Before allowing vehicle to leave always return the dock
leveler to its dock level (stored) position with the dock
level support legs supported by the front dock level
supports. Failure to do so may leave the dock leveler
in a position below the level of the dock floor. This
condition may result in unexpected drop of personnel
or material handling equipment and result in death or
serious injury.
