Detailed explanation-1: -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-2: -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-3: -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-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.
Detailed explanation-5: -Never use the coarse adjustment knob when focusing with the high-power or oil immersion objectives in place as this can damage the objective or the slide.
