INTRODUCTION
Component Identification

E — Hinge Area

The HED Edge-of-Dock leveler uses hydraulic pressure
and single push-button operation for ease of use.
Platform (B) is raised by pushing and holding the
RAISE button (J). This activates an electric motor (D)
which, in turn, drives a hydraulic pump. The hydraulic
pump forces oil into the platform cylinder (G), causing
the platform to rise. Hold (J) until lip fully extends.
Releasing the raise button will allow the platform to
float down to the bed of the truck trailer bed. The lip
will stay extended until the platform reaches the full
below dock position.
Pressing the raise button will return the platform and
lip to the stored position.
