8. PRECAUTIONS IN DISASSEMBLY AND REASSEMBLY
The disassembly and reassembly procedures for the Model C 6SE and C 7SE are essentially the same. The [ ]
numbers in descriptions below correspond to the item numbers in the parts list and exploded assembly diagram
for the Model C 6SE, and the < > numbers for the Model C 7SE. During disassembly and reassembly, and at all
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.
