Bernina 930 Questions

I was fortunate enough to find a Bernina 930 Electronic machine at a yard sale. I've learned a lot reading posts by all of you 930 experts but still have a few questions.

My machine didn't come with a foot pedal. It's been sitting around for a couple of years because I couldn't afford to get the pedal. I just bought an original one on Ebay. The machine runs great but I can't get it to do anything but straight stitch. The part that holds the needle seems loose but it's probably just that I haven't studied the manual enough to know how to set it up properly. I'm planning to buy the repair manual. Does anyone do their own maintenance or is this something that requires a lot of expertise and specialized tools?

My machine has the number 03 83 on the inside back of the throat which I assume means that it was manufactured in March of 1983? Also, when the machine is running, the bobbin case makes a slight clicking noise as it moves. Is this normal or does it mean that it needs to be tightened?

Have you oiled it beyond the hook?

The Yahoo group Bernina ThirtySomethings has a lot of helpful info, including this oiling chart from their FILES section:



And check the the big, white nylon worm gear (visible from the open top) for cracks. This is probably the weakest part of the Bernina 800 & 900 series. Replacements are available.

Flip that top cover up, like shown in the post above. Look at your large white plastic gear about in the middle of it there, that is in front of the large all metal cam stack laying sideways in there. If that plastic is cracked, and then when you try to select the fancy stitches they do not sew out, possibly that why "maybe "it's not working for some of those fancy stitches. Just since once that cracks and until you get a new one, it probably cannot even sew those stitches. If it's not cracked, then maybe you just need to clean and oil your machine instead even.

Also I don't even think that large white plastic gear in front of the metal cam stack has to actually be cracked all the way through at all, for the fancy stitches not to work. Even if not cracked or just a little bit, if it has really separated and pulled away from the metal base it is supposed to be firmly attached to, it still a gonner then, as it would not even be able to move and turn and turn your metal camstack at all, to get any of those fancy stitches formed at that point either. So if you even turn the fly wheel by hand, and watch it at the same time, you would notice what was happening or not there with that.

If you are not getting any of the decorative stitches, then the furthest right lever on top is not engaging the mechanism properly when moved. Easy to check. Lift the top and move the lever forward and back. It should snap the mechanism into place with a sharp click. If it doesn't then lubricate the necessary spots and move the lever forward and back continiuesly until it clicks properly. Hope this helps.

PS When removing the top, push down on the screws and turn them half a turn counter-clockwise. They don't unscrew.

Curious, what does the 930 foot pedal sell for?
I have the repair manual for the 830 Bernina and there are only a couple things I will do, most all repairs take special tools and gages made for these machines and they are just listed by numbers. This is a fine Swiss piece of machinery and without the training and tools I would leave most of it to a factory trained person. Oiling and grease are an easy fix. The illustration shown is an 830 machine but oiling holes are the same on both machines.

Thank you all for your helpful replies and Sewandwrite for the photos. We took off the top of the machine. It looks fine to me. I don't see any signs of wear on the gears. Even with a flashlight and magnifying glass, I couldn't see any cracks. I think I'll attach a straw to my vacuum as someone suggested, suck out the dust and oil the machine at the points on the diagram. Hopefully that's all it needs.

I did notice that the wheel has a crack. I'm not sure if that will affect its function. I checked a few sites that sell Bernina parts but the hand wheel isn't available. Does anyone know where I can find one? The cost of the food pedal was $79.99 plus $10.95 shipping. It is in perfect condition. The aftermarket pedals sell for $149 free shipping. Thanks again everyone. I'll report back on how this works out.

Which Bernina shank adapter, #75 or #77, is required to attach a Greist Style #1 buttonholer to a Bernina 930 sewing machine?

I have the 930 and just looked at my adapters, one doesn't have anything listed and the other is #19. The adapters for the 930 need two prongs going up like the other feet. I googled the 75 and 77 and they look like a different configuration, but still seem to have the two prongs, newer style. I would make sure they would first work on the 930 machine. My adapters convert to be able to use a low shank foot, if the Greist buttonholer attaches to a normal low shank machine the Bernina adapter should work.
Old Style that looks like mine, can be purchased through Amazon.


Here are two links to how Bernina describes the difference between 75 and 77. You need to find out if the buttonholer will work with a standard low shank and then go with that one if it does.

77

75

I know this isn't telling you which one to buy but someone who has this buttonholer could tell you if it is designed for a standard low shank. 77 is for attaching short shank feet.

Thank you very much for your help... I have sent the question to Bernina to see if they can clarify which shank adapter is required for the application. :-)
