How can I fix the operation of the hand wheel release for a Bernina 807 Minimatic?


Over time the oil in the machine will evaporate or denature, if the machine has not been well lubricated for quite a while, it is likely that the clutch mechanism has gotten dry or gummy. If you remove the small screw in the hand wheel release, you will then be able to unscrew the hand wheel release all the way. Under that there will be a washer with two or three bumps on the outer edge and two or three tabs on the inner edge. Pay attention to how this is positioned. Especially noticing if the tabs are facing toward the machine or away. When you re-assemble the clutch you will want to put this back on the same way. Once that is clear, you may remove that washer, and pull gently on the handwheel away from the machine. The belt is still on at this point so it will not come off all the way. All you need is to be able to see about a quarter of the inside of the inside of the handwheel barrel. Put 5-8 drops of white sewing machine oil inside the barrel and rotate the handwheel. As you are rotating slowly push the handwheel back onto the shaft.

At this point, it can be helpful to run the machine to distribute the oil and loosen that contact. You may find it helpful to hold onto the needle bar, while running the machine slowly to ensure that they machine is not running. Be careful as holding onto any moving part can be quite dangerous. Use extreme caution, or do not do this at all. After running the machine for a bit without the clutch system installed, the machine should be loosened up enough to function properly. You can check this by letting go of the needle bar and running the machine, The needle bar should not move. If this is not the case, repeat the lubrication process and run the machine until it is loosened up enough to work. Once the handwheel will run without the needle bar moving, it is time to reassemble the clutch system. Put the washer piece back on the handwheel the same way it came off. Them put on the handwheel release, and finally insert the screw. Test the fuctionality of the clutch again at this point. With the screw fully inserted, you should be able to loosen the handwheel release about 1/3 of a turn. If it is significantly less than this, try turning the washer piece 1/3 of a turn until it is right. Once you have all that working, you are finished.

This is a fairly simple task, but is hard to explain or understand in writing. If you feel uncomfortable with these instructions, I would recommend taking your machine to a certified BERNINA technician. You can locate a nearby BERNINA dealer at the link provided.

How do I unjam the gears in my bernina 830?


If this is a Bernina 830 Record and the handwheel is stiff or does not turn, about 98% of the time the machine needs oil. Another problem could be a cracked or broken gear (one or both of the white plastic gears in the top but unless you are very handy, your Bernina tech should probably take care of this repair.)

Mechanical machines need to be oiled regularly just like your car. If the machine sets in storage for a while or is used often but not oiled or cleaned regularly, the oil that exists in the machine will eventually thicken and acts like glue. (Sometimes you can see a dirty-looking dark gold or brownish goop which is usually old oil.) Then your machine is frozen.

There are quite a few oil holes (both in the top and bottom of a Bernina mechanical) that require periodic oiling (see your machine Manual). If the handwheel is frozen, buy a bottle of liquid Tri-Flow Synthentic Oil (from the hardware store) and put one or two drops in all the spots shown in the manual. (DO NOT oil the two white plastic gears or the metal CAMs!!! NEVER use 3-in-1 oil, cooking oil, WD-40, or a generic sewing machine oil from the fabric store. And do not put more than one or two drops of oil at a time as over-oiling will also damage your machine.)

Then, using your hand-held hair dryer, direct hot air into the internal part of the machine (top and bottom). The metal may become very warm to the touch. Then try to gently move the handwheel. Repeat. Even letting it set overnight may help.

Once the handwheel loosens, slowly hand-rotate the handwheel and watch where metal parts move against each other, put a drop of oil in each of those. Be sure to move the selector knobs and oil where metal moves against metal to keep those working.

To maintain your machine, a good recommendation is to oil every time the bobbin thread is changed, every 8 hours of constant sewing, or every six months if the machine is not in use. Use a good quality oil, ie Bernina oil for "mechanical" machines. When oiling, also be sure to brush out the dust and lint (especially around the feed dogs and bobbin works).

If the oil in your tube looks dark colored, throw it out and get some new. I've run across some old sewing machine oil in the can that looked like dark honey and stunk to high heaven. Get rid of it!

Treat your machine well and it will serve you well for many years.

Bernina Patchwork 140 handwheel is getting stiff to turn


A stiff handwheel can be a simple as a thread stuck in the raceway or as severe as a failed uppershaft bushing.

Using your instruction manual, perform the basic maintenance and see if that helps. If not, take it to a repair person for evaluation.

Needle wont go up or down


If the Handwheel (big knob) is moving but the needle is not moving, you need to engage the clutch ........depending on the model

- push handwheel in to engage, pull out to disengage
or
- if there is a smaller wheel inside the handwheel, tighten to engage, loosen to release.

BUT if all is jammed........

Check for threads that are jamming the motion of the hook around where the bobbin case is

If your bobbin goes in from the top, remove the needleplate and bobbincase remove thread jams by gently rocking handwheel back and forth until released.

Clean around the hook race with a rag moistened with methylated spirit, surgical spirit or similar, then reassemble.

If front loading, open the door for bobbin case area, release 2 retaining clips holding the collar on (take note of the position/orientation for when you re-assemble....even take a digi photo to refer to !?!).....
......then just do jam removal & clean out in much the same way as for the top loader.

In all cases, don't force too much or be too brutal, gentle and patient works best, try to judge where the jam is caught and work with it slowly......you may need to cut jammed threads, just ensure all are removed before you re-assemble.
