Most tandem roller trouble that stalls a mat starts small: a dry water tank, a clogged fuel pre-cleaner, a skipped 250-hour service, and catching those early is exactly what this 116-page factory operator manual (OEM 008 111 81) is for. Written for four BW-4 series machines, the Bomag BW 161 AD-4, BW 202 AD-4, BW 161 ADH-4 and BW 203 AD-4 operator manual PDF schedules every check on its maintenance chart, from the 10-hour walk-around to the 1500-hour service, and maintenance work fills roughly a third of the book. Operating sections walk you through starting on jump wires, crabwalk travel, the pressure sprinkling system and edge cutter, plus towing and frost protection for the water lines. Fill the crankcase with 10 litres of oil, filter included, and set intake valve clearance to 0.3 mm. Nobody hauls a paper binder up onto a roller. Bookmarked and text-searchable, your copy rides wherever the machine does.
