Answer:
compound microscope should be treated as a VERY, VERY, VERY fragile piece of equipment.
1. Adjustments should be made gently and with finesse.
2. ALWAYS use both hands when picking the microscope up and moving it from one place to another.
3. When focusing on a slide, ALWAYS start with either the 4X or 10X objective. Once you have the object in focus, then switch to the next higher power objective. Re-focus on the image and then switch to the next highest power. Etc. NEVER advance more than one objective before focusing.
4. Use ONLY the fine focus control when

The coarse adjustment knob located on the arm of the microscope moves the stage up and down to bring the specimen into focus.
The optics of a microscope's lenses change the orientation of the image that the user sees. Similarly, if the slide is moved left while looking through the microscope, it will appear to move right, and if moved down, it will seem to move up.
Look at the objective lens and the stage from the side and turn the focus knob so the stage moves upward. Move it up as far as it will go without letting the objective touch the coverslip. You might need to readjust the sample into focus and/or readjust the condenser and light intensity.
A microscope is an instrument that magnifies an object. The optics of a microscope’s lenses change the orientation of the image that the user sees. A specimen that is right-side up and facing right on the microscope slide will appear upside-down and facing left when viewed through a microscope, and vice versa.
