5.
Level the baseplate both lengthwise and across by adding or removing shims or moving the wedg-
es.
These are the leveling tolerances:
•
A maximum difference of 3.2 mm | 0.125 in. lengthwise
•
A maximum difference of 1.5 mm | 0.059 in. across
You can use the baseplate-leveling worksheet when you take the readings.

Hand-tighten the nuts for the foundation.
4.2.3 Install the baseplate using jackscrews
Tools required:
•
Anti-seize compound
•
Jackscrews
•
Bar stock
•
Two machinist's levels
•
Baseplate-leveling worksheet
This procedure is applicable to the feature-fabricated steel baseplate and the advantage base baseplate.
1.
Apply an anti-seize compound on the jackscrews.
The compound makes it easier to remove the screws after you grout.
2.
Lower the baseplate carefully onto the foundation bolts and perform these steps:
a) Cut the plates from the bar stock and chamfer the edges of the plates in order to reduce stress
concentrations.
b) Put the plates between the jackscrews and the foundation surface.
c)
Use the four jackscrews in the corners in order to raise the baseplate above the foundation.
Make sure that the distance between the baseplate and the foundation surface is between 19 mm |
0.75 in. and 38 mm | 1.50 in.
d) Make sure that the center jackscrews do not touch the foundation surface yet.
