Because the slides can break easily.
Why should you watch from the slide before you lower the objective of your microscope?

What objective must be in place when you remove a slide or place a new slide on the stage of your scope?
The lowest power objective lens should be under the tube. This provides clear access, prevents accidents, and lets you locate the object and reposition the slide as needed.
