Question about Bernina Virtuosa 160

1 Answer

Bernina 801 Sport

I was given this (noncomputerized) machine which was unused for many years.  It sewed well and then just froze. Obviously, the mechanical parts were dry from non-use and not being serviced.  My husband oiled it and got the mechanical parts in alignment.  Now the needle ( unthreaded) goes up and down easily and quietly and does NOT strike the bobbin.  However, when I lower the threaded needle to pick up the bobbin thread, the upper thread completely  loses it's tension and will not pick up the bobbin thread. I have the bobbin installed correctly and the upper thread threaded correctly.  The tension is set at the standard setting.  
What should I do now?  Thank, Betty in Colorado mountains

    The machine is threaded correctly, new needle, same thread top and bobbin, and lower tension is too loose. I tightened the upper tension and there is no difference

How do I remove the top on a Bernina 807 in order to chnage th elong belt ?


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.

I have a bernina Sport 801 and my bottom tension is off. I'm not sure how to fix this. Adjusting the tension setting doesn't seem to work.


On the bobbin casing is a screw to adjust bobbin tension when upper tension will not solve the problem. Check your manual for location of the screw.

I have a bernina sport 801 and the fabri feeder


There is a small knob on the lower part of the main body under the stitch length lever. This controls the feed dog up or down. Make sure that it turns easily and fully to both positions. If it does and your problem persists, the feed dog height adjusting point is probably loose. A knowledgeable repair person needs to look at it. It is not a difficult repair, but several approaches need to be taken.

I have bernina sport 801 machine and need to know


You can oil any two metal parts that move togeather or through each other. Do not oil bearings and do not oil gears. Do not use 3 in 1 oil or WD-40. Use regular sewing machine oil.
801's were made from 1979 - 1982. The way Bernina dated these on the machine is by the serial number. Your number would probably start with a 0 or a 1. 1970 is a 0, 1971 is 01, 1980 is 1, 1981 is 11, 1990 is 2, 1991 is 21 etc. etc.
