From daily inspections through cold starts, sprinkler operation, towing and transport, this 98-page Bomag BW 120 AD-4 operator manual PDF (OEM 008 114 81) walks the full working routine of four rollers in the BW 100/120 line: two AD-4 tandem vibratory machines and two AC-4 combination models. Maintenance takes up more than a third of the book, running the whole service chart from checking the water separator to changing the hydraulic oil and bleeding the fuel system after a filter swap. Indicators and controls get their own illustrated section, so you know what every lamp on the dash means before it costs you a shift. Fill the engine with 6.5 liters of oil, the hydraulic tank with 28, and keep cleaning air under 5 bar at the combustion air filter. Small crew, no dealer on the phone; that is when this book earns its keep. One download, bookmarked and text-indexed, yours for the life of the machine.
Complete the set for your BW 100 AD-4, BW 120 AD-4, BW 100 AC-4…
