machine, as shown in the drawing.
Push the table back into place to reattach the exten-
sion table.
Accessory Box
The extension table is also a storage box. Pull the
door open to see the storage space.
Centimeter/Inch Measurements
Use this handy tool located on the lower portion of
the front of the machine for quick measurements.
Circular Sewing Pivot Points
The extension table has holes that are 1 cm apart
from each other. Use the holes to sew circles and
scallops with the optional pivot pin.
Foot Pressure Dial
Set the pressure dial at “3” for regular sewing.
Depending on the weight of your fabric, you may
need to increase (higher number) or decrease (lower
number) the pressure.
4

Additional Presser Foot Clearance
You can raise the presser foot higher than the nor-
mal up position for easy removal of the presser foot
or to place heavy fabrics under the presser foot. Pull
the presser foot lever up beyond the normal up posi-
tion.

Stitch Length Knob
Turn the stitch length knob. The lower the number,
the shorter the stitch length. The higher the number,
the longer the stitch length.
Each stitch will have a suggested length range.
Fine Tuning Stretch Stitches
If the stretch stitch doesn’t look right, you can
adjust it.
If stitches are too short, correct by turning the knob
toward the “+”.
If stitches are too long, correct by turning the knob
toward the “-“.
Stitch Width/Needle Position Dial
The needle must be at a high position before chang-
ing stitch width. Turn the flywheel toward you to raise
the needle.
The lower the number, the narrower the stitch. The
higher the number, the wider the stitch. The widest
width this machine can sew is 5 mm.
Straight Stitch and Triple Seam can sew from differ-
ent needle positions.
• center needle position – set dial between 3
and 5
• left needle position – set dial between 3 and 0,
with 0 being the farthest left
Reverse Stitch Lever

Thread Tension Dial
Straight Stitch
In straight seams, the needle thread and the bobbin
thread should lock together in the center of the two
layers of fabric.
If you look at the top and bottom of the stitch, you
will notice that there are no gaps; each stitch is
smooth and even.
When adjusting needle thread tension, the higher the
number, the tighter the needle thread.
Here are some reasons you may change the thread
tension dial:
1. The fabric is stiff or heavy.
2. You are sewing more than two layers of fabric.
3. The stitch you are using needs the threads not to
lock together in the center of the fabric.
• Tension is too tight
The bobbin thread shows through on the topside of
the fabric and it will feel bumpy.
Turn the dial to a lower number to loosen the needle
thread tension.
• Tension is too loose
The needle thread shows through on the underside
of the fabric and it will feel bumpy.
Turn the dial to a higher number to tighten the
needle thread tension.
• Adjusting Tension for Zigzag and
Embroidery
The upper thread tension should be slightly weaker
when sewing a zigzag or a satin stitch. The upper
thread should appear slightly on the underside of the
fabric.

SECTION II
Getting Ready to Sew
Selecting the Correct Needle and Thread
There are many kinds of fabrics, threads and
needles. It is important to use the correct ones to-
gether.
Always purchase good quality thread. It should be
strong, smooth and even in thickness. Use the same
thread for needle and bobbin. Always test thread and
needle size on a scrap piece of fabric.
In general, fine threads (the larger the number, the
finer the thread) and needles (the smaller the num-
ber, the finer the needle) are used for sewing light-
weight fabrics and heavier threads and larger
needles are used for sewing heavyweight fabrics.
There are many specialty needles available from
your sewing machine dealer.
Check your needles frequently for rough or blunt
tips. Snags and runs in knits, fine silks and silk-like
fabrics are permanent and are often caused by dam-
aged needles.
Changing the Needle
Turn off the machine. Turn the flywheel toward you
to raise the needle. Lower the presser foot.
Turn the needle clamp screw counterclockwise to
loosen.
Remove the needle from the clamp.
Insert the new needle into the clamp with the flat
side to the back, pushing it up as far as it will go.
Tighten the clamp screw firmly.
To determine if the needle is defective, place the flat
side of the needle on something flat (a needle plate,
piece of glass, etc.). The gap between the needle
and the flat surface should be even.
Never use a bent or broken needle. It may cause
skipped stitches or thread breakage. Defective
needles can ruin the fabric.
Always purchase good quality needles. Change
needle often.

5. Eye
6. Point
Universal – an all-purpose needle that handles most
woven and knit fabrics. A universal needle size 14/90
comes inserted in your machine.
Ball point – the point spreads the fibers, preventing
tears and is especially suited for knit fabrics. Not
recommended for embroidery.
Denim – the sharp tip effectively pierces densely
woven fabrics such as denim and canvas.
Stretch – specially designed to prevent skipped
stitches in synthetic suedes and elasticized knits
(swimwear).
Leather – the cutting point creates small holes in
leather and suede.
Topstitching – the extra sharp tip penetrates layers
of fabrics; extra large eye and large groove accom-
modate heavyweight topstitching thread.
Twin/Double – 2 needles are joined on a crossbar
and share a single shaft. Sews two parallel rows of
stitching. Available in universal and ballpoint.

Straight Stitch
The straight stitch is used to sew a seam in woven
fabrics and may also be used for gathering, basting,
sewing in a zipper, pintucks, rolled hems and twin
needle hems.
NOTE: Fine fabrics should have a stitch length be-
tween 1.5 and 2.5, medium fabrics between 2.0 and
3.0 and heavier fabrics between 3.0 and 4.0.
Starting To Sew
Raise the presser foot and position the fabric next to
a seam allowance line on the needle plate. Lower
the needle to the point where sewing is to begin.
Pull the threads under the foot towards the back and
lower the presser foot. Press the foot control. Gently
guide the fabric along the seam allowance line letting
the fabric feed naturally.

Gathering
Gathering/shirring evenly distributes fullness in an
area with very tiny pleats. Gathering is one row or
two parallel rows. Shirring is three or more parallel
rows. Light to medium weight fabrics provide the
best results.
Decrease tension to 2.0 – 4.0.
Increase stitch length to 4.
Sew two rows of parallel stitches. Sew first row next
to raw edge using foot edge as guide. Sew second
row next to first row using foot edge as guide. Leave
long thread tails at beginning and end of each row.
Pull the bobbin threads simultaneously from each
end of the fabric until the desired amount is gath-
ered.
Knot the threads at each end and distribute the gath-
ers evenly.
Reset machine settings to straight stitch. See page
18.
Sew between two rows of stitching to secure gather-
ing.
OR
Lay gather fabric over flat fabric and sew the two
fabrics together directly on the second row of gather-
ing stitches.

Zipper Insertion
(Model 2100 – optional foot)
• Lapped Application
Lapped zippers are usually inserted into a side seam
of skirts or pants, for example.
Attach the pin on the zipper foot to the groove on the
shank.
• To sew the left side of the zipper, attach the zip-
per foot on the right-hand side.
• To sew the right side of the zipper, attach the
zipper foot on the left-hand side.
• Fabric Preparation
Add 1 cm (3/8”) to the zipper size. Use this measure-
ment and mark the opening for the zipper.
Place right sides of fabric together and sew the
seam located below zipper placement. (Make sure to
reverse sew the stitches directly below the zipper
placement.)
Increase stitch length to 4 and baste the zipper
opening closed. Press the seam and basting seam
open.
Open zipper and place it face down on the seam
allowance. Teeth are on the seam line and zipper top
is 1 cm (3/8”) from fabric top edge. Attach foot with
left side pin. Baste zipper in place, sewing from bot-
tom to top.
Close zipper. Turn zipper face up (right seam allow-
ance forms a small fold at basting line) and smooth
zipper teeth away from seam. Attach foot with right
side pin. Reset straight stitch length to 2.5. Starting
at the bottom, sew through the folded seam allow-
ance and zipper tape.
