Hi there i have an Elna 5300 old i know but still going strong although i am having issues with loose threads underneath i have tried the following: Bobbin casing tension Top thread tension Cleaning out bobbing casing Different bobbins threads and needles I am making scrubs for the nhs so really need my machine at the moment any ideas thx

try using gutermann thread and needle according to your fabric thickness and tension dial must be 3-5 and bobbin thread hold the end of the thread and bounce to see how loose the thread is cos if it releases too easy you need to turn the screw on the casing just a little see how you go

Hi. Try this site to look at a free online manual.

I hope this helps!

elna make elinta machine and a 140 is the same threading as a 130
try entering the sites as most I go to require an account ( free) to procedure to read or down load and that process would be better for you
I went google and typed in--user manual for elinta sewing machine model 130-- and the sites show 130, 140 and more so select a site and go from there
thee is also a www.youtube.com>watch that runs for 1.29 and shows how to thread an old elna sewing machine
you might pick up a clue from that film

The only thing to really tighten on a bobbin case is the tension screw. (Unless, what is really loose is the mechanism--hook, shuttle--that the bobbin case fits into.) It will probably be worthwhile to just bite the bullet and buy a new bobbin case for the machine. They aren't that expensive and it certainly will relieve a lot of potential future frustration.

...

Sometimes it helps to try to remove the needle and the bobbincase. If you can get the bobbincase loose, the thread nest can then be removed.

..

it's possible that the machine is out of time
you can check with youtube or fixsewingmachines.com for video's on the problem

try changing the needle--normally flat side goes to the back of the machine
also make the needle & thread will work for the fabric being sewed
make sure the bobbin is turned the right way & inserted correctly in the bobbin case
make sure that the thread has not come off the thread take up lever
clean under the needle plate & in the bobbin area for loose thread & lint

It sounds like the timing may have to be reset or adjusted - it happens, so do not be alarmed.

Open the needle plate, remove the bobbin and bobbin case and clean away any lint or thread snips that may be there.

Re-thread the machine with the presser foot up - always.

If there is still a problem find a dealer who will service the machine for you.

The Elna site should have dealer locations.

Hi! Congratulations on your old Elna! I just love old sewing machines; they are so solid and reliable.

(Unless of course you're getting a big bird's nest with the bobbin thread, right? That's so frustrating!)

With my old machines, I've found that a tiny bit of thread caught in the bobbin assembly can cause these nasty tangles. I use a bright flashlight and a pair of tweezers and just keep looking until I find it. While you're in there, clean out any old lint or gunk (meaning, old oil) you find. Brush all the lint out. I use a q-tip moistened with a bit of WD-40 to clean the gunk (but be careful that the fuzz from the q-tip doesn't come off while you're cleaning). With the WD-40, you have to be very careful not to get any of it on the surface of the machine--it can mess up some of those beautiful old finishes.

So clean the bobbin area, make sure you're threading the bobbin correctly, and lastly, if you hold the tails of the top and bobbin threads snugly in your left hand behind the needle while you take the first few stitches, the birds' nests should be a thing of the past.

Let me know if this works, ok?

Happy Sewing!

You should be able to buy a manual online but it may be a cd or image pdf file. Try www.sewingpartsonline.com or www.sewusa.com. If they don't have the Carina but have the Air Electronic SU, model 68 then this will be almost the same. Main difference is the Carina has the needle up/down button.
