If the left needle is closer to you than the right, you probably need a new needle clamp. Remove the needle plate and set the tip of the lower looper behind each needle and check to see if one needle is closer to the looper than the other one. If it is, have an authorized dealer replace the needle clamp. If they say you have to have a new needle bar also, that may well be true since a newer version of the needle clamp requires an updated needle bar.

SOURCE: Needle hitting bobbin plate

Is the needle inserted correctly with the flat side at the rear and fully up into the holder ?

If yes, take off the needleplate, remove bobbin case and slowly rotate the handwheel towards you watching the relationship between needle, and the "hook" of the moving "race".

Set on wide zig zag........when the needle is fractionally past it's lowest point, and starting to rise, the hook should be level with the left side of the needle when on the right hand stitch of the zig...the eye of the needle will be below the hook, and ready for thread to be picked up for the stitch to form.

Any other result will mean your timing needs adjusting.

Your hook/needle timing is off and it needs to be seen by a technician before you damage the hook. Some dealers can do a 24 hour repair for an additional charge.

SOURCE: Pfaff serger stuck

your needle bar has been pushed up and is out of adjustment. You need to take off the side cover, there should be a screw on the back of your machine holding it on. Remove this screw, and remove the cover.You may have to remove the light assembly to reach the screw on the needle bar. Once you can see the needle bar, rotate the handwheel until you can see the screw on the needle bar. Loosen this screw SLIGHTLY until you can turn the needle bar. Hold and rotate the needle bar back and forth as you push down slightly. This will lower the bar.Lower it about 1/4 inch. Adjust the needles by turning the bar so that they are straight across. Tighten the needle bar screw so that the bar doesn't move. Turn the handwheel to see if the threads will be picked up. If not, adjust until they are. Tighten the needle bar screw tightly,reinstall the side cover ,and tighten the screw. Change your needles.Rethead and sew.

SOURCE: I have a white superlock 228 jaguar serger problems with right needle

Couple of things I could think of: tension disks need cleaning, there is a site that tells how to clean them, maybe 2 as I recall. Other thing is it is a much older serger, (I have one I am slowly working on to bring up to working level), so it could be that a tension spring internally has lost its tension. It might need a trip to the repair man if that is the case. Another thing is are you using correct needles for the machine? Have you changed them recently? Even new needles can be bad, so if you have to change three times to triple check it can be worth it.

SOURCE: White Serger 1934D not stitching

No, Sounds like the loopers are not passing properly to pick up the thread, from off the needles.

Can I use a twin needle on a Pfaff 2056


Since your machine can do decorative stitches, I would think it can take a twin needle. Just BE SURE you have installed the needle plate with the wide hole for the needle and do NOT set a wider stitch than the twin needle can accommodate on it's widest setting without checking by turning the handwheel--the twin needle will overreach and either hit the presser foot or needle plate and sent needle shards flying!!! The manual should have instructions.

My Pfaff 4872 cover.ock serger will not trim the fabric. Also the stitch plate is raised up and won't remain in place.


The upper blade can be replaced by the user. However, because the needle plate is not seated properly, there could be a timing issue with the machine. Best to take it for service...

Serger is not stitching


... not quite sure what you mean by "not stitching", here are a few things to check. If the problem is more specific, please leave me a note with more details.
Let's start right from the beginning (for 4-thread overlock/serge):
1. According to the serger manual, ensure that the proper needles are being used. That they are inserted all the way up into their positions and that the flat side of the needle is facing away from you. The left needle will appear to be shorter that the right, that is OK, all is going perfectly.
2. Use four good quality spool of serger thread (good quality sewing thread is fine also) and place them on the spool or cone holders. There should be "little bucket looking things" that fit onto the cone pins to make the cones sit nice and straight, use them. Rattling thread will cause grief.
3. The first thread to be loaded onto the serger is the Upper Looper ...it is the big needle looking thing that swings left to right and back again above the sewing surface. Follow all the threading guided according to your manual, the threading guides are generally coded in a colour specific for this looper. Once the eye of the Upper Looper is threaded, place the thread under the presser foot and to the left. Presser foot down.
4. Next is the Lower Looper, the big needle looking thing that swings left to right and back again under the sewing surface. It can be a bit tricky in some sergers as the thread need to pass to the left and then back to the right under the sewing surface. Your manual should have a good diagram if you can not follow the threading guides on the serger itself. Again the threading guides are generally colour coded with a different colour but specific for the Lower Looper. Once the looper is threaded, it is important that the thread is placed directly OVER the Upper Looper as it comes out of the eye of the Lower Looper. Place the thread now under the presser foot and to the left. Presser foot down.
5. Thread the right needle front to back and place the thread under the presser foot and to the left. Presser foot down.
6 Thread the left needle front to back and place the thread under the presser foot and to the left. Presser foot down.
7. Hold the four thread ends firmly in the left hand and give each thread individually a good pull down over the serger and behind, this will ensure that the threads are all engaged in the tension dials.
8. Set the tensions to the middle number, although this may vary with the brand and model of your serger. If you have the manual check for the correct settings specific to your unit.
9. Set differential to 'normal', or '0' (if your unit has one)
10. Set stitch length to about 2 1/2 to 3.
11. Make sure that the blade is in cutting position. We can trouble shoot blade position later if needed.
12. Make sure that you have the overlocking plate installed ... not the rolled hem plate (if your serger has two plates). Some sergers use the same plate for both functions.
13. Using two layers of medium weight fabric do a test stitch, what is the result? Is a chain forming? Are there stitches on the fabric? Are they looking the way they should?
Hopefully this has helped you, please let me know.
Cheers.

Why does the left needle thread on my pfaff coverlock 4862 break


The top thread breaks
1. the needle thread is not threaded properly
2. The needle thread tension is to tight
3. The needle is bent or blunt
4. The needle is incorrectly inserted
5. The needle thread & the bobbin thread are not set under the presser foot when starting to sew
6. the threads were not drawn to the rear after sewing
7. The thread is either to heavy or to fine for the needle
8. Try a different spool or cone of thread

Thread keeps breaking


It sounds like you the thread is passing a place with a burr, it could be in the needle (replace needle) or on the stitchplate (maybe a bent needle hit the stitch plate and put a knick in it, a sewing repair man can sand it out). Or you don't have the tension right. Or you may have cheap thread that is not strong enough. I hope some of these suggestions are helpful.

My white 2000 serger is dropping the thread on the first needle when I sew with it- the loopers, both upper and lower are working correctly in conjunction with the "right upper" needle. I have changed...


Could be as simple as poor quality thread (not using MaxiLock thread), the needles not inserted properly (the left is slightly higher than the right), a missing stitch forming pin on the needle plate, the needle bar being too high or a looper timing issue.

As the needles raise, the upper looper should move to the right with the right needle tip slightly above the eye of the looper.

Instructions for threading Baby lock eclipse BLE1LX for 2 thread sergering


I have just learned this :)
Either needle thread may be engaged for 2-thread serging.
1. Open the front cover and cutting blade cover, cut the upper looper thread just above the threading guide ( this is plate that has two holes for the threads) Raise the presser foot and pull out the clipped thread from under the foot. Remove upper thread from the machine (or you can leave the cone thread on, it doesn't matter).
2. Rotate the handwheel to bring the upper looper to its lowest position.
3. Rotate the subsidiary looper up and to the left, then slip the end into the upper looper thread eye from backside.(this sounds complicated, yes? but it is very simple : the looper has a counter part that is spring-locked to move from left to right and right to left. This is the little claw-looking part of the looper that when in the postion to serg with four threads is to the right side of the looper. It looks like a scorpion's tale. If you can't figure which part it is, use your finger to probe the looper and you'll feel it give a little. This part needs to be moved to the left - it will not slide over, but swing up and over and down, like an arch. Then, where the thread comes out of the looper is where you want the little claw-like part to hook into.)
4. Close the covers. Decrease the needel tension - this depends on what the stitch length is. Stitch length: 2-3, stitch width: 3.0 = L needle n/a, R needle 1; upper looper n/a, lower looper 5
stitch length: 2-3, stitch width: 5.0 = L needle 0, R needle n/a, upper looper n/a, lower looper 3.5

Those are for a flatlock stitch - for a 2-thread rolled edge :
Stitch length: 0.5, stitch width: M = L needle n/a, R needle 4.5, upper looper n/a, lower looper 3.5
Stitch lenght: 1.0, stitch width: M = L needle n/a, R needle 4, upper lopper n/a, lower looper 3.0
