    KHB Photographix is the Canadian supplier for parts, and the D2 manual is available for $10: http://store.khbphotografix.com/Omeg...er-Manual.html. Also you can email them with questions. I can;t find my emails from them from last year, but the gentleman who replied to me knows the machine inside and out. --FOUND IT: Kevin Brown.

    My recommendation would be to remove the Aristo and look carefully at the carriage mechanism, or email KBH.
    Yep, I think there’s some major malfunction somewhere. I’ll contact KHB. Thanks, Philip.

    does the D2 have a locking knob on the bottom that needs to be loosened before raising the head ? on the D5 it's on the bottom of the carriage, facing user, below the elevation crank.
    notch codes ? I only use one film...

    Fred, yes, it does. It’s loosened, but the head is still frozen in place.

    There are 4 rollers riding between the column and the carriage, they look like small train wheels. Check those for alignment.

    I think I see what you’re talking about. On one pair of rollers, one turns freely against the column, while the other is stuck and won’t turn. Same for the others.

    Sounds misaligned, it should be fairly easy to put them back on track.

    Best way to work on it would be to set it on a table allowing access from all sides.

    I had to double check mine to confirm, the shafts that the guide wheels are on
    are off center drilled, so the become an eccentric shaft.
    You can loosen the screws on either end of the shaft and rotate the shaft
    so the wheels make contact with the rails, there is a hole drilled thru the shaft
    just for that purpose ( stick an allen key in it to act as a handle to rotate ).

    Just make sure the lamp housing and condenser are removed.

    Thanks, Jim. I appreciate it. I’ll give it a go.
