Covering the BW 135 AD, BW 138 AD, and BW 138 AC tandem vibratory and combination rollers, this 478-page publication is the official Bomag BW 135 AD, BW 138 AD, BW 138 AC service manual pdf (OEM ID 008 914 44) for diagnosing and repairing your compaction equipment. The documentation anchors troubleshooting with complete wiring diagrams and extensive hydraulic schematics detailing the closed-loop travel and vibration circuits. Your technicians will find clear teardown instructions for the oscillating articulated joint, plus precise flushing procedures for the front and rear drum drives. Verify system health by confirming the travel circuit charge pressure hits 20 ±2 bar at high idle, or check that the vibration motor leakage rate stays below the maximum 0.5 l/min threshold. A roller stalled mid-mat means the whole paving train stands still, but this bookmarked and text-searchable digital manual lets you locate the exact spec you need to get the machine back in the pass.
