I've working with a used Toyo 810M for a few months now and have been figuring out how everything works. In the process, a few quirks have revealed themselves.

It seemed to me that when the back and front standards are in their default 90 degree positions they are not exactly aligned. I picked up a hotshoe level that confirms that, though I'm not sure how accurate it is. Does anyone have any experience changing the default alignment on either the front or rear standard or is this something best done by Toyo?

Also, the knob that locks the front standard is really hard to loosen after its been sufficiently tightened to prevent movement. Is that normal? I've had to use pliers a couple of times.

Lastly, how do you adjust the infinity stops on the camera? I can't seem to slide them.

Thanks for your input!
