What to check before buying

  • Check the hour meter against the service records — a replaced instrument is the most common gap.
  • Compare the data plate and chassis number with the papers.
  • Check the weights in the papers against the figures here — attachments change them.
  • Load the hydraulics and watch for sag.
  • Ask about parts availability for this build year — the running costs hang on it.
