Within the hour you could be walking the pre-start checks on your refuse compactor with this 128-page Bomag BC 670 RB operator manual PDF (OEM 008 160 61) propped on the fender; the same book covers the BC 670 RS. Factory instructions take you through every indicator and control element in the cab, engine starting, driving the machine, dozer blade operation with its emergency control, plus towing and transport tie-down. A maintenance chart anchors a service section filling nearly half the book, from draining the water separator to changing planetary drive oil, with engine troubleshooting notes at the back. Fill the crankcase with 36.6 liters of oil, change it every 250 operating hours, and pull the scraper fastenings to 628 Nm. A parked compactor stops the whole tipping face. This PDF carries bookmarks and a real text layer, and it prints clean, so the pages can ride to the bench and take the grease.

Bomag BC 670 RB Common Problems This Manual Covers
Bomag BC 670 RB engine cranks but will not start after sitting over the weekend
Check fuel level first; the 500 L tank listed on page 13 runs down faster than crews expect in heavy refuse. Drain the water separator as part of the daily checks starting on page 62, then bleed air from the fuel system. Work through the engine troubleshooting procedures on page 121 if starting still drags.
Manual Section: Trouble Shooting p. 121Dozer blade and travel drive respond slowly, hydraulic power fading during the first passes
Verify hydraulic oil level on the sight glass before anything else; the system holds 350 L and slow seepage shows up first as sluggish response. Inspect hoses, fittings and tank connections for leaks and tighten anything weeping. Review the hydraulic system chapter starting on page 103 before topping up with approved oil.
Manual Section: Hydraulic System and Long-Term Storage p. 103Engine temperature gauge climbing on hot days while working a dusty landfill cell
Check coolant level cold each morning; the system takes 44 L and a slow loss hides easily. Clean the radiator and hydraulic oil cooler fins with compressed air, working from the fan side out, following the procedure on page 77. Watch the gauge on the next loaded pass before trusting the fix.
Manual Section: Engine and Cooling System Maintenance p. 77Oil pressure warning light flickers at low idle after long working hours
Check engine oil level on the dipstick before every shift, as laid out in the daily checks on page 62. Top up with SAE 15W-40 and hold the 250 hour change interval; the sump takes 36.6 L, so keep stock on the service truck. If the level reads correct, inspect the pressure sender connector for corrosion.
Manual Section: Maintenance Chart and Daily Checks p. 62Loud rattle from the scraper bars and refuse packing tight between the compaction wheels
Torque the scraper fastening bolts to 628 Nm as called out in the maintenance chart check on page 65. Pry packed refuse and wire out of the wheels while you are in there, and grease the dozer blade pivot points. Tight scrapers keep the wheels clean and the machine in the pass.
Manual Section: Maintenance Chart and Daily Checks p. 65Frequently Asked Questions
How do I reset a malfunction on the central lubrication system?
To reset a malfunction on the central lubrication system, depress the push button (No. 21) for 1 second. The flashing of the control light will change to a permanent light, indicating the reset. p. 28
What are the replacement specifications for fuel filters?
The fuel filter cartridges should be changed every 250 operating hours. When installing, ensure you do not mix up the secondary filter (Filter A) and the primary filter with water separator (Filter B). p. 73
What is the correct valve clearance for the engine?
The valve clearance for the inlet valves is 0.36 mm (0.014 in) and for the exhaust valves is 0.69 mm (0.027 in). These must be checked and adjusted when the engine is cold (coolant temperature < 60 °C). p. 91
What is the tightening torque for the injection valve adjustment screws?
The tightening torque for the injection valve adjustment screws is 0.6 to 0.7 Nm (5 to 6 in-lb). Excessive tightening of the adjustment screw can damage the engine. p. 94
What is the required tightening torque for the scraper fastening screws?
The scraper fastening screws must be tightened to 628 Nm (463 ft-lb). This check should be performed every 500 operating hours. p. 112
