe off any excess oil with a soft, dry cloth before you start sewing. It is also recommended that you sew on a piece of scrap fabric to remove excess oil.
• The foot control is used to control the speed of your sewing. When you press down on the foot control, the machine will sew. The greater the pressure you place on the foot control, the faster the machine will sew. When you take your foot off the foot control, the machine will stop.
• Needles are an important part of sewing. Using old, damaged or incorrect needles for your projects can affect sewing results. For information about which needle to use for your project, refer to the Stitch Reference Guide at www.singerco.com.
• Depending on the sewing technique you want to do, it may be necessary to change to a different presser foot.
• Review the information about Stitch Formation. This will help you understand what the stitching should look like when you sew.
• Use the thread cutter on the machine to trim thread tails when finished sewing. This is helpful because thread tails are left long enough so that the needle does not become unthreaded when you start sewing again.

Stitch Formation

1. How Stitches Form
   Stitches are formed when the upper thread and the bobbin thread interlock between the fabric layers. Stitching is well balanced when the needle thread appears on the top and the bobbin thread appears on the bottom.
   
2. Thread Tension Dial
   The Thread Tension Dial has a range of settings between 0 and 9. Most of your sewing will be done with your Thread Tension Dial set between 3 and 5. It can be adjusted to a higher number for more tension on the upper thread, if the upper thread seems too loose. It can be adjusted to a lower number for less tension on the upper thread, if the bobbin thread seems to be showing on the top side of the fabric.
   
   Adjusting Tension
   Thread tension can also be adjusted for various sewing techniques. For basting (see Appendix), you can loosen it to a lower number so that the stitches can easily be removed. For gathering, you can turn it to a higher number.
   
3. When you sew, if you see large loops on the underside of the fabric, this is actually an indication that the upper thread was not threaded correctly, as it has no tension controlling it. For information on how to correct this, see the Troubleshooting and Maintenance section of this manual.
   

Stitch Selector Dial

The Stitch Selector Dial is used to select the stitch you want to sew. The dial can be turned to the left or to the right.

For Sewing the Grey Stitch Patterns:

1. Turn the Stitch Selector Dial until it clicks in place under the dot directly above the dial on the machine.
   
2. Set the Stitch Length Dial according to the length you want. It can be set anywhere between 0.5 and 4, with 4 being the longest setting.
   

For Sewing the Blue or Red Stitch Patterns:

1. Turn the Stitch Selector Dial until it clicks in place under the dot directly above the dial on the machine.
   
2. Set the Stitch Length Dial so that the S1 or S2 is lined up with the dot above this dial. This dial must be set at the S1 marking for the blue stitches or the S2 marking for the red stitches, or the stitch pattern will not sew.
   

For examples of stitch patterns and further instruction, see the Stitch Reference Guide at www.singerco.com.

Sewing a Straight Stitch

A straight stitch is used for sewing seams and topstitching.

HOW TO:

1. Set the machine for Straight Stitch by setting the Stitch Selector Dial to straight stitch.
2. The Stitch Length Dial control can be set at the stitch length that you desire.

SEW ALONG:

1. Set the Stitch Selector Dial so that the straight stitch symbols are directly below the dot.
   
2. Set the Stitch Length Dial control so that the number 2 is directly below the dot on the machine. This is an average stitch length setting for regular sewing.
   
3. Place the fabric under the All-Purpose Foot with the right-hand edge of the fabric lined up with the desired seam guide line on the right side of the needle plate. Lower the presser foot, then step on the foot control to begin sewing. Always make sure that the presser foot is lowered before you begin to sew. If you fail to do so, the machine will jam as you begin to sew. Start your seam by sewing 2 to 3 stitches. Press the reverse lever to sew backwards 2 to 3 stitches, which will lock the end of the seam so the stitches don't come undone. Release the reverse lever to sew forward again. Continue sewing the length of the seam. Press the reverse lever at the end of the seam and sew backwards 2 to 3 stitches. Release the reverse lever to sew forward again to finish.
   

Use a slightly shorter stitch length for lightweight fabrics, finer threads and needles. Use a longer stitch length such as 3 or 4 for heavy weight fabrics.

It may be helpful to gently hold the thread tails with your left hand for the first few stitches, as this will help guide the fabric under the foot as you begin to sew.

Sewing a Decorative Stitch

A decorative stitch is used for embellishing and adding flair to your sewing projects. (Go to www.singerco.com to view other decorative stitches that can be used).

HOW TO:

1. Set the machine to the desired stitch by setting the Stitch Selector Dial to one of the decorative stitches.
2. Set the Stitch Length Dial between 0.5 and 3.

SEW ALONG: Scallop Stitch

1. Set the Stitch Selector Dial, so that the Scallop Stitch setting is directly below the dot.
   
2. Set the Stitch Length Dial control so that number 1 is directly below the dot on the machine.
   
3. Place the fabric under the All-Purpose Foot with the right-hand edge of the fabric lined up with the desired seam guide line on the right side of the needle plate. Lower the presser foot, then step on the foot control to begin sewing. Sew 2 to 3 stitches and then backstitch to reinforce the seam.
   

Use a stabilizer (see Appendix) on the underside of the fabric if there is gathering or puckering as you sew. Decorative stitching can be used almost anywhere on your project!

It may be helpful to decrease the upper tension by 1 or 2 numbers when sewing decorative stitches. This will help prevent the bobbin thread from possibly showing on the top when sewing denser stitches.

Sewing a Stretch Stitch

A stretch stitch is used for knit fabrics. This type of seam will stretch with the fabric. (Go to www.singerco.com to view other stretch stitches that can be used).

HOW TO:

1. Set the machine to the desired stitch by setting the Stitch Selector Dial to one of the stretch stitch settings.
2. Set the Stitch Length Dial to the Stretch S1 setting for the blue stitches or S2 for the red stitches.

SEW ALONG: Overedge Stitch

1. Set the Stitch Selector Dial, so that the Overedge stitch setting is directly below the dot.
   
2. Set the Stitch Length Dial control so that the S1 setting is below the dot.
   
3. Place the fabric under the All-Purpose Foot with the right-hand edge of the fabric lined up with the desired seam guide line on the right side of the needle plate. Lower the presser foot, then step on the foot control to begin sewing.
   

Sewing a 1-Step Buttonhole

This machine has a built-in buttonhole feature, allowing you to sew buttonholes in one easy step. The Stitch Selector Dial shows the buttonhole settings in grey.

HOW TO:

1. Set the machine to the desired stitch by setting the Stitch Selector Dial to the buttonhole stitch.
2. Set the Stitch Length Dial within the buttonhole range.

SEW ALONG: Buttonhole Stitch

1. Place the button at the back of the buttonhole foot. Mark position and length of buttonhole on the fabric.
   
2. Remove the All-Purpose Foot and attach the Buttonhole Foot. Pass upper thread through the hole of the foot and bring thread to the left.
3. Set the Stitch Selector Dial so that the buttonhole symbol is directly below the dot.
4. Set the Stitch Length Dial control so that the buttonhole range is directly below the dot.
   
5. Place the fabric under the foot so that the center line mark on your fabric is aligned with the center of the buttonhole foot and that the cross line mark on the fabric aligns with the center hole of the Buttonhole Foot. Lower the presser foot.
6. Pull the buttonhole lever all the way down and then carefully push it back. The buttonhole lever must sit in front of the notch located on the left of the buttonhole foot.
7. Hold upper thread slightly and start to sew until the buttonhole is completed.
   
8. Return the buttonhole lever to its original position once all buttonholes are completed.

Use a stabilizer to support the stitches.

Slightly reducing your upper tension by 1 or 2 numbers will improve results.

Always test sew on a scrap piece of your fabric.

Sewing a Button

This machine includes a Button Sewing Foot, allowing you to attach buttons to your projects easily and quickly.

HOW TO:

1. Set the machine to Straight Stitch by turning the Stitch Selector Dial to the Straight Stitch Symbol.
2. Set the Stitch Length Dial to 0 to begin.

SEW ALONG: Attaching a Button

1. Attach the Darning Plate to the needle plate directly below the presser foot. To do this line up the prongs on the underside of the Darning Plate with the holes in the needle plate. Push down to snap it in place.
   
2. Remove the All-Purpose Foot and attach the Button Sewing Foot.
   
3. Set the Stitch Length Dial control so that 0 is directly below the dot.
   
4. Set the Stitch Selector Dial so that the Straight Stitch setting is directly below the dot.
   
5. Place the button on the fabric, then line up the button directly under the front of the Button Foot so the 2 holes of the button appear in front of the foot. Turn the hand wheel towards you to make sure the needle clears the hole on the left. Step on the foot control and sew 3 to 4 securing stitches. Raise the needle out of the fabric and the button.
   
6. Set the Stitch Selector Dial so that the Zig Zag setting is directly below the dot. Adjust the dial until the needle moves from the left hole into the right hole of the button without interference. To test the movement of the needle turn the handwheel manually towards you several times to make sure the needle does not hit the button. Sew 10 to 12 stitches.
   
7. Set the Stitch Selector Dial so that the Straight Stitch setting is directly below the dot.
   
8. Sew 3 to 4 stitches to secure the stitching.

Remove the Darning Plate when finished.

Inserting and Changing Needles

Turn the machine off before changing the needle.

Change the needle regularly, especially if it is showing signs of wear resulting in sewing problems. Needles can show signs of wear when you see snags in the fabric or hear a slight popping sound as you are sewing. If the needle becomes bent (A), the point becomes damaged (B) or the needle becomes dull (C), you should replace it with a new needle and discard the old one.

Generally, the needle should be replaced after every 4 projects or approximately every 16 hours of sewing time.

It is also important to use the right needle for the fabric you are sewing. (Go to www.singerco.com to view the Stitch Reference Guide) For best results, use SINGER^® branded needles in your SINGER^®sewing machine.

Loosen the needle clamp screw (A) by turning the screw toward you. Remove and discard the old needle. Insert the new needle, making sure that the flat side of the top part of the needle is facing the back of the machine (B). Insert the new needle as far up as it will go (C and D). Tighten the needle clamp screw (A) securely by turning it toward the back.

Changing the Presser Foot

For safety, turn off the power before changing the presser foot.

Before changing the presser foot, raise the presser foot lifter. The presser foot holder (b) is attached to the presser bar (a). The presser foot (e) has a presser foot pin (d) that connects to the presser foot holder, sometimes called a shank (b). The shank has a groove (c) on its front, which connects it to the presser foot.

To remove a presser foot from the shank, pull the presser foot (e) toward you to disengage from the groove (c). The foot will release. To attach a presser foot, slide the pin (d) of the presser foot (e) into the groove (c) on the shank. The foot will snap on.

Some optional presser feet require you to remove the shank from the machine. To remove the shank from the machine (see above) loosen and remove the screw that holds the presser foot onto the presser bar (a), then remove the shank (b). To replace the shank, set the shank onto the presser bar, then replace the screw.

This machine has a low shank with snap-on presser feet. When shopping for optional presser feet and attachments for your machine, look for low-shank, snap-on style.

Troubleshooting

1. Thread Loops on Underside of Fabric
2. Bobbin Thread Showing on Top of Fabric
3. Upper Thread Breaking
4. Thread is Shredding
5. Thread Bunching at Beginning
6. Skipping Stitches
7. Bobbin Winding Difficulties
8. Bobbin Thread Breaking
9. Needles Breaking
10. Stitches Distorted
11. Fabric Puckers
12. Fabric Is "Tunneling" Under Stitches
13. Machine Not Feeding Fabric
14. Loud Noise When Sewing
15. Machine Will Not Run

THREAD LOOPS ON UNDERSIDE OF FABRIC

Possible Cause: Thread looping on the underside of the fabric is always an indication that the upper thread is not correctly threaded. This happens when the upper thread is not correctly placed in the tension mechanism and has not been threaded through the take up lever.

Solution: Rethread machine, making sure to first raise the presser foot lifter before starting to thread, so thread can be properly seated in the tension mechanism and take up lever.

To know if you have rethreaded the machine correctly, try this simple test:

• Raise the presser foot lifter and thread the top of the machine.
• Thread the needle, but don't put the thread under the presser foot yet. As you pull the upper thread to the left, it should pull freely.
• Put the presser foot lifter down. As you pull the upper thread to the left, you should feel resistance. This means you are threaded correctly.
• Put the thread under the presser foot, and then draw up the bobbin thread. Slip both thread tails under the presser foot towards the back. Lower presser foot and begin sewing.

If you put the presser foot lifter down, but the thread still pulls freely (you feel no difference whether the presser foot is up or down), this means you have threaded incorrectly. Remove the upper thread and rethread the machine.

BOBBIN THREAD SHOWING ON TOP OF FABRIC

Possible Cause: Top thread tension too tight.
Solution: Reduce upper thread tension.

Possible Cause: Thread path is obstructed, putting extra tension on top thread.
Solution: Check that the top thread path is not obstructed and thread is moving freely through the thread path.

Possible Cause: Bobbin thread not in bobbin case tension.
Solution: Rethread bobbin.

UPPER THREAD BREAKING

Possible Cause: Thread path obstructed.
Solution: Check if thread is caught on thread spool (rough spots on the spool itself) or behind spool pin or spool cap (if the thread has fallen behind the spool cap and therefore cannot feed freely through the machine path).

Possible Cause: Machine is not threaded correctly.
Solution: Remove upper thread completely, raise presser foot lifter, rethread machine making sure thread is in take-up lever (raise take up lever to its highest position by turning hand wheel toward you.

Possible Cause: Upper tension too tight.
Solution: Reduce upper thread tension.

THREAD IS SHREDDING

Possible Cause: Thread is old or poor quality.
Solution: Rethread the top of the machine and bobbin with good quality thread.

Possible Cause: The needle is either worn or old, or it is the wrong style or size for the thread being used. Though it may seem that the machine is shredding the thread, it is usually the needle causing this. If the needle is old or worn out, or if the needle is too small for the thickness of thread, the eye of the needle can cause the thread to shred.
Solution: Change to a fresh needle in the correct size for the thickness/weight of thread being used.

THREAD BUNCHING AT BEGINNING

Possible Cause: Top & bobbin threads have not been properly placed underneath presser foot before starting to sew.
Solution: Ensure that both the top thread and the bobbin thread are under the presser foot and toward the back before starting to sew.

Possible Cause: Sewing was started with no fabric under the presser foot.
Solution: Place fabric under foot, making sure that needle comes down into fabric; lightly hold both thread tails for first few stitches.

SKIPPING STITCHES

Possible Cause: Needle inserted incorrectly.
Solution: Check that flat side of needle top is toward back of machine and needle is up as far as it can go, then tighten needle clamp screw.

Possible Cause: Wrong needle for fabric sewn.
Solution: Use correct style & size of needle for fabric. (Go to www.singerco.com to view the Stitch Reference Guide)

Possible Cause: Bent, dull or damaged needle.
Solution: Discard needle and insert new needle.

BOBBIN WINDING DIFFICULTIES

Possible Cause: Bobbin thread loosely wound on bobbin.
Solution: Rewind bobbin, making sure that the thread is placed snuggly in the bobbin winding tension disk.

Possible Cause: Bobbin winding spindle not fully engaged, therefore bobbin not winding.
Solution: Check that the bobbin winding spindle has been fully engaged before starting to wind.

Possible Cause: Bobbin is winding sloppily because thread end not held at beginning of winding process.
Solution: Before starting to wind, hold the thread tail (coming out of the bobbin) securely, allow the bobbin to partially fill, then stop to trim the thread tail close to the bobbin.

BOBBIN THREAD BREAKING

Possible Cause: Bobbin threaded incorrectly.
Solution: Check that bobbin is placed correctly in the bobbin case.

Possible Cause: Bobbin wound too full or unevenly.
Solution: Bobbin thread may not have been correctly placed into bobbin winding tension disk during the bobbin winding process.

Possible Cause: Dirt or lint in bobbin case.
Solution: Clean bobbin case.

Possible Cause: Wrong bobbins being used.
Solution: Use SINGER^® bobbins that are the same style as those that come with the machine – don't substitute. Your machine comes with SINGER^® Class 15 transparent bobbins.

NEEDLES BREAKING

Maintenance

Cleaning the Feed Teeth and Hook Area

Before cleaning the machine, disconnect the power supply by removing the plug from the electrical outlet. Turn the hand wheel to raise the needle to its highest position. Raise the presser foot lifter.

To ensure the best possible operation of your machine, it is necessary to keep the essential parts clean. For daily machine use, it is recommended that you clean the machine weekly.

1. Remove the bobbin cover and then the presser foot by pressing down on both sides of the presser foot. Removing the presser foot will provide better access to the needle plate and bobbin case area.
2. Turn the handwheel towards you until the needle is at the highest position. (The take-up lever should be visible over the top of the machine).
3. Remove the 2 screws in the needle plate using the L-screwdriver provided with your machine. Remove the needle plate.
4. Remove the bobbin from the bobbin case.
5. Take a hold of the bobbin case with your thumb and index finger at about 7 o'clock. Push it lightly to the right as you lift, the bobbin case will easily slip out of the hook race area.
6. Using the small brush that was provided with your machine remove lint and fluff from the hook race area, as well as the feed teeth area.
7. Your machine has been pre-lubricated at the factory; as a result oiling the bobbin case area is not necessary.
8. To reinsert the bobbin case, make sure the needle is at the highest position. (The take-up lever should be visible over the top of the machine).
9. Take a hold of the bobbin case with your thumb and index finger at 6 o'clock directly over the left screw at the center front of the bobbin case.
10. Guide the forked end of the bobbin case under the feed teeth and then move the bobbin case from right to left, until it is seated correctly in the hook race.
11. To ensure that the bobbin case is in the correct position, turn the handwheel towards you; the hook race should turn freely in a counter-clockwise direction.
12. Make sure the needle is again at the highest position. Reposition the needle plate over the feed dogs and secure in place using the 2 screws that you removed earlier.
13. Attach presser foot, insert bobbin and replace bobbin cover. You are now ready to sew.

Glossary of Key Sewing Terms

Backstitch
Backstitching is most commonly used at the beginning and ending of seams to lock the stitching so it does not come undone. Start sewing the beginning of the seam about 3-4 stitches, then sew in reverse for 3-4 stitches. Start sewing forward again and continue sewing the seam to the end, then sew in reverse 3-4 stitches, then forward again to finish.

Basting
Basting is temporary stitching, sewn using a long straight stitch and reduced tension. This temporary stitching holds fabrics together, but is intended to be removed. For example, basting the side seams of a skirt to check the fit, then the final seam is sewn and the basting stitch is removed.

Free Arm
In order to sew small, tubular projects such as a pant leg, sleeve cuff, etc, you will need to take the removable storage compartment off the machine, giving access to the free arm.

Interfacing
Interfacing is specially designed material, sewn between fabrics, used to provide additional structure to parts of a garment, for example, cuffs, collars, plackets, etc. It can be used for buttonholes to help keep the fabric stable while sewing.
