4. Apply power to the table. While pressing the FLOAT foot pedal (or FLOAT
push button switch), push in the two float top longitudinal electromagnets so
locks are in "released" position (see Figure 8). This will provide sufficient
clearance to slide the table top past the magnets, and will avoid magnet
bracket adjustment required if the magnet brackets are loosened for table top
installation. If table top cannot be installed in this way, the two (2) hex head
bolts securing each Longitudinal Magnet Bracket must be loosened to permit
tabletop installation.
5. Slide the Table to Assembly onto the bearing assemblies from the right-hand
end of the table (as viewed from front of table).
6. Verify tabletop frame is square as follows:
a. At one end of the table, measure the distance between the inside
edges of tabletop rails as shown in Figure 7. The distance should be
27"±1/16". If not, loosen two (2) socket head cap screws securing
End Tabletop Support to Tabletop Rail (see Figure 7). Adjust set
screws until required distance is attained, then re-tighten socket
head cap screws.
b. Repeat the above measurement at the opposite end of the table and,
if necessary, adjust width of tabletop as in previous step. However,
ensure the difference between the two widths (i.e., step 10a width
minus step 10b width) does not exceed 1/32" as this may adversely
affect tabletop motion.
