Dynapac CA6000, CA2500, CA2800, CA3500, CA4000 Operators Manual

I’ve been wrenching on heavy equipment for 28 years. ASE Master Tech, six bays in San Antonio, and I’ve lost count of how many times a customer brought in a roller that had been cobbled together using some photocopied aftermarket booklet. That’s not what you get here. The Dynapac CA6000, CA2500, CA2800, CA3500, CA4000 Operators Manual is the original factory document – 168 pages, printed from the same file Dynapac ships with the machine. If you’re working on a CA2500 or a CA6000, you need the spec that came from the engineer, not some third-party guess.

Safety When Operating: Edges and Slopes

This manual doesn’t waste space. Turn to the safety section and you’ll find explicit warnings for driving near edges and working on slopes. Section “Safety – when operating” covers the physics of a 12‑ton roller on a grade. It tells you the maximum slope angle and what happens if the drum loses traction. I’ve seen guys skip these pages and end up with a roller in a ditch. That’s a bill you don’t want.

There’s also a dedicated page on Roll Over Protective Structure (ROPS) and welding precautions. If you ever need to weld on the frame, you’d better read that part first. The manual explicitly says how to disconnect electrical and hydraulic systems before striking an arc – something the aftermarket reprints always leave out.

Specs You Actually Need: Weights and Tightening Torque

Technical specifications start on page 15. You get dimensions in side and top views, operating weight with and without ballast, and fluid capacities for hydraulic oil, engine oil, and coolant. Page 18 lists the exact weight of each model – CA2500, CA2800, CA3500, CA4000, CA6000 – so you know what your trailer needs to handle. The torque table for hydraulic fittings and engine mounting bolts is in the tightening torque section later in the book. That’s the kind of data that prevents you from snapping a bolt or creating a leak that takes hours to find.

Standard Lubricants and High‑Temp Fluids

One thing I appreciate about this manual is that it calls out specific grades for high ambient temperatures. Above +40°C (104°F), the standard lubricants change. The “Special instructions” chapter tells you exactly which oil to use for the Cummins QSB 4.5 engine (Tier 3 or Tier 4i) and which hydraulic fluid keeps the system from thinning out. Ignore that advice in a Texas summer and you’ll be replacing a pump before fall. Also covers fluid-filled tires – ballasting – with recommended weight concentrations.

Battery Handling and Jump Starting (24V)

These rollers use a 24V electrical system. The manual has a procedure for jump starting that includes the exact sequence of cable connections and a warning about hydrogen gas venting. I’ve watched a guy arc a wrench across a battery post and lose skin. This book tells you to connect the last cable to ground away from the battery. That’s not common sense – that’s written-in-blood procedure. Page 13 covers jump starting step by step.

Electrical System and AC Control (Optional)

If your roller has the optional Automatic Climate Control (ACC), there’s a separate subsection on page 25. The wiring diagram isn’t in this operators manual – that’s in the service manual – but the operating instructions, fuse locations, and HVAC controls are all documented. For hydraulic system pressures and test points, see page 24. That’s where they tell you the charge pressure range for the propel and vibration pumps. No guesswork.

Factory OEM vs Aftermarket: Why This Manual Wins

Every aftermarket “universal” manual I’ve seen for Dynapac rollers has wrong torque specs or omits the safety decal placement diagrams. This is the original PDF from Dynapac / Atlas Copco, printed in Sweden. The CE marking and declaration of conformity are in the front matter. The language matches the machine decals. If you’re maintaining a fleet of CA2500 through CA6000 rollers, having the OEM document means you’re working off the same paper the dealer tech uses. No translation errors, no missing pages.

Does this manual cover all five models?

Yes. It includes CA2500, CA2800, CA3500, CA4000, and CA6000 with engine variants Cummins QSB 4.5 Tier 3 and Tier 4i.

How do I interpret the torque tables?

Torque values are listed in both Nm and lb-ft in the tightening torque chapter. The manual specifies different torques for UNF/UNC bolts, metric bolts, and hydraulic adapters. Always use a calibrated torque wrench – the table assumes clean, dry threads unless otherwise noted (e.g., use anti-seize on exhaust manifold bolts). If you’re working on a CA3500 drum mount, cross‑reference the axle nut torque on page 73 (or the page indicated in the table of contents) because the value changes depending on whether you have standard or heavy‑duty bearings. I’ve seen three different values floating around online – only the factory table matches the actual shaft diameter used at the plant.

Bottom line: If you’re maintaining any of these rollers, you need the real OEM data. Stop relying on forum posts and photocopies. Get the file that Dynapac intended you to have. Access the Factory Manual from AutoRepairManuals and put it on the tablet in your shop. Your equipment will last longer, your technicians will stay safer, and you won’t have to redo a job because you guessed the torque.
