Machine cover The machine cover protects your machine from dust and dirt. When you have finished sewing, push the thread guides (28 and 44) down. The thread stand (49) must be pushed as far as it will go towards close to the machine; you can take the thread cones off first, but this is not essential. Now you can pull the 4874 cover over the machine. The operator’s manual and accessories can be placed in the pockets.
Technical section, general Swivel table Push the swivel table (21) to the left. The converter, the tweezers and the allen key are located behind the swivel table. Front cover Push the front cover (16) to the right as far as it will go and swing it down. The top/deco cover sewing program sticker is behind the front cover. The 5 most important stitch types and their threading paths are illustrated in color on the inside of the front cover.
Note: The detachable thread stand is required for stitch programs 21 – 30. Detachable thread stand Insert the top catches of the detachable thread stand (27) into the top slots on the rear cover and press the bottom portion of the stand against the cover. Push the detachable thread stand to the right as far as it will go. Place one foam pad (52) and one cone holder (51) on each of the spool pins (50). To remove, push the thread stand to the left and pull up.
Technical section, general Foam pads/Cone holders If you are using large cones (5,000 – 10,000 mm), the foam pads (52) and the cone holders (51) will be helpful to you. With synthetic threads, the foam pads catch threads that have slipped down and help to advance the thread flawlessly. Cone holders serve to ensure that large cones are well positioned. Thread run-off disc The thread run-off disc in the accessory box is used for smaller spools. Use the foam pads (52) and place the spool on the pin (50).
Hand wheel When turning the hand wheel (56) by hand, e.g. to raise the needle(s) to their highest position, always turn toward you. Presser foot lift Use the presser foot lifter (57) to raise or lower the presser foot. If you push the lifter one step up, you will be able to raise the presser foot to its maximum height of 6.5 mm for particularly thick fabrics.
Technical section, general Presser foot The standard presser foot has two different positions: Note: The position of the presser foot, “A” or “B”, appears in the LCD display (9) (see page 3-2). Position “A” - for sewing cover stitch (progs. 1, 2, 3), double chainstitch (prog. 4), the 4-thread safety seam (prog. 19) and the 5-thread safety seam (prog. 20). Position “B” - for sewing programs 05 – 18. To choose these positions, simply move the selection lever. 20 For cover stitch (progs.
Needle position The 4874 offers a choice of 5 needle positions. You can sew with as many as 3 needles simultaneously. The needle positions are L0, L1, L2, R1 and R2. A retaining screw is provided above each needle. Note: If the needles are inserted at R2 and R1, the left needle is slightly higher than the right. R1 R2 In this operator’s manual and in the LCD display (9) (see page 3-2), the different needle positions are shown in a schematic diagram. See the examples at top and bottom.
Technical section, general Changing a needle Turn off at the power switch To remove: Lower the presser foot and raise the needle(s) to its/their highest position. Take the needle changing tool out of the accessory box and push it up over the needle as far as it will go. Loosen (but do not remove) the needle’s retaining screw with the allen key and pull the needle out from below.
Threading (stitch programs 01-20) Thread guides Slide the thread stand (49) backwards and pull the thread guide (44) up as far as it will go. Place the spools on the spool pins (50). For notes on the spool net, the thread run-off disc, the foam pads and the cone holders, please see page 2-5. Thread the threads from the back to the front through the thread guides (43) as indicated by the color codes. Lift the carrying handle (3).

Technical section, general Speed control With the speedcontrol slider (8), you can set the maximum speed to any value from 700 rpm to 1500 rpm. If you select programs 21 – 30, the maximum speed is reduced to 400 rpm. Presser foot pressure The preset presser foot pressure on the machine is suitable for medium fabrics. For most fabrics, the presser foot pressure does not need to be altered. Note: Lower the presser foot before turning the presser foot pressure adjustment knob.
Thread cutter At the end of a seam, sew a thread chain of 15 to 20 cm (7”-10”) and pull the thread chain from back to front over the thread cutter (47). This will cut off the thread chain. Check spring for edging the thread chain Use the check spring for edging the thread chain (37) to edge the thread chain at the start of the seam. To do this, sew a thread chain at least 10 cm long before you begin the seam. Raise the presser foot and pull the thread chain carefully away from the stitch finger (32).
Technical section, general Disengage the upper knife Turn off the power switch Remove the trim catcher and open the front cover and the swivel table. Raise the upper knife (35) to its highest position by turning the hand wheel. Now push the knob for lowering the upper knife (39) as far as it will go to the right. Turn the knob towards you until the upper knife is seated in its lowest position. The upper knife is now disengaged.
Stitch finger For Standard Overlock Seams: For sewing all standard overlock seams (ex. progs. 01-04 and 21-30) the stitch finger (32) remains in its engaged position. 32 For rolled hems Remove the trim catcher and open the front cover. Pull knob A of the stitch finger (32) to the right and swing it down into its disengaged position. A Note: The position of the stitch finger will be shown in the LCD display (9) (see page 3-2). 2-28 You can sew all rolled hems with this setting.
Technical section, general Attach converter Turn off the power switch The converter (41) must be attached for all 2-thread seams (except program 04) and the 2-needle, 3-thread overedge seam. Open the swivel table and take out the converter. 41 30 Move the upper looper (30) beside and to the right of the needle by turning the hand wheel. Secure the tip of the converter in the eye of the upper looper and push the converter onto the upper looper base.
Disengage the upper looper You can disengage the upper looper (30) with the upper looper disconnection lever (18). Remove the trim catcher and open the front cover. Turn the hand wheel to bring the looper to its lowest position. Note: The LCD display (9) will show whether the upper looper should be attached (see page 3-2). Press the upper looper disconnection lever (18) down and push it to the left. Turn the hand wheel to ensure that the looper is indeed disengaged.
Technical section, general Remove knife guard Remove the trim catcher and open the front cover. Pull the knife guard (17) up and off. To insert, place the knife guard under latch A and push down into the front cover guides. A Note: The sewing table (accessory) is attached in the same way.
Set seam width Turn the seam width adjustment knob (22) to select any seam width value from 3.5 to 6.0 mm; it will also be displayed in the viewing window (23). (Double chain stitch is sewn with a gap of 6.5 to 9 mm.) Figure A: If loops are protruding from the edge of your seam, turn the seam width selection knob upwards to shift the upper knife (35) to the right. Figure B: If your seam puckers at the edge, turn the seam width selection knob downwards to shift the upper knife (35) to the left.
Technical section, general Setting the stitch length The stitch length is selected automatically by the creative 4874. However, it can be changed and stored at any time using stitch length adjustment buttons (14) (see page 3-4).
Note: The effect of the differential feed also depends on the stitch length selected and the type of fabric being used. Differential feed The differential feed consists of two feed dogs arranged one behind the other. Both feed dogs (A + B) move the fabric. The movement of the front feed dog (A) can be regulated using the differential feed adjustment buttons (15). The setting range is from 0.5 to 2. This setting regulates the amount of material being fed by the front feed dog.
Technical section, general If you set the differential feed to 2.0 the front feed dog moves at twice the speed of the rear feed dog. This means that the front feed dog moves twice as much fabric as the rear feed dog. This gathers the fabric. In this way, you can prevent the seam from stretching when you work with knits such as jersey or cable knits. The seam will remain flat (A). A However, you can also use it to achieve fashionable effects such as the gathered effect with very fine fabrics (B).

Important notes on sewing with the top cover stitch Sewing table The sewing table is marked with various measurement units. The figures at the top are centimeters, those at the bottom represent inches. Preparing your project If you are going to use top cover stitches for decorative effects, you can mark the outlines on the right side of the fabric with textile pen or chalk, and sew along these lines. Test your textile pen with your fabric.
Top Cover Stitch Stopping sewing 1. If you are sewing to the edge of the project: Grasp the threads at the end of the seam and sew slowly off the project. As you do so, pull the threads gently backwards. 2. If you are sewing a continuous hem (around a project): Sew 4–5 stitches over the previous stitches. On the last stitch, turn the hand wheel towards you slowly until the needles reach their lowest position. Now turn the hand wheel back until the needles are in their highest position.

Deco Cover Deco Cover In this chapter, we are going to describe the basic functioning of your creative 4874 using the example of the deco cover stitch.
Deco Cover Switching the machine to deco cover operation (progs. 24 - 30) Detachable thread stand For deco cover sewing you need to use the detachable thread stand. Insert the top catches of the thread stand (27) into the top slots on the rear cover and press the bottom portion of the stand against the cover. Push the detachable thread stand to the right as far as it will go. Place one foam pad (52) on each spool pin (50). To remove, push the thread stand to the left and pull upwards.
Deco Cover Top/deco switch lever Choose a stitch program and move the top/ deco switch lever A to the correct position: Right for top cover, programs 21, 22 and 23 Note: If the top/deco switch lever is not in the correct position, the machine will not run in programs 21 – 30 and an alarm will sound. Left for deco cover, programs 24 – 30 A For our example, we have chosen program 27.
0 1 L 2 1R 2 With the needle changing tool, insert needles L 0, 1 and 2 as far as they will go into the needle holder (make sure the needles are inserted all the way with your fingers). Tighten the associated retaining screw and remove the needle changing tool. Pull knob A of the stitch finger (32) to the right and swing it down into its disengaged position. A Turn the hand wheel to bring the upper looper to its lowest position. Press the lever (18) down and push it to the left.
Deco Cover Raise the upper knife (32) to its highest position by turning the hand wheel. Now push the knob for lowering the upper knife (36) as far as it will go to the right. Turn the knob towards you until the upper knife is in its lowest position. The upper knife is now disengaged. 3,5 Turn the seam width selection knob (22) to set the seam width to 3.5 mm. R Use clearview foot R from the accessory box. The machine is now set for thicker thread for use with the decorative thread guides.
Accessories The following accessories are provided for deco cover: 1. Blue decorative thread guide 2. Yellow decorative thread guide Both decorative thread guides have three holes for threading the decorative threads. This is indicated on the stitch program . sticker by the following symbol: This symbol indicates which of the holes to insert the thread, and which of the two thread tensions (blue/yellow) you must use.
Deco Cover To remove the decorative thread guides, loosen the screws with the allen key. Place the screwdriver between the decorative thread guide and the holder and press the tip of the screwdriver gently forwards. The thread guide will pop out of the holder. Remove the blue one first, and then the yellow one. When you press the memory selection button P once, the program memory opens. The thread tension values appear beside the program number in the display.
Thread the threads in order from 1 to 10. Thread guide 8 is marked with a purple square. 1 2 3 10 7 6 5 9 8 Note: In the case of thread guides 6 and 7, the thread is simply placed on top of them, not threaded through. 4 Thread the thread in the guides from 1 to 8. (Make sure the thread does not pass under the latch.) 8 7 6 4 5 Note: The lever will return to its original position as soon as you start to sew. Press lever A up and hook the thread into slot B.
Deco Cover Pull about 10 cm (5”) of thread through the looper and place it to the left under the presser foot. Threading the needle(s) Thread the threads in order from 1 to 9. 1 2 5 3 4 6 7 8 9 The thread must pass through the lower slot in thread guide 5. To thread needles more easily, use the needle threader in the accessory box.
Deco-cover thread tension dials, blue and yellow Set the deco cover thread tensions, blue and yellow (45) as indicated on the stitch program sticker. To do this, turn the thread tension dials until the corresponding settings appear directly above line A and line B. A Threading the deco cover threads Place the spools on the corresponding spool pins (1 x blue, 1 x yellow) of the detachable thread stand. Thread the corresponding color coded thread guides from the back forwards.
Deco Cover Now guide the thread into the color coded thread guide in the detachable thread stand. Thread the deco cover threads in order through 1 to 4 and bring them behind the needles. With tweezers, turn them to the front towards you. 1 Some of the thread guides are marked in blue and yellow.

Deco Cover Stitch program 30 10-thread deco cover Important notes on sewing with the Deco Cover Stitch Sewing table The sewing table is marked with various measurement units. The figures at the top are centimeters, those at the bottom represent inches. Preparing your project If you are going to use deco cover stitches for decorative effects, you can mark the outlines on the right side of the fabric with a textile pen or chalk, and sew along these lines. Test your textile pen with your fabric.
Note: Test sew the cover stitch first, without adding the deco cover thread. When the stitch is tested, continue sewing also with the deco cover thread. Starting to sew Lift up the presser foot and position the fabric under the presser foot so that the needles pierce the fabric on the first stitch. The deco cover threads must be behind the needles in order to be picked up on the very first stitch. The raw edge must be along the two of the sewing table. Keep the threads moderately taut and start sewing slowly.
Deco Cover Raise the presser foot. Grasp the threads at the end of the seam and press the tension release button to pull the project out. Cut the threads off. Pull the deco cover threads through to the wrong side of the fabric and tie off.
Stitch formation Since deco cover consists of a combination of cover stitch with deco cover threads, we will present suggestions for adjustment with reference to cover-stitch. 5-thread deco-cover, program 24 If all the thread tensions are set correctly, the needle threads (blue and green) are almost invisible on the underside of the fabric. The looper thread (purple) lies slack between them. The deco cover threads (blue and yellow) are lying slack between the needle threads on the top side of the fabric.
Deco Cover If the needle threads (blue and green) are too loose and form small loops on the underside of the fabric. Adjust the blue and green needle thread tensions to a higher setting. If the needle threads (blue and green) are too tight and the fabric is puckering. Adjust the green and blue needle thread tensions to a lower setting.
If the deco cover threads (blue and yellow) are barely visible. Adjust the yellow and blue thread tensions (45) of the deco cover threads to a lower setting. If the needle threads (blue, green and red) are too loose. Adjust the blue, green and red needle thread tensions to a higher setting. If the needle threads (blue, green and red) are too tight and the fabric is puckering. Adjust the blue, green and red needle thread tensions to a lower setting.
Deco Cover 6-thread deco cover, stitch program 28 If all the thread tensions are set correctly, the needle threads (blue, green and red) are almost invisible on the underside of the fabric. The looper thread (purple) lies slack between them. The deco cover threads (blue and yellow) are lying slack around the middle needle thread on the top side of the fabric. There are protruding loops in the deco cover threads (blue and yellow).

Thread Tension Thread Tension This chapter includes information on correct thread tensions for all the stitches you can create with your creative 4874. We also provide you with a number of hints on selecting the correct thread.
Correct thread tension Your 4874 automatically sets the thread tension, stitch length and differential feed for each stitch type. However, the type of fabric, the quality of the thread and the needle size all affect seam formation to some degree, so it may be necessary to adjust the thread tension settings. Also check that your 4874 is threaded correctly and the threads are all the way in the tension discs before adjusting the tensions.
Thread Tension Correcting stitch formation In order to be able to check the thread tension better, you should sew a test seam first, which you can then use to check the looping of the threads. Adjust the thread tension settings as necessary. Hint: If you use all the threads in the respective thread tension color, you will find it easier to adjust the thread tension. This way, you will be able to distinguish more easily between the individual threads in the stitch.
2-needle cover-stitch, narrow and wide Stitch programs 01, 02 If all the thread tensions are set correctly, the needle threads (blue and green) are barely visible on the underside of the fabric. The looper thread (purple) lies slack between them. The right needle thread (green) is too loose. Adjust the green thread tension to a higher setting. The needle threads (green and blue) are set too tightly causing folds in the fabric. Set the green and blue thread tension to a lower value.
Thread Tension 3-needle cover-stitch Stitch program 03 If all the thread tensions are set correctly, the needle threads (blue, green and red) are barely visible on the underside of the fabric. The looper thread (purple) lies slack between them. The needle threads (blue, green and red) are too loose. Adjust the blue, green and red thread tensions to a higher setting. The needle threads (blue, green and red) are too tight and the fabric is puckering.
5-thread safety seam Stitch program 20 Since the 5-thread safety seam consists of a combination of a double chain-stitch and a 3-thread overlock stitch, see below and on page 7-8 for suggestions on how to adjust these stitches. 4-thread safety seam Stitch program 19 Since the 4-thread safety seam consists of a combination of a double chain-stitch and a 2-thread flatlock stitch, see below and on page 7-10 for suggestions on how to adjust these stitches.
Thread Tension 4-thread overlock seam Stitch program 18 If all the thread tensions are set correctly, the looping of the two looper threads (red and yellow) meet right at the edge of the fabric. The upper looper thread (red) appears on the underside of the fabric. Adjust the red thread (upper looper) tension to a higher setting and/or lower the yellow thread (lower looper) tension. Thread tension setting too low. The lower looper (yellow) appears on the upper side of the fabric.
3-thread overlock, narrow and wide Stitch programs 10 and 11 If all the thread tensions are set correctly, the two looper threads (red and yellow) meet right at the edge of the fabric. The needle thread is too loose. Adjust the corresponding needle thread tension to a higher setting. The upper looper thread (red) appears on the underside of the fabric. Adjust the red thread (upper looper) tension to a higher setting and/or lower the yellow thread (lower looper) tension.
Thread Tension 3-thread flatlock, narrow and wide Stitch programs 13 and 14 If all thread tensions are set correctly, thread looping is right at the edge of the fabric. The upper looper (red) and the needle (blue) meet at the edge of the material. The lower looper (yellow) also is at the edge as a straight piece of thread along the edge. The needle thread does not go all the way to the fabric edge (too tight).
2-thread flatlock, narrow and wide Stitch programs 05 and 06 If all the thread tensions are set correctly, the looper and needle threads will meet on the edge of the fabric. Note: To sew the 2-thread flatlock attach the converter as described on page 2-29. The needle thread is too loose or the lower looper thread (yellow) is too tight. Adjust the corresponding needle thread tension to a higher setting and/or change the yellow thread tension to a lower setting.
Thread Tension 3-thread flat hem Stitch program 16 If all thread tensions are set correctly, the upper and lower looper threads meet right at the edge of the fabric. The needle thread (green) is too loose. Adjust the green needle thread tension to a higher setting. The upper looper thread (red) appears on the underside of the fabric. Adjust the red thread (upper looper (red)) tension to a higher setting and/or lower the yellow thread (lower looper (yellow)) tension.
3-thread fold, rolled hem Program 17 If all the thread tensions are set correctly, the upper looper thread (red) loops completely around the edge of the fabric. The needle thread (green) is too loose. Adjust the green thread tension to a higher setting. The upper looper thread (red) only partially loops round the edge of the fabric. Adjust the red thread tension to a lower setting and/or change the yellow thread tension to a higher setting.
Thread Tension 2-thread flat hem Stitch program 08 If all thread tensions are set correctly, the needle thread (green) and lower looper threads meet at the edge of the fabric. Note: To sew the 2-thread flat hem attach the converter as described on page 2-29. The needle thread (green) is too loose. Adjust the green thread tension to a higher setting and/or the yellow thread tension to a lower setting.

If the needle threads (blue, green and red) are too tight and the fabric is puckering, adjust the blue, green and red needle thread tensions to a lower setting. Note: The stitch formation adjustments for programs 26, 27 and 29 are based on those for program 25.
6-thread deco cover Stitch program 28 If all the thread tensions are set correctly, the needle threads (blue, green and red) are barely visible on the underside of the fabric. The looper thread (purple) lies slack between them. The deco cover threads (blue and yellow) are lying slack around the middle needle thread on the top side of the fabric. If there are protruding loops in the deco cover threads (blue and yellow), adjust the yellow and blue thread tensions of the deco cover to a higher setting.
Thread Tension When buying sewing threads, you should bear in mind that your creative 4874 uses considerably more than a conventional sewing machine, so you will need to buy correspondingly larger units of thread. Overlock thread is available in cones (2,000-5,000 m) or mini-kingspools (1,000 m) in a wide range of colors. Of course you can also use standard all-purpose threads. To prevent overlock seams from expanding excessively, we recommend an overlock thread made from 100% polyester, gauge No. 120.
