P/N 5900246 — Rev. B — July 2021
To install the Air Lines :
1. Find the roll of supplied ¼ inch, black, polyethylene Tubing and three Air Line Tee Fittings.
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 Tee Fittings 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 Fittings as shown in the previous
drawing .
⚠
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 Fittings 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 Fitting, 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 Fittings.
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.
