Bernina 830

[bunny9]

Once again I have done it to myself. I was sewing along nicely when I needed to change my thread colour. I know to put the bobbin in first & checked that it was threaded properly. Next I threaded the upper thread. When I began to sew I got the error message. So I opened the bobbin area & sure enough the upper thread had wrapped itself around the hook area & bunched up. As I began to unwrap it some of the thread broke off & now I can't get it out. I have tried unsuccessfully several times to insert a new bobbin & top thread to continue my sewing. Do any of you have a tip on how to get the errant thread out of the hook system?
Thanks
Barbara

Try to oil it more and turn it with the hand wheel away from you a few times. Sometimes the thread will reveal itself and you can grab it with your tweezers. I hope this helps.

Oh, I feel your pain !! :cry: Take a few deep breaths and as Norma said,keep turning forward and back..
use a very bright light and maybe a few well chosen words....mine won't be printable ! :lol: :evil:
Good luck !!

Thanks Ladies. I will try your suggestions & let you know.

On my old Bernini you could remove the bobbin race :?

One more thing, but that has to be done before you get all the thread in the bobbin :cry:
Do you thread the machine slowly? When we thread it in the first eye, you have to wait until the light in the threader button goes on before you lay down the thread in the rest of the path. The computer has to be ready and I think the tension disks open while the light turns on.
Maybe this could be your main problem for the thing to happen.

Barbara, if your question is how to get the garble of thread out of your hook on the 830, towards the end of 2010, Bernina came out with a special accessory kit for the Bernina 8-Series machines. It was free of charge to anyone who had purchased a machine prior to that date (to be obtained from your dealer) and the accessories in this kit were part of the the package if you purchased a machine after that time. In any event, the kit contains, among other things, a hook cleaning tool. It's a flat, stainless steel contraption with a hook at the end of it (almost looks like the bottom part of an anchor). Its purpose is to slide into the bobbin case so that you can pull out any extraneous threads that might have gotten caught in the hook but are not visible to the eye. If you don't have it, the bar code number on my kit is 033595.70.00, perhaps your Bernina dealer can help you get one. If you have one, follow the instructions carefully, it's not difficult but requires knowing what you're doing. I looked for a video on line but could not find one. Nevertheless, hope this helps put you in the right direction.

Thanks Renata, I do have the tool to which you are referring. I am desperately looking for a video to see how to use it properly as I know it should do the trick on that little piece of thread which is teasing me.

Barbara,
I went searching for a video but had no luck. I do have the instruction booklet that came with my kit though. If you have that and you follow the English language instructions and go to the back flap of the booklet for photos. it is pretty self-explanatory. If you don't have the booklet, here it is:



Hook Cleaning Tool

IMPORTANT:
This tool may only be used for the application described!
Cut threads close to the stitch plate and remove the sewing project

Preparation:
- Remove presser foot, needle and stitch plate
- Open the bobbin door, the hook will swing out.
- Switch sewing computer off.

Procedure:
First use tweezers from the standard accessories to carefully remove the visible threads from the entire hook area (Fig. 10).

Turn handwheel to bring hook into the position shown in the picture (Fig. 11).

Carefully insert the tool into the opening, then pull the threads up and out by moving the tool sideways and upways (Fig. 12).

After removing all thread bits, lubricate the sewing computer, then switch it on and close the bobbin door.

THAT'S IT FOR THE BERNINA INSTRUCTIONS!

A few comments from me:

If picture 12 is not clear, when you turn the handwheel, the hook has to be leaning forward enough that you can see where to insert the tool. Notice on Fig. 12 where the two metal pieces cross: your tool must be inserted to the right of that. You will go down straight with your tool and it should go down smoothly. If not, you know you're not in the correct place.

Here is a photo of my machine, with the hook leaning forward (I turned the handwheel to get there) and the tool inserted.



Once the tool in inserted, you gently swing the tool to the left and to the right to see if it "hooks" a piece of thread stuck down there and then gently pull up to get the thread out.

If nothing comes up, then the thread is stuck somewhere else OR that might not be the problem.

Hope this helps! Wish there were a video! Let me know how it goes.

Looks like a dandy little tool ! I will ask for it next visit to the dealer ! Happy 4th all !!

Renata, that's a very good explanation on how to use the tool. I don't have the instruction booklet on it because I bought my machine second hand and didn't know I was missing it, so THANK YOU!

[Renata]

You're most welcome, Norma1 Let me know if you have any questions regarding its use. I've used it often enough to be comfortable with it but have not needed it in a long time... knock on wood! :lol: When sewing or doing FMQ, if I make sure to bring the thread up from the bobbin and hold it while I make the first few stitches, I never get garbled thread in the hook. I have also learned that, when you bring up the bobbin thread, always use the side of the foot pedal where you press down with the heel to bring the needle down and then up again, not where you press the foot pedal with your toes to make the machine run. This feature of the 8 series machine ensure synchronization between top and bottom threads so that you do not get garble.

[Zarah]

Thanks a lot, Renata. I haven't had many problems either. The way you describe is the one I use. Hooray, not a new habit to learn here :lol: :lol: :lol:
I just love my machine. I really feel I can do all that I want with this one.

I finally got the peace & quiet to work on the machine & success!!! Thank you so much, the little tool worked beautifully using your instruction ( your picture was fabulous). There was a little ball of thread that was causing all my problems.

However, I think I was a little too enthusiastic & the bobbin popped out a bit too far. Any ideas how to seed it properly again? :?:

Not sure what you mean, Barbara, but I would have to assume you are referring to the oval-shaped spring that you push your bobbin against when you insert the bobbin. If that is the case, I can't help you because mine popped out completely and I had to ask the technician to reinsert it. However, in the Bernina Corner of the Forum there was a discussion under the rubric of Flat spring behind bobbin 820QE. This might help you solve your problem. If that's not what you're talking about, please help me better understand what you're referring to.

Glad to know you were able to remove the garbled thread from your bobbin area. Amazing what a difference a little excess thread can make...
