To keep the paving train moving, a 978-page Bomag BW 191 AD-5, BW 191 ADO-5, BW 206 AD-5, BW 206 ADO-5 service manual PDF (OEM 008 401 00 EN) delivers the precise factory data required to maintain four tandem vibratory roller variants. The document maps out the entire electrical and closed-loop travel systems through detailed wiring and hydraulic schematics. A massive troubleshooting section walks you through everything from reading Deutz EMR4 fault codes to flushing the drum drive motor, so you can isolate issues in the vibration circuit before the mat cools. Factory specifications leave no room for doubt, verifying critical values like the charge pressure test port (MS) at approximately 25 bar and the backward travel pressure test port (5 MA) rated for 450 bar. Guessing at charge pressures or testing the wrong solenoid ruins expensive hydraulic components; print the bookmarked, text-searchable digital file and take the pages straight to the dirt.

Bomag BW 191 AD-5, BW 191 ADO-5, BW 206 AD-5, BW 206 ADO-5 Common Problems This Manual Covers
Bomag BW 191 AD-5 throws fault code 3058 and the front drum vibration system cuts out randomly
Inspect the vibration controller solenoid valves. Measure the coil resistance to confirm it reads approx. 6 Ω as specified on page 112. Attach a gauge to the front vibration pump and verify the start-up pressure hits approx. 380 bar on page 369 before dropping to normal operating pressure.
Manual Section: Overview of Hydraulics p. 369Machine throws fault code 1142 during heavy compaction passes and loses all forward and reverse travel
Check the travel system pressure sensor and harness for damaged pins. Test the charge pressure at test port MS to ensure it reads approx. 25 bar as detailed on page 112. If the pressure is low, inspect the closed-loop travel pump for internal wear and replace the main filter.
Manual Section: Overview of Hydraulics p. 112Engine warns of low speed signal and shuts down abruptly while rolling a hot asphalt mat
Verify the engine speed sensor connections at the main harness. Access the engine control module and confirm the unit maintains the engine rated speed of 2300 min-1 under load as listed on page 83. Check the fuel filter for restriction and drain any water from the separator bowl.
Manual Section: Trouble shooting, diesel engine p. 83Frequently Asked Questions
How do I reset an error code on the BOMAG BW 191 AD-5?
To delete stored faults, you must execute the function "Delete all stored faults". Ensure the engine is not running, enter code number 0710 (without service code 9999), and switch the ignition off and on again. All stored faults will then be deleted. p. 659
What is the torque specification for the cylinder head cover on the BW 191 AD-5?
The tightening torque for the cylinder head cover on the BW 191 AD-5 is 13 Nm (10 ft·lbf). p. 295
What is the correct oil capacity for the exciter housing on the BW 191/206 AD-5?
Each exciter housing on the BW 191/206 AD-5 takes 7.5 liters (2.0 gal us). p. 79
What is the procedure for bleeding the travel circuit on the BW 191 AD-5?
Bleeding the travel circuit requires installing pressure test hoses to the charge pressure and high pressure test ports. Operate the starter motor for approximately 30 seconds, wait one minute, and repeat until oil starts to run out of the pressure test hoses. p. 415
