1. The following sections describe the disassembly and assembly of units.

For correctly repairing these components, a wide experience in assembly and adjustment of medical equip-
ment is required. Only suitably qualified persons should carry out the following work.

2. The special tools for repair are as follows:

•

White whetstone for slit 

•

Slit holder tool 

If these tools are required, order them from TOPCON.
