How Your Serger Operates

E
V

I

E

W

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.

Serging is kind of a knitting process that loops two, three or four threads together to create a stitch.
Your Baby Lock Imagine operates with one or two needles and one or two "loopers," each carrying a
thread to form the overlock stitch.

When fabric is placed into the machine, it reaches the feed dogs first. The feed dogs move the fabric along
as the cutting blades trim the edge, creating a clean edge to be finished. Then the loopers and needle(s)
form the stitch on the fabric edge, supported by one or more parallel "stitch fingers" - Met
keep the fabric flat. The threads become "locked" over the fabric and the resulting stitches encase the raw
edge with thread to prevent fabric raveling.

After setting up your machine for the first time, t
serger is threaded, turn the handwheel - toward you - and watch the movement and operation of the

Needles

Thread

Optional Accessories

Your Baby Lock Imagine serger is set up with 75/11 machine needles, which are suitable for most medium
and lightweight fabrics. For heavyweight fabrics, change to a size 90/14 needle. The needle's semi-ball
point design is suitable for knits and wovens. Some manufacturers' needles may produce better quality
stitches with your Baby Lock than others. For best results, use Organ or Schmetz brand needles - system
HAx1SP/CR, and replace them approximately every third project (see page 46).

All types of thread may be used on your Baby Lock, but 100% long-staple polyester 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 with a minimum amount
of linting.

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 seaming, but they may
be too weak or too fuzzy for the rolled edge. Poor grades of these threads 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, needles and loop­ers. for more information, see page 44 and 45.

Important Note: For maximum performance of the Baby Lock Imagine, it is recommended to use "100%
polyester-long fiber thread". Recommended brands are Maxi-Lock and Metrosene. This thread also per­forms best when used with various decorative threads for serging specialty techniques.

There are optional snap-on specialty feet available for the Imagine.

The optional accessories are available

at your Baby Lock retailer.

After removing the packing materials from the box, gently lift your Baby Lock serger by gasping the handle
provided on the top of the machine. Place the machine on a serger sewing table or any level surface that
provides ample work area to the left of the machine. Place the foot control in a pedal stay, if desired, and
place it under the sewing t
Plug the power cord into the machine first, then into a wall outlet. The power switch is located toward the
back on the right side of the machine. Always make sure the power is OFF when the machine is not in
use (fig.A).

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.
The sewing speed of the machine is determined by the amount of pressure applied to the foot control.
When not in use, do not place anything on the foot control, or the machine could start inadvertently and
the foot control or motor could burn out (fig.A).

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 Imagine Wave to pro­vide a smooth surface that enables the thread to reel off 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 sponge disks furnished with your machine.
These disks hold smaller spools securely and help the thread to reel
off properly

. With the sponge disk in place, put the capped spool on

the spindle (fig.C).
Thread nets may be placed over threads that tend to slip of

f 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.D). Once it's on the spool, fold the net back on itself, if neces­sary, to enable the thread to feed smoothly without snagging on the
net (fig.E).

No adjustments are needed when sewing with most fabrics and
threads on your Baby Lock Imagine Wave, 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
screw. With a screwdriver (found in accessory kit), turn the fine-tun­ing screw clockwise to tighten the looper threads equally. Turn the
screw counter-clockwise to loosen the looper threads equally.

With the needle and upper looper threads under the foot and to
the back, lower the presser foot. While holding the threads in your
left hand, press down on the foot controller gently to begin a
thread chain before serging fabric (fig.A).

You can leave the presser foot down for most serging applications.
Just place the fabric at the toe of the presser foot. As you step on
the foot controller, the feed dogs will begin moving the fabric
toward the needle (fig.B). You need to raise and lower the foot
only when working with thick, spongy or lofty fabrics, or when
precise positioning is required.

Be careful not to push or pull the fabric. The Imagine Wave will
feed it evenly without help. At the end of a seam, just sew off the
fabric edge and continue serging to create 5" - 6" thread chain.
Cut the thread chain with the thread cutter on the left side cover

Clearing the Stitch Width Fingers

As you sew, you will discover that maneuvering the fabric is differ­ent from conventional sewing because the threads form around the
stitch fingers (fig. A).

To clear the stitch fingers, simply raise the presser foot, which
releases all threads. Raise the needle(s). Then pull the threads
gently from behind the foot (fig. B). The stitches are now released
from the fingers (fig. C).

Thread Delivery System

Stitch Selector

Re-threading Needles

Re-threading Loopers

The Baby Lock Imagine revolutionizes the way a serger works with its Thread Delivery System. You no
longer have to manually adjust the tension settings for the type of stitch you are serging. Select the type
of stitch you wish to serge, the Imagine will automatically feed the correct amount of thread through the
loopers and thread guides to form a perfect stitch every time.

The stitch selector controls the thread delivery system and is located on
the right front side of the machine. T

o select a stitch setting, move the
stitch selector lever to A, B, C, or D.
A - For W

ide Overlock Stitches.
B - For Right Needle Wave Stitch, and right needle overlock stitches.
C - For narrow stitches, and Rolled Wave Stitch using right needle.
D - For 3-Thread Rolled Hem stitch.
See chart on last page for stitch selection settings.

If a thread breaks, raise the presser foot and pull the broken thread out from under the foot. Open the
front cover, depress the machine lock button and set the looper threader selector to U or L for the looper
being threaded. Re-thread 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. Refer to page 13 for further information.

Note: When re-threading your Baby Lock Imagine using the "Jet-Air 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 re-threading the machine.

If a needle thread breaks, raise the presser foot, remove the broken thread and rethread the needle thread
guides. Open the front cover, depress the machine lock button. Select the "R" or "L" for the needle being
rethreaded. Use the needle threader for exact and easier threading. Refer to pages 13 for further

information.
