I have a Elna air electronic 68, I am not able to use different function. Like thr preprogrammed.


Your AE 68 will have three dials across the front, from L-R, stitch selector, stitch width and stitch length. To sew any stitch with a sidewise needle movement, you will need to turn the stitch selector to that stitch on the selector, then turn the stitch width to between 3 and 4 and the stitch length to a similar setting, adjusting to get the stitch formation you need. To sew with the discs, set all the dials to zero, then insert a cam into the Elnagraph on top of the machine. Then turn the selector to the disc icon, and the stitch length around to the "S" and stitch width to 4.

Don't use reverse if using the elnagraph stitches.

My machine worked fine and I go to use it and I put the bobbin in and I can't get the needle to go down I cleaned out the bobbin case and still it won't work. What do I try now?


Model and make of machine please, as that may make a big difference to what the problem may be.

Without knowing what machines it is, I can ask, does the hand wheel turn ? Does the needle move at all ?

Check that the throat plate is the correct one for the stitch you're doing and has not been raised. Check you have not set for zig zag stitch ( wider stitch width ). Stitch width too wide may put needle out of position so it can't do down.

Older Elna machine-black stitch discs, how do I use them


These discs are either single or double discs, the doubles give forwards and backwards movement by the feed dogs moving the fabric as well as side to side movement of the needle. This gives you the "Supermatic" stitches, revolutionary in 1952 when Elna developed this technology.

I'm assuming that you have a Supermatic (green) or Star Series SU (white with blue top) Elna model? your model will have a code number on the side plate by the power point, it may be 62 if its a Star, there is some variation in how you select the automatic stitches between these models but the basics are similar.

Start first by turning the stitch width selector to zero and stitch length selector to zero.

You need to insert the disc into the Elnagraph carefully, lining up the dot marking on the disc with the finger within the elnagraph, there is a little hole underside of the disc where this finger goes into to lock the disc in place. You now turn the stitch selector to "A" for automatic, and turn the stitch width to 4. Always turn your dials back to zero before removing the disc as there is a little feeler that swings over to "read" off the disc and you won't want to damage this.

The very early Elna supermatic take a slightly different disc, the finger hole is slightly different to the later machines and they were removed using a little tool. Later models it got easier and you push the middle of the elnagraph silver ring to release the disc.

I hope I haven't confused you more, you may want to join the Swiss Elna user group called Elna Heirlooms under yahoo.com groups, its a very helpful group of members and you should find a thread on these machines there.

The 6 built-in stitches (such as blind stitch, darning stitch, etc.) are not working, they only just do the basic zig zag stitch. Also the cams for decorative stitching do not work either. These are all...


I have the same model, have you turned the first knob on left, the stitch selector, to the stitch you want? Then turn the middle knob, the stitch width to "4". Use the colour guide marks shown in the little picture on left of the knobs so you are dialing up the right settings. So for the zig zag, elastic blind hem, scallop, overcasting and multi-stretch stiches, 1-6 on the diagram you'll be setting the left knob to 1, 2, 3, 4, 5 and 6 respectively and the stitch width and length knobs to "green", you can vary the length and width to suit what you want.

Then for the cams, you need to set everything zero, turn stitch selector to 7, the cam setting. then turn the width to orange again (3-4) and the stitch lenth selector to the orange setting, right around the knob. This engages the "Elnagraph" the device under the flap on top of the machine to read the discs. Basically the green stitches the needle is swinging from side to side while the feed dogs move the fabric forward, making your zig zags, blind hems etc.
But when you engage the Elna graph, the machine matches stiches by moving the fabric "forward and backwards at certain times, while the needle does its thing from side to side. This is what makes elastic or stretchy type stitches because you are putting "stretch" into the seam by sewing forwards and backwards.

Please note: always turn your stitch width and length back to Zero BEFORE you make any changes to the left knob and select a new stitch as this saves on wear and tear to the moving parts in these wonderful machines.

I do hope this assists you and I haven't just told you stuff you already knew!

My singer 7444 makes beeping sounds when operated, the machine fails to start.


Ensure that your stitch width and your spacing are set to a green-light setting. Also, ensure that your stitch wheel will operate(It will lock in the case of a jam.), and check to see that the stitch you have selected is compatible with the kit load you have onboard, i.e. for buttonholing, ensure you have the automatic buttonhole foot attached and the buttonhole lever down. In all other stitches, ensure the buttonhole lever is in the full up position. 

The 7444 Precision is a "Smart" machine, and will not allow you to attempt a stitch that simply will not work with the wrong stitch spacing and width settings applied. Move the sliders slowly until each one lights up green, or at least does not light up yellow/orange at all.

I want to know which knob I use to make the stitching narrower


there are generally two variable controls .. one adjusts the stitch length (distance between stitches measured in stitches per inch) ... the second is stitch width .. that adjusts how far the zigzag moves left and right .. thats usually just a number from 0 to 10 or so .. 10 would be maximum width .. 0 would be used for straight stitch ..
so you need to adjust the stitch width control to make the stitching narrower .. the controls are called different things on different brand sewing machines .. if you have the brand and model number then there may be instruction booklets available ...

Proper Settings


A good standard tension setting is usually around 4.5.
If you find it to be looping on the bottom, raise your top tension. If it's pulling bobbing thread to the top, lower your top tension.
For straight stitch, your stitch width should be set to zero, although on some machines (and I believe your Baby Lock to be one of them,) the stitch width setting will change your needle position.
Stitch length is simply a matter of preference.

Changing stitches


You probably have not adjusted you stitch width and length.
Also a manual for this machine is currently being sold on Ebay for $4+. Probably would be a good investment for you.
