Monofilament thread problem on a Bernina 820
I cannot get the monofilament thread to work in my new Bernina 820.
I am using the best thread and have tried setting the tension to looser settings. I am using the 75 or 80 Microtex needles and 50wt cotton thread in the bobbin. But it still will only make a few stitches before it begins to hang up and stretch to the breaking point.
The Bernina 820 does have a tall thread stand and I have used the net to help control the unwinding to no avail. I have discussed this with my Bernina dealer and they claim that they don't use the monofilament thread on the Bernina 820 because the arm is so long that it makes the thread tangle. I am really disappointed that I cannot use this machine with the monofilament thread to do the invisible applique.
I am able to use it on my old Bernina 1090 but not my new machine. I have searched the Bernina website and sent messages to them but have not responded or nor do they list any good advise that I haven't already tried.
Is anyone else having this problem with the Bernina 820? If so, has anyone found a solution to the problem?
Patty, I'm posting this question in hopes that a Bernina 820 user will respond with actual experience, but in the meantime, have you gotten...
A New Thread Lubricator Guide for
Series 8 Machines
This new 'Thread Guide Accessory Kit' is free from Bernina (Reorder # 033595.70.00 Location: B8903010201. "8 Series Kit for FREE" is marked on the box itself).
Installed near the spool holder, it adds an additional guide to tame unruly threads, as well as providing a sponge for thread lubricant. Check with your dealer for availability.
Intuitively, each thread guide adds a bit of tension to the thread as it passes through your sewing machine. I would expect to have to reduce needle tension further or increase bobbin tension to offset this additional guide.
Additional Research Reveals...
In researching information I've found, threading your machine with monofilament thread is a bit trickier than, say, a cotton thread. Bernina asks that monofilament thread be held tight all the way through to the white lips, only then can threading your sewing machine begin. Bernina also suggest to reduce your stitching speed to 1/2 or 1/4. (For machine applique, this is a good idea anyway, the zig zag is pretty small. It's faster to sew slower than sew fast and have to rip things out.)
If you are quilting with the BSR (Bernina Stitch Regulator) engaged, the manufacturer recommends these tension settings:
- Sulky monofilament: 1.75 - 2.0
- YLI monofilament: 1.75
- Madeira monofilament: 2.5-3.0
While you want to use the thread for invisible machine applique, these are at least indications of where to start testing the tension.
One quilter recommends using Superior Threads' Bottom Line in the bobbin with Superior MonoPoly in the needle, a 5.5mm throat plate, with bobbin tension two clicks right of normal.
Have you tried making any adjustments to your bobbin tension?
Increasing it would help counteract the higher tension created by the needle monofilament. (Both of the Superior Threads this quilters recommends are polyester.) Refer to your owner's manual for instructions on how to do this.
Other recommendations from quilters who've had problems with this machine include:
- Download any updates from Bernina as they are available. Many report the updates DO make a difference.
- Make sure your machine is on a very sturdy table. Any bounce will effect tension.
- Always clip your thread at the spool and pull the thread tail out through the needle. Just removing the spool and pulling the thread back through the machine can effect your tension.
- Try a separate cone holder for threads. YLI and SewArt monofilament are cross-wound onto cones. The separate thread stand gives them a bit longer to 'un-kink' before they get to the machine.

Patty, I hope one of these suggestions helps. These machines cost a pretty penny (lots of pennies, really). You are not alone with problems you've been experiencing.
