RBJ Series of Rolling Bridge Jacks 18 P/N 5900004 — June 2018 — Rev. C2
Setting Up the Air-Operated Hydraulic Pump
Your Rolling Bridge Jack comes with an Air-Operated Hydraulic Pump, which provides air pressure so
that you can raise and lower the Jack. It is your responsibility to supply air pressure to the pump.
Air pressure should be set to 20 cubic feet per minute (.57 cubic meters per minute) and 100 psi
(7 bar; bar is a metric unit of pressure). Normal air pressure is 100 psi (6.9 bar); do not exceed 125 psi
at any point, you can damage the Air-Operated Hydraulic Pump.
⚠ WARNING Before performing installation or maintenance, release the pressure currently in the
system, then disconnect the pump from its air pressure at the Air Intake Valve.
To set up your Air-Operated Hydraulic Pump:
1. Remove the thread protector from the Air Intake Valve on the pump.
2. Install a threaded fitting (not supplied) that is compatible with your air pressure supply.
3. Connect your air pressure supply to the threaded fitting you just installed on the pump.
⚠ CAUTION An appropriate air line regulator, water separator, and lubricator must be installed
on the air pressure supply line.
Failure to install these items could lead to
damage and voids the warranty on pneumatic components.
4. The Vented Fill Cap is tightened for shipment; loosen it approximately one turn for normal use.
