SOURCE: Bernina 730 Can't open top cover !

The problem is that of a stuck piston detent on the pattern selector support that snaps the top cover closed.

  1. Open the light cover
  2. Apply pressure with thumbs on the bottom edge of the top cover on both the right and left sides of the cover. The cover should pop up...Too much pressure on the left side, (if this thing is really stuck) and you might break the top cover at the thread tension slot. Be careful here....
  3. Add a drop of acetone (fingernail polish remover) to the piston detent and work it free by pushing it back and forth. Avoid getting any acetone on the painted surfaces of the machine.
  4. Continue to work free, repeating with a few drops of acetone, and wipe clean. Don't oil this part. It was a petroleum product combined with a galvanic process (aluminum and steel) that caused the problem in the first place, not to mention age.
  5. Use DTE Heavy Medium oil rather than a white or clear oil when you lubricate your machine. White oils are unstable and will oxidize (decay) much more quickly. Also avoid 3 in 1 oil and stuff like WD40....very bad....
  6. Oil 1/2 a drop on those prescribed areas. Too much oil is more harmful than not enough....
  7. Contact your Bernina dealer for this oil.

SOURCE: My Bernina 730 record can only run the zig-zag

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...

Stitch selector knob on bernina 600, not Deco, is stuck and cannot select needle position, However the width of stitch part of the knob is working.This knob has 2 parts, needle position and width control


Your machine (Bernina 600 Record) has most likely frozen (seized) due to lack of regular maintenance. Don't panic. It can be fixed with a lot of elbow grease, good quality oil and a hairdryer. The following method has resurrected several Berninas I've picked up as "nonworking."

Bernina 730 how do I change feed dog pressure it is way to high not touching fabric when down??? Help please


There are actually two Bernina 730 machines (confusing, huh?). One is the 730 Record from around 1960. The other is the more modern 730 computerized model made in the 21st century.

The 730 Record has a hidden pressure adjustment. Lift the top cover and locate the screwhead on the very left side (left of the takeup lever knuckles). This screw loosens or tightens the spring that applies pressure on the presser foot.
The manual can be downloaded here, although it does not show the pressure adjustment:
BERNINA Sewing Systems

On the computerized 730, the pressure adjustment is on the screen (pg 37 of the manual):

Bernina 730 Record Service manual


Service manuals are difficult to find for most sewing machines, which Bernina is not an exception. However, there is a Yahoo Group called "BerninaThirtySomethings" that has conversations, documents, photos, etc. for the vintage Berninas including the 730 Record. You can join the group (must have a Yahoo email account) and download a variety of documents including a "Setting Manual" for the 730.

How do I keep the walking foot from unscrewing the needle holder on my bernina record 730


Tighten your needle with a screwdriver, instead of finger tight. If that continues to happen, take your walking foot back. That is not normal, and could end up injuring you or damaging your machine. Good luck!

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.
