30 degrees (25 degrees forward and 5 degrees rearward of the vertical). When the carriage is
fully elevated, the height from the ground to the top of the forks, when fully loaded, shall be
approximately 13 feet. The time required for the complete dumping cycle from travel position
and return to travel position, shall be not more than 2 minutes.
