HD-14T Four Post Lift 43 P/N 5900037 — Rev. F — February 2022
Installing the Air Line
The Air Lines use air pressure to disengage the Safety Locks in each Post so that you can lower the
Runways. You will need more of the ¼ inch, black, polyethylene Tubing that came with the Lift and
three Air Line Tee Connectors to install the Air Lines.
An Air Supply (3 to 25 cfm at 50 — 150 psi) is required to disengage the Safety Locks.
⚠ CAUTION
Do not let the Air Supply exceed 150 psi
; the Air Lines could burst or the
Safety Locks malfunction.
The Air Line Elbow Connectors on the Air Cylinders come installed from the factory.
⚠ CAUTION Do not confuse the Air Lines with the Return Line. They use the same Tubing and
similar-looking connectors, but they are used for completely different things; the
two systems cannot be connected to each other.
The Compression Elbow Fittings on the Crosstube Gussets come installed from the factory.
Air Lines shown outside Steel Tubes for clarity. Drawing not to scale. Some components not shown.
