Bernina 640-2
#21
Oh my, I would love a copy of manual! I recently became the new owner of 2 Berninas. Bernina number 1 is a 530-1 record beige in color with serial number 5934318... Bernina number 2 is a 640-2 favorit avocado color with a serial number 54002003. i was only given the manual to the 530-1 record...I am unable to order a manual for this 640-2 due to the rarity.
The manual is the one for the 540-1 and 542-1, which is identical to the 6 versions (I checked mine against the low res online sample for the 600 versions) and then got Bernina's permission to scan and share it. The lady from Bernina said to share with anyone who needs it.

I've a few higher res versions but this one is only 4MB.

What a great machine!
Unsticking the needle position knob is hard, but do-able. But you can't pry the knob out, because it can break. You have to loosen the insides, then push the post out from the inside. There's a hex-head screw on the right side of the assembly that needs to be loosened. Clean up the old gummy oil, then put it back together. Then you have to be careful with the tracer pin. If you push the tracer pin in, it doesn't like to come back out, so use heat to loosen the spring on the tracer, before you try to work with it. Then dissolve the gummy oil inside the pin.

Yes, very identical... Only my little side metal plate at right side is unused (no cut out holes) and my turning wheel at right of her is shiney and new yet very vintage. Hello Candace, and I'm sorry that I chose to keep these guys. So te machine is from 50s' or 60s'?

You may try - https://www.alikati.com/Bernina_Inst...nual/index.htm but when you click on "Bernina 640-2 Favorit, 642-2" it will give you static, but it will download and looks like the machine that Candace posted.
