If the roller on your job is a BW 211 D-3, this Bomag BW 211 D-3 Training Manual PDF fits it: 147 pages, OEM ID 008 099 07, with travel motor coverage split by serial number, up to S/N 101 580 37 1080 and from 1081 onward, so both build runs are in here. Wiring diagrams trace the power supply, ignition and starter circuit, brakes and travel speed range selector, while the hydraulic schematic maps the closed-loop travel pump, vibration drive and steering. Troubleshooting tables walk you from symptom to test port across the travel, vibration and steering circuits. Set inlet valve clearance on the Perkins diesel at 0.2 mm, outlet at 0.45 mm, and check the travel pump relief against its 475 bar limit. One missing pressure spec can park a roller between passes. Pay for this bookmarked, text-layer PDF once and it is yours for the life of the machine.

Bomag BW 211 D-3 Common Problems This Manual Covers
Bomag BW 211 D-3 rolls with travel lever in neutral, machine won't stay put on grade
Check the mechanical and hydraulic neutral position of the travel pump before condemning parts. Follow the travel system troubleshooting steps starting on page 55, then verify the control linkage returns fully to center. With gauges on the test ports, confirm the high pressure relief holds at 475 bar and readjust pump neutral until the drum sits still.
Manual Section: Trouble shooting travel system p. 55Roller will not travel in either direction, engine runs fine, drum stays dead
Verify the multi disc brakes are actually releasing before tearing into the pump. Work through the no-drive chart on page 55, and check hydraulic oil level first; the tank holds 60 l. Then gauge the travel circuit at the test ports and compare readings against the values on page 9 before condemning the travel pump or drum drive motor.
Manual Section: Trouble shooting travel system p. 55Steering feels stiff and heavy, sometimes machine also refuses to travel until restarted
A stiff wheel is a pressure question, so answer it with a gauge and not a parts order. Connect one per the procedure on page 119 and hold the wheel against the end stop; nominal is 225 bar, plus or minus 15 bar. A low reading points to the steering and charge pump, which also feeds the travel circuit and explains the intermittent no-drive.
Manual Section: Checking the steering pressure p. 119Engine overheats, coolant temperature climbing halfway through the lift
Clean the cooling fins and radiator with compressed air at the end of every shift on dusty fill. Check coolant level cold; the system holds 16 l. Inspect the fan V-belt for glazing and correct tension, then check the cooling circuit per the engine section starting on page 21 before putting the machine back in the pass.
Manual Section: Perkins Diesel Engine p. 21No vibration in high or low amplitude, exciter stays silent when vibration switched on
Hydraulic oil level and condition come first; the tank holds 60 l, and the hydraulic oil filter should be changed at minimum every 2 years. Then work through the vibration section starting on page 80: test the vibration pump and motor at their ports and inspect the exciter shaft drive before splitting the drum.
Manual Section: Vibration p. 80Frequently Asked Questions
What are the common failure causes when a Bomag BW 211 D-3 won’t travel?
Start with the control cable, the charge pressure and the steering/charge pump. Check the cable for a break or a detached end, gauge charge pressure against the nominal 25 +/- 1 bar, then inspect the high pressure relief valves. The 'Trouble shooting travel circuit' section takes these faults in order. p. 56
How often should the hydraulic oil filter be changed on the BW 211 D-3?
The hydraulic oil filter should be changed at least every 2 years and after any repairs are performed on the hydraulic system. When replacing, ensure you use only the original filters specified in the operating and maintenance instructions to prevent severe damage to engine or hydraulic components. p. 20
What is the correct valve clearance for the Perkins 1006-60T engine?
For the Perkins 1006-60T engine, the intake valve clearance should be set to 0.2 mm, and the exhaust valve clearance should be set to 0.45 mm. These measurements must be checked and adjusted on a cold engine at the intervals specified in the maintenance instructions. p. 25
What is the required engine oil capacity for the BW 211 D-3?
The engine oil capacity for the BW 211 D-3 is 13 liters. The recommended oil type is SAE 15W-40, meeting API SJ/CF specifications. p. 10
What is the nominal charge pressure for the travel system?
The nominal charge pressure for the travel system is 25 +/- 1 bar. The closed hydraulic circuit will not work properly without it, and you can read it at the charge pressure test port. p. 65
Is this Bomag BW 211 D-3 manual a PDF I download?
Delivery is instant: a 147-page searchable PDF is yours the second checkout clears. Laptop, tablet, or phone, all fine.
Am I able to print pages from this Bomag BW 211 D-3 manual?
