How Your Acclaim 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.

Serging is kind of a knitting process that loops two, three or four threads together to create a stitch. Your Baby Lock Acclaim 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" - 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 counterclockwise 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.

Needles

Thread

Optional Accessories

Your Baby Lock Acclaim serger is set up with 90/14 machine needles, which are suitable for most medium and heavy weight fabrics. For lightweight fabrics, change to a size 75/11 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 (page 55).

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 page 53/54.)

Important Note: For maximum performance of the Baby Lock Acclaim, it is recommended to use "100% polyester-long fiber thread". 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 Acclaim. The optional accessories are available at your Baby Lock retailer.

Setting Up Your Acclaim

L R

C D

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 of the machine. Place the foot control in a pedal stay, if desired, and position it under the sewing table.

2. Plug in the machine

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. Available foot control for U.S.A and CANADA. : Model YC-482. Lay the foot control cord and power cord along the inside of the channel located on the bottom right side of the overlock machine. (fig. B)

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. (fig. A) 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 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.

5. Position the telescopic thread guide.

Raise the telescopic thread guide to its highest position. Rotate the shaft to the left and right until each section "clicks" into a locked position. (fig. C)

6. Opening front cover

The front cover may be opened simply by placing your fingers behind the cover at the upper right side and gently pull toward you. (fig. D)

7. Opening cutting blade cover

To open the cutting blade cover, place your thumb against the tab, and slide the cover to the right. A slight pull toward you will allow the cover to swing down, providing access to the loopers, blades, and thread guides. (fig. E)

Note: The front cover has to be opened before opening the cutting blade cover.

Page 13

O V E R V

When no trimming is desired, as when stitching on a fold, rotate the cutting blade locking dial clockwise to the LOCK position. The cutting blade no longer moves up and down, but remains in its lowered position. To re-engage the cutting blade, turn the cutting blade locking dial half of a turn counter-clockwise. The blade will start moving automatically when you start serging.

Cutting Blade Locking Dial

Thread Cutter

Presser Foot Pressure Adjustment

Snap-On Presser Foot

There is a thread cutter located on the left side of your Acclaim. 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 presser foot pressure adjustment dial on left side of the machine. To increase pressure, turn the pressure adjusting dial counterclockwise. To decrease pressure, turn the dial clockwise.

The Acclaim has the convenience of a snap-on presser foot system.

To Release:

1. Raise the presser foot 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 lever.

2. Lock the cutting blade down.

3. Raise the needles to the highest position.

4. Slide the foot from the left to right.

5. Align the bar of the foot with the groove in the holder.

6. Lower the presser foot lever to snap presser foot into place.

The stitch width adjusting dial is located above the stitch length dial. (fig. A) The stitch width dial displays two sets of numbers, indicating two width ranges. The larger size numbers on the dial, 5.5 through 7.5mm, denote the stitch width when the left needle is in use. The smaller size numbers, 3.0 through 5.0mm, apply when the right needle is in use.

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 variable by the placement of Right and Left needles and the stitch width dial positions. (Fig. B)

The stitch length / rolled hem adjusting dial is conveniently located just to the left of the front 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 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 and rolled settings.

Page 15

O V E R V

Differential 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 dogs. As a result, the fabric becomes compressed or eased, as the diagram on the front cover indicates. This action 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. 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 gathering. Test stitch for desired results.

When the differential feed lever is set below "N" (fig. E), the front feed dog moves less distance than the back feed dog. This adjustment stretches the fabric slightly as it is sewn pulling it taut as it enters the needle area. The lower settings prevent puckers on lightweight fabric (fig. F), add more stretch to swim wear, active wear, and can be used to create a lettuce edge. (page 31)

Upper and Lower Looper Thread Fine-Tuning Knob

No adjustments are needed when sewing with most fabrics and threads on your Baby Lock Acclaim, 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. Turn the finetuning knob counterclockwise to tighten the looper threads equally. Turn the knob clockwise to loosen the looper threads equally.

Thread Delivery System

Stitch Selector Lever

Wave/Overlock Selector Lever

The Wave/Overlock Selector lever shows "OVERLOCK" and "WAVE". Select "OVERLOCK" for overlock stitching. Select "WAVE" for wave stitching.

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 using the left (L) needle. B - For balanced overlock stitches using the right (R) needle and

3-thread Wave stitch. C - For narrow stitches with a short length and Rolled Wave stitch. D - For 3-Thread rolled hem stitch.

For best results, use setting B or C for WAVE stitching. See chart on last page for stitch selection settings.

The Baby Lock Acclaim 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 Acclaim will automatically feed the correct amount of thread through the loopers and thread guides to form a perfect stitch every time.

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 Acclaim 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 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)

Threading Your Acclaim

Threading Lever Position for Threading

Lower Looper

Threading Lever

Your Baby Lock Acclaim is equipped with an exclusive "Electronic RevolutionAir Threading System" for fast, easy threading of the upper and lower loopers. One touch of the "Push to Thread" buttons will automatically thread the loopers and needles. It is no longer necessary to use tweezers for threading the loopers or needles. If a looper thread breaks or runs out, just re-thread it. There is no need to follow a specific threading sequence.

1. Open the front cover.

2. Raise the presser foot to release all threads.

3. Set the threading lever from serging position to threading position. (fig. A)

4. Rotate the machine handwheel slowly toward you until the tubes move to their connecting position. (fig. B)

Note: The Acclaim must be in the locked threading position when threading the loopers and needles, unless otherwise indicated.

1. With the presser foot up and threading lever in the threading position. ( fig. A)

2. Place the thread cone or spool on the far right spool pin on the thread stand. (fig. C page 19) Slip

the thread into the telescopic antenna thread guide "1" directly above the spool, snap into the pretension thread guide "2" at the top of the machine, then through the slot on the front of the machine. (fig. C page 19)

3. Pull 18 inches (45cm) of thread through guide "3". (fig.C, page 19) Insert the end of the thread

into the threading port "L" about 1/2 inch (1,2cm) . Use tweezers if necessary, to insert the thread end more easily.

4. Push the threading button (fig. D page 18) . If the thread does not go through the lower looper eye

with one push, push the threading button again until it does. *(page 19)

5. Clip the thread 4 inches (10cm) from the lower looper eye and leave it hanging loose inside the

machine.

6. Once machine is completely threaded for chosen serging application, set the threading lever to

the serging position.

Serging with fabric

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. Turn the handwheel counterclockwise to 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)

With the needle and 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 control 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 under the toe of the presser foot. As you step on the foot control, 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 Acclaim 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. (fig. C)

Note: The raised markings on the toe of the presser foot are seam line guides. They indicate the needle positions to help guide your fabric for accurate seaming.

Re-threading Needles

Re-threading Loopers

If a needle thread breaks, raise the presser foot, remove the broken thread and rethread the needle thread guides. Use the "RevolutionAir Threading" feature for quick and easier threading. Refer to pages 21 or 22 for further information.

If a thread breaks, raise the presser foot and pull the broken thread out from under the foot. Open the front cover and engage the threading lever. (page 18) Re-thread the machine above the threading port, leaving an 18-inch (45cm) thread tail. Thread the looper as usual then engage the threading lever to the serging position. (page 18/19) Close the front cover and sew a test sample.

Note: When re-threading your Baby Lock Acclaim using the "RevolutionAir 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.

Overedging to finish facings, hems and seams before construction, is one of the most basic uses of a serger, such as making a garment or project with 5/8 inch (16mm) pressed open seams. (fig. A)

To overedge, place the single layer of fabric in front of the presser foot, aligning the cut edge with upper cutting blade. Begin sewing, continuing to guide the fabric along the blade. The edge of the fabric should be trimmed, but not cut away. Then sew the seams on your conventional sewing machine and press them open as usual. (fig. B)

Because notches would be cut away in this process, mark them before sewing with "V" snips just inside the seam allowance or with a water-soluble fabric marker. (fig. C)

Note: A 2-thread overlock or 3-thread overlock can also be used with this technique.

4-Thread Overedging

Overlock Seam

For garments or projects that do not require conventional pressed-open seams, you can stitch and finish the seam in one operation and then press the seams to one side. (fig. A) A 4 or 3-thread seam is strong, yet it provides "give" or flexibility according to the needs of the fabric.

Place two layers of fabric right sides together. Use the marks on your serger's front cover to align the fabric for the desired seam width. Keep your eye on the fabric edge to guide it to the appropriate mark. (fig. B)

Do not watch the needle. If you guide the fabric accurately, the needle will seam in the correct place automatically.

Note: For most seaming, pins are unnecessary because the serger feeds the fabric evenly. If you need pins, place the pins parallel to the seam line outside the seam allowance to avoid damaging the blades.

4-Thread Overlock

With the Acclaim Thread Delivery System, the upper and lower looper threads lock together evenly over the cut fabric edge(s) to form a flat, non-rolling pattern of overlocking stitches on both sides of the fabric.

The left needle thread interlocks with both looper threads at the stitching line to create the seam. The right needle thread, visible on the top side of the stitch, interlocks with both the loopers to add durability. The thread, that resembles a zigzag on the upper side of the fabric, is from the upper looper. The thread, that resembles a zig zag on the lower side of the fabric, is from the lower looper.

Move the stitch selector lever to "A".

For the perfect 4-thread overlock stitch, follow the suggested settings and threading diagram below.

3-Thread Overlock-Wide

The 3-thread overlock wide stitch is perfect for edge-finishing most woven fabrics and for seaming knits that do not require the extra durability that a fourth thread provides.

It's easy to convert your Acclaim to serge with 3 threads by simply eliminating either needle.

To convert your serger to a 3-thread overlock wide (7.5mm), cut the right needle thread just above the needle eye. (fig. A) Remove the right needle and right needle thread completely from the machine. Re-tighten the needle clamp screw slightly to prevent the screw from working out. (fig. B)

Note: Do not tighten needle clamp screw(s) without needle being inserted within the slot.

Lettuce Edge

Belt Loops and Button Loops

Returning to Standard Serging

Use the rolled edge thread chain, stitched without fabric, to make professional belt loops and button loops. Using a heavy decorative thread in the upper looper forms a stronger loop.

Clear the stitch fingers and return the stitch length dial to the standard range. Set stitch width and length at the desired settings. Replace the left needle and its corresponding thread, if desired.

A frilly or "lettuce" edge can be created on most light and medium weight stretch fabrics and on bias edges of soft, woven fabrics. It makes a pretty decorative edging for activewear, lingerie, accessories and children's wear.

Set the machine for the 3-thread rolled edge. (page 30)

Set differential feed at 0.6. (fig. B) Serge the fabric in the direction of greatest stretch - the crossgrain on knits, bias grain on wovens. For a "leafier" effect, try using a shorter stitch length and gently stretch the fabric as it is being sewn. Sew a test sample. (fig. C)

Use the 3-thread rolled hem setting when sewing sheer fabrics that otherwise would require French seams. Set the stitch length at 2.5. Then simply sew the seams, aligning the fabric edges with the serger seam guide, trimming away the excess seam allowance.

Seaming Sheers

Flatlock seams are most suited to fabrics which do not ravel such as interlock knits, tricot, sweatshirt fleece and synthetic suede. The needle thread is carried below the fabric and to the cut edge of the fabric. The lower looper thread rides along the cut edge of the fabric for stability. The edges pull open and flatten within the stitch for a non-bulky join. Be sure to sew a test sample first to determine whether the stitch will have the strength to hold the seam without the fabric pulling away.

Move the stitch selector lever to "D".

2-Thread Overlock

The 2-thread function provides an economical and less bulky means of overedging all fabrics. The standard 2-thread overlock is the same as a 2-thread flatlock stitch. When sewn with specialty threads, 2-thread sewing makes decorative seams and edges for activewear, children's clothing , ruffles, and hemlines.

Converting from 3-Thread to 2-Thread Overlock

Page 37

Sew 2-thread flatlock seams in the same way as 3-thread flatlock seams, then pull the two fabric layers apart until the seam lies flat. (fig. A) Because the threads show on the outside as well as the inside of the garment or project, the 2-thread flatlock seam is often considered a decorative application. (fig. B) Be sure to sew a test sample first to determine whether the stitch will have the strength to hold the seam without the fabric pulling away.

For 2-thread flatlock - wide

1. Engage the threading lever in the threading position.

2. Place the needle thread on far left spool pin.

3. Thread needle thread through the upper looper pretension thread guide on top of the machine, then go down the thread path in the front of the machine. Go left with the needle thread at the hook on front of the machine. Then take the needle thread through the normal needle thread paths. (illustration below). Thread the left needle for a wide flatlock.

4. Turn the cutting blade to the "LOCK" position .

5. Engage the subsidiary looper following step 3 on page 33.

6. Thread the lower looper as shown in the illustration below.

7. Engage the threading lever in the serging position.

For "loops" (lower looper thread) to show on the right side, place fabric wrong sides together for sewing the seam. To produce the "ladder" (needle thread) on the outside, place the fabric right sides together. (fig. B)

Flatlock "Topstitching"

The flatlock stitch need not be limited at seamlines. When sewn on a fold, flatlocking can create attractive decorative effects within the body of a garment or project. Either follow placement lines on your pattern or design your own special effects by stitching the fabric before laying out pattern pieces.

1. Set the machine for 2-thread flatlock - wide.

2. Turn the cutting blade locking dial clockwise to disengage the upper cutting blade.

3. Set the stitch length to desired setting appropriate for the thickness of your decorative thread.

4. Fold the fabric (right side or wrong side out, depending on the loop or ladder (page 35) stitch you want to show) along stitch placement lines.

5. Position the fabric under the presser foot, aligning the fold of the fabric 1/8 inch (3.5mm) to the left of the upper cutting blade. (fig. A)

6. Stitch to the desired ending point.

7. Clear the stitch fingers and chain off the fabric. (fig. B)

8. Clip threads, leaving a 3-4 inch (7.5-10cm) chain.

9. Gently pull the fabric to flatten the stitches. (fig. C)

10.Separate the chain threads and thread them through a hand sewing needle and pull them to the fabric back side. If necessary, tie a knot to secure the threads. (fig. D)

Note: If the fabric does not pull completely flat under the stitches, guide the fabric fold to the left so that the loops hang slightly off the fold as they are being stitched.

Blind Hemming

Your Baby Lock Acclaim can create a sturdy, nearly invisible blindhem.

1. Set the machine for 2-Thread Overlock-Narrow with the right needle threaded. Set the stitch width at 5.0 and the stitch length at 4.0 in the standard range.

2. Fold up the hemline and press it in place. Then fold the hem allowance back against the fabric right side to create a fold about 1/4 " from the top edge of the hem as shown (fig. A).

3. Align the fold under the presser foot and stitch, allowing the needle to catch only a thread or two of the soft fold. (fig. B) The blade will trim the top edge of the hem and the loopers will overcast the edge for a clean finish. (fig. B)

4. Open the fold and press flat. (fig. C)

Note: An optional blindhem foot for consistent guiding is available through your Baby Lock retailer. (fig. D)

Wave Stitch

The Wave Stitch provides a decorative "wavy" edging on fabric. (This is not to be confused with "Lettuce Edge" on page 31). The upper looper thread and the lower looper thread gradually appear every 25 stitches to create a stitch that looks like a "Wave". When using different color specialty threads (pages 53/54) for the upper or lower loopers, the Wave stitch creates an attractive stitch for edging. When combining decorative threads for the Wave stitch, please sew test on a sample of the fabric you will be sewing on before applying the Wave stitch to your garment. For best results, heavier decorative threads should be limited to the upper or lower looper at one time. Not both upper looper and lower looper at the same time. Wooly nylon in the corresponding looper and serger sewing thread in the right needle will make a striking combination with the heavy decorative thread.

Converting from Normal Serging to Wave

1. Turn the Wave/Overlock Selector lever from "OVERLOCK to "WAVE".

2. Cut the threads from the thread cones and remove from the thread paths.

3. Engage the threading lever to the threading position. (page 18)

4. Place the right needle thread cone on the second spool pin on left.

5. Slip the right needle thread into the telescopic thread guide directly above the thread. Follow the left needle threading path down to the right needle.

6. Thread the right needle using the needle threader. (page 21)

7. Place the upper looper thread cone on the second from right spool pin.

8. Slip the upper looper thread into the telescopic thread guide directly above the thread. Follow the top threading path for the right needle thread, down the front threading path, through the chrome thread guide, and directly to the "U" threading port for the upper looper. Thread the upper looper. (page19)

9. Place the right needle thread and upper looper thread under the presser foot and to the back.

10. Place the lower looper thread cone on the first spool pin on right.

11. Thread lower looper using the standard lower looper threading technique. (page18)

12. Engage the threading lever to serging position.

13. Set Stitch Selector on "B" for Wave Stitch or "C" for Rolled Wave Stitch (page 42-44 for suggested settings).

14. Set Stitch Length and Stitch Width following the suggested settings on page 42-44.

Note: Recommended settings will vary depending on thread type and fabric.

Securing Ends

The serger stitch will not unravel readily, and in most cases serged seams are secured by an intersecting seam. If that's not the case, there are several options for securing a seam. (fig. A)

1. Leave a 3 inch (7.5cm) chain, separate the threads and tie a knot.

2. Apply a dot of seam sealant on the thread chain at the fabric edge. Allow to dry and cut off the excess thread chain.

3. Leave a 3-4 inch (7.5-10cm) thread chain and use a large-eye tapestry needle or double-eye needle to weave the chain back into the stitching.

4. Lock the beginning or end of a seam by serging over the previous stitches.

To lock the beginning of the seam:

1. Manually turn the handwheel toward you taking 2-3 stitches into the fabric. Leave the needle(s) in the lowest position to anchor the fabric.

2. Raise the presser foot.

3. Smooth out the thread chain with your fingers. (fig. B) Then bring the chain around and under the foot, so that it aligns with the edge of the fabric. (fig. C)

4. Lower the foot and continue sewing, catching the thread chain in the stitches for about 1inch (2.5cm). Let the blades cut off any remaining thread chain (fig. D-E).

Securing Ends (Cont.)

To lock the end of the seam:

1. Take one stitch off the end of the seam. (fig. F)

2. Raise the presser foot and bring the needle(s) to the highest position. Pull back gently on the fabric to clear the stitch fingers.

3. Turn the fabric over with the wrong side of the stitch facing up (fig. G), and reposition it under the presser foot with the needle at the seam edge, aligned with the previous needle line. (fig. H)

4. Lower presser foot and sew 5-6 stitches over the previous stitches, being careful not to cut them. You may want to turn the cutting blade locking dial clockwise to the lock position. Pivot the fabric and chain off. (fig. I-J)

Turning Outside Corners

Turning Inside Corners

1. Stitch along one edge until you reach the corner. Take one stitch off the edge of the fabric (fig. A).

(As you approach the edge, you may want to stop and

manually turn the handwheel towards you.)

2. Raise the needle(s) to the highest position.

3. Clear the stitch fingers, and rotate the fabric to reposition the needle at the previous row of stitching. (fig. B) Gently pull up on all threads to remove slack and resume stitching. (fig. C)

Note: A loose thread loop at the corner is caused by too much slack in the needle thread when clearing the stitch fingers. Try again, turning corners takes a little practice!

1. Reinforce loosely woven fabrics at the corner with staystitching on the conventional sewing machine. Clip to the corner. (fig. A)

2. Align the fabric edge with the blade, and stitch until the blade reaches the corner, not the needles. Don't cut into the corner. (fig. B)

3. Lower the needle(s) to anchor the fabric.

4. Raise the presser foot and straighten out the fabric edge, forming a fabric pleat at the corner. (fig. C)

5. Be sure the marked stitching line is straight, then continue serging the remaining edge. When done correctly, the pleat will disappear after stitching. (fig. D)

Serging Curves

Inserting Tapes

To serge around inside or outside curves, guide the fabric into the cutting blade, not the needle(s). Remember, cutting takes place before the fabric reaches the needle. Because the long serger

presser foot holds the fabric more securely, you may need to raise and lower the presser foot several times to maneuver around very tight curves.

The slots in the standard presser foot are designed to guide stabilizing tape, narrow elastic or decorative ribbon into the stitching. Insert tape, elastic or ribbon into the slot and under the back of

the foot. (fig. A) Adjust the stitch width to match the tape width. Place the fabric under the foot and stitch. (fig. B)

Cutting Blade Cover Seam Guide

Use the marks on the cutting blade cover and set the width dial at "M" to align the fabric for accurate seam allowances. When using the left needle, the second mark "L" from the needle indicate 5/8 inch (16mm) from the cutting edge to the needle. Use the right needle and the third mark "R" from the needle to indicate 5/8 inch (16mm) from the cutting edge to the needle.

Note: Be sure to set the width dial at the "M" setting for accurate seam allowances.

Page 52

Threading Medium Weight Thread

Medium weight threads, including topstitching thread, Decor rayon and stretch nylon thread, are too bulky to form a knot that would fit through the threading port, but they can slip through the hole with the aid of a thread "cradle" made from regular serger thread (page 51).

Using Specialty Threads

Threading Lightweight Thread

Changing Threads

Beautiful stitches can be formed by serging with specialty threads, cords and ribbons. These heavier or shinier threads can be used to enhance appearance, add strength or elasticity, or create special effects, depending on the thread you choose.

Some specialty threads work well through the needle and loopers. There are some that are too heavy for the needle and should only be used in the loopers.

Use the Specialty Thread chart on pages 53/54 as a guide keeping in mind that the threads can vary from one manufacturer to another. It is best to sew test for best results.

Note: Thicker threads require longer stitch length.

Specialty thread used in the needle can be threaded in the usual way. The ease with which they can be threaded in the loopers, however, depends on thread thickness.

1. Clip the existing thread at the cone and remove the cone from the spindle. (fig. A)

2. Place the new cone on the spindle. With the two threads together, tie an overhand knot or square knot. (fig. B)

3. Raise the presser foot, and pull the old thread from under the foot until the new thread comes through the machine.

Note: When changing a needle thread, pull the thread through until it reaches the needle eye. Then clip off the knot (fig. C) and rethread the needle eye manually or with the needle threader.

Bypassing the Threading Port

Heavy weight threads can be used through your regular 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 and cutting blade covers and then raise the presser foot.

2. Just above the threading port, clip the looper thread to be replaced. Pull the thread out of the upper guides and remove the cone.

3. Place the specialty thread on the spool pin. Thread it into the upper guides and clip it a couple of inches beyond the base plate. (fig. A)

4. With machine engaged in the serging position, hold the thread end at the looper eye and use the tweezers to pull the existing looper thread out of tube extending from the threading mechanism. (fig. B) Leave the thread in the tubular looper.

5. Tie the specialty thread onto the regular thread with an overhand knot. (fig. C) Pull on the regular thread from the looper eye until the specialty thread comes through the looper eye.

6. Place upper looper thread under the foot and to the left: clip lower looper thread at the base plate.

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 51) to make a thread cradle. Then:

1. Engage in the serging position.

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 inch (5cm) of your decorative thread into the cradle loop. Pull on the loose ends of the thread cradle from the looper eye until the specialty thread comes through the looper eye.

Thread Cradle for Loopers

1. Open the covers, and then raise the presser foot.

2. At the threading port, clip the looper thread that is to be replaced. (fig. A) Remove thread from under the foot and the upper thread guides. Replace cone of thread with specialty thread.

3. With the threading lever engaged in the threading position (fig. B) turn handwheel towards you to close looper tubes. (fig. C)

4. Thread specialty thread into the upper thread guides, leaving an 18 inch (40cm) tail above the threading port. (fig. D)

5. Cut a 24 inch (55cm) strand of serger thread and fold in half to form a thread cradle. Insert the loose ends of the thread cradle into the port about 1 inch (2.5cm).

6. Holding the cradle loop with your left hand, depress the "Push to Thread" Button with your right hand (fig.E) until the thread ends come out the looper eye. For chain looper, open side door of machine to make sure thread is in eye of chain looper.

7. Insert the specialty thread tail into the cradle loop (fig. F), pull the serger thread ends until the specialty thread comes through the looper eye. (fig. G) Discard or set aside the thread cradle.

8. Place upper looper thread under the foot and to the left, cut lower looper thread to 4 inches (10cm) and leave it hanging loose.

Looper Threading Tool

1. Open the front and cutting blade covers, and then raise the presser foot.

2. At the threading port, cut the looper thread that is to be replaced. Remove thread from under the foot and the upper thread guides. Replace cone of thread with specialty thread.

3. With machine engaged in threading position.

4. Thread specialty thread into the upper thread guides, leaving an 18 inch (45cm) 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.

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. (fig. B)

Cleaning

Replacing LED Lighting

Your Baby Lock will operate at best performance if it is kept clean at all times. The serger's cutting action creates much more lint than you will find on conventional sewing machine.

Your serger's major moving parts are well protected and do not need to be oiled. However, we recommend that you use the cleaning brush often during garment construction in order to keep lint off the blades, the needle bar, the feed dog mechanism and loopers. If machine needs to be oiled, check with your nearest Baby Lock retailer for use of high grade recommended sewing machine oil.

TO REMOVE NEEDLE PLATE PROCEED AS FOLLOW:

1. For safety reasons, unplug main power cord.

2. Raise and remove presser foot.

3. Select stitch length dial to rolled hem setting.

4. Remove needles from needle clamp.

5. Turn your handwheel until the upper looper is in the far right position.

6. To remove the needle plate, remove front screw with screwdriver and back screw with Allen wrench. (fig. A)

7. With your right hand, first raise the needle plate in front of the blade. Pull slightly to the right, then remove to the left.

8. Replace in reverse procedure.

9. Finally, position the needle plate so that the needles lower in the center of each hole on the needle plate. (fig.B) Then tighten both screws.

Your Baby Lock Acclaim is equipped with long-life LED lighting system, which is not necessary to change bulbs. In case of replacing LED unit, please contact your authorized Baby Lock retailer.

Dos and Don'ts

Needle threading difficulties:

1. Is the thread end in the proper needle eye?

2. Is the thread end cut sharp?

3. Is the needle threading lever down completely?

4. Is the needle threading inlet just behind the needles?

5. Is the needle bent or worn?

6. Is the needle inserted correctly?

Looper threading difficulties:

1. Is the machine engaged in the threading position?

2. Is the thread end in the proper threading port?

3. Is at least 1/2 inch (1.2cm) of the thread end in the threading port?

4. Is there at least 22 inches (56cm) of loose thread beyond the thread guide above the threading port?

5. Is there a kink or twist in the 22 inch (56cm) of thread to restrict the flow into the threading port?

6. Is the thread restricted from going through the loopers?

Poor Cutting:

1. Are the cutting blade(s) dull?

2. Have you sewn over a straight pin?

3. Is the cutting blade in the locked position?

4. Have the cutting blades been improperly replaced?

5. Is the fabric being pulled from the rear of the machine while sewing?

Wave Stitch is not forming correctly:

1. Is the machine threaded correctly? Check each thread path carefully.

2. Is the machine set for 3-Thread Wave sewing?

3. Is the Wave/Overlock Selector Lever set on "WAVE"?

4. For rolled wave edging, is the stitch length dial set for "ROLLED HEM" ?

5. Is the Stitch Selector set correctly? Set the Stitch Selector at "B" for 3-Thread Wave Stitch or "C" for 3-Thread Rolled Wave Stitch.

1. Always be aware of the needle's up-and-down movement, and do not turn your attention from the machine while it is running.

2. When changing the needle, the presser foot or any other parts, always disconnect the machine by turning the power switch to OFF.

3. Do not place anything on the foot control, or the machine will start inadvertently and the foot control or motor can burn out.

4. When using your serger for the first time, place a fabric scrap under the presser foot and run the machine without thread for a few minutes. Wipe away any oil that appears.

5. Do not pull fabric from the rear of the machine. Such action can damage the machine.

6. To prevent possible injury, always avoid body contact with any moving parts and the machine mechanism.

7. NEVER sew over pins.

Special Caution: Unplug the power cord from the electrical outlet when the machine is not in use.
