==Operating Instructions==
The air suspension is controlled by automatic valves that maintain a constant vehicle height by pressurizing or exhausting air in the springs as needed to support the load being carried.
The air suspension is controlled by automatic valves that maintain a constant vehicle height by pressurizing or exhausting air in the springs as needed to support the load being carried.
IMPORTANT NOTE --- Most trouble or failures do not put the suspension out of operation. Road repairs are not necessary for anything less than a major breakdown. Temporary steps can be taken to continue careful operation for many miles until such time it is convenient to make repairs. Safe air brake pressure of '''65 PSI''' is automatically maintained by a brake protection valve in the event of an air loss due to a failure in the suspension air system. Rubber bumpers inside the air springs carry the loaded vehicle, should all air springs go flat.

# Measure distance from floor to top of frame in the same area that Valve and Link Assembly are located. Adjust Valve by loosening adjustment lock nut and carefully move nylon block until proper height dimension is reached. Tighten Adjustment Lock Nut. ''NOTE:'' It will require from (2) to (6) seconds after moving nylon block before air starts to flow through Valve due to a built-in time delay.
