Maintenance:
Page 5
If the microscope becomes wet during use, power off the microscope and dry the microscope
thoroughly.
Wipe lenses gently with a soft tissue. Carefully remove excess oil from the 100x immersion oil lens.
Wipe off fingerprints from lens surfaces with lens paper using a small amount of microscope cleaning
solution or a 3:7 mixture of alcohol and ether or dimethylbenzene. (Alcohol and ether are flammable,
do not place these chemicals near fire and clean in a ventilated area.)
When cleaning other surfaces of the microscope use water only. A basic detergent can be used to
clean the surface if necessary, but ensure that all the detergent is removed from the frame with a
clean, damp cloth prior to drying the surface.
Do not disassemble the microscope.
After use, cover the microscope with a dust cover and power off the light.
