2. Maintenance

1. All the lenses have been well checked and adjusted. It is forbidden to disassemble them yourself.

2. The nosepiece and coarse/fine focus unit have a compact and precise frame, please don’t

disassemble them as possible as you can.

3. Keep the instrument clean, wipe dust regularly, and be attention to avoid contaminating the

optical elements especially.

4. The contaminations on the prism, as finger mark and oil, could be gently wiped with a piece of soft

cloth or tissue paper, gauze which has been immersed in pure alcohol or xylene. (note that the

alcohol and the xylene are all burned easily, do not let them near the fire, and use them in a

drafty room as possible as you can.)
