A drum that quits vibrating halfway through a lift is a hydraulic problem, and this 390-page Bomag BW 211 D-3 repair manual PDF (OEM 008 193 60) is the factory route to finding it on your single drum vibratory roller. Troubleshooting diagrams trace the travel, vibration and steering circuits from symptom to failed component, backed by hydraulic schematics and complete flushing procedures for both closed loops. Supplier rebuild sections strip the A4VG and A10VG variable displacement pumps and Series 51 travel motors down to the rotary group, and the drum and oscillating articulated joint each get a full teardown chapter. Set the steering relief at 190 ± 10 bar, then confirm roughly 210 bar in the circuit before closing up. Every hour the roller sits, a lift goes uncompacted. Bookmarked and text-searchable, and detailed enough that you know exactly which piston or valving to order the first time.
