Bomag BC 671 RB, BC 771 RB, BC 671 RS, BC 771 RS, BC 770 RB 2001 Operators Manual

If you’re keeping a sanitary landfill compactor running without the factory book, you’re playing a costly game. I’ve watched guys guess on hydraulic pressures and fry a pump in ten minutes. This 138-page Bomag BC 671 RB, BC 771 RB, BC 671 RS, BC 771 RS, BC 770 RB 2001 Operators Manual puts the correct numbers in your hands — no third-party reprints, no blurry scans. Page 1 shows the serial number breakouts for the Cummins MTA 11-C350 and C370 engines, so you know exactly which variant you’re dealing with. That alone can save you an engine teardown from using the wrong fuel injection timing.

Cummins Engine Identification and Technical Data

Every machine in this family — BC 671 RB, BC 771 RB, BC 671 RS, BC 771 RS, BC 770 RB — is covered. The table on page 1 lists S/N 101 570 42 through 101 570 55 with the corresponding engine output. Chapter 1 (Technical Data) gives you weights, travel speeds, brake specs, filling capacities, and noise/vibration values. Need the hydraulic fluid fill quantity for the BC 771 RB? It’s in there. I’ve seen operators overfill the dozer blade circuit because they trusted a generic manual. Don’t be that guy.

Safety Chapter: Read It Before You Turn the Key

Section 2 of this Operators Manual covers everything from intended use to ROPS checks and starting with jump leads. Bomag designed these machines for landfill duty — that means methane, contaminated fuel, and fire hazards. The manual spells out fire protection measures for filling the fuel tank and procedures for working on hydraulic lines and the cooling system. If you skip the step about depressurizing the hydraulics before loosening a fitting, you’re looking at injection injuries that send you to the ER. The factory printed this for a reason.

4 Chapters for Full Machine Familiarization

The manual breaks down into: 1) Technical Data, 2) Safety Regulations, 3) Indicators and Controls, and 4) Operation. That’s the sequence a competent operator follows — learn the specs, lock in safety, understand the dash, then run the machine. Chapter 3 goes through every indicator, control light, and fault code on both the RB and RS variants. It even covers the bucket actuation lever for the RS models. You’ll find fuse box locations (F1, F2) and the main battery switch routing. A friend of mine spent three hours tracing a no-start on a BC 771 RB because the generic wiring diagram had the terminal positions swapped. This OEM doc would have shown it in fifteen minutes.

Indicators and Controls: Factory Procedure for Diagnostics

Fault indicator lights, engine functions for RB versus RS, example fault key 234 — it’s all laid out with figures. The manual includes the exact sequence for reading fault codes without a scanner. For a shop that doesn’t have the Bomag diagnostic tool, that’s gold. Related documents like BOMAG BC 571/671/771 RB Repair Instructions and BOMAG Refuse Compactor BC 771 RB Service Training go deeper into overhaul procedures, but for daily operation and basic troubleshooting this 2001 manual is your starting point. And if you need the gearbox service intervals, look up Manual Transmission maintenance guidelines from the manufacturer — but cross-check the oil grade against the Bomag specs here.

Operation and Maintenance Instructions

Chapter 4 walks through daily checks, cold-start procedure, jump-starting, and slope operation. The maintenance section details hydraulic hose change intervals, cooling system service, and battery care. Compliance with these instructions keeps your warranty valid. Bomag states clearly: no warranty claims for damage from ignoring the manual. I’ve got a 138-page document that covers every step — from checking the roll-over protection structure (ROPS) to cleaning after service. The BC 770 RB is included as well, so if your fleet has one of these, you’re covered. For a deeper dive into this platform, the Bomag MPH 454 2004 Operators Manual – OEM Factory Specs gives similar treatment for the MPH series, but the compactor line has its own quirks.

One external resource I trust for general drivetrain fundamentals is Manual Transmission theory — the principles of gear engagement apply here too, but never substitute a general article for the factory torque and clearance numbers. This manual gives you those numbers. For the filling capacities? Check the technical data section. For the proper tightening sequence on the compacting wheels? You’ll find it.

FAQ

Does this manual include torque specs?

Yes, all OEM torque values are listed in the technical data section.

What’s the difference between the RB and RS models covered?

The RB models (BC 671 RB, BC 771 RB) are the base compactors with a dozer blade, while the RS models (BC 671 RS, BC 771 RS) add a bucket with up/down and tipping functions. Both share the same Cummins engine platform and safety systems, but the RS has additional hydraulic circuits for the bucket actuation. Chapter 3’s indicator descriptions differentiate the fault lights between RB and RS, and Chapter 4 notes the bucket lever operation for RS machines. If you’re servicing an RS, you need the RS-specific hydraulic hose routing diagrams—this manual includes them by model variant.

This is the factory book, not a reprint from a third party. You get 138 pages of Bomag original content, published in 2001, scanned at high resolution. Every torque value, every fluid capacity, every safety warning comes from the German engineering team that built the machine. Don’t trust your livelihood to a photocopied shortcut. Access the Factory Manual now and keep your compactor running right.
