Notes from the research
- Two burr-clean regimes, both first-party: a light clean every couple of weeks (care article) and a deep clean every 3-6 months (manual; the article says 'every few months').
- Burr life is a floor (in excess of 750 kg), not a replacement recommendation.
- No seal or gasket guidance.
