D4-9 / D4-9X Four-Post Lifts 53 P/N 5900251 — Rev. A1— August 2021
Final Leveling
The following procedure describes how to fine tune how level your Lift is.
To perform final leveling on the Lift:
1. Raise your Lift to the first Safety Lock position.
2. Use a transit level or other leveling mechanism to evaluate how level the Posts and Runways are.
3. If you need to adjust a Runway, use the Top Nut and Stop Nut on the Top Cap of each Post to
make adjustments to the Ladder in that Post (which impacts the levelness of the Runway and
when the Safety Locks engage).
4. Raise the Lift to full height, listening as the Safety Locks engage.
If the Safety Locks are engaging at the same time, no further adjustments are necessary.
If the Safety Locks are not engaging at the same time, check the leveling, make necessary
adjustments, and then raise the Lift again and listen as the Safety Locks engage.
5. When you are satisfied the Lift is level, firmly secure the Nuts at the top of each Post.
