Dynapac CG233HF Compaction Full Schematics Diagrams (Electrical and Hydraulic)

On a CG233HF roller that spends its life on hot mix and base courses, you’re dealing with vibration, dust, and a lot of electrical and hydraulic load. This schematic set is what I’d pull out when I need to trace a circuit or follow a hose run from one end of the machine to the other. Say the vibration won’t start but the panel lights up; with these diagrams you can follow the feed from the power source, through relays and switches, right down to the coil or valve, and decide if the problem is wiring, a bad component, or a supply issue.

Applications & Use Cases

• Track down intermittent electrical faults by tracing power and ground paths across the whole machine.
• Isolate a dead function in the hydraulic system by following line routing from pump to valve to actuator.
• Verify correct wiring after replacing a harness, relay block, or control switch.
• Confirm hose connections and flow direction after cylinder, motor, or valve replacement.
• Plan clean installation routes for add‑on work lights, beacons, or telematics without overloading existing circuits.

FAQ

Q: Can I use this on a tablet at the jobsite?

A: Yes, it’s workable on a tablet; zooming in lets you read symbols and follow lines without carrying paper.

Q: Is it worth printing parts of it?

A: Many techs print just the key pages they use often and keep them in a plastic sleeve in the service truck.

Safety Note

Always de‑energize and depressurize the machine before using these diagrams to work on electrical or hydraulic systems.
