Updating Portuguese to Chinese Manuals: Reuse or Rebuild?

Assess Portuguese to Chinese manual updates using source revisions, existing Chinese files and change records. Compare the published XCMG machinery project.

Match Portuguese revisions to the existing Chinese manual

Before reusing an existing Chinese manual, establish which Portuguese source revision it belongs to. Identify changed and unchanged material and review the effect on terminology, figures and cross-references. A translation-memory match alone does not establish that the current instruction is unchanged.

Review status: questions to confirm

Self-created revision record, not an XCMG manual or a completed change assessment. It illustrates what to compare before deciding the scope of a new update.
  1. Establish the file lineage

    Link the existing Chinese file to the Portuguese source revision from which it was translated.

  2. Map changes beyond the sentence

    Review affected diagrams, part references and repeated terms alongside the changed passages.

  3. Agree the update scope

    Record what can be reused, what needs review or new translation, and the format of the revised handover.

For your quotation

For an existing Chinese translation update, provide the current source, earlier source and Chinese versions if available, revision notes and editable files. Confirm the actual source language and Chinese script, then agree comparison depth, update scope, review ownership, final format and deadline.

Compare a representative set before choosing the update scope

Start with the current Portuguese source, the earlier source used for the Chinese translation and the matching Chinese file. If the link between editions is uncertain, list that gap rather than assuming the old Chinese file matches the nearest available source. Include any change log and approved term list.

Choose samples from each distinct source edition, authoring period or document family. Include changed passages and material that can carry a change beyond the sentence, such as figures, model references and repeated warnings. Use the findings to scope further review; a clean sample does not establish that the complete manual is ready to release.

Assign reuse, revision or new translation by section

Reuse a section only after the agreed comparison supports it: the source edition and context match, the Chinese meaning remains suitable and affected references have been checked. A terminology pass may be enough when the wording is accurate and only approved names or terms have changed. It will not resolve a missing instruction or an incorrect relationship between a figure and the text.

Revise or translate the affected section again when the current source changes its meaning, the Chinese wording is unreliable or the usable source-to-Chinese relationship cannot be established. Record why it was selected, along with any linked sections that need checking. Compare these scoped options before agreeing effort and price; there is no fixed saving from reuse.

Separate the current handover from archive references

Ask the Chinese recipient which edition and tasks they need now. Put current-use files in the proposed handover and identify superseded or reference-only files separately. Keep archive and retention decisions with the document owner; low readership alone is not a reason to discard a file or ignore an unresolved requirement.

For each selected section, record the proposed disposition, unresolved source questions and Chinese review owner. Agree how later changes will be marked and which edited, bilingual or final-layout files will be returned. Capture approved terminology decisions so the next update can refer to the same recorded choices.

Questions

Can an old Chinese manual be reused after the Portuguese source changes?
Possibly. Compare the current Portuguese source, the source version used for the old Chinese manual and any change log. Check the effect on instructions, references and terminology before agreeing which sections can be reused, revised or translated again.
How much of the old Chinese manual should we sample?
Cover each distinct source edition or document family and include changed passages, figures and cross-references that may affect meaning. Record what the sample covers and what remains unchecked. The initial sample helps define the review scope; it is not acceptance of the entire manual.
When is a terminology pass enough?
When comparison shows that the underlying Chinese meaning is sound and the required changes are limited to approved terms or names. Check whether those changes affect figures, identifiers or references. If the source meaning or Chinese accuracy has changed, scope the affected sections for further revision or new translation.
Should superseded manuals be included in the update?
Ask the document owner which files are for current Chinese use and which are archive or reference material. List them separately before quotation. Do not treat low readership as proof that a file has no remaining use or retention requirement.
