What the specifications mean
The wheeled MP21 undercarriage and K9 front define this reference. A K10 front or crawler machine needs separately identified geometry.
Transport dimensions depend on the folded front, lowered cab and stowed outriggers. Tool choice can change the envelope and handling limits, so confirm the installed grapple or other work tool.

A brochure configuration is not an individual marketplace machine. Serial/PIN and build information are required for exact verification.
Used 818 M E-Series inspection priorities
- Inspect boom and stick joints, tool and rotator, slew components and structural repair history.
- Check cab-elevation equipment, outriggers, tires and hydraulic lines using the manufacturer’s inspection procedure.
- Verify the front and tool configuration and the applicable load information before a handling demonstration.
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
- Include tool, rotator and front-linkage wear and specialist hydraulic repairs in the estimate.
- Plan the standing area, material flow and support equipment; maximum reach does not establish capacity at a chosen handling point.

- Electric or diesel
- Cab elevation
- Grapple or magnet
A model specification does not establish compatibility with a particular attachment or option.
