Page 8 Cleaning and lubrication The best way to remove lint from the machine is with compressed air. Blow all the lint from the machine. Remove all lint from the gears and again from the bobbin area and feed dogs. When oiling your machine, make sure you use a good quality oiler and clear sewing machine oil.
Page 10 Adjusting Tensions To check the bobbin tension, insert a bobbin wound with medium weight thread into the bobbin case. Remove the hook from the machine. Snap the bobbin case onto the hook. Hold the hook and bobbin case by the bobbin thread and jerk the thread once or twice. Page 11 Top Tension The top tension is controlled with the tension dial. Normal tension is when the indicator is centered.
After the bobbin tension is set the tensions should balance in the center of the fabric as shown. If adjustment is required, sew a test and turn the top tension dial until the right tension is achieved. Page 12 Hook Timing and Position With the hook in the race but the race cover not closed, set the needle position to the far left. Bring the needle to its lowest position. The tip of the hook should be 2. From the lowest position bring the needle up until the hook and needle meet. The tip of the hook should be just above the eye of the needle.

I bought it from two sisters that had to put their mother in a memory care facility. Neither one sews, so I benefited from that poor lady's misfortune.
It came complete with a full set of feet and all acessories and I truly appreciate this mechanical wonder. I'm finding it hard to justify having so many vintage machines when I can only use one at a time, but can't seem to part with any of them.
My problem exactly although I have managed to sell a few and re-thrift a few as well. I'm overcoming the addiction, gradually. I'm at the point where very few machines pique my interest. Wednesday, February 7, Bernina I've been hearing and reading about the Bernina for a couple of years.
