How is it possible to replace the light bulb in the Bernina minimatic 807? I managed to remove the dead bulb, but cannot install the new one

How long since it's had a thorough oiling and cleaning?

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

Could also be the carbon brushes.

........Start by removing the bobbin and bobbin case.
........The old grease is most likely hard.
.........Open the upper and lower areas and clean up all of the grease. Real hard debrees can be removed with carburetor cleaner.
........While turning the hand wheel you can spray this on parts to loosen the grease. Use qtips to remove the debrees.
........Use qtips that have been sprayed with carburetor cleaner to clean the plastic where the dried grease and filth is at. Try not to use carburetor cleaner on the plastic as much as possible.
........When the cleaning is finished use sewing machine oil on all parts that are steel against steel movement. (Not plastic or rubber).
........ For plastic against plastic use lithium or 100 % synthetic oil. These can be used in place of the grease because they don't become hardened due to wear and time.

In my earlier response, you need a shank that is made for your Bernina 807 and Berninas made in that era. Only "Old Style" Bernina presser feet and adapters will fit your machine. No other brand will work, not Singer, not Janome, not Brother, nothing but Bernina Old Style. There are several Bernina old style presser feet. Look for presser feet with the number printed in black ink or presser feet that have the number stamped into the metal. Do not buy a Bernina presser foot with red numbers--will fit only newer Bernina machines.

If you want to use the Singer buttonholer attachment, it needs to be for a straight shank machine. You will need to have a Bernina shank adapter for your machine.
Bernina Presser Feet (down at the bottom of the page, click on the blue text that says "Bernina Shank Adapter" On the next page, scroll down to the last two items that indicate they are "Old Style." The first Old Style item is the shank adapter you would need to attach the Singer buttonholer attachment to your machine. (Am assuming it will work, no guarantees!) If it doesn't work, then you will probably not be able to use the Singer buttonholer with your Bernina machine.
This shank adapter would fit your machine:

If you are looking for a snap-on adapter, it needs to state that it will work with a Bernina Old Style machine, ie the old Record machines (930 Record, 830 Record, 730 Record, 707, 807 Mini, 630 Record, and 530 Record--or in other words, Berninas manufactured prior to probably 1996).

Bernina Presser Feet (down at the bottom of the page, click on the blue text that says "Bernina Shank Adapter" On the next page, scroll down to the last two items that indicate they are "Old Style." If you are looking for the snap-on, go to the very last item on the page (Old Style). This will fit your machine. Remember, if it says Old Style, it should work on your machine.

This snap-on shank will fit your machine:

Here is a kit of snap-on feet with shank (included) as well as the buttonhole attachment you were asking about:

Although, I believe you will be able to make only straight buttonholes with this buttonhole attachment.

Hope this helps.

V-Belt replacement 801/801 Up Machines

Only the belt cover needs to be removed for this belt change. This is done by removing the three screws on the end/belt cover. Loosen the 5mm Allen socket head screw below the step pulley to relieve the belt tension. Remove the lower motor belt. Lift the step pulley and slide off the hand-wheel, (assuming that you have already removed the release knob and clutch ring).



Additional top cover removals 807/801 Minimatic machines

Early 807 machines had two expansion nipples in the top cover that fit into receptor holes in the upper arm frame. Simply pull up the top cover.

Very late models may have a push button latch mechanism, same as on the 801 machines except those fitted with carrying handles, i.e. 801 Sport, 810 machines.

This is accessed by opening the light cover and finding an aluminum knob in the upper left hand corner of the upper arm frame. Push this in and the cover will release. Lift off the top cover.

sounds like there is a short in the wiring somewhere in the machine, it would be a good idea to have it checked

You might be able to find the brushes from AllParts. Good luck on the service manual. You might get lucky and find a book on ebay but it's not likely.

Try www.Sewingstyle.com. They carry a lot of parts for new and old machines. If they don't show it on their sight, drop them an email or call them. They may surprise you.

Good luck!

There isn't an automatic button hole on this machine. You can do it manually. Thread the bobbin thread as usual, but put it through the little hole on the hook in the bobbin case. Set the stitch length between 0 and 1, like a nice satin stich. Set the needle position to the far left and the stitch width to 2. Sew down the left side. Center the needle, set the width to 4 and lower the feed dogs, stitch about 6 stitches across the bottom. Then reverse the direction, set the needle to the right, stitch width to 2 and go back up the right side. Lower the feed dogs again, set a wide stitch and finish the top.

Another good option is to buy a universal presser foot shank from Bernina and then attach an old cam type buttonhole attachment from Singer. They make beautiful buttonholes and you can even do a keyhole button hole.

Oh my gosh--how simple it is:

However, perhaps the manual would be helpful:

https://www.google.com/url?sa=t&rct=j&q=&esrc=s&source=web&cd=1&ved=0ahUKEwjYqvrshIfRAhXj44MKHQ0TCEMQFgguMAA&url=https%3A%2F%2Fwww.bernina.com%2Fen-US%2FSupportData%2FOut-of-Print%2FBERNINA_807_810_817_manual&usg=AFQjCNFNJyvVESPeSjAOPQT2cX5Z3rclbw&cad=rja

While you have the machine open, it might be a good idea to apply a couple drops of good quality sewing machine oil or (better yet) liquid Tri-Flow Synthetic Lube to every place where metal rubs against metal. (Slowly turn the handwheel and watch the movement.) Also look for the oil port holes throughout the machine an apply a couple drops in each. Do NOT oil the plastic gears or belts!!! Also, move the stitch selector and feed dog levers and hit those with a little oil too. This will keep your machine happily humming!!! You'll probably notice how quietly it runs afterward!

Can any please tell me where I can purchase a manual for a Bernina Artista 200 Manual as I accidently threw my away.
