How to replace the upper and lower loopers in Juki MO644D serger

Did they break or are they scared up?
It's not easy to get them right. But try this.

Make sure when you buy your new loopers that you purchase the proper ones for your machine. Loopers are very picky and will not work in the wrong machines.

Do NOT take the old loopers out.
Remove your throat plate and swing your presser foot out of the way. Clean your machine (I like to use a small paint brush and my vacuum cleaner because the fuzz is usually oily.)
Take several pictures of the upper looper coming in from the right. A picture straight in and a couple from the top. Then use a magic marker to mark how far the looper is in the looper holder. Use a small wrench to loosen the screw on top of the holder and pull your old looper out. Transfer the magic marking onto the new looper and install it into the holder and tighten the screw=snug but not over tight or you will twist the head off the screw.
Now, take several pictures of the lower looper coming in from the left and use your magic marker to mark ON THE MACHINE, how far the looper sits down onto the holder. Take the screws out of the old looper, put the new looper in its place, start your screws, line your looper bottom up with your magic marks and tighten the screws.
Do not run your machine yet. Look on the right side of your machine where the handwheel is to see which direction the arrow points, as to whether your machine rotates forwards or backwards and HAND WIND ONLY in that direction until you are sure your loopers are in the correct position and not hitting each other. They should come very close but should not hit. Loopers are not cheap and if you run it before you try this and they are improperly installed, you will either break one or both of the loopers or may actually break your machine.

Now rethread your loopers and reinstall the throat plate and put your presser foot back in place.See if it sews.
If not, take it to a repairman.
Good Luck

I am after a manual for my Singer 1832U machine. I am having problems with looper threads snapping

Singer 1832U Manuals

Usually, breaking threads are a result of misthreading. Remove all the threads from the machine. AVOID old or bargain bin threads! ALWAYS RAISE the presser foot and rethread from the beginning--make sure each thread is threaded in the proper order.

Electric white rotary sewing machine

Confused... How does a sewing machine have a "mn looper?" Sewing machines have a bobbin. A serger has a looper. Perhaps knowing the model would be helpful.

How do I thread my overlocker

It certainly depends on the brand, can you find a manual on line? Typically one way to start is to thread the upper looper, lower looper, left needle, right needle. They can be pretty finicky about which thread lays over the other. It pays to go carefully to avoid being frustrated.

Thread broke on bottom looper the first time out of box i had to try and thread and the tension was still tight The bottom threads were not stiching

I'm going to assume here you're talking about a serger. Unthread the lower looper and the eyes of the needle. Set the lower looper tension to 0. Rethread the lower looper, then the needle eyes. Then reset the lower looper tension (try about half a number lower) and see if it chains. If it won't chain, try replacing the needles.

Can't thread a consew 694ex

Typically a serger is threaded... upper looper(s) Lower looper(s) Needles from right to left. Anything else will cause you problems. If you break a thread... remove all other threads and begin again at the upper loopers.

What are the settings for overlocking stretch fabrics

For knits with lycra in, you are best to thread up four threads and seam with the 4 thread marrowing stitch like this, preferabbly with ball point needles in your overlocker, size 80. Use cones of polyester thread, 3,000 metres or 5,000 metres rather than normal thread. (Although if you have trouble matching thread colours you can use a small reel on the left needle as this is the thread that will show on the right side of the garment.)


Start with your machine tensions on 5, both needles in and threaded, stitch length of 2.5 and no differential (set it on zero) and test stitch. Using stretch or ballpoint needles is a good idea too to avoid any deflection and skipped stitches. Then practice serging on some fabric scraps, double layer and look at the seam, if it is tunnelling (pulling up the fabric), then move the cutting blade to the left. Test again and if still tunnelling, then loosen off the tension on the top and bottom loopers by a half number and test again.

If the opposite is happening and the threads are looping off the edge of the fabric, then move the cutting blade to the right to trim less fabric, test again. If still too loose, then tighten up the top and bottom looper tensions by a small amount and test again.

You want the seam to lie flat, the two looper threads to meet right on the cut edge and the needle thread to be just visible from the right side when you press open the seam.

There is always a small amount of adjustments needed on an overlocker when setting up for a new project as every fabric will behave differently. Don't tighten up the tension on the needles much past 5 though, or you may get thread breakage.

If you find that the seam is flutting then you can use the differential feed to adjust for this too.

There is some good overlocking info on Debbie Cosgroves website,, with images which may help too.

I have rethreaded machine a number of times to try and solve problem however I cannot make sense of instruction 11 the correct and incorrect position showing hook on page 14

If you thread needle before loopers, there is a very real danger of trapping the needle thread under lower looper will then be unable to stitch
ALWAYS thread loopers BEFORE needles to avoid trapping.
To see what happens, thread needles first... then wind one revolution by hand....then thread loopers... see where lower looper thread has now surrounded the needle thread so it cannot be pulled off looper !!
For future questions just ask for "BargainBox" via this link

Glad to help.

Need settings for Simplicity easyLock SL370 rolled hem. Machine belongs to a friend who recently moved and the instruction manual has gone missing. Thank you!

narrow 3thread seam, so remove left needle. loosen top looper tension to 3 or 2, tighten bottom looper tension to 7 or 8. thread top looper with woolly overlock thread and reduce stitch length. there is also a thread finger u need to flick back on throat or needle plate usually to make rolled hem. also move blade to right to trim less fabric as you want the fabtic to roll under inside the seam.

Viking Huskylock 910 Upper Looper problem...

You will find that it was most likely the top looper has moved to the left too far, undo the looper clamp and press the looper to the right by about 3mm. Then turn the machine over to see if it still hits anything, when the top looper comes up past the bottom looper there should be about 0.5mm clearance between the two. Try this first please.
Also the arm shaft may have moved. Trace the shaft back to where there is a clamp type crank with usually a hexagon head clamp screw. Loosen this and set the top looper so as the eye of it is just past the needle when it is all the way up and to the left.
You are correct in not using the machine under power, turn by hand when you think it is correct and make sure there is nothing hitting.
