What you do first when you use a microscope you put the slide in. Then you focus the microscope. Then you look at the object you are supposed to or look at the object you want to.
Dropping the microscope or mishandling it can lead to damage, as well as using excessive force when adjusting the focus or moving the slides. Using improper cleaning methods or harsh chemicals can also damage the microscope and specimen.
it allows you to focus your lens on the pbject.

The basic requirement for you to see an object using the microscope is light. The amount of light will determine the visibility of the specimen.
Because It Could Blind You
To observe a skin cell at the highest magnification through a microscope, you should first place the skin cell slide on the microscope stage, focus the microscope using the coarse and fine focus knobs, adjust the light intensity, and then increase the magnification to the highest level possible on the microscope objective.
When using a microscope, it is generally recommended to avoid focusing too far upward because this can cause the objective lens to hit the slide or specimen, potentially damaging both. It is also important to focus upward cautiously to prevent overshooting and losing focus on the specimen.
Depending on the microscope the steps differ but assuming you are using a light microscope (the only microscope you will use before university). The microscope must be set to the lowest magnification with the stage set as far way as possible (the platform the sample is held on). Then using the coarse focus (the larger knob) bring the stage towards the lens while looking though the eye piece when the sample comes into focus use the fine focus knob (the smaller knob) to bring the image to optimum focus. When this is achieved increases the magnification (by changing to a stronger lens) and using fine focus continue to focus the image and keep repeating the steps till a max focus is achieved. If more information is need let me know as there are more complicated techniques but this should be enough for before a university level depending on what country you are in.
You can determine which hair is above the other on a microscope slide by adjusting the microscope's focus. The hair that comes into focus first is positioned closer to the objective lens and is therefore above the other hair on the slide. This difference in focus indicates the relative depth of field between the two hairs.
No, when using a microscope, you should focus away from the specimen initially by moving the objective lens upward, then slowly bring it down towards the specimen to avoid damaging the lens or the specimen.
The diopter ring on a microscope is used to focus the eyepiece specifically for each individual user's eyesight. It allows users to adjust the focus of the eyepieces independently to compensate for any differences in vision between their left and right eyes. This feature helps in achieving a clearer and sharper image when using the microscope.
