because you can get it dirty, or you could move the object being viewed to a bad position.
An objective lens should never touch the slide because it can damage both the lens and the specimen. It can also result in potential contamination and distortion of the image being viewed under the microscope. Keeping a small distance between the lens and the slide allows for proper focusing and prevents scratching or smudging.
Using the coarse adjustment knob on high power can potentially damage the microscope or the slide being observed due to the high magnification and close proximity of the objective lens to the slide. It is better to make coarse adjustments on low power to avoid hitting the objective lens against the slide.
The objective must be in the upper position when removing or placing a new slide on the stage of your microscope. This prevents the potential for the lens to hit the slide and possibly damage both the lens and the slide.
Removing slides with a 100x objective in place can damage the objective lens or the slide, as the lens is very close to the slide. Additionally, there is a risk of dropping or mishandling the slide when the objective is at 100x, causing potential damage to both the slide and the objective lens. It is safer to switch to a lower magnification objective before removing the slide.
The objective lenses should not touch the slide because doing so can lead to scratches on the lens or slide, affecting the quality of the image. Additionally, touching the slide with the objective lens can potentially damage the specimen being viewed. Maintaining a small distance between the lens and the slide ensures proper focus and clarity in the image.
Do not allow the high power objective to tough the lenses
so the objective lens will not touch the slide.

Keeping a small distance between the lens and the slide allows for proper focusing and prevents scratching or smudging.
Turning the coarse objective knob downward can cause the objective lens to come in contact with the slide, potentially damaging both the lens and the slide. It is best to always start with the coarse knob in the upward position to prevent any accidental collisions.
start on the lowest objective
Your hands should slide around the wheel and never allow your hands or arms to cross.
Using the coarse adjustment knob on high power can potentially damage the microscope or the slide being observed due to the high magnification and close proximity of the objective lens to the slide. It is better to make coarse adjustments on low power to avoid hitting the objective lens against the slide.
The coarse adjustment knob on a microscope should never be used with the high-power objective lens. This can cause damage to both the lens and the slide being viewed. Instead, it is best used with the low-power or scanning objective lens for initial focusing.
The objective must be in the upper position when removing or placing a new slide on the stage of your microscope. This prevents the potential for the lens to hit the slide and possibly damage both the lens and the slide.

Movements viewed through the microscope are exaggerated quite a bit. As such, it's best to attempt to line up the object on the slide by looking at the slide directly, rather than through the objective.
