D4-9 / D4-9X Four-Post Lifts 19 P/N 5900251 — Rev. A— October 2020
Moving the Posts into Position
The four Posts are not the same; two have their Safety Lock Holes on the left, the other two have their
Safety Lock Holes on the right (when you are looking at them straight on).
When you put the Posts into position, make sure the Safety Lock holes are on the
outside . This
orientation is
required so that the Safety Locks in the Crosstubes line up with the Safety Lock Holes
in the Posts.
The Power Post must be a “right” Post, but you can use either “right” Post as the Power Post.
⚠ DANGER The Posts are heavy and awkward; be very careful when handling them. If they fall
on a person, they will cause injury.
To move the Posts into position:
1. Using a Forklift or Shop Crane, move the four Posts, one at a time, to the inside corners of the
Chalk Line Guides.
Important: Position the Power Post at one of its two allowed locations, then move the other three
Posts into appropriate locations.
Not all components shown. Not necessarily to scale.
2. Stand up each Post. Have at least two people work together to stand up a Post.
⚠ CAUTION Use caution when walking around the Posts. They are not anchored down at this
point, so it is possible to knock them over, which could cause injury.
3. When all four Posts are standing up, check all four to make sure the Safety Lock Holes are on the
outside of the Lift.
4. Use a Transit Level to estimate the Shim requirements, if anchoring the Lift.
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 use Shims and/or Anchor Bolts to Shim more than half an inch. You can order 2 inch Shim
plates for extreme cases.
5. Do
not anchor the Posts at this point, even if you plan on anchoring them (which is optional).
