A tandem roller that creeps in neutral or loses vibration mid-mat leaves a whole paving train standing, and the Bomag BW 180 AD repair manual PDF (OEM 008 912 53) is the factory answer: 326 pages on the tandem vibratory roller, from pressure tests to full drum teardown. Flushing schematics map the front and rear drum drives and the vibration circuit, while the troubleshooting diagram traces each symptom back to the failed component. Supplier documentation fills the back half of the book, rebuilding the A4VG and A10VG travel pumps, MS/MSE drum drive motors and the A2FM 32 vibration motor down to the rotary group. Check the steering circuit against its 200 ±10 bar nominal, and confirm the brake releases at 26 bar before you condemn the drive. Every hour this machine sits, the lift waits. Bookmarked and text-searchable, the PDF puts each of those sections one tap away.

Bomag BW 180 AD Common Problems This Manual Covers
Bomag BW 180 AD randomly stops traveling after several minutes of work, drive cuts out intermittently
Check charge pressure first: the travel circuit needs 26 bar to hold the brake released, so a pressure drop kills drive instantly. Follow the travel performance diagram on page 84 while the fault is active. Wiggle-test the brake solenoid and seat switch connectors with the engine warm; servo control current must reach the 350 mA minimum step current.
Manual Section: Trouble Shooting Diagram: Travel Performance p. 84Parking brake will not release consistently, machine refuses to move when travel lever engaged
Measure brake releasing pressure at the drum drive motor; nominal is 26 bar per the chart on page 84. If pressure is low, check charge pressure at the travel pump, then test the brake valve solenoid for voltage at the coil. Clean and re-seat the connector before replacing parts; corroded pins mimic a dead solenoid.
Manual Section: Trouble Shooting Diagram: Travel Performance p. 84No vibration on either drum or vibrator shaft speed drops under load
Check vibration pump start-up pressure; it must reach 380 bar when vibration is switched on. Work through the vibration system troubleshooting diagram to isolate the pump, motors, or control unit. If the exciter housing is noisy, check vibrator shaft end float against the 1.0 to 3.3 mm limit on page 95 before condemning hydraulic parts.
Manual Section: Trouble Shooting Diagram: Vibration System p. 95Hydraulic oil overheats above 90 degrees C after an hour of continuous vibration passes
Check hydraulic oil level first; the system holds 60 l (page 18), and a low tank aerates and heats fast. Clean the cooler fins with compressed air. Test relief settings in the travel circuit; the pump limits at 440 bar, and a valve held open dumps heat constantly. Verify the thermostat and flushing valves shift correctly.
Manual Section: Trouble Shooting Diagram: Hydraulic Oil Overheating p. 90Machine creeps forward with the travel lever in neutral, brake drags on stop
Follow the machine-in-neutral diagram on page 83, then adjust the neutral position of the travel pump servo per the procedure in Tests and Adjustments starting on page 15. Disconnect the control cable first to prove whether the fault is in the pump or the linkage. After adjustment, confirm charge pressure holds 26 bar and the drum stays still.
Manual Section: Trouble Shooting Diagram: Machine in Neutral p. 83Frequently Asked Questions
How do I clear fault codes on a BOMAG BW 180 AD?
To delete stored faults on the BW 180 AD, ensure the engine is not running. Enter code number 710 on the display module to clear all stored faults. p. 54
What are the torque specs for M12 screws with strength class 8.8 on a Bomag BW 180 AD?
For screws with a metric unified thread and a strength class of 8.8, the tightening torque for an M12 screw is 88 Nm (65 ft-lb). p. 11
How do I check the leakage rate of the vibration motor?
To check the leakage rate, disconnect the leak oil and flushing oil hose, connect a leak oil hose to the motor's leak oil port, and measure the leak oil over a period of one minute. The nominal value is a maximum of 1.5 litre/min. p. 34
What is the nominal low idle speed for the engine?
The nominal low idle speed for the engine is 950 ±50 rpm. p. 16
What is the procedure for adjusting the machine type on the ESX-control?
To adjust the machine type, enter code number 725 on the display module to activate the function. Select the correct code from the table provided in the manual, enter it, and then enter code 726 to permanently store the new machine type. p. 39
