( 1 ) On Demand Engine Power "Enabled"
( 2 ) Two pump main relief (Boom UP).Note: A New specification is the performance that can be expected for a new machine. A Rebuild specification is the performance that can be expected after rebuilding the components of a system. Performance beyond the Service Limit is an indication of these problems: improper maintenance or adjustment, component wear and failure.Introduction
