Factory service manual for the BOMAG BW 190 AD-4 AM and BW 203 AD-4 AM tandem vibratory rollers with Asphalt Manager. This is the workshop book, not the operator's leaflet: pressure tests for the travel and vibration circuits with nominal values (travel pump 440 bar high pressure limitation, charge pressure 25 +3/-1 bar), angle sensor adjustment for the travel control lever, flushing and bleeding procedures after a component change, and removal/installation of drums and exciter units. Covers the Deutz BF4M 2012 C engine (98 kW at 2300 rpm), ESX control fault codes, the BAM and A03/A68/A71 electronics modules, wiring and hydraulic diagrams, air conditioning, frame weld repair, and a full Asphalt Manager service training section.
