Setting the aperture as such is of no influence to the shutter of this camera.

Both, aperture and shutter, can be adjusted seperately, though they are EV-linked by means of an adjustable, springloaded lever. It is the aperture that follows the shutter. When using the EV-linkage one thus has to grasp for the shutter dial anyway. And as the linkage is very weak one has to press on that lever in order not to lose the linkage. (Another shortcoming of this camera.)

But AaTen is is right in that sense, that when you do as just described, and the shutter is already cocked, you could by means of trying to adjust the aperture get the shutter in that setting he described as harmful.
