To start, determine what type of binoculars belongs to your model. There are two types of these devices: classic compact Porro and Roof. Note that they have different structure. Based on these data, read the relevant literature or consult with a specialist. The easiest way to learn about the sequence of disassembly of the binoculars is to read the instructions.
Many modern binoculars are filled with nitrogen inside. This is done to avoid fogging of the prisms and lenses due to temperature changes. That is, when the opening of the case you can release nitrogen. So once again weigh the "pros" and "cons" – whether disassembly is required?
Prepare the workspace. It would be better if the table surface is closed with a soft cloth. Start to disassemble the binoculars. Unscrew the tiny screws on the body, they can be covered and therefore completely invisible.
Disconnect the tube with lenses and remove closing cap. Gently loosen the prism from the clips. In the process of dismantling details memorize the structure of the binoculars. If possible – keep before the eyes of the user manual with the scheme. When detaching the parts, wipe them with a cloth dampened with cleaning fluid. However, the lenses and prisms before that process the air from the cans of "Dust Off" to blow away the dust. If from the beginning to use cloth, dust will leave microscopic scratches.
In the same sequence collect the binoculars back. Of course, all this is General advice. Binoculars very much, and each model requires an individual approach to disassembly. And if you are not confident in their abilities, it is best to take the device in the optical workshop.
