Detailed explanation-1: -COARSE ADJUSTMENT KNOB-A rapid control which allows for quick focusing by moving the objective lens or stage up and down. It is used for initial focusing.
Detailed explanation-2: -The coarse adjustment knob is used ONLY with the low power (4X, 10X) objectives. When focusing under the 40X or 100X objective, ONLY use the fine adjustment, never the coarse adjustment.
Detailed explanation-3: -Coarse and fine adjustment The coarse adjustment knob should only be used with the lowest power objective lens. Once it is in focus, you will only need to use the fine focus. Using the coarse focus with higher lenses may result in crashing the lens into the slide.
Detailed explanation-4: -CAUTION: NEVER, EVER, use the coarse adjustment knob with the high power objective. This could break the lens.
