When the paving train is waiting on density and the roller shuts down mid-mat, this 822-page Bomag BW 120 SL-5 service manual PDF (OEM 008 401 24 EN) provides the factory data to get your BW 100 and 120 AD-5, AC-5, and SL-5 tandem vibratory rollers moving again. Detailed hydraulic schematics trace the closed-loop travel and vibration circuits so you can accurately diagnose pressure losses. The troubleshooting chapters cover the entire electrical system, including CAN bus networks and central electrics, backed by clear wiring diagrams to pinpoint sensor faults. During reassembly, secure the drum drive motor using a mounting torque of 211 Nm and confirm the main battery fuse is rated at 80 A. There is nothing worse than being alone with a dead machine and no one on the crew to ask for help, but buying this searchable, bookmarked file means the exact answers are yours to keep for the life of the roller.
Complete the set for your BW 100/120 AD-5, AC-5 and SL-5
