Terminology and manual questions
The archive behind “Essential Knowledge about Concrete Saw for Professionals” lists several saw-type and component terms. This edition treats them as non-exhaustive vocabulary and asks what product or manual evidence would be needed before any term could support a current statement.

Saw-type words found in the archive
Handheld
A saved label only. No exact model, power source, blade, application, or manual is attached.
Walk-behind
A historical category name without a documented product identity or project role.
Wall-mount
An archive term that does not establish a mounting system, configuration, or present catalog entry.
The three words are not presented as a complete classification and must not be used as a selection rule.

Questions that belong with an exact manual
Identity question
Which product name, model, revision, and dated catalog record does the terminology describe?
Document question
Which manufacturer-issued manual defines the component names and scope, and does its revision match the identified product?
Media question
Which source confirms that each retained photograph shows the same product and material context?
Claim question
Which dated record directly supports the statement being considered, rather than merely repeating a generic term?
Component vocabulary is not operating evidence
The old page names engine, handle, depth, and water-supply topics. Those words show what the previous article discussed; they do not define a configuration, setting, interface, or requirement. Without an exact product and matching manual, the vocabulary cannot support equipment use, project assignment, or a claimed result.
Generic legacy language about alignment, protective equipment, cleaning, lubrication, and replacement is outside this record and is not reproduced.

| Archive entry | What remains unknown | Document needed for a supported statement |
|---|---|---|
| Saw-type label | Exact product identity and whether the category applies | Matching dated catalog record |
| Component term | Definition, scope, and product revision | Manufacturer-issued manual for the exact model |
| Retained image | Product, material, and context shown | Traceable caption or media record |
