Diagnosing the Sauer-Danfoss hydrostatic drives and screed depth controls takes precise data, which is exactly what fills the 364 pages of this Bomag 815-2 repair manual pdf (OEM ID 0852806) for your self-propelled paver. Factory documentation lays out complete hydraulic schematics for the 800 series alongside dedicated electrical circuit breakdowns. Detailed teardown procedures guide you through servicing the track drive assemblies, Fairfield torque-lock brakes, and conveyor bed removal without damaging components. Routine maintenance charts dictate exactly when to act, instructing you to swap the pressure filter after the first 50 hours before moving to a 200-hour interval, while securing track pad hardware to a strict 68-80 ft-lbs. When you are alone on the mat with a stalled machine and no one to ask, having this bookmarked, text-searchable file ensures you can trace the fault and order the right part number the first time.
