Key points in this article
The one takeaway
If only one line is kept: clarify fuzzy zones early. Many do the reverse and the gap shows over time; early attention costs less than later repair and keeps the pile dependable for daily users who notice everything.
Signals to note
Some changes are not urgent yet worth logging. A useful gauge is that written terms beat oral promises; most trouble we logged came from cutting corners instead of doing the careful, documented thing properly.
Safety baseline
Do not modify or add parts yourself; stop on abnormal heat or smell; postpone outdoor charging in thunderstorms; keep children and pets away from charging areas at all times to prevent avoidable harm and damage.
Useful data is the kind you can read next month: what was checked, when, by whom, and what changed. Written terms and clear boundaries turn a pile's maintenance from folklore into a record that actually aids the next review. These notes are kept current by our on site teams across Yantai districts.
