V. MAINTENANCE
1. Sweep the lens
Sweep the lens by lens tissue or soft fabric immersed with a
mixed liquid of alcohol/ether. Clean the 100x objective from oil
whenever you finish operating.
2. Clean the painted parts
The dust on the painted parts can be removed by gauze. For
the grease spots, the gauze immersed slightly with aviation
gasoline is recommended. Do not use organic solvents such
as alcohol, ether or other thinner etc. for cleaning the painted
parts or plastic components.
3. Avoid disassembling the microscope
Because of being a precise instrument, do not disassemble
the microscope casually. That may cause serious damage to
its performance.
4. Being not used
Cover the microscope with the dust cover and place it there,
where it is dry and mouldless. We suggest the storage of all
objectives and eyepieces in a closed container with drying
agent.
