In the majority of applications the dock attendant positions the dock leveler on the truck. When the truck is loaded the dock attendant typically operates and returns the dock leveler to the stored closed position. If there is no dock attendant and the truck departs with the dock leveler in position the dock leveler lowers and the lip slowly retracts. If equipped with an optional auto return when the lip reaches the fully retracted position a limit switch is activated. This starts the lift motor. The deck raises and the lip clears the lip keepers. The timer shuts off the motor and the deck lowers to the properly stored closed position.
