How Your Machine Operates
Awareness of its simple operation will enable you to become more proficient in its use. Please read all
instructions before using your new machine.
E
R
V
I
E
W
Use one, two or three chain/cover stitch needles and one looper for a chain or cover stitch.
When forming a chain stitch, the chain needle thread catches the chain looper to form a straight stitch
on the top of your fabric and thread chain loops on the underside. Use 2 or 3 cover stitch needles and
the chain looper to form a double or triple row of straight stitching on the top and a weave of thread on
the underside of your fabric.
After setting up your machine for the first time, take a few moments to learn how it sews. Before your
machine is threaded, turn the handwheel toward you and watch the operation of the various parts.

Thread
All types of thread may be used on your Baby Lock, but 100% longstaple polyester thread, cross
wound on a cone, consistently provides the best stitch performance. Because the threads must pass
through several thread guides at high speeds, they must be of uniform thickness and high strength
with a minimum amount of linting.
Goodquality cotton or cottoncovered polyester threads sew well, though they produce more lint, cre
ating the need to clean the machine more frequently. Poor grades of thread can result in frequent
fraying, breaking and unbalanced stitches.
Threads of other fiber contents and weights may be used, depending on their strength and thickness.
Testing will help you determine how easily they can pass through the thread guides, thread slots, nee
dles and loopers.
Important Note: For maximum performance of the Baby Lock, it is recommended to use "100% poly
esterlong fiber thread". Recommended brands are MaxiLock and Metrosene. This thread also per
forms best when used with many decorative threads for sewing specialty decorative techniques.

Setting Up Your Baby Lock
1. Remove machine from box
After removing the packing materials from the
box, gently lift your Baby Lock by grasping the
handle provided on the top of the machine.
Place the machine on a sewing table or any
level surface that provides ample work area to
the left. Place the foot controller in a pedal stay,
if desired, and place it under the sewing table.
A
2. Plug in the machine
Plug the power cord into the machine first, then
into a wall outlet. The power switch is located
toward t h e back on t h e ri g h t side of t h e
machine. Always make sure the power is off
when t h e ma c h i n e is not in use ( f i g . A ) .
Available foot controller for U.S.A.: Model YC
482 or YC420W.
3. Polarized plug
This appliance has a polarized plug (one blade
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 the plug 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.
4. Foot controller
The sewing speed of the machine is deter
mined by the amount of pressure applied to the
foot controller. When not in use, do not place
anything on the foot controller, or the machine
could start inadvertently and the controller or
motor could burn out.

There is a thread cutter located on the left side of your machine. At the
end of a seam, sew off the fabric edge and continue sewing to create a
5 6 inch(12 15cm) thread chain.
Bring the chain of thread up and back and pull forward into the thread
cutter.
Presser Foot Pressure Adjustment
The presser foot pressure has been preset at the factory and rarely
needs adjustment. You may find it necessary, however, to decrease
the pressure for thick fabrics or increase pressure for thin fabrics to
feed more smoothly under the foot. Use a coin to turn the screw on top
of the machine.
To increase pressure, turn the pressure adjusting screw clockwise.
To decrease pressure, turn the screw counter clockwise.
SnapOn Presser Foot
The Baby Lock has the convenience of a snapon presser foot.
To Release:
1. Raise the presser foot lever. This will also lower the feed dogs out of
the way.
2. Raise the needles to the highest position.
3. Push the presser foot release lever located at the back of the presser
foot holder.
4. Slide the presser foot to the left of the needles.

very light weight fabrics, you may prefer a shorter stitch length. When sewing heavier fabrics, you may
choose to lengthen the stitch (fig. B).
niently located just to the left of the front
cover, near the base plate (fig. A). The
dial shows the stitchlength ranging from
1, for the shortest stitch, to 4 for the
longest.
Simply turn the dial aligning the desired
setting with the indicator mark on the
Differential Feed
Your Baby Lock Cover Stitch is equipped with differential feed.The
set of feed dogs work independently in order to ensure smooth
sewing on all fabrics (fig. A)
When the differential feed adjusting lever, located at the machine's
right, front edge is set on "N" for normal feeding, the feed dogs move
the same distance. This is the setting to use for most fabrics and
applications (fig. B).
A
V
E
R
V
I
E
W
When the dial is set above "N", the front feed dog will feed more fab
rics than the back. This is because the front feed dog moves at a
greater distance than the back feed dogs. As a result, the fabric
becomes compressed or eased, as the diagram on the front cover
indicates. This can eliminate wavy seams in stretchy fabrics or those
cut on the bias grain.
At the maximum setting of 2.0 (fig. C), the differential feed can gath
er a lightweight fabric to nearly double fullness (fig. D).
The front feed dog is actually feeding in twice as much fabric as the
back feed dog is feeding out. To maximize the gathering effects, use
the longest stitch length setting. Fabric weight will affect the gather
ing. Test stitch for desired results.
When the differential feed lever is set below "N" (fig. F), the front feed
dog moves less distance than the back feed dog. This adjustment
stretches the fabric slightly as it is sewn. The lower settings prevent
puckers on lightweight fabric (fig. E).

When using standard sewing thread spools, use the sponge disks
(sponge side up) and spool caps (on top of spool) to prevent the
thread from tangling. (fig. B)
Thread nets can be placed over threads that tend to slip off the
spool during sewing. For example: rayon, silk, nylon, invisible, and
decorative threads. Place the thread net over the spool of thread
and fold net back, (fig. C) Pull thread from the top of spool to enable
the thread to feed evenly. (fig. D)

Front Cover Seam Guide
There are marks on the bed of the Baby Lock that can be used as a guide while sewing.
It will depend on what cover or chain stitch needle position you will be using as to what the width will
be.
For example, the first mark on the left closest to
the needle plate, C1 needle is 1 inch (2.5cm),
C2 needle is 7/8 inch (2.25cm), and C3 nee
dle is 3/4 inch (2cm).
This guide is great for hemming garments with
cover stitch.
1. Turn under hem and press.
2. Align the raw edge of the hem with the needles
3. Align the folded edge of hem with the correct
guide mark.
16
Rethreading Looper
If a thread breaks, raise the presser foot and pull the broken thread from under the foot. Open the front
table, depress the machine lock button.. Rethread the machine above the threading port, leaving an
18inch (40cm) thread tail. Thread the looper as usual and move lock button release lever to the right.
Close the front cover and sew a test sample.
Note: When rethreading your Baby Lock using the "JetAir Threading" feature, make sure that the
previous thread that was in the looper (tube) is completely removed. This will eliminate any chance of
the previous thread obstructing the flow of the air when rethreading the machine.
Page 19
Start to Sew
When threading is complete, the loose threads should initially interlock on fabric. This is most impor
tant when sewing the chain or cover stitches.

To ChainOff of the Fabric
Your BLCS will sew a chain off the edge of the fabric. For best results, we recommend to follow the
instructions below.
1.At the end of the seam, change the stitch length to 4 (fig.A).
2. Let the thread flow from the back of the 24 inches without pulling (figB).

Chain Stitching
The chain stitch is formed using two threads, one thread in the needle and one thread in the chain
looper.
Chain Stitching looks like a straight stitch on the top of the fabric while the chain looper thread forms a
chain on the underside of the fabric. The chain stitch has stretchability that is not found in the conven
tional locked straight stitch from a sewing machine. The chain stitch is used to stabilize seams in
woven fabrics and where needed in knit fabrics. The chain stitch can also be used for sewing wide
elastic in garments and applying bias tape.
For Chain Stitch:
1. Place the machine in locked position to thread the chain looper.
2. Follow the diagram to thread the chain looper, (see pg. 19). Open side cover of machine to make
sure the thread is through the eye of the chain looper. Trim thread to 4 inches (10cm) and lay in tray.
3. Follow the guide to thread the chain/cover stitch needle, (C1, C2, or C3). Place needle thread on
top and to the left of presser foot before sewing.
4. Move the lock button release lever to the right.
5. Set stitch length and other machine adjustments(See chart below).
6. Place the fabric under the needle and turn handwheel toward you two or three stitches in the fabric.
Cut the excess threads and start sewing.
Note: All chain and cover stitches must be started with fabric under the needle.

Turning Corners Chain Stitch
Sew to the point in fabric where you want to turn a corner. Stop the machine. Turn the handwheel
toward you (counter clockwise) by hand, making sure the needle is going down in the fabric. Slowly
start to raise the needle OUT OF FABRIC. Stop when you see the eye of the needle. (The point of the
needle will still be in the fabric.) Raise the presser foot (fig. A), and slowly pivot the fabric (fig. B). Lower
the presser foot and continue to sew (fig. C).

Securing Chain and Cover Stitching
The Chain Stitch and Cover Stitch can easily be removed. Trim the chain tail to edge of fabric and the
"end" of the seam and pull on the chain looper thread on underside of the fabric. This will give you the
opportunity to "Unsew" an incorrect seam very easily.
H
N
I
Q
U
E
S
To secure the chain stitch or cover stitch, at the end of the seam, bring the needle thread(s) to the back
of the fabric and tug on the needle threads to secure the seam.
The cover stitch needle threads may also be tied to prevent raveling of the stitch.
To secure the beginning of the Cover stitching the thread tail can be brought around to the front of the
needles and caught into the cover stitching. (This technique is not for chain stitch)
See illustration below.

Page 33
Using Specialty Threads
Stitching with specialty threads can form beautiful stitches. These heavy or shiny threads can be used
to enhance the appearance of a stitch and create special effects.
S
P
Some specialty threads work well through the needle and chain looper, while others are too heavy to
be threaded through the needle and are for chain looper use only.
Use the "Specialty Thread Guide Chart" (pg. 35) as a guide for the specialty threads. Keep in mind
that the quality of the thread may vary and tension setting will vary from thread to thread. Make a test
sample before starting on the project.
Lightweight Threads
Lightweight threads such as rayon machineembroidery thread, lingerie thread, can easily be thread
ed on the Baby Lock. Very fine monofilament threads may need threading assistance of a "Threading
Cradle" (pg. 34) or "Looper Threading Tool" (pg 33)

Medium weight Threads
Medium weight threads, such as topstitching thread, Décor rayon, stretch nylon thread are too bulky
to easily "jetair" through the threading port and looper. By using a "Threading Cradle" (pg.34) or
"Looper Threading Tool" (pg.33), the heavier threads can be threaded easily in the Baby Lock.
Heavy weight Threads
Heavy weight threads such as Pearl Crown Rayon, Décor 6, and Candlelight will need extra atten
tion in the chain looper. Directions for bypassing the threading port (pg. 32) may need to be used for
heavy weight thread.
Please follow the Specialty Thread Guide Chart (pg. 35) for special instructions concerning the use of
these threads.

Bypassing the Threading Port
Heavyweight threads can be used through the chain looper thread
paths. Specific techniques may require that the thread bypass the
thread port for the thread pull to be loosened. Start with the
machine threaded with regular serger thread.
1. Open front cover and raise the presser foot.
2. Just above the threading port, clip the chain looper thread. Pull
the thread out of the upper guides and remove the thread cone.
3. Place the specialty thread on the spool pin. Thread it into the
upper guides and tension disk. Bring the thread end through
the hole just left of the jetair threading port. (This will allow the
front door to be closed while sewing. Leave approximately 12
inches (30cm) of thread to be threaded through the chain loop
er. (fig. A).
4. With machine lock button released, use the tweezers to pull the
existing looper thread out of tube extending from the threading
mechanism (fig. B). Leave the thread in the looper arm.
5. Tie the specialty thread onto the regular thread with an over
hand knot (fig. C). Pull on the regular thread from the looper
eye until the specialty thread comes through the looper eye.
6. Lay the thread end in the chain looper tray and close the side
door. (fig.D)
A
B
C
A
D
S
If the thread is heavy and the overhand knot (step #5) is too large
for the looper tube, follow directions #1 thru #6 on page. 34 to
make a thread cradle. Then:
1. Release machine lock button.
2. While holding the loose ends of the thread cradle with one
hand, use the tweezers to pull the cradle loop out of the tube
extending from the threading mechanism with the other hand.
3. Insert 2 inches (5cm) of the decorative thread into the cradle
loop. Pull on the loose ends of the thread cradle from the loop
er eye until the specialty thread comes through the chain looper
eye.Lay in the chain looper tray and close the side door.

Looper Threading Tool
1. Open the front cover and raise the presser foot.
2. At the threading port, cut the chain looper thread. Remove
chain looper thread from under the presser foot and the upper
thread guides. Replace cone of thread with specialty thread.
3. Place the machine in "locked" position to thread the chain
looper.
4. Thread specialty thread into the upper thread guides, leaving
A
B
an 18inch (40cm) tail above the threading port.
5. Place the straight end of the looper threading tool into the
threading port. Push the looper threading tool until the end
comes out of the looper eye. Open side door of machine to
see threading tool come out of the eye of chain looper.
6. Insert the specialty thread tail into the looper threading tool
eye (fig.A). Pull the straight end of the looper threading tool
through the looper eye bringing the specialty thread with it.
