Within the hour you could be through your pre-start checks, seat adjusted and Evib line graph up on the display, with this 210-page Bomag BW 226 DH-4i BVC operator manual PDF (OEM 008 076 41) open in the cab of your single drum roller. Operation takes the biggest share of the book: starting, driving, DPF regeneration, switching vibration on and off, and a full Variocontrol measuring pass through to printing the compaction data. Maintenance runs nearly as long, from ten-hour fluid checks to the 2000-hour hydraulic oil change, with BVC/BTM05 fault code readout and fuse assignment covered under troubleshooting. Set V-belt deflection at 10 to 15 mm; before towing a dead machine, torque the travel pump's high pressure relief valves to 70 Nm. A roller stopped mid-lift holds up the whole cell. Print what you need, let those pages take the grease, and keep the bookmarked file clean.

Bomag BW 226 DH-4i BVC Common Problems This Manual Covers
Bomag BW 226 DH-4i BVC engine cranks but will not start after refueling
Check fuel level first; the tank holds 340 liters and the pickup can draw air on a grade when it runs low. Verify the electronic immobilizer accepted the key and the travel lever is in neutral. Then work through the troubleshooting procedures starting on page 184 before calling the dealer.
Manual Section: Trouble Shooting p. 184Coolant temperature warning comes on during long vibration passes in hot weather
Shut off vibration and let the engine cool at idle before stopping it. Clean the radiator core with compressed air, blowing from the fan side out. Check V-belt tension; deflection under thumb pressure should be 10 to 15 mm (0.4 to 0.6 inches), per page 143. Top up coolant only with the engine cold.
Manual Section: Maintenance p. 143Drum vibration will not switch on or amplitude feels weak on the lift
Check the hydraulic oil level with the machine on level ground; the system holds 83 liters and a low tank starves the exciter circuit first. Verify the amplitude preselect and BVC settings on the operator panel, shown on page 31. If oil and settings are correct, note any fault display and stop before the mat cools.
Manual Section: Display and Control Elements p. 31Low engine oil pressure warning shows briefly at startup on cold mornings
Shut the engine down and check the dipstick with the machine parked level. Fill to the upper mark with the approved grade; the engine holds 15.5 liters, and the fuels and lubricants table on page 129 lists the correct viscosity for the season. If the warning returns with a full sump, do not restart the engine.
Manual Section: Maintenance p. 129Frequently Asked Questions
How do I clear fault codes on the BOMAG BW 226 DH-4i BVC?
To clear faults, press button F8 (DELETE) on the Variocontrol display. Note that if you are calculating the increase of a measuring value on a track, you should only press the F8 button when changing the track. p. 48
What is the torque specification for the wheel nuts on the BW 226 DH-4i BVC?
The wheel nuts must be tightened cross-wise to a torque of 550 Nm (405 ft-lb). p. 164
What is the correct engine oil capacity for the BW 226 DH-4i BVC?
The engine oil filling capacity is 15.5 liters (4.1 gal us). Always ensure the oil level is between the MIN and MAX marks on the dipstick. p. 129
What is the valve clearance adjustment angle for the engine?
The valve clearance adjustment angle is 75° ±15° for the intake valve and 120° ±15° for the exhaust valve. p. 166
How often should the hydraulic oil filter be replaced?
The hydraulic oil filter element must be replaced every 500 operating hours, or after major repairs in the hydraulic system. p. 127
