Focusing arm
Focusing arm located on the stand allows the stage vertical movement. Handles are lined up at the both sides of the stand. The total focusing value is at least 15 mm.

Stage
The stage is fixed on the bracket secured on the focusing arm block. Specimen holder is located on the stage surface. Diaphragm disk is attached to the lower part of the stage. A stopping screw limits the movement of the stage bracket which eliminates the possible contact between the objective and the specimen.

Revolving head
Revolving head holds the objectives; to replace an objective, rotate the ring until it reaches the fixed position.

• The microscope should be kept clean and protected from damages. When it is not in use, cover the microscope with a special case.
• To maintain the microscope, regularly wipe dust off it, then clean it with a soft cloth slightly moistened with acid-free vaseline, and afterwards wipe it with a dry soft clean tissue.
• Metallic parts should be kept clean. Special attention should be paid to maintaining the optics (especially objectives and eyepieces) cleanliness.
• Never touch optic surfaces with your fingers.

In case if dust soiled the objective lens deep in the casing, carefully wipe the lens with a clean Q-tip slightly moistened with ether or spirits mixture. If you noticed dust inside the objective or a film on the inside of the lenses, the objective should be sent for repairs.
