and even affect its normal use in surveying work.

1. Keep the instrument in the dry, clean and well-ventilated room (the temperature shouldn't be below 25°C and humidity
below 70%).
2. Place the instrument on its place in the case. When you take it out, hold with one hand the tribrach and with
another- alidade. Try not to touch the telescope.
3. When you focus on the target use horizontal and vertical micrometer screws, try to rotate them clockwise.
4. Doing this, rotate the instrument holding the alidade. Do not use for this purpose the telescope.
5. In the hot weather to protect the instrument from the sunlight, use the umbrella. Use the umbrella or the rain cover to protect
the instrument from the rain.
6. After using the instrument, remove all dust and dirt from its surface, and then put the instrument into a clean, dry case.
