Caution in Handling and Maintenance

•Avoid touching lens surfaces with the fingers or with any rough material . For dusting, use a feather or a soft lens brush and then a washed - out soft cotton cloth only to wipe off finger marks or grease, wet the cloth with xylor, but never with alcohol or ether.

The microscope body surfaces should be dusted in the same way and may slightly be oiled,

•Tightness of the coarse focusing knobs should be adjusted, in this type (L-Ke) of microscope, by means of the adjusting ring, not by twisting the knobs.

•Dismantling of the internal optical parts and the microscope body should not be attempted, because it may interfere with the performance of the instrument . It can be accomplished only by an expert or the original manufacturer .

•Do not apply any grease of not specified type to the sliding surfaces of the coarse focusing adjustment and of the floating stage. If necessary, ask for your dealer or the manufacturer .

•The microscope is to be used at a dust-free place. Avoid any forcible manipulation of the moving parts. At all times the instrument is to be handled carefully e.g. for carrying the microscope, hold its base with one hand and its arm with the other.

•When not in use, it should be covered with the vinyl cover or kept in the wooden cabinet which is available on order. Store it at a dry place. It is recommended to keep the objectives and eyepieces in a desiccator.
