There may be a set screw on each of the cam sockets. Loosen them and then unlock the cams with the T wrench.
Mine was not indexed either. Before I removed the 3 Jaw chuck (factory installed?), I checked the runnout. Mine was acceptable, so I indexed the chuck with some number punches at that time. I then installed the faceplate and found the best clock position for it and indexed it as well. I have not installed the 4 jaw as of yet and I don't know if it will matter much where it is clocked on the spindle. Plus, I really don't know how to check the 4 jaw.
BTW, on my similar lathe, the tourque on each cam lock affects the runout. I have to "play" with the tightness on each cam while indicating the chuck in. So changing a chuck out in this lathe is not as simple as the cam lock system looks. I don't know if this is supposed to be this way or maybee this is a "feature" of these off-shore lathes.
But the indexing helps get me in the ball park quicker. I'm glad I did it.
That's my story and I'm sticking to it...
