Vibration is the system that ages a single drum roller fastest, and this Bomag DH-3 operator manual PDF starts you there and works outward: 92 pages of factory operating and maintenance instructions (OEM 008 157 08) covering the BW 145 D-3, DH-3 and PDH-3. Beyond the vibration side, the book walks the whole machine: pre-start checks, jump-lead starting, towing after an engine failure, and a maintenance section that fills nearly half the book, from daily fluid checks out to the 5000-hour services. A fuels and lubricants table settles what to pour where. Plan on about 10.5 litres of oil at each engine change, and a new hydraulic filter element every 500 operating hours. It always stalls the same way: pass half finished, nobody on the crew sure which oil the vibration bearings take. This bookmarked, text-searchable PDF puts the answer in the lubricants table, so you order the right drum of oil the first time.

Bomag BW 145-3 Series Common Problems This Manual Covers
Bomag BW 145 D-3 engine overheats and temperature warning comes on during long compaction passes
Shut the engine down and let it cool before opening the hood. Clean packed dust off the radiator and hydraulic oil cooler fins following the 250 to 500 hour chapter starting on page 55, then check engine oil level; the sump holds 10.5 litres. Work through the overheating steps on page 87 before rejoining the pass.
Manual Section: Engine Troubleshooting p. 87Hydraulic functions turn slow and noisy, steering and drum drive feel weak under load
Check hydraulic oil level on the sight glass with the machine parked level; the tank holds 44 litres. Inspect hoses and fittings for leaks following the hydraulic maintenance guidance on page 44. Replace the hydraulic oil filter element if it is past the 500 hour interval listed on page 47, then retest under load.
Manual Section: Hydraulic System Maintenance p. 44Engine oil level drops between daily checks during the first operating hours
Check oil on level ground before every shift as shown in the daily checks chapter on page 50 and top up to the full mark; capacity is 10.5 litres. Expect higher consumption during break-in and follow the running-in instructions on page 43. If the level still falls after break-in, inspect the engine for external leaks.
Manual Section: Maintenance Chart and Daily Checks p. 50Engine cranks slowly or will not start on cold mornings at the start of shift
Check battery poles for corrosion and charge state per the battery service steps in the 250 to 500 hour chapter on page 55. Drain the fuel filter water separator during the daily checks on page 50 and confirm fuel level; the tank holds 110 litres. Then follow the no-start procedure on page 87.
Manual Section: Engine Troubleshooting p. 87Tires wear unevenly and the machine pulls or bounces on hard ground
Check tire pressure cold at 1.8 bar as listed on page 9; with water-filled tires, rotate the wheel until the valve sits at the top before gauging or you will read ballast, not air. Retighten wheel nuts to 550 Nm per page 69 so the drum tracks straight through the pass.
Manual Section: Periodic Maintenance (250-500 Hours) p. 55Drum vibration feels weak or amplitude drops off partway through the lift
Check vibration bearing oil and change it at the interval shown in the 1000 to 5000 hour chapter starting on page 63; the housing takes 2.1 litres. Verify the throttle reaches rated speed of 2650 rpm before switching vibration on. If amplitude stays low, schedule the bearing oil service before the next lift goes down.
Manual Section: Periodic Maintenance (1000-5000 Hours) p. 63Frequently Asked Questions
How do I reset the travel pump or create a bypass on the BOMAG BW 145 D-3, DH-3, or PDH-3?
To create a bypass around the travel pump for towing, you must slacken the counter nuts on both high-pressure relief valves and turn the threaded spindle in until it is flush with the nut, then retighten the counter nut. p. 40
What are the replacement specifications for the engine oil filter cartridge?
When changing the engine oil filter, clean the sealing face on the filter carrier, slightly oil the rubber seal on the new cartridge, and turn it on by hand until the seal contacts. Then, tighten the filter element for another half turn. p. 61
What are the replacement specifications for the fuel pre-filter?
When changing the fuel pre-filter, remove the hose clamps and pull the old filter out of the fuel hoses. Ensure the arrow on the new filter points towards the fuel pump to maintain the correct flow direction. p. 67
What is the correct valve clearance for the engine?
The valve clearance for the engine must be set on a cold engine. The intake valve clearance is 0.3 mm and the exhaust valve clearance is 0.5 mm. p. 63
What is the tightening torque for the wheel nuts?
The wheel nuts must be tightened in a crosswise pattern to a torque of 550 Nm (405 ft-lb). p. 69
