AKAI 4000 DS reel-to-reel tape recorder SPEED change

to change the speed from 19 to 9 speed, you need to change the thickness of the main shaft, for this you need to unscrew the additional nozzle

That machine runs smoothly. I found one and it squeaks and screeches a bit, and it doesn't seem to turn off when I use the switch. Is the Shut-off switch only supposed to be activated when you are about to disconnect it? But not really turn it off by itself? or why does it remain "on" when I turn the switch off?
