A brochure configuration is not an individual marketplace machine. Serial/PIN and build information are required for exact verification.

Used DX300LC-7 inspection priorities

  • Measure the complete undercarriage and check travel and final drives under load.
  • Cycle boom, arm, bucket and swing while checking cylinders, pins and slew movement.
  • Confirm coupler, auxiliary circuits and installed technology from the actual machine.
  • Match the DX300LC-7 model plate, fitted equipment and serial/PIN to the cited generation and configuration.

Configuration-aware inspection: these checks are triggered by machine category, installed configuration and technology package. Brochure-listed technology must be physically present, active, licensed and calibrated on the used machine.

Hours, condition and ownership cost

Hours are context, not a condition grade. Duty cycle, idle time, maintenance evidence, wear-system measurements, structural repairs and installed technology should be evaluated together.

Cost drivers to model

  • Undercarriage, pins, cylinders, pumps and final drives need evidence-based reserves.
  • Attachment duty changes fuel, cooling and hydraulic wear.
  • Transport exposure changes with shoes, front, counterweight and guarding.

Compatibility graph

Attachment considerations

Relationships below identify relevant classes only unless a stronger evidence state is shown. They never assert exact used-attachment fitment.

Excavator buckets and couplers

Verify pin or coupler geometry, attachment weight, linkage.

relevant attachment class

Hydraulic breakers and processors

Verify carrier class, flow, pressure, return and case drain.

Open attachment research

Before confirming fitment

  • generation and machine configuration
  • mounting interface, coupler or pin geometry
  • hydraulic flow, pressure, return and case drain
  • attachment weight and machine capacity limits
  • electrical controls or required machine options
