ANCHORING LIFT
Drill hole using 3/4" carbide tipped
masonry drill bit per ANSI standard
B94.12.1977.
Clean Hole.
Run nut down just below impact
section of bolt. Drive anchor into
hole until nut &
washer contact base.
Tighten nut with Torque Wrench to
150 ft-lbs (203 N-m)

ANCHOR LOCATIONS
A Holes not used
B Drill (2) holes for 3/4" anchors through top, install
after raising.
C Drill (6) holes and install 3/4" anchors.
3. Anchoring:
A. The anchor bolts must be installed at least 5-11/16” (145mm)
from any edge or seam in the concrete
B. Concrete shall have a compression strength of at least 3,000
PSI (20N/mm
2
) and a minimum thickness of 4-1/4” (108mm)
in order to achieve a minimum anchor embedment of 3-1/4”
(83mm). When using the standard supplied 3/4” x 5-1/2” lg.
anchors, if the top of the anchor exceeds 2-1/4” above the floor
grade, you DO NOT have enough embedment.
C. Drill (8) 3/4” dia. holes in concrete floor using holes in base
plate as a guide, see Fig. 3 & 4.
Note: DO NOT install anchors in holes marked "B" until AFTER lift
is raised, see Fig. 4.
CAUTION
DO NOT install on asphalt or other similar
unstable surfaces.
D. Tighten the anchor bolts to 150 ft-lbs (203 N-m). Do not use an
impact wrench on anchor bolts.
If after tightening the anchor supplied with the lift extends
more than 2-1/4” (57mm) above the floor the anchor does not
have enough embedment.
IMPORTANT
If an anchor will not reach the appropriate
torque level or does not have enough embedment or adequate
spacing cannot be achieved, replace the concrete under the
lift with an 7’ wide x 9’ deep x 6” thick pad (2m x 2.7m x 152mm)
of 3,000 psi (20N/mm²) concrete keyed under the existing floor.
Let the concrete cure before reinstalling the lift.
IMPORTANT
The frame must not be twisted, bent or
otherwise misaligned by unlevel floors or improper anchoring.
Misalignment will cause damage to the lift. Maximum out-of-
level at anchors is: 1/4" (6mm) side to side; 1/2" (13mm) front to
rear. If floor is crowned more than 1/4" (6mm) between front to
rear anchors, shim at anchors. Top structure to be parallel to
bases within 1/4" (6mm). Use shim kit FJ2426, or use grout to
level the floor.
