Atlas Copco CC722, CC7200 Operators Manual

I’ve seen too many busted knuckles and stripped threads from guys running aftermarket reprints on heavy equipment. You grab a manual off some third-party site, torque a hydraulic fitting to what you think is right, and next thing you know you’ve got a leak that takes three hours to chase. That’s why when a customer asks me for a vibratory roller manual, I tell them to get the factory document. This Atlas Copco CC722, CC7200 Operators Manual is a 111-page original OEM print, not a photocopy scrapped from a forum. It’s the same book that came with the machine from Sweden. If you’re working on a CC722 or CC7200 with a Cummins QSB 6.7 (Tier 3), this is the only reference you should trust.

Safety Instructions: ROPS and Battery Handling

The manual opens with the usual safety warnings, but Atlas Copco doesn’t mess around. Section Safety – General instructions (page 5) covers lockout/tagout, hearing protection, and proper PPE for compaction work. If you’ve ever had a battery explode in your face because you skipped the grounding sequence, you’ll pay attention to page 12’s battery handling and jump-starting procedure. That page alone saves you from acid burns and a fried ECU. The ROPS bolt torque is listed in the Tightening torque section on page 20. Don’t guess it—look it up.

Tightening Torque Specs: Page 20 Data

Page 20 has the tightening torque table for hydraulic and structural fasteners. That’s what separates a proper rebuild from a field repair that leaks six months later. The table includes values for metric bolts in different grades. I’ve seen guys use a generic chart from the internet and snap a 10.9 bolt because they applied 30% too much. Page 20 gives you the exact values Atlas Copco spec’d. If you’re torquing the ROPS bolts, that table is on page 21. Write the number down, set your wrench, and don’t argue with it.

Hydraulic System: Pressure and Fluid Specs

Hydraulic systems on these rollers run hot—ambient temps can hit 40°C (104°F) in a Texas summer. The Special instructions section (page 11) lists the exact lubricant grades and high-temperature alternatives. There’s also a warning about freeze risk if you’re working in cold climates. The hydraulic system chapter (page 19) goes through the circuit and gives working pressures. If you’re rebuilding a cylinder or replacing a hose, you need those numbers. Aftermarket manuals skip the ambient temperature addendum. This one doesn’t.

Engine Specs: Cummins QSB 6.7 (Tier 3)

The roller runs a Cummins QSB 6.7 liter four-cylinder diesel, emissions level IIIA/T3. Technical specifications start on page 15 with vibration levels at the operator station and noise readings. Page 18 has weights and volumes—curb weight, fuel tank capacity, hydraulic reservoir size. If you’re doing a fluid change, you’ll know exactly how much oil to buy. No eyeballing it. The Engine chapter in the TOC isn’t shown in the OCR excerpt, but the identification page (first page) lists the engine model. If you need injector torque or valve adjustment, that data is in the engine supplement—this manual references the OEM engine manual. Don’t try to mix fluids from two different brands because the manual says “standard lubricants” on page 11—it means factory fill specs.

3 Critical Safety Chapters You Should Read Before Starting

First: Safety – when operating (page 7) covers slopes and driving near edges. Rollovers are ugly. Second: Air conditioning (Optional) on page 9—if the cab has A/C, there’s a separate refrigerant handling risk. Third: Fire fighting on page 12 tells you where the extinguisher mount is and what agent to use. Skip any of those and you’re liability waiting to happen. I don’t care if you’ve run rollers for twenty years; the machine changes, and the manual updates. Read it.

FAQ

Does this manual include wiring diagrams?

No. This is an operators manual, not a service manual. Wiring diagrams are in the separate electrical troubleshooting document for the CC722/7200.

What torque specs are listed on page 20?

Page 20 has a tightening torque table for metric bolts and hydraulic fittings, including ROPS bolts on page 21. Values are in Nm and lb-ft for common grades (8.8, 10.9, 12.9). The table also lists tightening sequences for critical fasteners. Without that table, you risk under-torquing a hydraulic flange and blowing a hose at 3000 psi.

Is this manual for both the CC722 and CC7200?

Yes. The cover says CC722/7200. The same manual covers both models. The only difference is the serial number range; the manual covers from serial 10000325x0A004384 onward. If your machine falls outside that range, check the OEM for an update.

What engine does the CC722 use?

Cummins QSB 6.7 liter, Tier 3 (IIIA). The manual lists it on the first page. Fuel system is common rail. If you need injection timing, this operators manual directs you to the Cummins engine manual.

Access the Factory Manual directly from AutoRepairManuals and keep a printed copy in your roller’s cab. When a fitting starts weeping or the ROPS bolts need retorque after 100 hours, you’ll have the exact number from page 20. No guesswork. No forum search. Just the OEM data that Atlas Copco stamped on the drawing. That’s what pays for itself the first time you use it.
