Always unplug before relamping, and replace the bulb with the same type rated max.12 volts/5 watts. The appliance should not be used as a toy, and close attention is necessary when the appliance is used by or near children. Use the appliance only for its intended use as described in the manual and use only attachments recommended by the manufacturer as contained in the manual. Never operate the appliance if it has a damaged cord or plug, if it is not working properly, if it has been dropped or damaged or dropped into water. Return the appliance to the nearest authorized dealer or service center for examination, repair, electrical or mechanical adjustment. Never operate the appliance with any air openings blocked. Keep ventilation openings of the sewing machine and foot controller free from accumulation of lint, dust and loose cloth. Keep fingers away from all moving parts. Special care is required around the sewing needle and knife. Always use the proper needle plate, as the wrong plate can cause the needle to break. Do not use bent needles. Do not pull or push fabric while stitching, as it may deflect the needle causing it to break. Switch the sewing machine off («O») when making any adjustments in the needle area, such as threading needle, changing needle, threading looper, or changing presser foot and the like. Always unplug the machine from the electrical outlet when removing covers, lubricating or when making any other user servicing adjustments mentioned in the instruction manual. Never drop or insert any object into any opening. Do not use outdoors. Do not operate where aerosol (spray) products are being used or where oxygen is being administered. To disconnect, turn all controls to the off («0») position, then remove plug from outlet. Do not unplug by pulling on cord, instead, grasp the plug not the cord. The machine should be disconnected from the electricity supply when not in use. This appliance is provided with double insulation (except USA/CANADA). Use only identical replacement parts and see instructions for servicing of double insulated products.
What are the steps for servicing double-insulated products?
In a double-insulated product, two systems of insulation are provided instead of grounding. No grounding means is provided on a double-insulated product nor should a means for grounding be added to the product. Servicing a double-insulated product requires extreme care and knowledge of the system and should only be done by qualified service personnel. Replacement parts for a double-insulated product must be identical to those parts in the product. A double insulated product is marked with the words «DOUBLE INSULATION» or «DOUBLE INSULATED». The symbol may also be marked on the product.

How do I attach the foot control?
Plug the foot control into the machine socket on the right side of the machine, then plug the power cord into the machine socket and into the mains socket.
How do I adjust the sewing speed?
Decrease or increase the pressure on the electronic foot control for fully variable speed control. The maximum sewing speed for overlock stitch mode A to E is 1500 s.p.m. The maximum sewing speed for cover/chain stitch mode F and G is 800 s.p.m. The maximum sewing speed for top&bottom cover stitch mode H is 500 s.p.m. The maximum sewing speeds are automatically set by the stitch selection dial.
How do I use the thread stand?
Push the support rod firmly into the socket on the back of the machine. Raise the support rod fully, turning slightly until the positioning catches engage. Position the thread guide on the thread stand so that it is parallel to the machine.
How do I use the 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.
What kind of thread, cones, and spools can be used on the machine?
Cones or domestic spools in all sizes can be used on the 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.
How do I place the spool holder for the top & bottom cover stitch thread?
Lift the foam pad (A), slide the guide tabs © of the spool holder (B) into the guide of the upperside of the spool holder from left to right into position (E) and press until tab (D) clicks into the underside of rib (F).
Where is the power switch located and what are its settings?
The power switch is on the handwheel side of the machine in front of the machine socket. O = OFF and I = ON.
Where is the light switch located and what are its settings?
The light switch is positioned on the rear left side of the machine to the left of the presser foot lifter. 1 = ON and 2 = OFF.
What are the electronic operating and safety features of the machine?
The machine is equipped with electronic operating and safety features. 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. 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. To lower the needle(s), press the Needle stop button. 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. 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. 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. If overheating should occur, the motor will cut-out after 2 seconds, after cooling down, sewing can be continued. If you turn the stitch selection dial while sewing, the control lamp will blink and the machine will stop.
In which direction does the handwheel turn?
The handwheel turns counter-clockwise as on a household sewing machine.
How do I open and close the 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.
How do I remove and attach the cloth plate?
To remove pull to the left. To attach press firmly to the right until it engages.
How do I use the 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. 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. Press the lifter down to lower the presser foot. When the presser foot is raised, all the tensions are released making it easier to thread the machine. If sewing in top & bottom cover stitch mode, when lifting the presser foot to its highest position, do not use any force.
How do I use the swing-out presser 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, then lower the presser foot. The machine will not run when the foot is swung-out. To prevent damaging the needle points, the cover stitch foot (accessory) should not be swung out.
How do I change the presser foot?
Raise the needles (Needle stop), then raise the presser foot. Press the catch to release the presser foot from the clamp and remove it to the left. To attach the foot, place it under the shaft. The groove in the shaft should line up exactly with the presser foot pin. Lower the shank and the presser foot engages automatically. The cover stitch presser foot 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 center section and two spring-loaded side sections. The indents on the center section indicate the needle positions and act as guides. The spring-loaded side sections guide the fabric and prevent sideways movement. To prevent damaging the needle points, the cover stitch foot (accessory) should not be swung out.
How do I adjust the 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.
How do I adjust 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. 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. If the edges of fine fabrics curl when being sewn, reduce the cutting width by turning the dial to a lower number. If the loops formed on the fabric edge are too loose, increase the cutting width by turning the dial to a higher number.
How does the differential feed work and how do I adjust it?
The overlocker is equipped with a front and a rear feed dog. The two feed dogs move independently, and the distance each feed dog travels can be adjusted independently. The distance travelled by the front feed dog is greater than that of the rear feed dog for a gathering effect. 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). The distance travelled by the rear feed dog is greater than that of the front feed dog for a stretching effect. 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). Simply turn the dial in the direction desired for fully variable adjustments while sewing. Test sew.
What are some recommended differential feed settings and their effects?
Setting 2: Gathering effect, flat seams Setting 1.5: Gathering effect, pucker free seams Setting N (1): Normal feed Setting 0.7: Stretching effect
How do I adjust the presser foot pressure?
Push the lever in the direction desired. High pressure (H): For thick or stiff fabrics such as denim, tweed, linen and for sewing on elastic. Normal pressure (N): Basic setting for most normal overlock work. Low pressure (L): For light-weight or sheer fabrics such as chiffon, georgette, batiste, linings. Seams in knitted fabrics will wave if the presser foot pressure is too high. Always set to «N» when sewing knits.
How do I raise and lower the upper knife?
Raise the needle(s) to their highest position (needle stop), and open the looper cover, if sewing in overlock mode. To raise the knife press the upper knife holder to the right and turn the knob clockwise until the knife locks. To lower, press the holder to the right and turn the dial counter-clockwise until it engages. The knife engages in the cutting position.
How do I insert needles?
Needles can be inserted quickly and easily with the practical needle inserter. To remove: Raise the needles (Needle stop) and 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 and insert the needle in the appropriate hole as far as possible into the needle clamp. Tighten the needle setscrew firmly. 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.
What are the needle positions for different stitch types?
Needles are inserted into positions L, C or R depending on the stitch selected. The third needle position ® is for cover and chain stitch applications only. Needle L and C or Needle L is for 5–7 mm overlock. Needle C is for 3–5 mm overlock, and 2–3 mm roll hem. Needles L, C R or needle L and R is for 5 mm cover stitch. Needles L and C or Needles C and R is for 2.5 mm cover stitch left or right of centre. Needles L, C, and R are for 5 mm top & bottom cover stitch. Needles L and C are for 2.5 mm top & bottom cover stitch. Needle R is for chain stitch. Remove all needle(s) not in use, and their corresponding thread(s).
How do I use the 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) and open the looper cover. Attach the converter (stored in looper cover) to the upper looper arm. Insert the wire hook into the upper looper eye from back to front. 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. Before starting to sew, check that the upper looper is correctly positioned by first turning the handwheel a few times to form a chain.
How do I use the stitch selection lever for roll hem?
The selection lever for roll hem is integrated in the stitch plate. When the selection lever is pulled forward, the wide overlock stitch finger is retracted to expose the roll hem pin. The fabric edge is rolled round the pin while sewing to produce a fine and decorative edge finish. For roll hem, pull the selection lever forward towards you. For overlock, push the selection lever back away from you.
What needles can be used with this machine?
The overlocker is equipped with needle system 130/705 H (household needles). However for certain types of sewing, system JLx2 needles can also be used on when sewing cover and chain stitch. It is important to purchase system 130/705H needles for overlocking and JLx2 needles for cover and chain stitch when replacement needles are required. Needles must be in perfect condition. Problems can occur if needles are bent, damaged or blunt, or have hooked points. The needle size used depends on the thread. Use needles no. 70–90.
What are some recommendations for using thread and decorative threads?
Purchase threads on cones or spools which are produced exclusively for over-locking. When using normal spools, use the spool caps. 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.
What are the recommended threads for different applications?
| Thread | Needles | Where | Application |
|---|---|---|---|
| All purpose overlock thread 120/2 (polyester) | 70-90 | Needles-, loopers- and wiper threads | For all overlock- and cover stitch work |

What are the 16 different basic stitches that can be sewn on the 2500DCET?
Overlock stitches are basically formed with two looper threads. Examples include 4 thread overlock with integrated safety seam, 3 thread overlock/flatlock/roll hem/narrow seam. A further selection of stitches can be sewn with one looper using the upper looper converter. Examples: 3 thread super stretch and 2 thread overlock/flatlock/roll hem. The machine can be converted to cover and chain stitch. The cover stitch is 2.5/5 mm wide and is sewn with two or three needles and the lower looper. Chain stitch is sewn with one needle and the lower looper. The top & bottom cover stitch is 2.5/5 mm wide and is sewn with two or three needles, a wiper thread along with a lower looper.
What are the basic settings for the different stitches?
The basic tension settings for sixteen different stitches are distributed over eight positions. The positions A, C, D and E are adjusted for overlock stitches using standard overlock thread. The stitches on Position B are the same as position A but with pre-set tensions for woolly nylon or a similar decorative thread in the loopers. Position F is pre-set for cover stitch, G for chain stitch using all-purpose overlock thread and H for top & bottom cover stitch.
What do the threading symbols on the stitch display mean?
Yellow line = insert needle L and thread. Green line = insert needle C and thread. Brown line = insert needle R and thread. Blue dot = thread the upper looper through the blue guides. Red dot = thread the lower looper through the red guides. Purple dot = thread the lower looper through the purple guides. Small black dot = do not thread needle, remove needle. Attach the upper looper converter (upper looper is not threaded). Move stitch selection lever to overlock. Move stitch selection lever to roll hem. Raise the upper knife and upper knife arm. Attach the cover stitch extension plate. Lower the wiper and finger guard. Press in wiper activating lever.

Raise the presser foot and remove work towards the left. Cut threads (thread cutter). 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 and 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. If the stitch formation is incorrect, it 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. Fine tuning levers are available for the needle L thread (yellow), needle C thread (green), needle R thread (brown), the lower looper (purple), and the wiper thread (grey).
