This Bomag BW 212 Training Manual PDF, the 174-page factory book 008 098 66, strips the travel, vibration and steering hydraulics of four single drum rollers down to the last test port: the 212 and 214 in smooth D-3 and padfoot PD-3 trim. Hydraulic schematics trace hose routing through the travel, vibration and steering circuits, while wiring diagrams walk the power supply, starter circuit and fault monitoring board wire by wire. Troubleshooting tables take you from a dead travel lever or a silent exciter straight to the right test port. Set injection valve opening pressure to 250 + 8 bar, and confirm charge pressure holds at least 24 bar before condemning the travel pump. A roller that quits vibrating mid-lift stalls the whole compaction plan. This bookmarked PDF, text layer intact, has you diagnosing tonight and the drum back in the pass tomorrow.

Bomag BW 212 / BW 214-3 Series Common Problems This Manual Covers
Bomag BW 212 D-3 buzzer sounds then engine dies, low oil pressure light on
Check the oil level and top up first; the sump holds 17.5 liters, listed on page 12. The monitoring board kills the engine 10 seconds after pressure drops, covered on page 140. If the level is good, test actual oil pressure at the port before condemning the sender, then trace the shut-off circuit through the fault monitoring board.
Manual Section: Electrical System p. 140Machine will not drive in either direction, travel lever moves but nothing happens
Check the travel control cable reaches mechanical neutral and gives full stroke at the travel pump, then work the fault chart on page 72. Measure charge pressure before chasing the high pressure side; you need at least 24 bar. Verify the brake solenoid valve actually releases the multi disc brakes when the lever leaves neutral.
Manual Section: Trouble Shooting Travel System p. 72Engine cranks slowly and will not fire on cold mornings, buzzer stays quiet
Clean the battery terminals and clamps; a corroded clamp starves the 12 V starter on a cold Deutz. Drain the fuel filter to clear winter paraffin separation and bleed air from the lines. If it cranks well but still won't fire, check injection valve opening pressure, spec is 250 bar on page 24, and set valve clearance to 0.3 mm inlet, 0.5 mm exhaust.
Manual Section: Deutz Diesel Engine p. 17Hydraulic oil runs hot mid-shift, hydraulic filter warning flickers on rough lifts
Blow out the hydraulic oil cooler fins with compressed air; a plugged cooler is the usual cause and takes ten minutes to fix. Verify oil level, the tank holds 60 liters. Replace the filter element if the warning showed, then check charge pressure against the 24 bar minimum on page 109 before sending the roller back into the pass.
Manual Section: Vibration p. 109Steering wheel turns hard or drum will not follow, end stops never reached
Test steering pressure at the port first; the relief valve setting is 175 bar on page 120. Run the chart on page 128 to split steering valve faults from cylinder faults. Inspect the articulated joint for seized pins and grease it before pulling the steering valve; a dry joint mimics a dead pump and wastes half a shift.
Manual Section: Trouble Shooting Steering System p. 128Frequently Asked Questions
How do I clear the warning buzzer or shutdown fault on a BW 212 PD-3?
To reestablish a defined initial condition after an engine shutdown, the ignition must be switched off before restarting. After this, the ignition must be switched off and the shut-down relay must be deactivated to enable a new starting process. p. 138
What are the replacement specifications for the air filter cartridge?
The dry air filter element should be cleaned or changed at least once per year. The safety cartridge should be changed at least every 2 years. p. 15
What are the replacement specifications for the hydraulic oil filter element?
The hydraulic oil filter should be changed at least every 2 years and after any repairs performed in the hydraulic system. p. 15
What is the correct valve clearance for the Deutz BF6M1012E engine?
The valve clearance must be checked and adjusted when the engine is cold. The inlet valve clearance is 0.3 mm and the exhaust valve clearance is 0.5 mm. p. 22
What is the opening pressure for the injection valve?
The opening pressure for the injection valve is 250 + 8 bar. When checking, ensure strict cleanliness and use only testing oil according to ISO 4113 or clean diesel fuel. p. 24
