From my schematic set published by electronic technician magazine... I think this is real RCA service literature, just some of it is missing. This is for an 11, but it has the same set of controls as the 10 (at least in these schematics).
1) Set service switch in service position
2) Set kine bias and all screens to minimum (ccw)
3) Adjust red green and blue screens to point where beams just cut off
Note: increase kine bias only as required to support weakest screen adjustment
4) Reset service switch to normal
5) Adjust green and blue video drive for black and white picture

There is also a "long version" of this mentioned. The only real difference is you are just making a dim line when you set the screens rather than just cutting off the beams.
They also mention that if you have a replacement crt, and it happens to be one that green is the weakest phosphor rather than red, you should exchange the red and green cathode leads so the controls become "blue drive" and "red drive" and green runs wide open instead of red.
