12 Waste collector Hang the waste collector onto the opening provided on the looper cover. It catches the cut-off fabric as you sew, keeping your working area neat and tidy. Thread, cones, spools Cones or domestic spools in all sizes can be used on your BERNINA overlocker. Remove the stabilizers for household spools, but secure the spools with the spool holder caps, rounded side downwards. When sewing with large industrial spools, use the stabilizers upside down, i.e. with the wider edge at the top. Place the stabilizers on the spool pins when using thread cones. 2500_DCE_1_englisch_neu 09.10.2007 14:33 Uhr Seite 12

1 2 Power switch The power switch is on the handwheel side of the machine in front of the machine socket. O = OFF I = ON Light switch The light switch is positioned on the rear left side of the machine to the left of the presser foot lifter. 1 = ON 2 = OFF Electronics/Safety/Needle stop Your Bernina overlocker is equipped with electronic operating and safety features. Micro-safety switch: When the looper cover is open, the electricity supply to the motor is automatically interrupted. The machine will not sew but the light remains on for threading etc. Needle stop: The Needle stop for overlock stitches (positions A to E) is generally up, i.e. when you stop sewing, the needle(s) will stop in their highest position, the ideal position for threading or changing needles. To lower the needle(s), press the Needle stop button (3). The Needle stop for cover and chain stitch (positions F/G/H) is generally down, i.e. cover and chain stitch formations end with the needle in the fabric. Safety control lamp: The machine will not sew if it has not been prepared correctly. When the foot control is depressed, the safety control lamp will light up (4). The control lamp also lights up when the presser foot is raised, when the presser foot is swung out or the looper cover is open. Safety cut-out If overheating should occur, the motor will cut-out after 2 seconds, after cooling down, sewing can be continued. Note: If you turn the stitch selection dial while sewing, the control lamp will blink and the machine will stop. 4 3 2500_DCE_1_englisch_neu 09.10.2007 14:33 Uhr Seite 14

15 15 15 Handwheel The handwheel turns counter-clockwise as on a household sewing machine. Looper cover To open the looper cover, press to the right and tilt the cover towards you. To close the cover, push it up and press lightly to the left and it will engage automatically. Cloth plate / free-arm The cloth plate can be removed to expose the free arm. To remove pull to the left. To attach press firmly to the right until it engages. The free arm is ideal for sewing tubular items such as ribbing, trousers and sleeve hems. Two-step presser foot lifter The presser foot lifter is positioned on the rear of the machine above the presser foot. To raise the presser foot, lift the presser foot lifter until it engages (1). It can be raised again to maximum height and held in this position to provide more space between presser foot and stitch plate for bulky items. (2). Press the lifter down to lower the presser foot. Note: When the presser foot is raised, all the tensions are released making it easier to thread the machine. WARNING: If sewing in top & bottom cover stitch mode, when lifting the presser foot to its highest position (2), do not use any force. 1 2 2500_DCE_1_englisch_neu 09.10.2007 14:33 Uhr Seite 15

Swing-out presser foot The swing-out foot (exclusive by BERNINA) provides easy access for threading needles. It also makes it easier to change the needles and insert band or elastic into the guide on the foot. To swing out: · Raise the needles (Needle stop). · Raise the presser foot and swing it out to the left. To position for sewing: · Push the foot from left to right until it engages. · Lower the presser foot. Note: The machine will not run when the foot is swung-out. An additional safety measure to prevent damage to needle(s) or machine. Note: Cover stitch compensating foot: To prevent damaging the needle points, the cover stitch foot (accessory) should not be swung out. Changing the presser foot · Raise the needles (Needle stop) · Raise the presser foot. · Press the catch (1) to release the presser foot from the clamp (2) and remove it to the left. 1 2 3 To attach the foot, place it under the shaft. The groove in the shaft should line up exactly with the presser foot pin (3). Lower the shank and the presser foot engages automatically. The cover stitch presser foot (compensating foot – accessory) is used together with the seam guide lines on the extension plate and for work where precise guiding is necessary. The cover stitch presser foot consists of a solid centre section and two spring-loaded side sections. The indents on the centre section (1) indicate the needle positions and act as guides. The spring-loaded side sections (2) guide the fabric and prevent sideways movement. Perfect for topstitching hems with elastic, folded edges, seams and ribbings as well as bindings or sewing on lace or elastic. Note: Cover stitch compensating foot: To prevent damaging the needle points, the cover stitch foot (accessory) should not be swung out. 2500_DCE_1_englisch_neu 09.10.2007 14:33 Uhr Seite 16

17 17 17 Stitch length Every stitch equals one complete feed-dog movement. The amount of movement is determined by the selected stitch length. The stitch length is infinitely variable from 1–4 mm and can be adjusted while sewing. Simply turn the stitch length dial in the direction desired. Most overlock work is done with a basic stitch length setting of 2.5 mm (marking on the dial). Most cover stitch work is done with a stitch length of between 3 and 4. Cutting width Adjusting the cutting width for overlock stitches: Turn the dial in the direction desired. The upper knife adjusts automatically to the position of the lower knife. The stitch width of overlock stitches is determined by the cutting width and the needle(s) in use. Note cover/chain stitch: Cover and chain stitches are sewn without knives. The upper knife and upper knife arm are fully raised when the machine is in cover/chain stitch mode. Position of knife: 1 2 3 Needle C: 3 mm 4 mm 5 mm Needle L: 5 mm 6 mm 7 mm 2500_DCE_1_englisch_neu 09.10.2007 14:33 Uhr Seite 17

Cutting width Narrower cutting width: If the edges of fine fabrics curl when being sewn, reduce the cutting width by turning the dial to a lower number. Wider cutting width: If the loops formed on the fabric edge are too loose, increase the cutting width by turning the dial to a higher number. Differential feed Your BERNINA overlocker is equipped with a front (1) and a rear (2) feed dog. The two feed dogs move independently, and the distance each feed dog travels can be adjusted independently. 2 1 2 1.5 N (1) 0.7 Gathering effect This is the most common use for differential feed and is to prevent waving or fluting in knits or puckers in fine woven fabrics. The distance travelled by the front feed dog is greater than that of the rear feed dog. The front feed dog pushes the amount of fabric which the rear feed dog can take up unstretched (knit) or unpuckered (fine wovens) behind the needle(s) (e.g. 1.5 and 2). Stretching effect The opposite effect can be produced to prevent fine nylon jerseys or closely woven fabrics from puckering. The distance travelled by the rear feed dog is greater than that of the front feed dog. The front feed dog holds the fabric back so that the rear feed dog can take up the fabric (slightly stretched) behind the needle(s). (e.g. 0.7). Adjusting the differential feed Simply turn the dial in the direction desired for fully variable adjustments while sewing. Test sew. 2500_DCE_1_englisch_neu 09.10.2007 14:33 Uhr Seite 18

Presser foot pressure The presser foot pressure ensures perfect fabric feed. It is factory adjusted to a medium setting. Adjusting the pressure: Push the lever in the direction desired. H High pressure: For thick or stiff fabrics such as denim, tweed, linen and for sewing on elastic. N Normal pressure: Basic setting for most normal overlock work. L Low pressure: For light-weight or sheer fabrics such as chiffon, georgette, batiste, linings. Note: Seams in knitted fabrics will wave if the presser foot pressure is too high. Always set to «N» when sewing knits. Upper knife Raise the needle(s) to their highest position (needle stop). Open the looper cover, if sewing in overlock mode. To raise the knife press the upper knife holder (1) to the right. Turn the knob (2) clockwise until the knife locks (3). To lower, press the holder to the right and turn the dial (2) counter-clockwise until it engages. The knife engages in the cutting position. 1 2 3 2500_DCE_1_englisch_neu 09.10.2007 14:33 Uhr Seite 20

21 21 21 Needle clamp BERNINA 2500DCET needle clamp There are three needle positions (L, C, R) each with its own fixation screw. Inserting needles Needles can be inserted quickly and easily with the practical needle inserter. To remove: · Raise the needles (Needle stop). · Raise the presser foot and swing out or remove. Loosen the fixation screw and remove the needle using the inserter. Place the replacement needle, flat sides towards the back, into the hole of the needle inserter (1) and insert the needle in the appropriate hole as far as possible into the needle clamp (2).Tighten the needle setscrew firmly (3). Tip: Insert the needle C first and then needle L. Needle L is slightly higher than the needle C. Use needle R for cover and chain stitch. Needle positions Needles are inserted into positions L, C or R depending on the stitch selected, which produces different stitch widths. Note: The third needle position (R) is for cover and chain stitch applications only! Needle L and C or Needle L 5–7 mm overlock Needle C 3–5 mm overlock 2–3 mm roll hem Needles L, C R or needle L and R 5 mm cover stitch Needles L and C Needles C and R 2.5 mm cover stitch left or right of centre Needles L, C, and R 5 mm top & bottom cover stitch Needles L and C 2.5 mm top & bottom cover stitch Needle R Chain stitch Note: Remove all needle(s) not in use, and their corresponding thread(s).

Upper looper converter Attach the upper looper converter for overlock stitches sewn with one looper, e.g. 2 thread roll hem or 2 thread flatlock. · Lower the needles (press Needle stop) · Open the looper cover Attach the converter (stored in looper cover) to the upper looper arm (1). Insert the wire hook into the upper looper eye from back to front (2). The upper looper has now been converted, i.e. it no longer carries thread but it diverts the lower looper thread so that loops are formed round the edge of the fabric. Tip: Before starting to sew, check that the upper looper is correctly positioned by first turning the handwheel a few times to form a chain. 1 2 4 6 Stitch selection lever/roll hem on the stitch plate The selection lever for roll hem is integrated in the stitch plate. When the selection lever is pulled forward (3), the wide overlock stitch finger (4) is retracted to expose the roll hem pin (5). The fabric edge is rolled round the pin while sewing to produce a fine and decorative edge finish. 5 3 For roll hem, pull the selection lever forward towards you (3). For overlock, push the selection lever back away from you (6). 2500_DCE_1_englisch_neu 09.10.2007 14:34 Uhr Seite 22

23 23 23 23 Needles and machine Your BERNINA overlocker is equipped with needle system 130/705 H (household need- les). However for certain types of sewing, system JLx2 needles can also be used on Needle and fabric Needles must be in perfect condition. Problems can occur if needles: A B C Needle and thread The needle size used depends on the thread. The needles hould be in accordance with thread used. Thread/decorative threads Sewing and special overlock threads are manufactured in a wide variety of types, weights and combination fibres. It is worth investing in good quality threads for perfect sewing results. Decorative threads specially made for overlockers (avai- lable on cones) are also becoming widely available. We recommend following basic guidelines when using special threads on your overlocker: the BERNINA 2500DCET when sewing cover and chain stitch (Positions F and G). It is important to purchase system 130/705H needles for overlocking and A are bent B are damaged or blunt C have hooked points When sewing, the thread is fed through the long groove in the needle. If the needle is too fine, the thread does not fit into the groove and stitches will be skipped. Use · Purchase threads on cones or spools which are pro- duced exclusively for over- locking. · When using normal spools, use the spool caps (in accessory bag). · Only use decorative threads in the loopers. The thread must move easily and without resistance through the thread guides and looper eyes. · The thicker the thread, the longer the stitch length (3–4). · The thicker the thread, the looser the tensions · Sew slowly when using decorative threads. Pull the thread chain gently to the rear when starting to sew. · Always test sew decorative threads before starting to sew your work. · Use the deco-guide when sewing thick or decorative threads (see page 36. ) Thread, needle, application table cover stitch or JLx2 needles for cover and chain stitch when replacement needles are required. needles no. 70–90 on your BERNINA overlocker.

General threading instructions Thread the machine in the following sequence. Overlock stitches: 1. Upper looper (blue markings) 2. Lower looper (red markings) 3. Needle C (green markings) 4. Needle L (yellow markings) Tip: When threading for the first time, use coloured threads to match the threading codes, i.e. blue, red, green and yellow for 4-thread overlock, so that when you test sew, you can see exactly how the stitch is formed. Cover stitch/top & bottom cover stitch: 1. Lower looper (purple markings) 2. Needle R (brown markings) 3. Needle C (green markings) 4. Needle L (yellow markings) 5. Wiper thread (grey markings) Preparation · Raise the support rod fully · Raise the needles (Needle stop) · Raise the presser foot. The tensions release automatically. · Swing foot out. · Open the looper cover. · Raise the upper knife (if wanted) First thread guide on the machine Thread the first guides on the top of the machine as follows: Holding the thread with both hands slip it into the appro- priate guide from back left to front right in the direction of the arrow and pull gently to check that it is lying correctly. Needle/looper threader Insert the thread into the threader. Push the rigid end of the threader through the needle or looper eye and pull it completely through. Tip: When threading for the first time, use the same coloured threads as the markings, i.e. purple, brown, green and yellow) for 4 thread cover stitch, so that you can see exactly how it is formed. Chain stitch: 1. Lower looper (purple markings) 2. Needle R (brown markings) Your BERNINA overlocker is equipped with practical threading aids: · Stitch display with threading information · Coloured threading diagram inside the looper cover · Colour coded threading paths · Lay-in thread guides · Threading accessories in the looper cover 2500_DCE_1_englisch_neu 09.10.2007 14:34 Uhr Seite 30

1 2 A B C D A B C D After threading select the stitch of your choice (stitch selection dial) and test sew. Seam begin, seam end, thread cutter Raise the tip of the presser foot with your thumb and position the fabric just under the foot. Let go of the foot and start to sew. The fabric will be taken up automatically. At the end of the seam, continue sewing a 8 cm (3") long thread chain (1). Holding the fabric in your left hand, pull the thread chain over the thread cutter (2). Fine tuning Compare your sewing test with the stitch formations on the waste collector or diagram inside the looper cover. Example: 4 thread overlock A Needle L thread (yellow) B Needle C thread (green) C Upper looper thread (blue) D Lower looper thread (red) The upper looper thread lies on the upper side of the fabric and the lower looper thread lies on the underside of the fabric. The loops formed by both threads meet exactly on the edge of the fabric. Needle C thread forms a stretchy safety seam in the centre of the stitch. Needle L thread anchors both looper threads. Stitch formations which are not perfect can be corrected with fine tuning (3). To increase the tension, move the fine tuning lever up. To reduce the tension, move the lever down.

2 1 Deco guide The deco guide (in the accessory bag) is specially designed for sewing wide seams and edges with decorative threads (see section Threads/Decorative thread page 23). Position the guide over the top of the machine over one of the thread slits (1) and tighten screw (2). Take the thread through the deco guide without threading the first machine guide or tension slit. 3/4 thread overlock with medium to heavy weight thread: position the guide over the upper looper tension. 2 thread overlock with heavy thread: position the guide over the lower looper tension. 3 thread overlock with fine rayon embroidery thread, e.g. Rayon No. 40: take threads through the deco guide to the needles. Test sew. 2500_DCE_1_englisch_neu 09.10.2007 14:35 Uhr Seite 36

Fine tuning for 3/4 thread over- lock and 3 thread narrow seam: The loops are formed on the underside: Increase the upper looper tension (blue). Reduce the lower looper tension (red). The loops are formed on the upper side: Increase the lower looper tension (red). Reduce the upper looper tension (blue). Needle C thread forms loops on the underside: Increase the needle tension (green). Needle L thread forms loops on the underside: Increase the needle tension (yellow). Reduce the lower looper tension (red). Fine tuning for 3 thread super stretch, 2 thread wrapped overlock and 2 thread roll hem The needle thread forms loops on the underside. Reduce the lower looper tension (red). Tip: The elasticity of the 3 thread super stretch stitch can be increased by redu- cing the needle tensions or shortening the stitch length, depending on the fabric and application. Fine tuning for 3 thread flatlock The loops are formed on the upperside: Reduce the upper looper tension (blue). Increase the needle (yellow or green) or increase the lower looper tension (red). The loops are formed on the underside. Increase the lower looper (red) or upper looper tension (blue). Reduce the needle tension (yellow or green). The deco guide could be used. Fine tuning for 2 thread flatlock The loops are formed on the underside: Increase the lower looper tension (red). Reduce the needle tension (yellow or green). The deco guide could be used. The loops are formed on the upperside: Reduce the lower looper tension (red). Increase the needle tension (yellow or green). Fine tuning for 3 thread roll hem The loops do not meet at the line of the needle thread on the underside: Increase the lower looper (red) or needle thread (green) tension. Reduce the upper looper thread tension (blue). Tip: Use woolly nylon in the upper looper only. 2500_DCE_1_englisch_neu 09.10.2007 14:35 Uhr Seite 37

Cover Stitch The 5 mm wide cover stitch is formed with two or three needle threads and one looper thread. The needle threads appear as two or three parallel lines on the right side of the fabric. The 2.5 mm cover stitch is sewn with two needle threads and one looper thread. The looper thread covers and neatens the seam on the wrong side. The elasticity of cover stitch makes it ideal for all stretch fabrics. The cover stitch is sewn in the fabric and not on the fabric edge, i.e. the fabric is not cut. The upper knife and upper knife arm are raised. The cover stitch gives a truly professional finish to all your home sewing. It is perfect for hems, top stitching, flat joining seams and edging with elastic and bindings. Stitch selection dial/position F To select cover stitch turn the stitch selection dial to position F. The sewing speed on position F is automatically reduced from 1500 s.p.m. to max. 800 s.p.m. The needle stop is automatically set to down. The cover stitch formation ends with the needle inserted in the fabric. Note: When sewing is completed or interrupted, the needles stay in the fabric. This is ideal for positioning your work while sewing. To remove your work, raise the needles by turning the handwheel backwards, i.e. away from you in a clockwise direction. Chain stitch Stitch selection dial/position G To select chain stitch turn the stitch selection dial to position G. The sewing speed on position G is automatically reduced from 1500 s.p.m. to max. 800 s.p.m. The needle stop is automatically set to down. The chain stitch formation ends with the needle inserted in the fabric. Note: When sewing is completed or interrupted, the needles stay in the fabric. This is ideal for positioning your work while sewing. To remove your work, raise the needles by turning the handwheel backwards, i.e. away from you in a clockwise direction.

To select cover stitch turn the stitch selection dial to position H. The sewing speed on position is automatically reduced from 1500 s.p.m. to max. 500 s.p.m. The needle stop is automatically set to down. The cover stitch formation ends with the needle inserted in the fabric. Note: When sewing is completed or interrupted, the needles stay in the fabric. This is ideal for positioning your work while sewing. To remove your work, raise the needles by turning the handwheel backwards, i.e. away from you in a clockwise direction. WARNING: If sewing in top & bottom cover stitch mode, when lifting the presser foot to its highest position (2), do not use any force. Cover/chain stitch functions and general operating instructions Top & bottom cover stitch The 5 mm wide top & bottom cover stitch is formed with two or three needle threads, a wiper thread and one looper thread. The needle threads appear as two or three parallel lines on the right side of the fabric. The 2.5 mm top & bottom cover stitch is sewn with two needle threads, one wiper thread and one looper thread. The wiper thread covers the seam on the right side, while the looper thread covers and neatens the seam on the wrong side. The elasticity of cover stitch makes it ideal for all stretch fabrics. The cover stitch is sewn in the fabric and not on the fabric edge, i.e. the fabric is not cut. The upper knife and upper knife arm are raised. The cover stitch gives a truly professional finish to all your home sewing. It is perfect for hems, top stitching, flat joining seams and edging with elastic and bindings. Looper conversion arm · Lower the needle clamp, press Needle stop. The loopers are automatically lowered. · Open the looper cover. · The looper conversion arm can now be moved from overlock to cover/chain stitch or from cover/chain stitch to overlock (1). When the conversion arm is switched from overlock to cover/chain stitch, the upper looper is released and the movement of the lower looper becomes elliptic. When the conversion arm is switched from cover/chain stitch to overlock, the upper looper is reinstated and the lower looper moves left and right. 1 2500_DCE_1_englisch_neu 09.10.2007 14:35 Uhr Seite 39

Raise the presser foot and remove work towards the left. Cut threads (thread cutter). Fine tuning top & bottom cover stitch Compare your result with the stitch formation on the threading diagram in the looper cover. The needle threads form two or three straight lines on the upperside of the fabric. They appear as dots on the underside of the fabric. The wiper thread forms horizontal loops between the two or three needle threads on the upper side of the fabric. The looper thread forms horizontal and vertical loops between the two or three rows of needle threads on the underside of the fabric to give a stretchy, durable seam. Incorrect stitch formation can be corrected by fine tuning. To increase the tension push the fine tuning lever up. To reduce the tension push the fine tuning lever down.

more than the basics of sewing in an instruction manual. However, the creative potential of your BERNINA overlocker and sewing machines is enor- mous. To help you use your machines to the full, BERNINA regularly publishes sewing literature which covers a multitude of sub- jects from simple sewing techniques to advanced fashion and craft projects. Ask your BERNINA dealer for details. BERNINA Sewing Service Leaflets Each issue of our Sewing Service Leaflets deals with a particular sewing technique in easy to follow steps. Success is guaranteed!

Contributions from around the world with fascinating ideas for working with textiles are included in every issue. Special sewing tech- niques are described in easy to follow step-by-step photo sequences. We also of course report on new in-house deve- lopments as well as interes- ting news from the sewing market. The Creative Sewing magazine is a real source of inspiration – order your next copy from your BERNINA dealer! BERNINA Collection The BERNINA Collection is a range of booklets which deal with the latest sewing trends. Each Collection covers one particular theme with a variety of creative examples. Pattern sheets where appro- priate, a wealth of back- ground information, fabric and pattern suggestions, ideas for individual design solutions and tips and tricks of the trade ensure profes- sional results. Comprehensive and fully illustrated instruc- tions for BERNINA sewing machines, overlockers and special presser feet guaran- tee sewing success. They are published two to three times a year.
