Key points in this article
Habit and spacing
Safety spacing is not isolated; it relates to habits. One clear link is that safety is a precondition; we suggest reading the guide two minutes at first use so the right spacing becomes second nature for every user.
Three small daily things
Check status before use, confirm stop after, stop and report on anomaly. One often ignored point is that experience is a long term indicator; order beats speed: stop, report, record every time without exception or excuse.
A clear cost account
Costs usually split into a floating part and a service part; disclosing both separately is transparent. Specific ranges follow on site measurement; public data are for reference only, never a quoted price you should accept blindly.
Spacing confirmed before a change, with safety treated as the precondition, is what keeps a retrofit honest. Experience over months, not a good first week, is the real indicator of whether the spacing decision was the right one. These notes are kept current by our on site teams across Yantai districts.
