This wheel does seize over a period of time.Remove the top cover so that you can see the wheel. It can be unseized by spraying a mixture of 20% ammonia to 80% water under the wheel. Let it sit for 20-30 minutes, spray it again and then turn it with a pair of pliers. Do NOT break it!! use a soft cloth around it if you want to protect the wheel from scratches.

How do you adjust the tension control on an Elna lotus SP

The tension dial is on the front of the machine right above the needle. The higher the number, the tighter the tension is applied to the top thread. HINT: When threading the top thread, ALWAYS RAISE the presser foot throughout the entire threading process. This allows the thread to seat completely in the tension disk. Tension is correct when the top and bobbin threads meet in the middle of the fabric.

I have an Elna SU. I cannot get my cam stitches to work....what could I be doing wrong? I have followed the manual.

If your machine is mechanical, not computerized, it probably needs a thorough oiling with fresh good quality sewing machine oil. The old oil has solidified over time and locked the moving parts in place.

Wheel on right side that controls the needle up and down is very tight...

It was working now it seems to be frozen the needle part wont move

Elna SU needle position lever is very stiff

this is probably due to lack of use and just stiffening up of this lever, best thing is to take off the top cover and get some triflow oil into the lever area, then try to work it back and forwards. First though, always set the stitch length and stitch width dials to zero before you try to move the needle dial, this applies to changing the stitch selector too, always turn width and length to zero first to avoid wear on these parts internally.

If you are happy to delve a bit deeper into your machine internally you might want to join the Yahoo group called Elna Heirlooms where other Swiss elna owners share their love and knowledge of these machines, there will be message thread on this issue there for sure.

Stiff wheel

My model list tells me this is the Star Series SU model, white with a blue top. These were made between 1964 and 1978, so getting on for 50 years old. I am assuming that the fly wheel wont turn at all for you, when machines are left for long periods any lubrication internally dries up. You can try to rectify yourself if you are patient, need Tri-flow Oil (preferably with a long neck applicator so you can get into the little spaces), a special lubricant which also contains a solvent, and a hair dryer to add heat. You will need to take off the top cover (two screws) to gain access to the main shaft and needle swing bearing. Also the free arm top plate should be removable with a single screw. Then get into the machine and clean with a small brush any visible lint or gunky build up on shafts, lubricate, then apply heat to the metal parts and wiggle to free up. Expect to spend some time on it, before you'll get things to free up. The needle swing bearing, the arm which holds the needle often seizes up too so straight stitch will work but no zig zag. You might want to join the Yahoo group Elna Heirlooms, lots of Elna lovers there who share their knowledge.

Needle position wheel on Elna Super bought in 1969 won't move

I suspect your Super needs some degunking internally, the old dust,, fluff and oil dries up inside and goes hard and this can eventually gum up unused parts. You could take off the top and have a look, usually a couple of screws holding down the top blue cover. Use a cotton bud and denatured alcohol and clean up around the needle centring wheel internally, cleaning and some gentle movement may free it up. Mary, you may also like to join the Elna Heirlooms Yahoo Group, lots of Swiss Elna owners share their love and knowledge for these vintage machines.

I was going to direct you to the website which had lots of Elna instruction and service manuals including the SU but today its links seem to be out of action. It may come back to life so worth checking another time.

In the meantime, did your repair shop actually service the machine or just pull the top cover off, put in oil and tell you that's it. There are still Elna trained technicians out there who are familiar with the older Swiss made machines and its probably worth trying to find one if you think the service centre you've visited hasn't actually addressed the issue.

The other option is if you are in the USA, contacting White Sewing Centre and maybe sending it to them to be serviced. LInk is

Or if you are technically minded yourself, you could join the "Elna Heirloom" group on Yahoo and then ask the other members there for help, there are lots of Elna lovers with models much older than the SU there who lovingly keep their machines running and share their knowledge. Just be clear as to whether yours is a Star Series SU (white with blue top) or Air Electronic SU (if you look on the id plate of the machine there will be a 2 digit code either 62 or 68.

I hope this helps you a little, I'd certainly persist with it if I was you. I just purchased my second SU 2nd hand after buying a new model of another brand 5 years ago and being quite disappointed with its performance, particularly with heavy jobs.

Needle position wheel is stuck

Remove the top cover. Note where the shaft of the the needle position wheel enters a metal casting under the wheel. Old oil deposits gum up the shaft. Heating this area with a hair dryer usually frees up the shaft. Be careful you don't use too much heat that would melt the plastic wheel. Lubricate the shaft with tri-flow and work it in by turning the wheel while it is warm. If it sticks again after it cools, repeat the process. It may take several hours or days for the tri-flow to penetrate and free the wheel up.

Old Elna SU (blue on top with black 'Elna' logo)

You take the thread down the left side of the silver wheel and then gently tug it upwards so that it clicks into the wheel. Then pass the thread through the rear of the thread take up lever(this should be raised), from left to right. Then take the thread down and slip it into the thread guide, down slip into the needle clamp and then thread through the needle from front to back.

Have a 1970's elna su supermatic but cams don't work

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!

I have and Elna su sewing machine and i can't get it to zig zag. Please refresh my memory on the settings i should have it on.

Depends on which SU you have, but you need to move the stitch selector to Zig Zag, then set the stitch length to 2.5 and the stitch width to at least 2.

On the earlier models the stitch selector is a wheel inside the flap on the top of the machine, on the air electronics, it is a coloured dial.

If this doesn't help, check if you've inadvertently moved the needle position to the side setting.
