Use and Care Manual

HD-9 Series Four-Post Lifts 41 P/N 5900123 — Rev. M1 — March 2020
To install the Air Lines:
1. Find the roll of supplied ¼ inch, black, polyethylene Tubing and three Air Line Tee Connectors.
2. Measure the distances for each of the seven (7) Tubing pieces you will need (see the drawing on
the previous page) for the Air Lines.
3. Cut seven pieces of Tubing to the measured lengths from the roll of Tubing.
4. Connect the various pieces of Tubing to the Air Line Tee Connectors on the Lift, as shown in the
drawing on the previous page for the locations of the Tubing pieces.
Make sure to position the three Air Line Tee Connectors as shown in the
drawing
.
Also, route the long Tubing piece that goes under the Powerside Runway through the Steel Tubes;
they keep Air Lines are out of the way of where the Cables will be routed.
⚠ WARNING Make sure to route the Tubing pieces on the outside ends of the Front and Rear
Crosstubes through the Steel Tubes on the ends of the Crosstubes. This keeps the
Tubing and the Tee Connectors from being disturbed as you use the Lift. This is
important, because if the Air Lines are disturbed, the Safety Locks on the Lift may
not work correctly. If you notice that Tubing has become disconnected from an Air
Line Tee Connector, take the Lift out of service and get the Air Lines fixed.
Refer to Working with Compression Fittings and Tubing for more information about
connecting the Tubing to the Air Line Tee Connectors.
5. Leave the Power Unit end of the Air Line hanging out of the Flex Tube opening for now.
It will be connected to a Tee Fitting and the Pushbutton Air Valve later.
