4. If anchors do not tighten to 85 ft-lbs. installation torque, replace the concrete under each column base
with a 4’ x 4’ x 6” thick 3,000 PSI minimum concrete pad keyed under and flush with the top of existing
floor. Allow concrete to cure before installing lifts and anchors (typically 2 to 3 weeks).
ANCHORING TIP INSTRUCTIONS
Anchors must be at least 6” from the edge of the slab or any seam.
1. Use a concrete hammer drill with a carbide tip, solid drill bit the same diameter as the anchor, ¾”. (.775 to
.787 inches diameter). Do not use excessively worn bits or bits which have been incorrectly sharpened.
2. Keep the drill in a perpendicular line while drilling.
3. Let the drill do the work. Do not apply excessive pressure. Lift the drill up and down occasionally to re
move residue to reduce binding.
4. Drill the hole to depth equal to the length of anchor. Note: Drilling thru concrete (recommended) will al
low the anchor to be driven thru the bottom of foundation if the threads are damaged or if the lift
will need to be relocated.
5. For better holding power blow dust from the hole.
6. Place a flat washer and hex nut over threaded end of anchor, leaving approximately ½ inch of thread
exposed carefully tap anchor. Do not damage threads. Tap anchor into the concrete until nut and
flat washer are against base plate. Do not use an impact wrench to tighten! Tighten the
nut, two or three turns on average concrete (28-day cure). If the concrete is very hard only one or
two turns may be required. Check each anchor bolt with torque wrench set to 85 foot pounds.
CAUTION!
