Across 256 pages, this Bomag BW 28 RH operator manual PDF (OEM 008 202 05 EN) walks you through everything the factory expects from whoever runs this pneumatic tyred roller, from the first walk-around to final shut-down. Fuse assignments, the fault code display and engine malfunction tables carry the troubleshooting chapter, while the maintenance schedule splits the machine's service life into 250, 500, 1000 and 2000 hour intervals with a procedure behind each line. Daily checks run through the water spraying system, the emulsion mixing circuit, the tyre inflation compressor and the AdBlue/DEF level before you ever release the brake. Set the tyres anywhere from 2.0 to 8.0 bar for the job at hand, and hold the scraper-to-wheel gap at a nominal 10 mm. When it's just you and a cold machine at six in the morning, this book answers what nobody on site can. Bookmarked and text-searchable, it finds the page before the mat loses heat.

Bomag BW 28 RH Common Problems This Manual Covers
Bomag BW 28 RH engine won't start or starts poorly after storage in cold weather
Check the fuel level and fill the 200 liter tank with winter-grade diesel before anything else. Work through the troubleshooting procedures on page 236 for no-start causes. If the fuel filter was just changed, bleed the system for 20 seconds before cranking, then run the engine 5 minutes to confirm steady idle.
Manual Section: Troubleshooting p. 236Tyre pressure won't hold its setting and drifts below range during compaction passes
Check pressure at every wheel before the shift starts and keep it between 2.0 and 8.0 bar (29 to 116 PSI); the limits are printed on page 75. Inspect valve stems and beads for leaks with soapy water. Check the tyre inflation compressor oil too; that reservoir only holds 0.5 liter.
Manual Section: Indicators and Control Elements p. 75Asphalt sticking to tyres, scrapers and coco mats not clearing the wheel surface between passes
Set the gap between each scraper and the wheel to 10 mm (0.4 in) as shown on page 109, and replace coco mats or brushes worn down to the holder. Verify tyre pressure sits at the nominal value for the mat; a soft tyre changes the contact patch and picks up material.
Manual Section: Checks Prior to Start Up p. 109Unsure how to check or inflate the tyres safely when the machine is fully ballasted
Stand outside the tyre track whenever you check or inflate; a tyre letting go under 28000 kg of ballasted machine is lethal. Use an air hose at least 6 meters long, per the safety instructions on page 56, and never push past the 8.0 bar maximum. Make this part of the daily walk-around.
Manual Section: Concerning Your Safety p. 56AdBlue tank frozen after overnight parking in winter, engine derates shortly after start-up
Expect the AdBlue/DEF to freeze at -11 °C (12 °F); the system thaws it on its own once the engine runs, so start up and keep working. Never add anything to the tank to lower the freezing point. Check the level during pre-start checks, and if the filter gets serviced, torque the cover to 22.5 Nm.
Manual Section: Maintenance p. 155Frequently Asked Questions
What is the meaning of the fault code display on the machine?
If the warning buzzer sounds and the central warning lamp lights up, you should read out the fault code using the INFO 1 display field. The display shows the fault code (DTC), the fault location (BSPN), and the cause of the fault (BFMI). p. 242
What is the tightening torque for the wheel studs on the Bomag BW 28 RH?
The wheel bolts must be tightened cross-wise to a torque of 500 Nm (369 ft·lbf). p. 202
What is the nominal gap between the scrapers and the wheels on the Bomag BW 28 RH?
The nominal gap between the scrapers and the wheels is approximately 10 mm (0.4 in). p. 109
What is the required tightening torque for the AdBlue/DEF filter cover on the Bomag BW 28 RH?
The filter cover for the AdBlue/DEF filter must be tightened to a torque of 22.5 Nm (16.6 ft·lbf). p. 184
What is the fuel tank capacity of the Bomag BW 28 RH?
The fuel tank has a capacity of 200 liters (53 gal us). p. 16
