Dynapac CA280 Compaction Full Schematics Diagrams (Electrical and Hydraulic)

On a Dynapac CA280, you’re usually working on road bases, parking lots, or pads where downtime costs money and everything is covered in dust and vibration. This full electrical and hydraulic schematic is what I’d keep handy when I need to trace how power or oil is supposed to flow through the roller. If, for example, the vibratory drum won’t engage but the engine runs fine, I’d use this to follow the signal from the switch through the wiring and hydraulic control path to isolate where it dies.

Applications & Use Cases

• Trace electrical circuits from the battery to switches, relays, and actuators to pinpoint no-start or dead-function issues.
• Follow hydraulic lines and control paths to verify correct routing when chasing weak or uneven compaction force.
• Confirm connections after component replacement so sensors, coils, and valves are reconnected correctly.
• Compare actual machine wiring/hoses to the schematic to spot previous field modifications or misrouted lines.
• Plan diagnostic steps before tearing into components, reducing guesswork and unnecessary parts swapping.

FAQ

Q: Can I zoom in on small circuit details on a tablet or laptop?

A: Yes, the schematic can be zoomed so you can read wire and line paths clearly right at the machine.

Q: Is this worth printing, or should I keep it digital only?

A: Many techs do both—print key pages for greasy hands and keep the full file digital for quick searching.

Safety Note

Always de-energize electrical circuits and relieve hydraulic pressure before disconnecting or testing any components.
