Changing the oil in a vibrator shaft tube or a drum drive gear is where guesswork gets expensive, and the maintenance chapter of this 110-page Bomag operator manual (OEM 008 126 71) covers both across four BW-series tandem vibratory rollers. This Bomag BW 141 AD-4, BW 151 AD-4, BW 151 AC-4, BW 161 ADCV operator manual PDF pairs a full walkthrough of the indicators and controls with procedures for crabwalk operation, vibration switching, jump-wire starting, and the pressure sprinkling system with its edge cutter nozzle. Maintenance claims the biggest share of the pages: filling capacities, the service chart, steering chain tensioning, and greasing the articulated joint. Tension the refrigerant compressor V-belt to 10 to 15 mm of deflection, and plan your fuel stops around the 160-liter tank. A belt tension guessed by feel can cost you a compressor. Buy this bookmarked, text-searchable PDF once and it stays with the roller for as long as you run it.

Bomag BW 141 AD-4, BW 151 AD-4, BW 151 AC-4, BW 161 ADCV Common Problems This Manual Covers
Bomag BW 151 AD-4 cranks strong from the seat but the engine never fires
Check that both travel levers are in neutral and you are planted in the seat; the seat contact switch shuts the engine down 4 seconds after you leave it (page 46). Verify fuel in the 160 l tank, then work the no-start rows in the troubleshooting chart on page 105. Never use ether.
Manual Section: Trouble Shooting p. 105Charge control lamp or another warning light stays lit right after startup
Stop rolling, throttle back, and read the lamp against the indicator layout on page 23. Check engine oil on the dipstick; the sump holds 10 l (page 9). If the charge control light stays on, inspect V-belt tension and follow the engine troubleshooting chart on page 105 before the next pass.
Manual Section: Indicators and Controls p. 23Engine runs hot and loses power under load after a few passes
Clean the cooling package first; blocked airflow is the usual cause on dusty lifts. Shut down, let it cool, and blow debris out of the fins from the fan side. Confirm the engine still pulls to its rated 2500 rpm (page 9), then work the overheating rows on page 105.
Manual Section: Trouble Shooting p. 105Rubber tires scuffing and tearing the fresh asphalt mat during finish passes
Fill the 800 l water tank and verify the spray system wets every tire evenly before the first pass. On the BW 151 AC-4, set tire pressure to 1 bar per page 101; low or uneven pressure kneads the mat instead of sealing it. Keep the tires wet on tender mixes.
Manual Section: Maintenance p. 101Machine creeps or loses travel drive right after startup, drums barely turning
Check the parking brake is fully released and the hydraulic oil sits at the correct mark; the system holds 60 l (page 9). Inspect hoses and fittings for seepage per the maintenance section starting on page 59, and shut down immediately if you find a leak. Low oil or trapped air stalls the drums mid-pass.
Manual Section: Maintenance p. 59Frequently Asked Questions
What is the valve clearance specification for the engine?
The intake valve clearance is 0.3 mm and the exhaust valve clearance is 0.5 mm. Before checking, ensure the engine has cooled down for at least 30 minutes and the oil temperature is below 80 °C. p. 87
What is the required oil capacity for the engine?
The engine oil capacity is approximately 10 liters, excluding the oil filter, up to the maximum oil quantity mark. p. 63
What is the correct tire pressure for the machine?
The nominal tire pressure is 1 bar (page 101). The manual gives this figure for the rubber-tired BW 151 AC-4 combination roller, and every one of its tires should carry the same pressure. p. 101
How often should the engine oil be changed?
Depending on the oil quality, the engine oil change interval is either 250 operating hours (for ACEA E2-96 or API CF/CF-4) or 500 operating hours (for ACEA E3-96/E5-02 or API CG-4/CH-4). p. 61
What is the procedure for checking the V-belt tension?
Check with thumb pressure whether the V-belt can be depressed more than 10 to 15 mm between the pulleys. For the generator V-belt, use a measuring unit to achieve a tension of approximately 450±50 N for first installation. p. 83
