An 815-2 that won't take asphalt with a full truck waiting is a whole paving train going nowhere, and most of those stops trace back to something the operator's book covers. This 76-page Bomag 815-2 operator manual PDF (OEM 0852805) is the factory operating and maintenance book for the self propelled paver. Its operating chapter walks you through loading and drive-off, starting, steering and speed controls, conveyor and auger drives, crown and valley control, screed heaters, and the vibratory screed, while maintenance fills roughly the back third of the book with engine oil, air filtration, and cooling system service. Keep cleaning air on the primary filter element at 72 psi, and retighten your track pad hardware to 68-80 ft-lbs dry after the first 50 to 100 hours. A torque figure pulled from memory is how track pads walk off mid-shift. Bookmarked and text-layer searchable, this PDF goes wherever the paver is parked.

Bomag 815-2 Common Problems This Manual Covers
Bomag 815-2 paver engine cranks slow or won't start first thing on cold mornings
Test the battery before chasing fuel problems; the machine needs a full 12 V, 800 CCA battery, and a weak one cranks slow long before it dies. Then check fuel level and drain the water separator. If the pre-filter is dark, spin on a new one and torque it to 34 N•m per page 62.
Manual Section: Fuel System Maintenance p. 62Engine temperature gauge climbing into the red halfway through the afternoon paving pass
Check coolant level with the engine cold; the system holds 13 liters total. Inspect the radiator core for asphalt fines and blow it clean from the fan side with compressed air, keeping supply pressure below 30 psi as page 65 warns. Squeeze the radiator hoses and replace any that feel soft or spongy before the next pull.
Manual Section: Cooling System Maintenance p. 65Engine down on power and blowing black smoke under load with a full hopper
Check the air restriction indicator first. Remove the primary filter element and clean it with compressed air at no more than 72 psi, blowing from the inside out per page 58. Never clean the secondary element; replace it. Reset the indicator, run the engine under load, and recheck restriction before loading the next truck.
Manual Section: Engine Air Filtration p. 58Mat texture porous and coarse behind the screed extensions on wide pulls
Check the screed extension match height first; an extension set low drags the mix and leaves open texture, worst at the full 15 ft paving width. Adjust the match height, then set the angle of attack turnbuckles so the depth cranks respond. Run a short test pass and read the texture before the plant sends more trucks.
Manual Section: Screed Extension Match Height AdjustmentTrack drive chain slapping and jumping teeth when loading onto the trailer
Reset the spring tension on the track adjuster, then set the drive chain per page 49. While you are in there, check the track pad hardware; the bolts loosen during the first 50-100 hours and need retightening to 68-80 ft-lbs dry. Adjust both tracks evenly so the machine tracks straight on the next pass.
Manual Section: Track Chain Adjustment p. 49Frequently Asked Questions
What are the torque specifications for the valve locknut?
The locknut torque value for the valve adjustment screw is between 29 ft-lb (39 N•m) and 36 ft-lb (49 N•m). p. 71
What is the procedure for adjusting the track chain tension?
To adjust the track chain, increase the grease pressure to 1500 psi until the distance from the center of the center track roller to the front of the tension pump is 13.5 inches. The distance from the bottom of one track pad to the outside frame rail should then be 5.75 inches. p. 49
What are the valve clearance specifications for the engine?
The valve clearance for the intake valve is 0.35 mm (0.014 in) and for the exhaust valve is 0.50 mm (0.020 in) when the engine is hot or cold. p. 71
What is the required fuel capacity for the paver?
The fuel tank capacity for the BOMAG 815-2 is 132.5 liters (35 gallons). p. 20
How often should the hydraulic system oil be changed?
The hydraulic system oil should be changed annually or every 800 hours of operation. p. 51
