One thing that can happen if you use the coarse adjustment while the oil immersion objective is in place is that the slide will end up breaking. It is better to use the fine adjustment.

What are the 2 knobs on a microscope called?
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.
What part of the microscope should you used to focus the image when using high power objective lens?
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.
Which objective should the coarse focus knob be used?
The coarse adjustment knob is only used with the low-power objective lens (usually 4x) because all the other ones are too long and the coarse adjustment knob may bring the slide up too qucikly, therefore it might break the slide or crush the specimen being observed. When using the medium (10x) and high (40x) power objective lens, it is best to use the fine adjustment knob to focus on the details instead.

Why would you never use the coarse adjustment knob on high power?
The coarse adjustment knob may move the lens too far too fast and the slide may crack and/or the object be squashed. Using the fine adjustment lens will bring the object into focus much more accurately. In addition, the coarse adjustment knob adjusts in too great a quantity. The fine is less responsive so its easier to adjust at high magnification.

The course adjustment moves the stage of the microscope further/closer away from the objective lens (it is used for general focusing), and the fine adjustment moves the objective lens very small distances for finer focusing.
