The archive groups concrete demolition saw features under power or motor, diamond blade, and dust management. Those headings are retained as document-control domains. They do not establish a rating relationship, blade choice, exposure-control method, cutting capability, or result.
From feature language to controlled evidence
A technical heading becomes reviewable only when it is tied to an exact model, current document revision, declared scope, and responsible issuer. Units such as HP, W, and RPM appear in the archive without model-bound values; their presence alone supports no comparison or selection conclusion.
Three feature domains
Power and motor documentation
The archive mentions ratings, torque, rotational speed, and motor cooling. This ledger records those as manual and datasheet fields only. It states no relationship between a larger value and capability, and it gives no operating or selection direction.
Blade documentation
Diamond crystals, segments, and construction terms appear in the saved copy. A current claim would require exact blade identity, manufacturer documentation, machine binding, and bounded evidence. This article supplies no segment, construction, depth, finish, heat, durability, or blade-selection conclusion.
Dust-control documentation
Collection, external vacuum, and water-suppression terms are archived topics, not a control plan. Evidence would have to identify the exact machine and project-specific exposure-control authority. No device sufficiency, connection arrangement, procedure, visibility result, or health outcome is stated.
Document-control ledger
| Evidence item | Identity fields to retain | Conclusion excluded here |
|---|---|---|
| Model datasheet | Exact model, issuer, revision, and declared values | No rating-to-capability relationship or product comparison |
| Current manual | Model binding, revision, declared feature scope, and limitations | No operation, blade selection, or cutting instruction |
| Blade record | Exact blade identity and the document source attached to that identity | No depth, smoothness, durability, heat, or continuous-use result |
| Site control record | Named project, responsible exposure-control authority, and approved plan reference | No generic dust-control procedure or sufficiency assurance |
What the archived headings can support
They can support a document request organized around three feature domains. They cannot support a technical recommendation or an outcome claim. Keeping model evidence, blade evidence, and site-control evidence in separate ledger rows prevents one broad heading from being treated as a complete system.
