Bomag issued document 008 201 76 EN as the factory operating and maintenance book for the BW 226 BVC-5 single drum roller, and this 244-page Bomag BW 226 BVC-5 operator manual PDF is that exact publication. The maintenance section fills roughly a third of the book, walking you from 250-hour checks on the exciter housing and drum drive reduction gear out to 2000-hour hydraulic oil and coolant changes. Fuse assignment charts and jump-start instructions back up the troubleshooting pages, towing the machine sits with the emergency procedures, and the BVC measuring pass gets its own coverage, EVIB line chart included. When you retighten the wheel nuts, pull them to 550 Nm; the axle mounting bolts on the frame take 800 Nm. A roller that won't hold amplitude mid-lift stalls the whole compaction schedule. Bookmarked and text-searchable, this download tells you which oil, coolant and filter to order before the machine is even on the ramp.

Bomag BW 226 BVC-5 Common Problems This Manual Covers
Bomag BW 226 BVC-5 engine cranks but will not start on the first shift of the morning
Check the fuel gauge first; the tank holds 280 litres and runs dry faster than crews expect on long fill jobs. Refuel, then work through the troubleshooting procedures starting on page 228. If the starter stays silent instead of cranking, check the 30 A starter fuse F157 on page 231 before calling anyone.
Manual Section: Troubleshooting p. 228Drum vibration weak or cuts out completely halfway through a pass on the lift
Run the engine to full throttle and confirm it holds the 2300 min-1 rated speed; low engine speed kills exciter frequency before anything else does. Check the vibration selector switch and indicator lamps on the instrument cluster, described from page 65. If vibration still fails, note any fault code and check the central electrics fuses on page 231.
Manual Section: Indicators and Control Elements p. 65No travel response in either direction after startup even though the engine runs normally
Verify the emergency stop is released and the parking brake is off. Check hydraulic oil on the sight glass during the pre-start checks on page 89; the system holds 75 litres and a low tank starves the travel circuit. If the machine still will not move with fluid levels and controls correct, that is a service call, not a shift fix.
Manual Section: Checks Prior to Start Up p. 89Engine down on power and will not pull rated speed under load on the grade
Check the air filter service indicator and swap the cartridge if it shows restricted; follow the intervals in the maintenance schedule. Check the engine oil level too; the fill quantity is 15.5 litres, and overfilling drags the engine down as surely as a dirty filter. A healthy engine pulls to 2300 min-1 at full throttle.
Manual Section: MaintenanceWarning light comes on in the instrument cluster during compaction and stays lit
Stop at the end of the pass and identify the light against the instrument cluster table on page 65. Check engine oil and hydraulic oil levels; fill quantities are 15.5 litres and 75 litres, listed on page 160. If the light stays lit with fluids correct, shut down and work the troubleshooting remarks on page 227.
Manual Section: Troubleshooting p. 227Frequently Asked Questions
What do the warning lights mean on a BOMAG BW 226 BVC-5?
The instrument cluster contains various warning lamps. For example, the 'Air filter warning lamp' lights up if the air filter is blocked, requiring cleaning or replacement. The 'Coolant temperature warning lamp' indicates engine overheating, which will reduce engine power; you should run the engine at idle speed or shut it down to clean the radiator. p. 67
What are the replacement specifications for the fuel filter?
The fuel filter should be replaced at the latest after one year. When replacing, ensure strict cleanliness, as air in the fuel system can cause irregular engine running or stalling. After work, you must bleed the system and perform a 5-minute test run in idle speed or low load to check for leaks. p. 179
What is the tightening torque for the axle mounting bolts?
When retightening the fastening of the axle on the frame, you must check all fastening nuts on the axle mounting bolts for a tight fit. The required tightening torque is 800 Nm (590 ft·lbs). p. 203
What is the correct tightening torque for the wheel nuts?
The wheel nuts must be tightened in a cross-wise pattern. The specified tightening torque for the wheel nuts is 550 Nm (405 ft·lbs). p. 203
What is the required belt tension for a new V-belt?
For a new V-belt during initial assembly, the nominal belt tension should be 400 N (90 lbf) when cold. After a running-in time, in the case of reassembly, the tension should be 300 N (67 lbf). p. 170
