Question about Bernina Bernette 75

My Bernina 730 record can only run the zig-zag stitch. The tech said the motor was "weak". Will replacing the brushes in the motor fix the stitch problem?

Sewing machines needs full service now and then (every 10 years will often do). The motor on the 730 series is actually as powerful as they get on domestic machines, and handles just about everything that fits under the pressure foot. Only if the machine has been used a lot over the years are the brushes worn down, but it might need new grease not matter how little it has been used. 

However, the stitch applications can sort of gum or clog up if the machine has not been used for ages. Take a look in the manual and oil ever point suggested every time you take out the machine. Try them now and then on slow speed, that might get every function to run smoothly again. 

This is as good a machine as any out there, favorably compared to any new machine under 500£. It sews perfect stitches on just about any material, and is well worth a full professional service (At a shop they will always recommend a new machine they want to sell you). All kinds of pressure feet and accessories are available in regular sewing shops and online.

Check with different shops for price on full service. This is a great machine what ever they tell you.

I have a bernina 730 and it does a fabulous straight stitch but it won't do zig zag or any ornamental stitches


Assuming this is the older mechanical Bernina 730 Record (not the new computerized model)...Sounds like your machine is seized due to dried oil.

Wheel on right side that controls the needle up and down is very tight...

I cant get my stitch Width Zig zag knob to turn om my bernina record 930. Any one have this problem?


Most likely because your machine has not been serviced (oiled & cleaned) in a long time and the old oil has turned to glue and seized. This is probably the most common problem with mechanical sewing machines. A mechanical sewing machine should be regularly maintained..ie every 40 hours of sewing use or at least every six months when not in use. You may want to take it to a Bernina service technician. Ask for a bottle of Bernina oil for CB hook machines and ask if they will show you how to oil it.

Can you use twin needles on bernina 1080


I have a Bernina 930 Record that will take twin (even triple) needles, so I don't know why your 1080 wouldn't. Just be sure your machine does not have the straight stitch plate on it, that your presser foot can accommodate zig-zag stitch, and that you carefully adjust any zig-zag stitch width so the needles do not hit the presser foot or stitch plate. I'd suggest installing the double needle and then carefully hand rotate the handwheel to see if the needles will hit anything. If you can make a full rotation of the handwheel without anything hitting, then slowly try it with the motor engaged.

Bernina 730


try changing the needle--one for the fabric being sewed
also the zig zag could have a worn or damaged gear or cam
or there could be a timing problem.

Have a Bernnina record 530. The zigzag will not work, just straight stitch on any width setting. all the other fancy stitches(1-12) work fine.


the cam or gear of the zig zag could be worn or damaged,, having the machine checked,, would tell you for sure what wrong with the zig zag..

Zig Zag Stitch not working


THis problem occurred as I was sewing on Neoprene. I was using Gutterman all-purpose thread and a size 80 needle. Tried switching to a size 70, then to size 90. Still unable to zig zag. After inserting a test sample of cotton, the zig zag worked perfectly, so I knew it was not a mecahnical problem. I switched needles again. This time to size 90 for stretch fabric. Voila! Problem solved.
