		How Your Serger Operates
	V

ESometimes 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

Vuse. Please read all instructions before using your new machine.

ISerging 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

Eto form the overlock stitch.

Was 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" - Metal prongs that 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, take a few moments to learn how it sews. Before your serger is threaded, turn the handwheel - toward you - and watch the movement and operation of the

various parts. Don't bother with fabric at first. It doesn't hurt your serger to stitch without fabric under the presser foot.When fabric is placed into the machine, it reaches the feed dogs first. The feed dogs move the fabric along

Needles

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).

Thread

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.

RAfter removing the packing materials from the box, gently lift your Baby Lock serger by gasping the han-

Gdle 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,

	E	and place it under the sewing table.
		Plug the power cord into the machine first, then into a wall outlet. The power switch is located toward the
	R	back on the right side of the machine. Always make sure the power is OFF when the machine is not in use
		(fig.A).
		Available foot control for U.S.A.: Model YC-482, or YC-420W
		This appliance has a polarized plug (one blade wider than the other). To reduce the risk of electric shock,
	S	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
	E	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
	T	foot control or motor could burn out (fig.A).
		Raise the telescopic thread guide to its highest position of 14". Rotate the shaft to the left and right until
		each section "clicks" into a locked position (fig.B). The front cover may be opened simply by placing your
		fingers behind the tab at the right side and pulling toward you (fig.C).
	U	To open the cutting blade cover, place your thumb against the tab, and slide the cover to the right. A slight
		pull forward will allow the cover to swing down, providing access to the loopers, blades, and thread guides

Setting Up Your Imagine

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 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

A (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 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.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).

Looper Thread Fine-Tuning Screw

No adjustments are needed when sewing with most fabrics and threads on your Baby Lock Imagine, 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.

Thread Delivery System

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.

Stitch Selector

The stitch selector controls the thread delivery system and is located on the right front side of the machine. To select a stitch setting, move the stitch selector lever to A, B, C, or D.

A - For Wide Overlock Stitches.

B - For Right Needle Stitch, and right needle overlock stitches. C - For narrow stitches, and Rolled Stitch using right needle. D - For 3-Thread Rolled Hem stitch.

See chart on last page for stitch selection settings.

Re-threading Loopers

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.

Re-threading Needles

If a needle thread breaks, raise the presser foot, remove the broken thread and rethread the needle thread guides. Turn the handwheel and line up the green marks on the handwheel and machine. Select the "R" or "L" for the needle being rethreaded. Use the needle threader for exact and easier threading. Refer to pages 12/13 for further information.
