Installing the Pushbutton Air Valve
Once the Power Unit and the Flex Tube are installed, you can install the Pushbutton Air Valve, which
requires the Zero Angle Bracket (which may already have been installed).
The Pushbutton Air Valve is used to lower the Runways. It can go on either side of the Power Unit,
whichever is easier to access for the Lift operator.
Once the pushbutton is in place, you need to connect it to both the Air Line (which is coming out of the
Flex Tube) and the customer-supplied air pressure.
An Air Supply (3 to 25 cfm at 50 to 150 psi) is required to disengage the Safety Locks when you want
to lower the Lift. Regulate the line to a maximum pressure of 150 psi; the air lines could burst or the
Safety Locks malfunction at pressure over 150 psi.
The following drawing shows the Zero Angle Bracket and where it connects.
The components involved include:
•
Zero Angle Bracket
. Attaches at the Mounting Bracket on the Power Post or to other available
holes on the Back Plate of the Power Unit. Holds the Pushbutton Air Valve, so be sure to orient the
Zero Angle Bracket so that the Pushbutton Air Valve can be easily reached by the Lift operator.
•
Pushbutton Air Valve
. Used to lower the Runways.
•
Air Line Compression Elbow Fitting
. Connects the Pushbutton Air Valve to the Air Line
coming out of the Flex Tube.
•
Straight Expander Fitting
. Connects the Pushbutton Air Valve to the customer-supplied air
pressure.
To install the Pushbutton Air Valve:
1.
Find the necessary components: Zero Angle Bracket, Pushbutton Air Valve, Air Line Compression
Elbow Fitting, and Straight Expander Fitting.
2.
Connect the Zero Angle Bracket at the desired location (if it has not already been connected).
It can attach to an available hole on the Back Plate of the Power Unit or to one of the Bolts that
connect the Power Unit to the Mounting Bracket on the Power Post.
The best location is one that is visible and easily reached by the Lift operator.
3.
Connect the Pushbutton Air Valve to the Zero Angle Bracket.
Use the two holes on the Pushbutton Air Valve on the side away from the actual pushbutton. If you
use the holes next to the pushbutton, the Zero Angle Bracket interferes with the pushbutton when
you try to use it.
