"Do not force it" applies to anything. "Don't alter the shutter speed on a un-cocked camera" is generally untrue - you may lose or mis-expose a frame on cameras using a classic Leica style cloth shutter, but that is the worst that will happen, even if something appears to break in that context, it already was broken. Nor is the inverse any truer - you cannot set some leaf shutters past some internal thresholds if the shutter is already cocked, but only forcing them would damage the shutter.
