3. Vacuum each hole clean.
BendPak recommends using a vacuum to get the hole very clean. You can also use a wire brush,
hand pump, or compressed air; just
make sure to thoroughly clean each hole .
Do
not ream the hole. Do not make the hole any wider than the drill bit made it.
Important: The holding strength of an Anchor Bolt is partly based on the how cleanly the
Expansion Sleeve presses against the Concrete. If the hole is dirty, the Expansion
Sleeve does not press as cleanly. If the hole is too wide, the Expansion Sleeve does
not press with as much force. Both result in less holding strength.
4. Plumb each Post; install any needed Shims.
Use a Transit Level to estimate the Shim requirements: use a target to find the difference in height
between the Posts. The difference is the estimated amount of Shim thickness you will need.
Do not shim a Post more than half an inch using the provided Shims. A maximum of 2 inches is
possible by ordering optional Shim Plates. Contact BendPak at [phone], extension 191
to order. Please have the model and serial number of your Lift available.
Take your time while plumbing and shimming the Posts;
your goal is to make the Lift as
level as possible
.
5. Make sure the Washer and Nut are in place,
with the top of the Nut flush with the top of
the Anchor Bolt
, then insert the Anchor Bolt into the hole.
