Maintenance

1. Before using the prism, clean oil stain on the working surface of the prism with aviation washing gasoline, and then wipe it with a clean thick cloth or chamois.

2. In the process of using prisms, sweat gloves should be worn and handled with care to avoid hand contact with the working surface.

3. It is forbidden to use organic solvents such as alcohol to clean prism, because they will absorb moisture in the air and corrode the working surface of the prism.

4. Prisms should be used in a dry and clean environment.

5. After using the prism, it should be cleaned and wiped with aviation washing gasoline in time. It should be put into the dryer or the oil seal and stored in a dry place for proper storage. Do not collide, scratch or rust.

6. During transportation, the prism must be protected from bruise, rain, corrosive articles and harmful gases.
