HD-7P / HD-7W Four-Post Lifts
44
P/N 5900041 — Rev. M — July 2019
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 to 150 psi) is required to disengage the Safety Locks. Regulate the
line to a maximum pressure of 150 psi.
⚠
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.
Important
:
Do not confuse the Air Lines with the Return Line. They use the same Tubing and
fittings, but they are used for completely different things; the two systems
must not
be connected to each other.
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).
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.
Refer to 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 make sure to route the long Tubing piece that goes under the Powerside Runway through the
Retaining Rings. You need to make sure the Air Lines stay out of the way of the Lifting Cables.
⚠
CAUTION
Make sure to route the Tubing pieces on the
outside
of the Front and Rear
Crosstubes
through the Steel Tubes
on 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
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 for now.
It will be connected to the Pushbutton Air Valve later in the installation process.
