Atlas Copco CP275 Operators Manual

You’re running a CP275 rubber roller on a job site, and some Manual Transmission aftermarket PDF gave you a torque spec that snapped a hydraulic fitting. That’s a lost shift and a leak you don’t need. The Atlas Copco CP275 Operators Manual is the factory document – 110 pages of genuine OEM data keyed to your machine’s serial number. No guesses, no copied numbers from a different model. This is what the Dynapac engineers printed.

Safety – When Operating: Slope Limits and Edge Distances

Page 7 of this manual lays out the slope limits for the CP275. Exceed those and you risk a rollover. Page 8 covers driving near edges – something most operators ignore until they drop a wheel off the shoulder. The ROPS bolt torque spec on page 19 isn’t optional. Use a torque wrench, not a cheater bar. The manual tells you exactly what pattern to tighten them in. That information came from the same engineers who designed the cab.

Technical Specifications – Dimensions, Weights, Fluid Capacities

Pages 13 through 17 give you everything: overall dimensions, curb weight, working capacity, and the fluid types for the Cummins 4BTAA3.9 diesel engine. The standard lubricants table on page 10 lists the exact oil grades for different ambient temperatures. If you’re working in San Antonio summer or North Dakota winter, you need that table. The manual also includes the high‑temperature and freeze‑risk notes – page 10 again. Ignore those and you’re changing out a cracked block.

Tightening Torque: Hydraulic System and ROPS Bolts

Page 18 is where the real money is. Hydraulic system torque values – not the generic “tighten until snug” you get from third‑party crap. These are factory numbers for every fitting on the CP275. ROPS bolts on page 19 have their own torque spec because that structure holds your life together. You want a list of tools required? The manual assumes you own a torque wrench and a 24V battery charger. It’s an operator manual, not a hand‑holding guide. But it does tell you the tightening sequence – something you won’t find in any aftermarket summary.

Special Instructions – Lubricants, Freeze Protection, and Jump Starting

Page 10 covers standard lubricants, high‑pressure cleaning, and fire‑fighting procedures. Page 12 is critical: jump starting a 24V system. Do it wrong and you’ll fry the ECM. The manual’s step‑by‑step procedure tells you which cable goes where and why. If you’ve ever seen a tech smoke a control unit because he used the wrong post, you’ll appreciate having this page handy. The battery handling section on page 11 includes the exact electrolyte level check – not “top up as needed.”

Machine Description and Identification: Finding Your Serial Number

Page 21 shows where to find the product ID plate on the CP275. If you’re ordering parts, you need that number. The manual cross‑references the serial number range for your machine. Without it, you’re guessing which revision of the roller you have. The parts catalogs Atlas Copco CP275 2016 Parts Catalog – 429 Pages of OEM Specs won’t help you if you can’t identify the build date. That’s why this operator manual comes first.

Use this manual. Not some photocopy of a photocopy. The Atlas Copco CP275 Operators Manual – Factory Specs for Rubber Roller is the same document used by dealer shops. For the air compressor variant, see the Atlas Copco XAHS 146 Dd 2006 Operators Manual – Factory Specs. And if you need a primer on how drivelines work, the Manual Transmission article on Wikipedia gives you the basics – though the CP275 uses a hydrostatic system, not a manual box.

That’s 110 pages – not a single wasted page. You get the torque numbers you need, the fluid specs your machine demands, and the safety procedures that keep you alive. Nothing more. Nothing less.

Does this manual include engine overhaul specifications?

No. This is an operator manual, not a service manual. It covers operation, safety, daily maintenance, and torque specs.

Can I use this manual for daily preventive maintenance on my CP275?

Yes. It lists all standard lubricants and fluids, tightening torques, and safety checks. The special instructions section (page 10) covers high pressure cleaning, fire fighting, and battery handling – things you need to know before you start the engine. If you follow the daily procedures from this manual, you’ll avoid most common failures. The factory torque data on page 18 for hydraulic fittings alone will save you from leaks. It also tells you how to correctly jump start a 24V system – do it wrong and you fry the ECU. That’s why you keep this manual in the cab.
