DX41 Routine Laboratory Microscope

Safety notes

1. Carefully open the box, taking care not to damage any of the delicate accessories like the lenses.

2. Keep the instrument out of direct sunlight, high temperature or humidity, and dusty & dirty environments.

Make sure the stage is placed on a smooth, horizontal and even surface.

3. When moving the instrument, please use both hands to grip the two sides of the microscope's body.

4. If the bacterium solution or water splash onto the stage, objective or viewing tube, turn off the microscope

at the mains immediately and wipe the microscope using the soft cloth provided (preventing any damage to

the DX41).

5. When the DX41 is in use, the lamp housing and nearby parts will be very hot. Please ensure there is

enough room surrounding them to enable them to cool down.

6. Make sure the instrument is earthed, to avoid any electric shocks.

7. For your safety, make sure the main switch is off (“O”) before replacing the halogen lamp or the fuse. Turn

the power off, and perform the operation after the lamp bulb and the lamp house are completely cool.

8. Check the input voltage: make sure the input voltage which is marked on the back of the microscope is

consistent with the power supply voltage otherwise, it will cause serious damage to the instrument.

9. Please use the power cord supplied.

Maintenance

1. All the lenses have been thoroughly checked and adjusted - do not try and disassemble them yourself!

2. The nosepiece and coarse/fine focus unit have a compact and precise frame. Please don’t disassemble

them.

3. Keep the instrument clean by wiping dust regularly and avoid contaminating the optical elements.

4. Contamination on the prism, like finger prints and smears, can be gently wiped with a piece of soft cloth or

gauze which has been immersed in pure alcohol or xylene*. *(note that the alcohol and the xylene are

flammable, avoid using near direct heat).

5. Do not use an abrasive solvent to wipe the non-optical elements, use a soft detergent only.

6. If the microscope is splashed by any form of liquid, turn off the power immediately, and wipe up the

moisture.

7. Do not disassemble any part of the microscope. This will affect the function and the performance of the

microscope.

8. Place the instrument in a cool, dry position. After using the microscope, remember to cover it with dust

cover. Wait for the lamp housing to cool completely before covering.

Assembly

Assembly Diagram

The following diagram shows the assembly

sequence of the components.

The number in the figure shows the assembly steps.

Before assembling, make sure every component is

clean and be careful not to scratch any of the parts or

glass surfaces.

Keep the hexagon wrench

(supplied) in a safe place.

If you plan to change any of

the components in the
