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.
