Mazak Slant 50 Gear Question

[tsaladyga]

I have a Mazak Slant 50 old Lathe with Fanuc 11T control I am trying to setup in Mastercam and I don't have the manuals for this machine. Can anyone tell me what the gear ranges are? I know there are 3 I just don't know what the cutoff for each range is.
Thanks,

Put the machine in each gear and run the spindle up manually until it tops out.
