NOTE: It may be necessary to use jack stands to support the first table
section if fewer than four isolators are located under the section.
5. Position the second table section on three jack stands mounted on dollies.
Adjust the position of the table so that it is at the same height as, and
adjacent to, the first table section.
6. Align the two table sections using a straight edge. Carefully roll the
second table section toward the first so that the alignment dowel pins
engage in their mating holes. Be sure the bolts are aligned with their
corresponding holes.
7. Draw the two table sections together approximately
1
⁄
8
inch (5mm) using
the two outermost top bolts.
CAUTION
Do not force the bolts. The second table section should be
easily pulled up to the first. Figure 2.13 shows correct bolt head
position during assembly.
Do not cause the first table section to shift sideways on its
isolators. Doing so could damage the isolators.
8. Tighten all of the bolts until they are finger-tight or until they just begin
to move the table sections together. Do not force or over-tighten the
bolts.
9. Repeat steps G and H until the two table sections are completely drawn
together.
10. When all bolts are snug, apply a final torque of 60 pound-feet (80 N-M)
to all bolts using the sequence shown in Figure 13.
11. Jack up the assembled table as required to install the remaining isolators
and leveling valves. Install the isolators and valves as described in
Section 2.1.
12. Remove the jack stands and level the table as described in
Section 2.3.
13. Install the air lines and float the table as described in Section 2.3.
