8. PRECAUTIONS IN DISASSEMBLY AND REASSEMBLY
The disassembly and reassembly procedures for the Models C 9U2 and C 9BU2 are essentially the same. The
[Bold]
numbers in the descriptions below correspond to the item numbers in the parts list and exploded assembly
diagram for the Model C 9U2. During disassembly and reassembly, and at all other times as well, sufficient care
must be exercised in handling to ensure that there is no deviation in the flatness of the bottom surface of the base
and in its perpendicularity with relation to the saw blade.
