shimano 600 sis shifting

So I'm new to this forum and found tons of info about the shimano 600 sis shifters. Only thing I couldnt find is how to change them from index to friction (or vis versa). I took it apart but could see anything that would change the shifting mode. I also try to turn the ring on the outter part to friction or index but it doesnt really turn easily. Any info would be helpful. thanks

strange, all the SIS i have seen has the friction - index positions clearly indicated with arrows. If it's not turning easily I suggest cleaning be careful with lubing though, a loose shifter may generate unwanted shifts.

Most down tube indexed shifters can easily be switched from indexed to friction and back again simply by flipping the switch from indexed to friction. Nothing to it.
