There are two types of discs - single and double.
For the thinner single discs do as follows:
1.Turn stitch width knob to "0"
2. Turn stitch length knob to "0"
3. Insert the single disc
4. Turn the top selector to "A"
5. Make sure the needle selector is in the centered position.
6. You may now choose any stitch length or width you wish. I usually try "3" for the width and 1/2 for the length to start.
For the thicker double discs do as follows:
1.Turn stitch width knob to "0"
2. Turn stitch length knob to "0"
3. Insert the double disc
4. Turn the top selector to "A"
5. Make sure the needle selector is in the centered position.
6. You may now choose any stitch width.
7. The stitch length must be put on "A" - this is the difference between the single and double discs! I hope this helps!
You'll need to use two separate spools of thread. Machines that take a twin needle will usually have separated thread guides and two separate tension disks. Just make sure the threads are not twisted when threading. Might be better to thread one all the way through and then thread the second.
How To Use Twin Needles
Be sure to check the width of your stitch when using a twin needle. Because the needles will be wider than a single needle, it is very easy to hit the needle plate if setting it too wide.

it sounds like the needle hook timing is out. You need to get the needle
in the lowest position and measure the gap from the needle to the hook
point on the bobbin shuttle. It should be 1/4". You will need to remove
the foot and foot plate to be able to see. I use a 1/4" drill bit as a
gauge. If you need to adjust it, you will need to remove the free arm
cover to the right of the foot and loosen the 2 allen head screws that
hold the drive gear. Adjust the gap, tighten the screws and retry.
Usually if the needle catches the thread to early, it will make a bad
stitch and the upper thread will break. If it catches to late, it will
make thread loops and the machine will skip stitches. Good luck, these
are a good machine and worth fixing. Phil
The fabric is puckering because of fabric slippage. The pressure of the foot is keeping the fabric from moving when the feed dogs move the lower layer of fabric. I think this machine may have a pressure adjustment regulator on it. If it does.it is on the top left side,towards the back of the machine. It will be round and chrome color. Loosen the pressure and, if necessary, pull the fabric gently towards the rear while you are sewing. A walking foot attachment will help but since it is so wide you may not be able to use it.A roller foot is an acceptable substitute but that may be too wide also.If everything else fails you will need to pin the layers together to keep them from slipping. Hope this helps. Sewman7 P.S. Please don't rate this post unless it solves your problem. Thanks
I am not sure which machine you are using, but I have an Elna 9000. The only code I have ever seen come up on the screen is "btr" which signifies that the batteires for the electronic memory are running low. My machine will continue to sew, but this code comes up every time I turn the machine on - then the machine sets itself up normally and will sew fine. Plus, changing the batteries cancels all the memorized information on my machine.
I am not sure if this is the same code you are getting. My Elna 9000 manual does not list any other codes for the machine.
Have you taken your machine to a service dealer to have them check it out?
Best of luck. I know it is frustrating when you are in the middle of a project and have to stop to have your machine serviced.
