GrandPrix (GP-7 Series) Two-Post Lifts 21 P/N 5900209 — August 2018 — Rev. C2
Once past the hole in the Base Plate, the Anchor Bolt eventually stops going down into the hole as
the Expansion Sleeve contacts the sides of the hole; this is normal.
7. Hammer or mallet the Wedge Anchor the rest of the way down into the hole.
Stop when the Washer is snug against the Base Plate.
8. Plumb each post; install any needed Shims or the optional Adapter Trays (which let you stack the
provided adapters conveniently near the Lift Arms).
Tip If you are going to torque the Anchor Bolts later so that installing the Top Trough and
doing final leveling is a little easier, skip the next step. Instead, make sure the Anchor
Bolts are securely in position; you do not want the posts moving during the rest of the
installation procedure.
9. Wrench each Nut
clockwise
to the recommended installation torque, 110 – 150 foot pounds,
using a Torque Wrench.
Important: Do
not
use an impact wrench to torque the Anchor Bolts.
Wrenching the Nut forces the Wedge up, forcing out the Expansion Sleeve and pressing it tightly
against the Concrete.
