Trench work stops the moment the BMP 8500 stops answering its remote, and the 132 pages of this Bomag BMP 8500 operator manual PDF (OEM 008 059 81) exist to keep that from costing you a shift on your multi-purpose compactor. Troubleshooting charts walk the engine, the Hetronic spiral-cable and radio remote controls, and the BOSS safety system fault codes in plain if-then tables, while the maintenance section lays out fuels, lubricants, and service intervals from the engine oil level check to the vibrator shaft housing oil change. Set valve clearance between 0.145 and 0.185 mm; retorque the central screw on all four drive hubs to 900 Nm. Guess at either number and you do the job twice. Bookmarked and text-searchable, this PDF rides on whatever screen travels to the trench with you.

Bomag BMP 8500 Common Problems This Manual Covers
Bomag BMP 8500 engine stalls or won't start after fuel filter change or winter storage
Check the fuel level first, then drain water and sediment from the fuel filter. Bleed air from the fuel system following the engine troubleshooting steps on page 101; air in the lines alone will stop this engine. Replace a filter that clogged in storage, then run the engine and confirm it holds its rated 2600 rpm without stumbling.
Manual Section: Engine Problems p. 101Travel speed drops and drum vibration feels weak, hydraulic oil level reads low
Check the hydraulic oil level at the sight glass and top up immediately if low, using oil with a kinematic viscosity of 46 mm2/s at 40 degrees C as listed on page 63. Inspect hoses and fittings around the travel pump and exciter drive for wet spots, wipe everything clean, then recheck after one short test pass before finishing the lift.
Manual Section: Maintenance p. 63Engine temperature climbs and overheats during long vibration passes in hot weather
Shut down, let the engine cool, then blow out the cooling fins and air intake grilles with compressed air; packed fins are the usual cause on dusty fill. Check the coolant level and top up, the system holds 4.5 l. Add fin cleaning to your routine per the maintenance schedule on page 66 whenever the site runs dry and dusty.
Manual Section: Maintenance p. 66Clunking noise from drive hubs when changing travel direction, machine tracks unevenly
Before the next shift, check the central screw on all four drive hubs; the tightening torque is 900 Nm as specified on page 79. Inspect the hub faces for fretting marks or backed-out hardware while you are there. If the clunk stays after torquing, park the machine and call service rather than running more passes.
Manual Section: Maintenance p. 79Squealing noise from engine compartment at startup, charge warning light flickers at idle
With the engine off, check the V-belt tension; deflection under thumb pressure should be 7 to 9 mm as specified on page 75. Retension a loose belt, and replace one that is glazed, cracked, or frayed at the edges. Clean any oil off the pulleys before fitting a new belt, then verify the charge light goes out at idle.
Manual Section: Maintenance p. 75Frequently Asked Questions
How do I start the BOMAG BMP 8500 after the immobilizer has been activated?
To start the engine after the immobilizer is armed, slowly enter the six-digit user code on the keypad. Press the diamond button; the immobilizer is then disarmed, and you have 30 seconds to start the engine. p. 36
What are the replacement specifications for the engine oil filter?
The engine oil and filter should be changed every 250 operating hours. When installing the new filter, slightly oil the rubber seal, turn it on by hand until the seal contacts, and then tighten the filter element for another half turn. p. 74
What is the correct valve clearance for the engine?
The valve clearance for both the intake and exhaust valves must be set between 0.145 mm and 0.185 mm. This adjustment should be performed only when the engine is cold. p. 85
What is the required tightening torque for the central screw of the drive hub?
The tightening torque for the central screw on all four drive hubs is 900 Nm. This should be checked every 250 operating hours. p. 79
How do I bleed the fuel system after changing the fuel filter?
After changing the fuel filter, open the bleeding screw on the fuel filter and crank the engine with the starter until fuel runs out without air bubbles. Then, retighten the bleeding screw. p. 82
What exactly do I receive with this Bomag BMP 8500 Operator Manual?
Delivery is instant: a 132-page searchable PDF is yours the second checkout clears. Laptop, tablet, or phone, all fine.
