My Brother LS 2160 is threaded but not stitching

Hi there Kathryn... when you load/thread the top cotton through the machine.... and then through the eye of the needle.... do you also load the bobbin case... or is it already in there and loaded as per instructions... ? What I normally do... is load up the bottom and top threads first.. making sure to put the top thread through the needle and make the thread end go through and behind the 'foot'... when placing on fabric to try... I make sure to load the fabric... with the top thread's tail going out through the presser foot and behind your foot.. sometimes.. if its the thread (some machines don't like certain threads)... I will manually (wind the right hand wheel) so that the machine does a few stitches.. before I use my foot pedal!.. I have both a serger/overlocker... and a Brother 8500 (sewing/embroidery machine).. I have been sewing for over years now...
You will need to change your needle... when you've used it for more than 6-7 hours continuously.. OR you notice that the stitches are not as they should be... in your fabric...

Huskylock 936 will not form a 4-thread overlock stitch

It may be difficult to solve a computer controlled machine with as many options as the 936 serger. Stepper motors control many of the functions. You can check out this video I made 4 years ago to get an idea of where to look.

I'm not sure how to thread my machine, I lost my manual elna lock pro 5Dc

I would suggest that you buy a new manual for this as your overlocker has 5 threads that need to be threaded up correctly to form a stitch and there are several different stitches that can be made with this model such as a rolled hem, chain stitch, three thread overlock, four thread overlock and safety stitch with three thread overlock, lots to learn.

You can buy a manual here for $USD14.99:
or this website has a copy for $USD10.

Always well worth buying the manual and saving a lot of frustration trying to guess how things work and it adds value if you are going to sell the item.

You can get some general overlocker threading tips from which may help you too.

I am trying to do a rolled hem using a singer ultralock 14sh654. Do I disengage the knife? The stitches are uneven and some are quite loose no matter how much I adjust the tension. I am positive I...

no, you need the blade in place and cutting to give an even cut fabric edge. Set up for a three thread using the right hand needle, take out the left hand needle. move blade over to the right so it is cutting wide. Most overlockers there is also a thread finger you need to change on the foot, or a little lever you flick to move this finger forward into the stitching area. Check this on your manual as each make is a bit different.
If you can source it, put wooly nylon thread into the upper looper (knot it onto existing thread and just chain it through, the knot should go through the looper eye fine). Now turn the tension on top looper down so it is looser and tighten up tension on bottom looper, so needle 5, top looper 2 and bottom looper about 7.

Now test serge, the fabric cut edge should be wider than the overlocking seam so the fabric rolls under inside the stitching. Adjust the two looper threads so that this is happening, you want the bottom looper thread to nest right up against the needle stitch and the top looper thread to wrap all the way around too.

Once you've got this happening, turn the stitch length down to 0.5, to close the stitching right up. On some fabrics you'll need to adjust the differential feed too if the fabric is "waving" a bit.

Uneven stitches or sometimes loose when serging could indicate that one of the tension devices is faulting, so if this machine is not new and its doing this, it could need a service. Can you get a regular smooth three or 4 thread seam out if it???

It is always good to just recheck the threading path, make sure the thread aerial is up and that a thread hasn't got caught back on the thread stand somewhere if you're getting something wonky happening, threads stream off overlocker cones through the machine so anything wrong in the thread path will throw off the stitching.

It will not do an overlock it will cut the fabric nothing else I followed the directions on how to thread it but the only thing it will do is cut the fabric what am i doing wrong

for all Sewing machines to stitch the cloth, Top needles and bottom hemming needles timing should be configured. Please let us know the whether it is double needle / single needle overlock machine. and model number of the Machine.So that i can guide much better.

Hi, I am unable to do a overlock stitch , elna l1

Check with sewusa for a threading guide and manual.

Look inside the font door of the machine to see if there is a threading guide.

Sewing machine stopped making the stich

Unthread the needles, rethread the loopers properly, then rethread the needles. Make sure that all four threads are pulled securely into the tensions and retry.

The loopers must always be threaded before the needles or it will not chain.

Thread wont overlock

When the thread breaks too often, try these, that goes for all sewing machines
1. Replace the needles,
2. Loosen slightly the tension of the needle threads.
3. The top threads are to thin,
4.The sewing (rotary) hook or looper, has burs,
5. Wrong threading

Bernina 1300 dc overlocker skipping stitches

Make sure the chain stitch thread is threaded exactly as it should be, make doubly sure the thread comes off the bobbin vertically and runs through all eyes smoothly. Any faults in the threading causes extra tension at the needle despite what the tension is set on.
If this is not the cause then the needle depth and the looper timing needs checking.
