How Your Machine Operates
Sometimes called an overlock machine or overlocker, the serger is different from any conventional
sewing machine you have used. Awareness of its simple operation will enable you to become more
proficient in its use. Please read all instructions before using your new machine.
A serger is kind of a knitting process that loops two, three or four threads together to create a stitch.
Your Baby Lock Ovation operates with one or two needles in the overlock position and one or two
loopers to form an overlock stitch. Use one, two or three chain/cover stitch needles and one looper
for a chain or cover stitch. Uniquely independent of each other, you can use any of the overlock or
chain/cover stitch selections separately or in combination.
When fabric is placed in front of the presser foot, it reaches the feed dogs first. The feed dogs move
the fabric along as the cutting blades trim the fabric edge, creating a clean edge to be finished.
Or disengage your blade and insert the sewing table to sew a chain stitch in the center of your
fabric.
The overlock stitch is supported by one or more parallel "stitch finger(s)" that keep the fabric flat.
To form an overlock stitch, the threads become "locked" "over" the edge of the fabric encasing the
raw edge with thread to prevent fabric raveling. 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 slowly toward you several times and watch the operation
of the various parts.

Needles
Thread
All types of thread may be used on your Baby Lock, but 100% polyester long fiber thread,
crosswound 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 while producing a minimum amount of lint.
Good quality cotton or cotton covered polyester threads sew well, though they produce more lint,
creating the need to clean the machine more frequently. They work well for overedging and seam-
ing, but they may be too weak or too fuzzy for the rolled edge. 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 the stitch quality and how easily the threads can pass through the
thread guides, thread slots, needles and loopers.
Important Note: For maximum performance of the Baby Lock Ovation, it is recommended to use
"100% polyester long fiber thread". This thread also performs best when used with many decorative
threads for sewing specialty decorative techniques.

Setting Up Your Ovation
1. Remove machine from box
After removing the packing materials from the
box, gently lift your Baby Lock serger by grasping
the handle provided on the top of the machine.
Place the machine on a serger sewing table or
any sturdy level surface that provides ample work
area to the left. Place the foot control in a pedal
stay, if desired, and place it under the sewing
table.
2. Plug in the machine
Before connecting the power supply, make sure
the voltage and frequency shown on the machine
conforms to your electrical power.
With the overlock machine turned off, insert the
foot control jack and the power cord plug into
their appointed connectors. (fig. A) Then plug
the power cord into an electrical wall outlet.
Always make sure the power is off when the
machine is not in use. (fig. A) Available foot
control: Model YC-485EC or 4C-333C.
3. Polarized plug
This appliance has a polarized plug (one blade
wider than the other). To reduce the risk of elec-
tric shock, this plug is intended to fit in a polarized
outlet only one way. (fig. B) 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. o not modify the plug in any way.
4. Foot controller
The sewing speed of the machine is determined
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.
Lay the foot control cord along the inside of the
channel located on the bottom right side of the
overlock machine. (fig. C)
5. Extension thread stand
To insert the extension thread stand:
Place the pegs into the slots on the back of the
main thread stand.
Push the extension thread stand into the main
thread stand until it snaps into place. (fig. )
To remove:
Using both hands squeeze together the upper
section of the stand support braces that are
located just underneath the stand while gently
raising it up and out to release from the main
thread stand.

Thread Cutter
Presser Foot Pressure Adjustment
Snap-On Presser Foot
There is a thread cutter located on the left side of your Ovation.
At the end of a seam, sew off the fabric edge and continue sewing to
create a 5-6 inch (12.5-15cm) thread chain.
Bring the chain of thread up and from the back to front through the
thread cutter.
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. Turn the adjusting dial on left side
of the machine.
To increase pressure, turn the pressure adjusting dial counterclock-
wise.
To decrease pressure, turn the dial clockwise.
The Ovation has the convenience of a snap-on presser foot
system.
To Release:
1. Raise the presser foot thread release lever to highest
position.
2. Lock the cutting blade down.
3. Raise the needles to their highest position.
4. Push the presser foot release lever located at the back of the
presser foot holder.
5. Slide presser foot slightly toward you and carefully turn the
back section of foot clockwise 90 degrees.
6. Slide the presser foot to the rear to remove.
To Replace:
1. Raise the presser foot thread release lever.
2. Lock the cutting blade down.
3. Raise the needles to the highest position.
4. Slide the foot from the left to right.

Stitch Width
The stitch length / rolled hem adjusting dial is conveniently located just
to the left of the cutting blade cover, near the base plate. (fig. A) The
dial shows two stitch-length ranges, from 0.75, for the shortest stitch,
to 4 for the longest. As the dial indicates, one range is for standard
sewing and one is for rolled edging or narrow seaming.
Simply turn the dial aligning the desired setting with the indicator mark
on the machine. A stitch length of 3mm, or about 10 stitches per inch
is ideal for seaming and overedging most fabrics. For overedging or
seaming very lightweight fabrics, you may prefer a shorter stitch
length. When sewing heavier fabrics, you may choose to lengthen the
stitch. (fig. B)
.
Note: 0.75mm is located between the 0 and 1 on both standard &
rolled hem settings.
The stitch width adjusting dial is located above the stitch length dial. (fig.
A) The stitch width displays two sets of numbers, indicating two width
ranges, for overlock stitches. The larger size numbers on the dial, 5.5
through 7.5mm, denote the stitch width when the 0-1 (left) needle is in
use. The smaller size numbers, 3.0 through 5.0mm, apply when only
the 0-2 (right) needle is in use for forming a 3-thread stitch. The "M"
setting (3.5) is for the rolled edge.
Adjusting the stitch width moves the upper cutting blade. It also moves
the stitch fingers further apart or closer together for complete fabric
support with any stitch width.
The stitch width is infinitely variable between either end of the range.
Simply turn the dial aligning the desired setting with the indicator mark
on the machine. Use a wider stitch on loosely woven fabrics. You may
prefer a narrower stitch width on knits, tightly woven, or sheer fabrics.

ifferential Feed
Your Baby Lock serger is equipped with differential feed.The set of
feed dogs work independently in order to ensure smooth sewing on
all fabrics.
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.
When the dial is set above "N" (fig.B), the front feed dog will feed
more fabrics than the back. This is because the front feed dog
moves at a greater distance than the back feed dog. 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. (fig.A)
At the maximum setting of 2 (fig. C), the differential feed can
gather a lightweight fabric to nearly double fullness. (fig. )
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
gathering. 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), add more stretch to swim wear,
active wear, and can be used to create a lettuce edge. (see page 33)

Overlock Thread elivery System
Stitch Selector Lever
Side Cover
The Baby Lock Ovation revolutionizes the way a serger works with its exclusive overlock Thread
elivery System. You no longer have to manually adjust the tension settings for the type of overlock
stitch you are sewing. Select the type of overlock stitch you wish to serge, the Ovation will
automatically feed the correct amount of thread through the needles, the loopers and thread guides
to form a perfect stitch every time.
The stitch selector lever, which controls the overlock thread
delivery system for overlock stitching, is located on the right side of
the machine. Select appropriate setting: A, B, C, or .
A - for overlock stitches using the left needle (O-1) and the looper
threads balanced.
B - for overlock stitches using the right needle (O-2) and the
looper threads balanced.
C - for narrow stitches with a short length and the looper threads
balanced.
- for stitches that require a tight lower looper.
For best results, use setting B or C for WAVE stitching.
See chart on last two pages for stitch selection settings.
Open side door on the left for easy access
to the chain looper thread tray.
Close door before sewing.
Wave/Overlock Selector Lever
The Wave/Overlock Selector lever shows "OVERLOCK" and
"WAVE". Select "OVERLOCK" for overlock stitching. Select
"WAVE" for wave stitching

Chain/Cover Stitch Tension ials
The tension system of the chain and cover stitches are completely separate from the system being
used on the overlock stitches. Unlike the thread delivery system of the overlock stitches, the
tensions of the chain / cover stitch needles and chain looper are adjusted by dials located on the
outer sides of your Ovation.
Chain/Cover Stitch Needle Tension ial
The chain/cover stitch needle tension dial is located on the left upper side of the machine. One
tension dial controls all 3 of the chain/cover stitch needle selections. Normally set at "5", the dial can
be turned from 0 - 9 to increase or decrease the tension on the chain/cover stitch needle threads.
Increase the tension by turning the dial to a larger number.
ecrease the tension by turning the dial to a smaller number.
Align the number with the indicator mark on the front of the machine near the dial.
Chain/Cover Stitch Looper Tension ial
The chain/cover stitch looper tension dial is divided into 2 sections - Chain Stitch and Cover Stitch.
The dial is located on the right upper side of the machine. Align the selected tension setting with the
indicator mark on the front right of the machine.
The Chain Stitch section of the looper tension dial has a tighter looper tension for sewing chain
stitch. Select from the row of stripes on the dial for chain stitching. The wider the stripe the
tighter the chain looper tension.
The Cover Stitch section of the looper tension dial has a looser tension for sewing wide,
narrow or triple cover stitches. Select the solid line on the dial for cover stitch tension settings.
The closer the dial is moved to the wide horizontal mark indicates looser tension for cover
stitching.

Upper and Lower Looper Thread Fine-Tuning Knob
No adjustments are needed when sewing with most fabrics and
threads on your Baby Lock Ovation, but certain threads or
fabrics may require minor fine-tuning of the looper delivery
system to perfect your stitches. Increase or decrease the
delivery of the looper threads with the upper and lower looper
thread fine-tuning knob. With your finger tips, turn the fine-
tuning knob counterclockwise to tighten the looper threads
equally. Turn the knob clockwise to loosen the looper threads
equally.

Sewing Speed Controller
Knee Lifter
Your Baby Lock Ovation is equipped with a sewing
speed controller.
The machine will sew faster with the foot control fully
depressed when the controller is moved to the right and
will sew slower when the controller is moved to the left.
Your Baby Lock Ovation comes equipped with a knee lifter.
Using your knee, the presser foot can easily be raised and lowered; leaving both hands free to
manipulate the fabric.
Align the tabs on the knee lifter with the notches in the jack, and then insert the knee lifter by
pushing it toward the machine until it clicks into place. The black "Knee lifter front cover protector"
should be positioned as shown in the below illustration.
To remove the knee lifter place left hand on the front cover to secure and with right hand pull knee
lifter straight out.

Threading Preparation
When using threads on cones or king spools place the cone or spool
securely over the cone holders furnished on your machine. To avoid
bending the thread stand, you may need to place one hand under the
stand while positioning the cone. The cone holders prevent the cone
or spool from spinning, enabling the thread to feed evenly. (fig.A)
Because threads for the serger feed from the top, standard spool
threads can snag on the rough edges of many of these spools. That's
why spool caps are furnished with your serger to provide a smooth
surface that enables the thread to flow freely. With the spool notch
side down, insert a spool cap into the top of the spool. (fig.B)
When using standard spool threads on your serger, replace the cone
holders with the spool caps with sponge furnished with your machine.
These caps hold smaller spools securely and help the thread to flow
properly. With the spool cap with sponge in place, put the capped
spool on the spindle. (fig.C)
Thread nets may be placed over threads that tend to slip off the
bottom of the spool during sewing. Most threads do not require their
use, but nets often are necessary with nylon, rayon or silk threads
(fig. ). Once it's on the spool, fold the net back on itself. Pull thread
from the top of spool to enable the
thread to feed evenly. (fig.E)
