A roller that creeps in neutral or loses vibration mid-lift has a hydraulic fault, and this 364-page Bomag BW 212 D-3, 212 PD-3, 214 D-3 and 214 PD-3 repair manual PDF, factory document 008 194 91 for these single drum vibratory rollers, exists to trace it. The connecting plan maps every test port, control solenoid and leak oil line before you hang a gauge, and troubleshooting charts walk weak drive power, overheating oil and dead vibration back to a cause. Repair chapters cover the drum and vibrator unit, the oscillating articulated joint, and full teardowns of the A4VG, A6VM and A10VG pumps and the Poclain drive motors. Confirm the 12 V, 155 Ah battery before condemning a slow starter; torque M12 grade 8.8 hardware to 88 Nm. Swapping pumps on a hunch is expensive guessing. Bookmarked, with a real text layer, the PDF takes you from symptom to spec in seconds and gets the drum back in the pass.
