Introduction
This manual provides the necessary information for the care,
maintenance, inspection, and safe operation of the SAF-HOLLAND
Neway
®
ADZ Series Air Suspension. The Neway
Suspension is designed and engineered to provide trouble-
free service. In the event of minor breakdown, such as a loss
of air in the air springs, there are safety features designed
into the suspension that will allow the vehicle to be driven
CAUTIOUSLY at a slow speed, to the nearest service facility.
This suspension uses air delivered from the truck/tractor
air system to pressurize the air springs and is controlled by
either one (1) or two (2) height control valves. The height
control valve regulates the air pressure required for varying
loads and maintains the design ride height.
The Neway
ADZ Series Suspensions are designed to be
®
compatible with disc brake systems.
