3_Operation for oil immersion
Use the oil immersion as little as possible. The oil immersion will be conglutinated to the
stage and condenser and this will have bad effect the performance if there is too much oil
immersion. Please clean the redundant oil on the objective and condenser after finishing
the observation otherwise the image will be affected. Use the aether to clean the oil then
use the pure alcohol (ethanol or carbinol) to make entirely cleaning. Please repeat the clean
three or four times.

Please follow the instruction from manufactures when the aether or pure alcohol is used.
Keep them away from the fire or electronic spark
