How do I get my Elna 7000 to sew as when I thread the needle and start sewing - the thread is somehow pulled out of the needle?

You should probably find an owners manual. Search for:

Make Model manual
(however, Elna manuals are seldom free)

IMPORTANT TIPS:
ALWAYS RAISE the presser foot when threading the top thread! Install a brand new needle at least every 8 hrs of sewing or whenever it strikes something. AVOID old and bargain bin threads.

How To Thread An Old Elna Sewing Machine

Elna Threading Instructions

..

Install a brand new needle.

Remove the top thread from the machine (ALWAYS cut the thread at the spool, raise the presser foot, and pull the thread down through the needle eye.)

ALWAYS RAISE the presser foot and rethread from the beginning. Verify the thread path is correct.

If it still does not sew properly or sounds clunky, take it for service. It could have been knocked out of time or bent something.

increase the needle thread tension

The top thread breaks
1. the needle thread is not threaded properly
2. The needle thread tension is to tight
3. The needle is bent or blunt
4. The needle is incorrectly inserted
5. The needle thread & the bobbin thread are not set under the presser foot when starting to sew
6. the threads were not drawn to the rear after sewing
7. The thread is either to heavy or to fine for the needle
8. Try a different spool or cone of thread

try changing the needle
rethread the machine top and bobbin
here is a link for a manual if you don't have one

http://sewusa.com/Sewing_Machine_Manuals/Elna_Manuals/7000_Instruction_Manual.htm

try a different bobbin incase that one is warped
it's also possible that the machine could need the timing checked

Try loosening the tension and pulling a longer string of thread. Also, if the needle is not at the highest point, when you start sewing, the thread will pull out.

Have you changed the needle and perhaps put it in backwards? this would prevent stitches from forming as the rotary hook goes around.

However, worst case, would be that the timing is out and may need to visit the mechanic to resolve if this is the case.

YOu can down load a manual from here http://www.arizonaexpressionz.com/elna_instruction_manuals/Elna7000.pdf

Just remember to click the bobbin thread into the tension device correctly and hold the two threads behind the pressure foot when you start each seam - Elna top loading bobbins give great stitch quality but you just need to keep stray threads out or they'll jam up.

Also, you must use the Elna plastic bobbin that the manual specifies for this machine - the 5000, 7000 and 9000 were Elna Tavaro Switzerland's first foray into computerised machines and first released in 1986.

Also, please check the manual when you go to buy twin needles, there are two types now as computerised machines usually need the twin needles offset from the shaft position. They have red or black plastic block between the shaft and the twin needles - I think you need the red ones but just double check the manual to make sure. And you can't do all the wide stitches with a twin needle as it will strike the foot.

Hope this helps a little.

thought I had a manual with an image of this but can't find it.

But pretty simple.
Place thread onto one of the spool pins at the back right, and pull thread across to the left and around the white blob on top of the machine head then back to the right to the little thread eyelet, down through this and down to the thread guide taking thread around it from the right and back up on the left side, back up and through the thread take up lever, then down again catching behidn the little thread guide, then to needle bar thread guide, then to needle eye.

ALWAYS HOLD THE two threads firmly behind the pressure foot when you start sewing - Really important.

Always wind and insert the bobbin with the holes on top, smooth side downwards. Place bobbin into bobbin holder and take thread take towards you and into the tension spring groove, pressing down on the thread with your finger until you hear it click into the tension spring. pull back the other way to check it is in there, if it comes out, do it again.

Bobbin will rotate anticlockwise when you pull the thread.

THen put needle plate cover down and draw bottom thread to the top using flywheel or the needle up/down button on these lovely machines.

Hope this helps, if not post again and I'll dig out images from my SU manual.

just wonted to see how much these elna 7000 are running now i have one but i just wonted to see what its worth now
