I'm with JRIowa and BigB. The Bridgeys at the old shop were sans power drawbar, and I'm still programmed to run them.
The Bridgey I run at the new shop has a power drawbar, but I still catch myself grabbing the wrench from the turret bolt that that it hangs on to give the drawbar a rap.
Probably doesn't help that my own '57 J head is wrench drawbar, and I exercise her regularly. Old habits die hard (says a 31 year old LOL).
From my Bridgeport manual:
'Drawbar has 7/16-20 right hand thread, and should be tightened by hand with normal amount of pressure using wrench furnished with machine. To loosen collet, back off drawbar and if collet does not open immediately, give knob on top of drawbar a slight tap'.
A person does not have to read into it very far to realize they meant the "tap" to be with the "Bridgeport wrench".
You can interpret it how you want, but the wrench is already in your hand, in close vicinity to the end of the drawbar you just loosened it with. Thinking they would have suggested a lead or brass hammer in the literature as the alternative, but they don't.
The wrench makes sense.
