This is the Bomag service manual for the BW 211 DE-40 single drum roller, factory publication 008 919 50, written for machines from serial number S/N 101 583 45. It is a 1434 page workshop document in English, sold as a direct PDF download.
A service manual is the book for whoever actually opens the machine. When the roller quits mid-lift and there is no dealer tech to call, this is where you trace the fault: travel drive, vibration, engine, electrics, steering, worked through the test and repair sequences Bomag wrote for its own workshops. The file carries 16953 bookmarks, so moving from a symptom to the right system takes a few clicks instead of paging through hundreds of sheets.
If you keep a BW 211 DE-40 compacting fills, subgrades or trench backfill, this is the reference that gets it back in the pass.

Bomag BW 211 DE-40 Common Problems This Manual Covers
No vibration or weak amplitude
The drum runs but will not shake, or amplitude falls off and the lift stops gaining density. Causes range from the vibration drive to a worn exciter shaft, and the manual's vibration tests separate hydraulic faults from mechanical ones before you open anything.
Manual Section: VibrationRoller will not travel or only creeps
A closed loop travel circuit that loses charge pressure leaves the machine crawling or dead on the ramp. The travel drive procedures walk the pressure checks from the travel pump through to the drum drive motor so you replace the failed component, not the whole loop.
Manual Section: Travel driveBrake will not release after start-up
A spring applied brake that stays locked drags the machine down and cooks the drive. The manual covers the release circuit checks that tell you whether the fault is hydraulic supply or the brake itself.
Manual Section: Travel driveEngine cranks but will not start
Hard starting on a cold morning with the crew waiting is usually fuel supply or the shutdown circuit rather than the engine itself. The engine section gives the checks in order so you are not bleeding lines on a guess.
Manual Section: EngineIntermittent electrical faults
Gauges drop out, the starter clicks once, or the machine dies over rough ground. Wiring on a roller lives with constant vibration, and the electrics section gives the circuit tests to chase a broken connection instead of swapping parts.
Manual Section: ElectricsSteering slow, heavy or wandering
Sluggish response at the articulated joint makes a straight pass hard to hold and edges dangerous. The steering procedures cover the pressure checks and component tests that separate pump problems from cylinder and joint wear.
Manual Section: SteeringFrequently Asked Questions
Which machines does this manual cover?
The Bomag BW 211 DE-40 single drum roller from serial number S/N 101 583 45, under factory publication 008 919 50. Check the serial plate on your machine against that prefix before buying.
Is this the full factory service manual?
Yes. It is the Bomag service manual, 1434 pages in English, written for workshop level fault finding and repair rather than daily operation. It is the document a dealer technician would work from.
Does it cover the hydraulic travel drive?
Yes. The Travel drive material covers the closed loop travel circuit, from the travel pump to the drum drive motor, including the pressure checks you need when the machine will not move or loses power under load.
What engine and power does the Bomag BW 211 DE-40 run?
The BW 211 DE-40 is fitted with a water-cooled Deutz BF4M 1013 EC, four cylinders, rated at 114 kW at 2200 rpm to DIN ISO 3046. That figure sits on page 32 of the manual's technical data sheet, right above the weight and speed figures.
What are the fuel, hydraulic oil, coolant and engine oil capacities on the Bomag BW 211 DE-40?
Page 33 lists 250 litres of fuel, 60 litres of hydraulic oil, 16 litres of coolant and 10 litres of engine oil. Check those figures before a service fill instead of going off the sight glass alone.
What torque applies to the oscillating articulated joint on the Bomag BW 211 DE-40?
The technical data on page 496 gives 77 Nm and 90 Nm for the oscillating articulated joint. Torquing to the wrong one of those two figures is a common reason the joint works loose again after a repair.
