About this site and its sources
How the English pages are built
- Technical text on English pages is the original English wording of the manufacturer's documentation (error tables, service manuals, user manuals), quoted with document and PDF page. It is not translated from Polish.
- Plain-language explanations are editorial: written from the cited facts only, without values that are not in the sources, and marked as a draft.
- Pages that only quote the source (no plain-language text yet) are marked and not indexed by search engines.
- Product lines documented only in Polish-language sources have no English pages yet.
- The Polish site is the primary edition and has more detail (safe checks, guides, discrepancies between sources).
