Always carry the microscope by putting one hand under the shoe-shaped base and grasping the curved stand that supports the tube and its lenses with the other hand. Everything should be in working order, clean and oil free of dust. If you have a slide with a prepared sample, place it on the stage of the microscope. To maintain the good condition of your microscope, first and foremost guard it from dust. Cover the microscope with a plastic hood when you are not using the instrument and always store it in its case. Clean the microscope carefully to avoid the scratch in the lenses. If some of the lenses have fingerprints, clean them either with lens paper or with some alcohol and a cotton swab. Rinse dirty slides and cover glasses in liquid detergent and warm water.
it is the COURSE adjustment knob
the first and foremost thing to know before you can use a microscope is how to use it?
This is the coarse adjustment knob. This should be used before the fine adjustment knob (the smaller knob) - which is for fine focusing.
It is the first knob you should turn to bring the object into rough focus, before tinkering with the finer tuning knobs.
You should first use the lowest power setting of a microscope to find an object and then center it within the viewing area. Then, when you switch to the next higher magnification, your target should still be close to the center and easier to find and focus on.
When viewing specimens or objects under a microscope, it should be set to a low power first. This allows for a wider field of view that makes an object easier to locate.
The lens that you should use to first look at a slide on a microscope is a low power lens then move on to a higher power for more clarity.
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 viewing specimens or objects under a microscope, it should be set to a low power first. This allows for a wider field of view that makes an object easier to locate.

Put it in a safe place. And clean it first
Always carry the microscope with two hands, one on the base and one on the arm, to prevent dropping or damage. When focusing, use the coarse adjustment knob first for large adjustments, and then the fine adjustment knob for more precise focusing.
the microscope
What was the name of the first microscope?
The first microscope was called the "single lens microscope" and was invented by Zacharias Janssen in the late 16th century.
