Machine Anchoring
1. Anchors must be installed at least 5-11/16” from
any edge or seam in concrete.
2. The concrete must be at least 4-1/4” thick with a
compressive strength of 3000psi.
3. Use a hammer drill with a carbide tip, ¾” diameter
solid drill bit. The bit tip diameter should be to ANSI
Standard B95.12-1977 (.775” to .787”).
4. Keep drill perpendicular to the floor while drilling.
Let drill do the work. Drill the hole completely
through the slab. Clean dust from hole using a
vacuum. (See Figure 30)
5. Assemble the washers and nuts onto the anchor
bolts. Thread the nuts onto the anchor bolts where
the top of the nuts are just above the top of the
bolts, as shown.
6. Using a hammer, carefully tap the anchor bolts into
the concrete until the washer rests against the base
plate.(See Figure 31)
7. If more than 2” of shimming is required, do not use
the anchors and shims provided with the lift. Use
longer anchors and fabricate larger shims from
steel flat.
8. Once the machine is level, tighten the anchor bolts
to 150 ft-lbs. Do not use an impact wrench on
anchor bolts. (See Figure 32)
