Winding the Bobbin
This machine uses 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 rmly (A).
If it is not, the thread could begin winding
under the bobbin. Push the bobbin and spindle
rmly to the right (B).

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 two pre-
tension guides at the top of the machine (see
page 8). Hold the thread with both hands and
pull it into each of the guides.
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, slip 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 when you start to sew. After threading
the take-up lever, bring the thread downward
again. (C) Pass the thread behind the metal
thread guides and then down to the needle.
6. If you want 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. Alternatively, you can use the automatic
needle threader to thread the eye of the needle.
(see page 16)

Automatic Needle Threader
Pull about 6-8” of thread to the back beyond the eye of the needle. This will help prevent the needle
from becoming unthreaded when you start to sew.
!
For safety, turn off the power before using the automatic needle threader.
1. Lower the presser foot lifter. Raise the
needle to its highest position by turning
the handwheel toward you. If you turn the
handwheel backward, the machine will jam
when you start to sew.
2. Pass thread around thread guide.
3. Press lever down as far as it will go. The
threader automatically swings to the threading
position.
4. Pass the thread in front of the needle and under
the hook.
5. To cut the excess thread, take thread tail and
gently slip it over the thread cutter located to the
right of the needle.
6. Release the lever & the thread tail at the same
time, this will form a loop at the back of the
needle.
7. Pull the thread through the needle eye. While
holding the thread, raise the presser foot lifter
and pull the thread under the foot toward the
back.

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.singerco.com.
Here are a few other tips that you may nd 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.
Use the thread cutter on the machine (See Page 7) to trim thread tails when nished sewing. This
is helpful because thread tails are left long enough so that the needle does not become unthreaded
when you start sewing again.
Review the page about Stitch Formation (See Page 19). This will help you understand what the
stitching should look like when you sew.
Depending on the sewing technique you want to do, it may be necessary to change to a different
presser foot. For information on how to do this, see page 29.
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. For information on how to change the needle, see
page 28.
The Speed Control Adjustment Lever is used to control the speed of your machine. This is the
case whether you are using the Foot Control or the Start/Stop Button to start sewing. To increase
the sewing speed slide the lever to the right, to reduce the speed slide the lever to the left. When
you remove your foot from the foot control or you press the Start/Stop Button the machine will stop
sewing.

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.
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.

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.

2. BOBBIN THREAD SHOWING ON TOP OF FABRIC
Possible Cause: Top thread tension too tight.
Solution: Reduce upper thread tension. (See Page 19)
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. (See Page 15)
Possible Cause: Bobbin thread not in bobbin case tension.
Solution: Rethread bobbin. (See Page 14)

12. Fabric Is “Tunneling” Under Stitches
13. Machine Not Feeding Fabric
14. Needle Threader Not Working
15. Loud Noise When Sewing
16. Machine Will Not Run
1. 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 rst raise the presser foot lifter
before starting to thread, so thread can be properly seated in the tension
mechanism and take up lever. (See Page 15)
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.

4. THREAD IS SHREDDING
Possible Cause: Thread is old or poor quality.
Solution: Rethread the top of the machine and bobbin with good quality thread. (See Page 15)
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. (See Page 28)
5. THREAD BUNCHING AT BEGINNING
Possible Cause: Top and 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. (See Page 23)
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 rst few stitches. (See Page 23)
6. SKIPPING STITCHES
Possible Cause: Needle inserted incorrectly.
Solution: Check that at side of needle top is toward back of machine and needle is up as far as
it can go, then tighten needle clamp screw. (See Page 28)
Possible Cause: Wrong needle for fabric sewn.
Solution: Use correct style and 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. (See Page 28)
3. 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). (See Page 15)
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. (See Page 15)
Possible Cause: Upper tension too tight.
Solution: Reduce upper thread tension. (See Page 19)

8. BOBBIN THREAD BREAKING
Possible Cause: Bobbin threaded incorrectly.
Solution: Check that bobbin is placed correctly in the bobbin case. (See Page 14)
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. (See Page 13)
Possible Cause: Dirt or lint in bobbin case.
Solution: Clean bobbin case. (See Page 37)
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 Class 15 transparent bobbins.
9. NEEDLES BREAKING
Possible Cause: Bent, dull or damaged needle.
Solution: Discard needle, insert new needle. (See Page 28)
Possible Cause: Wrong size needle for fabric.
Solution: Insert appropriate needle for fabric type. (Go to www.singerco.com to view the Stitch
Reference Guide)
Possible Cause: Machine not threaded correctly.
Solution: Rethread the machine completely. (See Page 15)
Possible Cause: “Pushing” or “pulling” fabric.
Solution: Don’t manually push/pull fabric in order to sew, but allow the machine’s feed teeth to
draw fabric under the presser foot as you guide it. (See Page 23)
7. 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. (See Page 13)
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.
(See Page 13)
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 ll, then stop to trim the thread tail close to the bobbin. (See Page 13)

11. FABRIC PUCKERS
Possible Cause: Top thread tension is too tight.
Solution: Reduce the top thread tension. (See Page 19)
Possible Cause: Stitch length is set too short for the fabric being sewn.
Solution: Increase stitch length. (Go to www.singerco.com to view the Stitch Reference Guide)
Possible Cause: Wrong style needle for fabric type.
Solution: Use correct needle style. (Go to www.singerco.com to view the Stitch Reference Guide)
Possible Cause: Needle too large for fabric.
Solution: Change to smaller size needle. (See Page 28)
12. FABRIC IS “TUNNELING” UNDER STITCHES
Possible Cause: Fabric is not properly stabilized for the density of the stitches. (for example,
satin stitch applique)
Solution: Add a fabric stabilizer underneath the fabric to help keep the stitches from tunneling in
together, forming a puckered ridge in fabric. (See Appendix in this manual)
13. MACHINE NOT FEEDING FABRIC
Possible Cause: Presser foot lifter has not been lowered onto fabric after threading.
Solution: Lower the presser foot lifter before starting to sew. Don’t “push” or “pull” the fabric as
you sew.
Possible Cause: Feed teeth are lowered.
Solution: If the feed teeth have been lowered, they need to be raised to resume regular sewing.
Possible Cause: Stitch length is set at zero.
Solution: Increase stitch length setting.
10. STITCHES DISTORTED
Possible Cause: “Pushing” or “pulling” the fabric.
Solution: Don’t manually push/pull fabric in order to sew, but allow the machine’s feed teeth to
draw fabric under presser foot as you guide it.
Possible Cause: Incorrect stitch length setting.
Solution: Check for correct stitch length setting. (Go to www.singerco.com to view the Stitch

4. Remove the bobbin from the bobbin case.
5. Take a hold of the bobbin case with your thumb and index nger 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 uff 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 nger 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 nish.
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 t, then the nal 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.
Raw Edge
The raw edge of the fabric refers to the cut edge and usually becomes the edge of the seam
allowance.
Seam
A seam is stitching that joins two fabrics together, includes the main stitching line and the
seam allowance.
Seam Allowance
The seam allowance is the amount of fabric between the seam stitches and the raw edge of
the fabric. The most popular seam allowance are 5/8” and 1/2”.
Seam Finish
Seam nishing is stitching used to keep a raw edge from unraveling or fraying.
Stabilizer
Stabilizer is special material used to provide additional support for stitches for special
techniques such as decorative machine stitching, appliqué, buttonholes and more.
Topstitching
Topstitching is straight stitching that appears on the top side of the fabric, used for adding
strength, embellishment or both.
