The device includes a controller which compares programmed store and retrieve heights for various shelves in a warehouse with the current height of the fork. A display visible to the operator includes a first display device which indicates the fork is adjacent a particular shelf and is within a predetermined range encompassing the store and retrieve heights of that shelf. A second display device indicates when the fork is at or within a predetermined range of the store or retrieve height for the shelf.
