Restore & Upkeep of the Bernina 830 Report Stitching Machine



There may be a substantial amount of confusion as as to whether, the place, what with, and the way a lot to grease Bernina machines. Your proprietor’s handbook is indispensable on this regard. It not solely tells you the place and the way a lot to grease, but additionally which oil to make use of.

First, a phrase concerning the oil itself. The most secure oil to make use of is that which got here with the machine, or that which will be bought from a supplier. Bernina oil ought to say “Bernina” on the tube. When you’ve got any doubts, as an example you probably have bought a used machine and the oil is suspect, it is most likely a good suggestion to throw that oil out and get some extra. Bernina oil could be very gentle in viscosity, and is nearly clear.

The realm that’s most crucial to grease is between the shuttle and the shuttle race. (See house owners handbook) Oil this about each second time the machine is used for any size of time. Only a half drop will do.

Over-oiling simply makes a multitude. It is also a good suggestion to grease the pin on the shuttle that the bobbin case matches over, and a bit on the bobbin case latch.

Having mentioned the above about the kind of oil, I’ll say that I personally have used Singer model oil (discovered at any Wal-mart) with good outcomes. “Three-in-One” oil or any sort of motor or vegetable oil ought to NOT be used on stitching machines in any respect. I’ve seen machines just about ruined with the improper sort of oil.



A “burred” or blunted shuttle pont produces a wide range of signs. There could also be occasional or irregular skipping of a number of the stitches. Or, the thread might periodically shred and even break. Typically there will probably be small loops of thread on the underside of the material.

The “shuttle level” refers back to the space on the shuttle pictured beneath that’s instantly behind the needle. It’s actually sharply pointed so as to choose up the thread loop because the shuttle passes behind the needle. Due to the shut tolerances of the Bernina, or as a consequence of utilizing “knit” needles just like the Singer Yellow Band, or extreme pulling on the material as you sew, generally the sharp level turns into burred, blunted and even bent. This causes the thread to hold on the shuttle relatively than passing easily round it. The issue can generally be detected with the bare eye, however a surer methodology is to stroke the shuttle level high, backside, and sides together with your finger. Any burr or roughness will rapidly be detected.

If a tough spot is detected, often it may be smoothed, saving the appreciable expense of a brand new shuttle. I exploit a Dremel device with a rubber wheel however excessive care have to be taken to not blunt the shuttle level or change the fundamental form. A safer methodology is to make use of 600 grit or finer sandpaper, rubbing frivolously in the identical course of the shuttle level.
