4) The anchor bolts must be installed at least 8”
from any crack, edge, or expansion joint.
5) Use a concrete hammer drill with a 3/4 inch
carbide bit. Tip diameter should conform to
ANSI Standard B94.12-1977 (.775 to .787).
Do not use excessively worn bits or bits
which have been incorrectly sharpened. A
core bit may be necessary if an obstruction is
encountered.
Never substitute with shorter
anchor.
6) Recheck “Inside of Columns” dimension,
Fig. 1
. Drill the anchor holes using the base
plate as a template. Drill through the floor if
possible or to a depth of 5 inches minimum.
7) Vacuum dust from the hole for proper holding
power.
8) Shim both columns to plumb using the shims
provided as shown in
Fig. 2
. DO NOT shim
more than 1/2" at any given point. Use a level
no less than 24” in length to plumb columns.
9) Assemble washer and nut to anchor with nut
just below impact section of bolt. Drive
anchor into hole until nut and washer contact
base.
