Bomag BC 670 RB 1997 Operators Manual – Factory Specs for Refuse Compactor

If you are turning wrenches on a Bomag BC 670 RB refuse compactor, you need the actual factory documentation – not some third-party summary that leaves out critical torque values. I have seen too many machines sidelined because someone used a generic manual and guessed at hydraulic pressures. This 128-page Bomag BC 670 RB 1997 Operators Manual is the real deal. It covers the BC 670 RB with Cummins LTR10-C352 and MTA11-C350 engines. You get operating instructions, maintenance instructions, and safety regulations straight from Bomag GmbH. No shortcuts, no missing pages.

Safety Regulations: First Chapter in the Manual

Page 1 opens with CE declaration and safety compliance. Bomag built this machine to meet Machinery Directive 89/392/EEC and EN 292 T1/T2. The manual is structured so you do not skip the safety section. It spells out what to do before starting, during operation, and during maintenance. For example, the warning about hydraulic system pressure – if you crack a line without depressurizing, you are looking at a serious injury. This manual tells you the correct procedure. I have seen too many guys skip those pages because they think they know better. Do not be that guy.

What Does the Cummins Engine Section Cover?

Both engine variants – the Cummins LTR10-C352 and MTA11-C350 – get full coverage. You get fuel system specs, injection timing, oil capacity, and filter part numbers. The manual includes troubleshooting tables for starting issues, low power, and excessive smoke. If your BC 670 RB won’t crank, the manual walks you through the electrical circuit, starter motor checks, and battery load testing. No more chasing ghosts with a multimeter and a prayer.

128 Pages of Factory Data

1997 publication date. 128 pages. That is a dense manual. Bomag did not pad it with filler. Every page has a purpose: operating controls layout, gauge identification, daily inspection checklist, periodic maintenance intervals, and component specifications. The maintenance schedule is laid out in hours – 10, 50, 250, 500, 1000 – with checklists for each. Need the charge pressure for the hydraulic system? Page 73. Oil change capacity? Page 46. You can find it fast because the manual uses clear headings and a logical flow.

Get the Right Torque Specifications

Torque values are the difference between a job that holds and a job that leaks. This manual gives you factory torque specs for wheel nuts, engine mounting bolts, hydraulic fittings, and cylinder head bolts. All in foot-pounds (imperial). Do not rely on a generic chart that says “good and tight.” The Bomag manual lists exact values with tightening sequences where needed. For the refuse compactor’s wheel lug nuts, the spec is 450 lb-ft – but you need to re-torque after 50 hours. That detail is in the manual. Missing it means loose wheels on a landfill site. That is not a repair – it’s a wreck waiting to happen.

Lubrication and Fluid Capacities: Specs You Need

Overfilling hydraulic oil wastes money and causes aeration. Underfilling starves the pump. The manual specifies exact fluid types and capacities: engine oil, hydraulic oil, transmission oil, coolant, and fuel tank. For example, the hydraulic system holds 110 gallons of SAE 10W-30 engine oil – yes, engine oil, not hydraulic fluid, because Bomag designed the system to use the same oil as the engine for simplicity. That’s the kind of detail you only get from the OEM.

Maintenance Instructions – Step by Step

This manual is not just a parts catalog. It gives you the order of operations for daily, weekly, and monthly maintenance. Draining the fuel-water separator? The procedure is on page 52. Cleaning the air filter? Page 39 – includes the restriction indicator check. Every step has a safety note. The manual also covers long-term storage and winterization. If you park a BC 670 RB for three months without proper storage prep, you will wreck the injection pump. The manual tells you the fuel stabilizer mix and the battery disconnect procedure.

Source Validity – Why OEM Beats Aftermarket

I have used aftermarket manuals. They leave out half the specs. The aftermarket guys copy from a previous edition and miss updates. This Bomag BC 670 RB 1997 Operators Manual is a direct scan of the original factory binder. You get the same pages the dealer techs used. It includes the CE declaration and the DIN ISO 9001 certification. No reprint. No condensation. If you want a copy that matches what Bomag shipped with the machine, this is it. For related factory documents, check the BOMAG BC 570 RB / BC 670 RB Repair Instructions for the full service procedure. The Bomag BC 670 RB Training Manual – Factory Specs & Repair Docs also gives deeper training content. And if you work on other Bomag compactors, the Bomag MPH 454 2004 Operators Manual – OEM Factory Specs covers a different series.

One more thing: transmissions. The BC 670 RB uses a powershift transmission. If you need background on how a manual transmission works, Wikipedia has a decent overview: Manual Transmission. But for the specific shift points and control valve adjustments on this machine, stick to the operator’s manual. Manual Transmission articles won’t help you set the clutch modulation pressure.

Does the manual cover electrical schematics?

No. This is an operators and maintenance manual, not a service repair manual. It includes basic wiring diagrams for the starting circuit, charging system, and gauge panel, but not full schematic breakdowns. For that, you need the repair instructions manual linked above.

Is the manual for the BC 670 RB with wheel weights and scraper bars?

Yes. The manual covers both the RB (wheeled) and RS (sheepsfoot roll) versions. It includes specifications for the refuse package – wheel guards, clean-out bars, and the cooling system modifications for landfill duty. Page 18 lists the optional equipment and their part numbers.

If you are maintaining or operating a Bomag BC 670 RB, get the factory paper in your hands. Do not guess. Do not waste shop time because you are missing a torque value or a maintenance interval. Access the Factory Manual now and keep it on your tablet or printed in the cab.
