HD-14T Four Post Lift 20 P/N 5900037 — Rev. F — February 2022
Creating Chalk Line Guides
Create the Chalk Line Guides so that the outside edges of all four Posts fit into the four corners
created by the Chalk Line Guides.
See Specifications to determine the Overall Width and Outside Length values for your Lift.
Note: Do
not
use the
Overall
Length value; this includes the Ramps, which are not taken into
consideration for creating Chalk Line Guides.
To create Chalk Line Guides:
1. Create the Front and Rear Chalk Lines; make the Front and Rear Chalk Line longer than the
Overall Width setting.
The Front and Rear Chalk Lines
must
also be parallel to each other; measure to verify that they
are parallel.
2. Create the two Side Chalk Lines at 90° angles to the Front Chalk Line and parallel to each
other; make the Side Chalk Lines longer than the Outside Length setting
3. Before moving the Posts into position, measure
diagonally
to make sure the two diagonal
measurements are the same. This ensures your layout is correct.
Do not forget to check the diagonals.
4. When you move the Posts into position, put the corners of the Base Plates inside the corners
created by the four Chalk Lines.
