This Bomag BW 212 Training Manual PDF, the 174-page factory book 008 098 66, strips the travel, vibration and steering hydraulics of four single drum rollers down to the last test port: the 212 and 214 in smooth D-3 and padfoot PD-3 trim. Hydraulic schematics trace hose routing through the travel, vibration and steering circuits, while wiring diagrams walk the power supply, starter circuit and fault monitoring board wire by wire. Troubleshooting tables take you from a dead travel lever or a silent exciter straight to the right test port. Set injection valve opening pressure to 250 + 8 bar, and confirm charge pressure holds at least 24 bar before condemning the travel pump. A roller that quits vibrating mid-lift stalls the whole compaction plan. This bookmarked PDF, text layer intact, has you diagnosing tonight and the drum back in the pass tomorrow.
