Application
Straight Stitch
Center Position
The basic stitch used for sewing. The most common use for a straight stitch is to
sew two pieces of fabric together.
Use stitch with longer stitch length when sewing in heavy fabric.
Straight Stitch
Left Position
Use for top stitching.
Zigzag Stitch A very versatile stitch for decorative sewing, applique, attaching trims, and
more.
Satin Stitch Use for decorative sewing and appliqués.
Multi-Step
Zigzag Stitch
Finish seam allowances to prevent the fabric from unravelling. When seam
nishing, the smaller step of the stitches will help keep fabric more at than a
regular zigzag. It can also be used for mending tears and sewing elastic.
Blind Hem
Stitch
Sew hems that are practically invisible from the right side of the fabric. It is
used for skirts, dresses, trousers, curtains, etc, made with non-stretch fabrics.
Stretch Blind
Hem Stitch
Sew hems that are practically invisible from the right side of the fabric. It is
used for garments and other projects made with stretch knit fabrics.
Buttonhole Sew buttonholes on home decór, garments, crafts and more.
Stitch Overview
The stitches described in the below chart are utility stitches, used mainly for utility sewing. When sewing, use a thread tension be-
tween 3–5. Always test sew on a piece of scrap fabric, and adjust the tension if necessary.
All-purpose Foot (J) (attached to the machine upon delivery)
This foot is used for general sewing on most types of fabric. The bottom of the
foot is at, so that the fabric is held down rmly against the feed teeth while
sewing. It also has a wide slot so that the needle can move from left to right,
depending on which stitch you sew.
Zipper Foot (I)
This foot is used for inserting zippers. Attach the foot to the presser foot holder
on either side of the foot, depending on which side of the zipper is being sewn.
The Zipper Foot can also be used to create and insert piping.
Four–Step Buttonhole Foot (D)
This foot is used for making a 4–step buttonhole. This foot holds the fabric
securely as you sew the top, bottom, left side and right side of your buttonhole.

Needles
The sewing machine needle plays an important role in successful sewing. Use only quality needles. We recommend needles of system
130/705H. The needle package included with your machine contains needles of the most frequently used sizes.
Be sure to match the needle to the thread you are using. Heavier threads require a needle with a larger needle eye. If the
needle eye is too small for the thread the needle threader may not work properly.
Note: To avoid the needle break, use only medium/low speed and recommended needle on thick fabrics works.
Change the needle often. As a general rule, needles
should be changed every 6-8 hours of actual stitch-
ing time.
Important Needle Information
Always use a straight needle with a sharp point and make sure
the point is not bent or damaged (A).
A damaged needle (B) can cause skipped stitches, breakage or
snapping of the thread. It can also damage the needle plate.
Do not use asymmetrical twin needles (C), they can damage
your sewing machine.
Note: Before you begin changing the needle, it can be helpful
to place a small piece of paper or fabric underneath the needle
area, over the hole in the needle plate, so that the needle doesn't
accidentally fall down into the machine.
1. Loosen the needle clamp screw. If it feels tight, use the
screwdriver from your accessories to aid with loosening the
screw.
2. Remove the needle.
3. Push the new needle upwards into the needle clamp with
the at side of the needle away from you.
4. When the needle will go up no further, tighten the screw
securely.

Thread Tension
To set the thread tension, turn the dial on the front of the
machine. Depending on the fabric, thread, etc, the tension may
need to be adjusted. For the best stitch appearance and durabili-
ty, make sure the needle thread tension is correctly adjusted.
When sewing, use a thread tension between 3–5
For general sewing, the threads evenly meet between the two
layers of fabric (A).
If the bobbin thread is visible on the top side of the fabric, the
needle thread tension is too tight (B). Reduce the needle thread
tension.
If top thread is visible on the underside of the fabric, the needle
thread tension is too loose (C). Increase the needle thread
tension.
For decorative stitches and buttonholes, the top thread should
be visible on the underside of the fabric.
Make a few tests on a scrap piece of the fabric you are going to
sew and check the tension.
Select a Stitch
Turn the stitch selector dial to the left or right until the stitch you want
to sew is lined up with the dot marking above the dial.
Reverse Sewing
To secure the beginning and the end of a seam, press down the
reverse lever. Sew a few reverse stitches. Release the lever and
the machine will sew forward again.

SEWING
Start to Sew – Straight Stitch
Next to each stitch or sewing technique described in this section of the
manual is a chart showing the recommended settings and presser foot.
See sample of the chart to the right.
The recommended settings are also shown on the display, but might
need adjustment to t a special technique.
Note: Some fabrics have a lot of excess dye which can cause discolor-
ation on other fabric but also on your sewing machine. This discolor-
ing may be very dicult or impossible to remove. Fleece and denim
fabric in especially red and blue often contain a lot of excess dye. If you
suspect that your fabric/ready-to-wear garment contains a lot of excess
dye, always pre-wash it before sewing to avoid the discoloring.
Note: For best sewing result, use the same thread on top and bobbin. If
sewing with specialty/decorative threads, use regular sewing thread in
the bobbin.
Note: When sewing in light weigt fabrics, always use stabilizer under
the fabric. This is to make sure the fabric feed correctly and that the
stitches are formed correctly.
Set your machine for straight stitch (see chart to the right).
Raise the presser foot and position the fabric under it, next to a
seam allowance guide line on the needle plate or bobbin cover.
Place the top thread underneath the presser foot.
Lower the needle to the point where you want to start. Bring
the threads toward the back and lower the presser foot. Press
the foot control. Gently guide the fabric along the seam guide
letting the machine feed the fabric (A).
Note: Do not forget to bring up the bobbin thread before start-
ing to sew (see page 10).
To secure the beginning of a seam, press and hold the reverse
lever. Sew a few reverse stitches. Release the reverse lever and
the machine will sew forward again (B).

To change sewing direction, stop the machine and turn the
handwheel toward you to bring the needle down into the fabric.
Raise the presser foot.
Pivot the fabric around the needle to change sewing direction
as desired. Lower the presser foot and continue sewing in the
new direction.
Change Sewing Direction
Press and hold the Reverse lever and sew a few stitches in reverse when you reach the end of the seam. Release the button and sew
forward again to the end of the seam. This will secure the seam so the stitches don't unravel.
Turn the handwheel toward you to raise the needle to its highest position. Raise the presser foot and remove the fabric, pulling the
threads to the back.
Pull the threads up and into the thread knife so that the threads are cut the proper length and your needle won't come unthreaded when
you start the next seam.

Multi-Step Zigzag Stitch
Multi-step zigzag stitch is used to overcast raw edges. Make
sure the needle pierces the fabric on the left side and overcasts
the edge on the right side.
The stitch can also be used as an elastic stitch to allow seams to
stretch when sewing knit fabrics. Set up for multi-step zigzag stitch
The blind hem stitch is used to make invisible hems on skirts,
trousers and home décor projects. There are two types of blind
hem; one is recommended for medium to heavy woven fabric
(1), the other for medium to heavy stretch fabric (2).
• Finish the raw edge of the hem if sewing on a woven
fabric. There is no need to nish the raw edge rst on most
knits.
• Fold and press the hem allowance to the wrong side.
• Fold the hem back on itself so approximately 3/8" (1 cm)
of the nished edge extends beyond the fold. The wrong
side of your project should now be facing up.
• Place the fabric under the presser foot so that the fold runs
along the presser foot as illustrated (A).
• When the needle swings into the fold it should catch a
small amount of fabric.

To cover large holes it is necessary to sew a new piece of fabric
onto the damaged area.
Baste the new piece of fabric onto the damaged area on the
right side of the fabric.
Sew over the fabric edges with the zigzag or the multi-step
zigzag stitch.
Trim the damaged area close to the seam from the wrong side
of the fabric.
On tears, frayed edges or small holes it is useful to lay a piece
of fabric on the wrong side of the fabric. The underlayed fabric
reinforces the damaged area.
Lay a piece of fabric underneath the damaged fabric. It must be
a little larger than the damaged area.
Sew over the damaged area using the zigzag or multi-step
zigzag stitch.

hole stitch “ac”. Sew the second bartack (F). Stop when the
needle is at the rigt side of the bartack.
7. Raise the needle to its highest position and select button-
hole stitch “d”. Sew the right side of the buttonhole to the
same length as the rst column (G).
8. To secure the bartack, thread the end of the top thread into
a hand sewing needle, pull to the wrong side and tie the end
before cutting excess thread ((H).
9. Use a seam ripper and cut the buttonhole open from both
ends towards the middle (I).
Note: Always sew a test buttonhole on a piece of scrap fabric.
Four-Step Buttonhole
Buttonhole Balance
If the density of the buttonhole columns dier, you can adjust the
stitch density of the buttonhole. The buttonhole balance dial (A)
is found on the right side of the stitch selection dial. Only the left
column of the buttonhole will be adjusted. Balance it to match the
right buttonhole column.
Normally, the dial should be placed in a neutral position (B).

MAINTENANCE
Cleaning the Machine
Cleaning the Bobbin Area
Raise the needle and turn o the machine.
Raise the needle and turn o the machine.
Cleaning under the Bobbin Area
To keep your sewing machine operating well, clean it often. No lubrication (oiling) is needed. Wipe the exterior surface of your ma-
chine with a soft cloth to remove any dust or lint built up.
Remove the presser foot. Slide o the bobbin cover and re-
move the bobbin.
Clean the feed teeth and the bobbin area with the brush found
among the accessories.
Attach the presser foot, insert the bobbin and replace the bob-
bin cover.
Clean the area under the bobbin case after sewing several
projects or any time you notice an accumulation of lint in the
bobbin case area.
Remove the presser foot. Remove the screws in the needle
plate by using the screwdriver. Lift up and remove the needle
plate.
Remove the bobbin case by lifting it up.
Clean the area with the brush or with a dry cloth.
Note: Do not blow air into the bobbin case area. The dust and
lint will be blown into your machine.
Guide the “forked” end of the bobbin case (A) under the feed
teeth from left to right. The bobbin case should be placed uder
the feed teeth and under the spring (B). The mark (C) on the
bobbin case should be aligned with the mark (D) on the the
hook race for easy placement. Move the bobbin case slightly
until it slips correctly into the hook race (E). To make sure the
bobbin case is properly replaced, turn the handwheel towards
you. The hook race should rotate freely in a counter-clockwise
direction.
Place the needle plate over the feed teeth, replace and tighten
the screws.
Attach the presser foot and replace the bobbin.

Troubleshooting
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 thread tension mechanism and has
not been threaded through the take up lever.
Solution: Rethread the 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. To know if you have rethreaded the machine
correctly, try this 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 the presser foot and begin sewing.
If you put the presser foot lifter down, but the thread still pulls freely (you feel no dierence whether the presser
foot is up or down), this means that you have threaded incorrectly. Remove the upper thread and rethread the
machine.
Bobbin Thread Breaking
Possible cause: Bobbin threaded incorrectly.
Solution: Check that bobbin is placed correctly in the bobbin holder.
Possible cause: Bobbin wound too full or unevenly.
Solution: Bobbin thread may not have been correctly placed into bobbin winding tension disc during the bobbin winding
process.
Possible cause: Dirt or lint in bobbin holder.
Solution: Clean bobbin holder.
Possible cause: Wrong bobbins being used.
Solution: Use bobbins that are the same style as those that come with the machine (SINGER® Class 15 transparent
bobbins) – don’t substitute.
Bobbin Thread Showing on Top of Fabric
Possible cause: Top thread 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.
Bobbin Winding Di󰀩culties
Possible cause: Bobbin thread loosely wound on bobbin.
Solution: Rewind bobbin, making sure that the thread is placed snuggly in the bobbin winding tension disc.
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
ll, then stop to trim the thread tail close to the bobbin.

Fabric Puckers
Possible cause: Top thread is too tight.
Solution: Reduce top thread tension.
Possible cause: Wrong style needle for fabric type.
Solution: Use correct needle style and size for your fabric.
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.
Loud Noise When Sewing
Possible cause: Thread not in take-up lever.
Solution: Rethread the machine, making sure the take up lever is in its highest position so thread goes in the eye of the take
up lever — turn machine hand wheel toward you to raise the take up lever to its highest position for threading.
Possible cause: Thread path is obstructed.
Solution: Check that thread is not caught on the thread spool or behind the spool cap.
Machine is 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.
Machine Will Not Run
Possible cause: Bobbin winding spindle is engaged when you try to sew.
Solution: Disengage bobbin winding spindle by pushing it to the left.
Possible cause: Power cord and/or foot control not plugged in correctly.
Solution: Make sure power cord/foot control are correctly seated in machine and power supply.
Possible cause: Wrong bobbins being used.
Solution: Use bobbins that are the same style as those that come with the machine (SINGER® Class 15 transparent
bobbins)– don’t substitute.
Needles Breaking
Possible cause: Bent, dull or damaged needle.
Solution: Discard needle, insert new needle.
Possible cause: Wrong size needle for fabric.
Solution: Insert appropriate needle for fabric type.
Possible cause: Machine not threaded correctly.
Solution: Rethread the machine completely.
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.
