Never use this knob on high power.
A
Fine Adjustment
B
Large Focus
C
Coarse Adjustment
D
Small Focus
Explanation: 

Detailed explanation-1: -CAUTION: NEVER, EVER, use the coarse adjustment knob with the high power objective. This could break the lens. Multiply the power of the ocular lens, by the power of the objective lens.

Detailed explanation-2: -Since the coarse-adjustment knob is used to find the specimen, combining this with the high-power objective lens could cause you to move the stage too quickly and break the slide under the lens.

Detailed explanation-3: -If a student uses the coarse focus knob when the 10X (yellow) and 40X (blue) objectives are in place the student will definitely lose the view of the object being served and may damage the lens or sample.

Detailed explanation-4: -If you focus the high power objectives with the coarse focus knob, then you risk slamming the objective into the slide, risking the damage of both. Some high power objectives are spring-loaded, with a front-part that retracts when touched by the slide. This is a protective mechanism.
