Dynapac CP2100, CP2100W Operators Manual – 113 Pages of OEM Specs

Description

I’ve seen too many guys try to run a pneumatic tire roller with a photocopied set of instructions from the dealer’s coffee table. That gets a man hurt or a machine wrecked. The Dynapac CP2100, CP2100W Operators Manual is the actual factory document – 113 pages of what Atlas Copco wrote for the guys who built it. If you’re turning wrenches on a CP2100 or the wide-wheel CP2100W, this is what you need on the tool box, not a third-party summary that leaves out half the safety decals.

Technical Specifications – Dimensions

Page 9 opens the technical data with dry numbers: engine make, tire layout, operating weight. The dimensions page (page 10) gives you the exact width, wheelbase, and turning radius in both inches and millimeters – none of that rounding-up nonsense. If you’re hauling this rig on a lowboy, you need those numbers. I’ve had shop owners order the wrong trailer because some online PDF said “approx 8 ft wide.” The OEM manual doesn’t approximate a thing. It also lists the serial number range for both the CP2100 and CP2100W, so you know which machine this book actually covers.

Interlock/Emergency Stop/Parking Brake – Factory Procedure

The interlock system on these rollers will lock you out cold if any safety gate or seat switch is open. Page 50 diagrams exactly how the emergency stop kills hydraulic pressure and sets the parking brake. You don’t guess your way through that sequence – the manual tells you the order of engagement and which relays to check if the brake won’t release. It also explains the override procedure for flat-tire towing. Use a generic manual and you’ll be hunting for 30 minutes; this one hands you the step order on a silver platter. Related manuals for other Dynapac models include the Dynapac SD2550CS SD2550C Operators Manual – Factory Specs & Safety and the Dynapac CP 21, CP 22, CP 27, CP 30 Operators Manual – Factory Specs.

Preventive Maintenance Schedule – Every 10, 50, 250 Hours

Starting on page 70, the manual breaks scheduled maintenance into hourly intervals. Daily at 10 hours: tire pressure check, grease fittings, fluid levels. At 50 hours: wheel-bearing inspection and belt tension. At 250 hours: hydraulic filter replacement and brake adjustment. Each procedure has a tool list – you won’t find “use a generic puller” because the manual names the bearing splitter you need. The lubricant specs on page 62 call out straight 30-weight diesel engine oil for the vibratory bearings. If you’re a home-garage guy who thinks any grease works, this section will set you straight. I’ve seen one over-lubed bearing seize because a guy skipped the grease type. Don’t be that guy.

Does This Manual Cover the CP2100W Model?

Yes. The title says CP2100 / CP2100W, and the table of contents treats them as the same base machine with different tire widths. Page 16 shows identification plates for both models – serial numbers, product codes, and emissions certification (Tier III vs Tier IV). The wiring diagrams and hydraulic schematics are the same, but the CP2100W section adds a note about wider turning radius on page 44. If you need the factory specs for the pavement edge roller, this manual has every line. Aftermarket manuals often lump both into one vague chart and miss the width-specific parking brake cable routing. This one doesn’t.

Source Authenticity – OEM vs Aftermarket Documentation

This is a factory print from Atlas Copco Dynapac, not a scanned copy with missing pages. The safety decals on page 12 are photographed in color with position callouts – critical for machines that have been repainted and lost their stickers. The torque values for wheel lugs and hydraulic flange bolts are in the maintenance section, not buried in an appendix. I’ve been burned by aftermarket manuals that reprint specs for a different engine variant. This one matches the Cummins QSB 3.3 and QSF 3.8 exactly. For context on how a manual transmission works in a paving train, see the Manual Transmission article on drivetrain basics, or the Manual Transmission overview for older equipment. But for your Dynapac roller, stick to the OEM book. Also check the Dynapac SD1800W Operators Manual – Factory Specs for Pavers for complementary paving equipment.

Q1: What engine does the CP2100 use?

Cummins QSB 3.3 (Tier III) or QSF 3.8 (Tier IV). The manual covers both with separate fuel-system specs.

Q2: Does this manual contain torque specs for wheel nuts?

Yes, in the scheduled maintenance table on page 65. It lists socket size and ft-lbs for the lug nuts and axle flange bolts. Do not use a generic torque chart from a truck forum – the Dynapac hub design requires a different value than a standard semi trailer.

Q3: Is this the same manual the dealer gives to mechanics?

It is the same document. The part number 4812316022EN is the identical PDF that Atlas Copco distributes through their service network. I’ve had dealer techs confirm the layout matches their in-shop copy. The only difference is you’re not paying the dealer markup. The manual includes the full operation section before maintenance – things like how to warm up the hydraulic oil, the proper transport position for the tow bar, and the interlock override for emergency towing. That’s information a dealer tech would read during training, not something you find in a parts catalog. If you want to do maintenance that doesn’t void your warranty, use the same paper they do.

Q4: Does it cover towing procedures?

Yes, pages 56-58 detail front and rear tow points, required safety chains, and the brake release procedure for dead towing.

You’re not going to find a better source of truth for keeping a CP2100 or CP2100W in the rolling line. The factory manual gives you the oil grades, filter cross-references, and safety labels that keep the job site OSHA-compliant. Access the Factory Manual and put it on your phone or tablet – keep the grease off the pages.
