INTRODUCTION
This manual provides you information necessary for the installation,
adjustment, inspection, and safe operation of SAF-HOLLAND
External Dock Lock (EDL) Automatic Reset Feature (ARF) for
Trailer Air-Ride Suspensions.
The SAF-HOLLAND EDL is designed and engineered to provide
trouble-free service. In the event of an inoperative EDL, such as a bent
rod assembly or a damaged cam bracket, the vehicle should be driven
CAUTIOUSLY at slow speed, to the nearest service facility for repair
or replacement.
This EDL/ARF uses air drawn from the truck/tractor air system to
operate the EDL actuator. The height control valve regulates the air
pressure required for varying loads. The ARF feature ensures the
flipper plate(s) will not be trapped down (engaged position) while the
trailer is in motion.
