7. Column Anchoring:
A. Keep columns square to center line of lift. Check
lift location in the bay. Check dimensions side-to-
side, front-to-rear, and diagonally. Diagonals must be equal
to within 1/4", Fig. 11.
B. Move column towards yoke until the sliders contact the back
of column, center yoke in column, Fig. 10.

C. Place shims (estimated in Step 3) under each column. Drill
four 5/8" diameter holes through concrete floor using base
holes as guide. See Fig. 12a and 12b for hole depth, hole
spacing, and edge distance requirements. Repeat for other
columns.
D. Insert base anchors, Fig.'s 12b and 13.
E. Tighten nuts, Fig. 12b. Check columns for plumb and level.
Re-shim if necessary. Torque anchor bolts to 60 ft. lbs., Fig.
12b.
F. If anchor bolts do not hold when torqued to required amount,
concrete must be replaced. Saw cut and remove 24" x
24" square area under each column base. Repour with
reinforced 3000# minimum concrete to depth of 6", keying
new concrete under existing floor.
