8. PRECAUTIONS IN DISASSEMBLY AND REASSEMBLY
The procedures for disassembly and reassembly and certain precautions are described below.
The [Bold] numbers in the descriptions below correspond to the item numbers in the parts list for all the models.
In disassembly or reassembly and also in other work, the Base Ass'y [52] should be carefully handled to prevent
the loss of the accuracy of each part, such as the flatness of the bottom surface.

diameter of 42 mm to 43 mm (approx. 1-23/32"), and
