Start low, and adjust UP. Otherwise you are in danger of moving the lens DOWN into the slide, breaking the slide, and maybe damaging the lens. Do not ask me how I learned this- OK?
Coarse wheel adjustment on a microscope refers to the large knob used to move the stage up and down rapidly to bring the specimen into approximate focus. It is used to make rough adjustments to the focus before using the fine adjustment knob for precise focusing.
I believe it's the coarse adjustment.
The microscope stage should be in its lowest position to avoid damaging the objective lens when you first begin to focus on an object. Begin focusing with the coarse adjustment knob and then use the fine adjustment for finer focusing.

You should always use the fine adjustment on a microscope when you are focusing on high-power magnifications, typically 400x and above. The fine adjustment allows for precise focusing, which is crucial for observing details without risking damage to the slide or the lens. It is also recommended to use the fine adjustment after initially focusing with the coarse adjustment to enhance clarity.
The coarse adjustment knob should be moved in a counterclockwise direction to raise the body tube.
The coarse adjustment knob elevates the microscope's stage up and down quickly. The fine adjustment knob does the same thing but more slowly and accurately. In other words, the fine adjustment knob should require more revolutions to elevate the stage as much as the coarse adj. knob does.

The coarse adjustment knob should be used first to bring the specimen into general focus. Then, the fine adjustment knob can be used for precise focusing.
There are two adjustment knobs (coarse and fine) on a microscope so you can move the stage at two different speeds. The coarse moves a lot per revolution, while the fine adjustment knob moves the stage at such small increments that it is nearly impossible to notice when looking from the side. The coarse adjustment knob should be used to get the stage closer to the lens only while you are looking at the microscope from the side. The fine adjustment knob can be used when you are looking into the microscope because there is a much lower chance of running the stage into the lens and breaking it.

First of all, one should never call it high power, it is morecommonly called the "high objective", yet that is not what this question is asking. To answer the question: You use the fine adjustment knob. This knob should be located near the coarse adjustment knob, on the opposite side of the microscope (at the same height as the coarse adjustment knob), or even as a separate knob protruding from the coarse adjustment knob. The fine adjustment knob is smaller in size. You should never, ever use the coarse adjustment knob under the high objective, you could scratch the microscope slide, cover slip, high objective lens, or in a worst case scenario break the high objective lens.
