A shift on the fill doesn't wait while you hunt down which switch runs the tilt blade or where the hood release hides. The Bomag BC 473 EB-3 operator manual PDF answers that: 208 pages of factory operating instructions for this soil compactor, issued under OEM ID 008 202 81 EN. Daily checks run from engine oil and coolant through the central lubrication system, and the maintenance table lays out every 500, 1000, 2000 and 3000 hour service down to padfoot cap replacement. Troubleshooting walks you through jump starting, emergency hood operation, engine emergency mode and the full fuse assignment. Set the hydraulic oil 3 cm below the top edge of the inspection glass, and pull the engine oil filter cap to 25 Nm at each change. Nobody memorizes a fuse layout. This bookmarked, text-searchable PDF prints clean, so the pages you actually use can live on the bench and take the grease.

Bomag BC 473 EB-3 Common Problems This Manual Covers
Bomag BC 473 EB-3 engine cranks slowly or will not start on cold mornings
Test battery open-circuit voltage before cranking. A healthy battery reads 12.6 V; at 12.3 V it is already half discharged, per the values on page 186. Charge it or jump start following the jump lead procedure on page 191, connecting positive terminals first. Clean the terminals and check ground straps for corrosion.
Manual Section: Troubleshooting p. 191Machine travels slowly and dozer blade pushing power fades halfway through the shift
Check the hydraulic oil level with the machine parked on level ground. Oil should stand 3 cm (1.2 in) below the top edge of the inspection glass, as shown on page 76. Top up if low, then walk the tank and hose runs for leaks; the system holds 260 l, so a slow leak hides for days.
Manual Section: Checks Prior to Start Up p. 76Coolant temperature climbs into the red zone during long pushes up the fill
Shut the engine down and let it cool before opening the radiator cap. Check coolant level and antifreeze concentration; keep it between 35% and 50% as specified on page 134. Blow debris out of the radiator core, and remember the system holds 42 l if you end up doing a full refill.
Manual Section: Maintenance p. 134Engine loses power and exhaust smokes black when pushing a heavy lift
Check the air filter restriction indicator first. Remove the main element and blow it out from the inside with dry compressed air at no more than 2.1 bar (30 psi), per page 177. Replace the element if it is oily or torn, never wash it, and reseat the dust discharge valve before restarting.
Manual Section: Maintenance p. 177Compactor wheels packing with soil and waste, scrapers no longer clearing the tips
Adjust the scrapers before the buildup starts costing you passes. Set the inner scrapers to 0 mm and all others to 10 - 15 mm (0.4 - 0.6 in) from the wheel, then torque the fastening screws to 502 Nm, per page 182. Check the edge cutter clearance of 1 - 2 mm while you are in there.
Manual Section: Maintenance p. 182Frequently Asked Questions
How do I clear a fault on a BOMAG BC 473 EB-3?
To reset an existing fault on the central lubrication system, press the push button for 1 second. The flashing control lamp in the push button will change to a permanent light. p. 57
What are the replacement specifications for the engine air filters on a Bomag BC 473 EB-3?
The air filter may be cleaned up to six times, but it must be replaced together with the safety element at the latest after one year. The safety element itself must not be cleaned and should be replaced if the air filter is damaged, at the latest after one year, or if the air filter warning light comes on again after cleaning. p. 176
What is the tightening torque for the scraper bar extension fastening screws on the Bomag BC 473 EB-3?
The fastening screws on the scraper bar extensions must be tightened to a torque of 800 Nm (590 ft-lbf). p. 157
What is the correct valve clearance adjustment angle for the intake and exhaust valves on the Bomag BC 473 EB-3?
The valve clearance adjustment angle is 75° ± 15° for the intake valve and 105° ± 15° for the exhaust valve. p. 160
What is the engine oil capacity for the BC 473 EB-3?
The engine oil filling quantity is 21.5 liters (10 gallons US). p. 137
