Direct answer: A product-manual, warning-label, and language-version page cannot be one PDF download link. It should state what the manual covers, which models/versions it applies to, where warning labels go, what languages are available, how versions are controlled, how old versions are withdrawn, how custom/OEM versions are handled, whether electronic versions/QR codes replace paper, and what must not be published. Otherwise, when a customer or auditor asks "which version is this manual, is the warning label in Chinese, what language for export, can the old version still be used," the answer is a filing-cabinet search.
This guide is for technical documentation, quality, production, export, legal, and website teams at manufacturers in Changzhou and nearby industrial areas. It explains how to build and accept a product-manual, warning-label, and language-version page. Information is current to 2026-11-02. It is a review of public regulations, standards, and project practice, not product-safety, standardisation, translation, or legal advice; specific marking content, warnings, language requirements, and version control depend on product standards, contracts, destination-country rules, and the company's document-control procedure.
Product marking must be truthful: conformity certificate, Chinese product name/manufacturer name and address, specification/grade/main components, production date/safe-use period, and warning signs or Chinese warning statements—missing any one can be a hard failure. A manual is not "an introduction for readers"; it is part of the product: it must match the physical unit, nameplate, packaging, labels, contract, and drawing revision. Version control matters more than length: withdraw old versions, keep distribution records, number custom versions separately—do not use one PDF for ten years.
How does the manual page relate to technical-data, material-compliance, packaging, and after-sales pages?
The technical-data page answers "who gets drawings/parameters and how"; the material-compliance page answers "does it meet RoHS/REACH"; the packaging page answers "how it is packed, marked, and shipped"; the after-sales page answers "how it is repaired"; the manual page answers "how it is installed, used, maintained, what warnings apply, which version, which language." A manual is a technical document delivered with the product; technical data is requested under permissions. They can share a download centre but are not the same.
The common break is: the site has one "manual download" with no model or version; parameters contradict the nameplate; warning labels are English-only with no Chinese; export products ship with Chinese manuals; an old manual stays online after revision; an OEM customer changes logo/model but the manual does not follow; a QR code points to an expired PDF. A page that states content, language, version, distribution, and boundaries gives customer audits and after-sales something to check.
| Page/entry | Answers | Audience | Cannot replace |
|---|---|---|---|
| Manual page | Content, model, version, language, distribution | Customer, after-sales, engineering | The paper manual in the box |
| Technical data | Drawings, parameters, request and permissions | Customer, engineering | Product manual |
| Material compliance | RoHS/REACH substances and reports | Customer, quality | Use and warning instructions |
| Packaging page | Packing, marks, transport, storage | Logistics, customer | Manual content |
| After-sales page | Repair, spares, service | Customer, service | Installation/use instructions |
This page map is editorial; marking requirements are in Article 27 of the Product Quality Law.
What should a manual contain?
Organise as "product information—use and limits—installation—operation—maintenance—troubleshooting—safety warnings—annexes": product name/model/version, manufacturer and contact, main technical parameters, scope of application and prohibited uses, installation conditions and steps, operating procedure, maintenance intervals, common faults and handling, safety warnings and PPE, supplied accessories/options, and warranty/after-sales. Content must match the physical unit, nameplate, drawings, and contract; do not hide key information behind "see accompanying documents."
General requirements for industrial manuals are accuracy, completeness, conciseness, comprehensibility, and consistency with the actual product; safety content must stand out, not be buried in an annex. Product-specific standards (electrical, machinery, medical, pressure equipment) take precedence. The page can provide a "manual contents/element checklist," but should not publish full text containing customer-specific processes or security details.
| Module | What to state | Evidence | Common gap |
|---|---|---|---|
| Product info | Name, model, version, manufacturer, contact | Nameplate/manual | Model mismatch |
| Use/limits | Application, prohibited uses, environment | Technical agreement | Too broad |
| Installation | Conditions, steps, checks, commissioning | Installation drawing | Steps missing |
| Operation | Procedure, parameters, interlocks, shutdown | Operating procedure | Mismatch with unit |
| Maintenance | Intervals, items, lubrication, wear parts | Service table | "Regular" only |
| Faults | Symptom, cause, handling, repair contact | Fault table | No handling |
| Safety | Warnings, PPE, emergency stop, emergency response | Risk register | Buried in annex |
These elements are editorial; general requirements are in GB/T 9969-2008 (current version per the standards platform).
What must product marking and warning labels state?
Article 27 of the Product Quality Law requires truthful marking and: a product quality conformity certificate; the product name, manufacturer name, and address in Chinese; specification, grade, and main components in Chinese where required by product characteristics and use; production date and safe-use period or expiry date in a prominent place for time-limited products; and warning signs or Chinese warning statements for products that may damage themselves or endanger personal/property safety if misused. Hazardous goods and special-requirement products must also meet Article 28 on packaging, warning signs or Chinese warning statements, and storage/transport precautions.
A warning label is not "a triangle sticker": state the hazard type, consequence, avoidance method, and protection requirement; place it prominently, durably, and firmly; Chinese must not be missing in multilingual versions. Label content must match the manual and risk register; export products must also meet destination/customer requirements (e.g., CE directives, OSHA/ANSI), not just a Chinese-to-English translation. The page can show label samples/locations, but must not publish security weaknesses or customer-specific information.
| Marking item | What to state | Basis | Common gap |
|---|---|---|---|
| Conformity | Inspection certificate/mark | Art. 27 | Missing |
| Name/manufacturer | In Chinese | Same | English only |
| Spec/components | Specification, grade, main components | Same | Not marked |
| Dates | Production date, safe-use/expiry date | Same | Not prominent |
| Warnings | Warning sign or Chinese warning statement | Same | Icon only |
| Storage/transport | Hazardous/special packaging warnings and precautions | Art. 28 | Not stated |
Marking and packaging warnings are in Articles 27 and 28 of the Product Quality Law.
What packaging warnings apply to hazardous and special-requirement products?
Article 28 requires that fragile, flammable, explosive, toxic, corrosive, radioactive, and similar hazardous goods, and products with special requirements such as "do not turn over during storage and transport," have packaging quality that meets the corresponding requirements, with warning signs or Chinese warning statements under relevant state rules, and storage/transport precautions. In other words, besides the product label, the outer packaging needs corresponding warnings—not just "handle with care" in the manual.
Packaging warnings must match the transport mode and hazard: orientation, stacking, moisture, shock, temperature, hazard class, emergency handling; exports must also meet destination/transport rules (e.g., dangerous-goods packaging and labels). Keep packaging drawings, label positions, and language versions on file; customer-specific packaging must not omit warnings. The page can show a "packaging warning illustration," but not security arrangements or customer-specific packaging designs.
| Item | What to state | Basis | Common gap |
|---|---|---|---|
| Hazard | Flammable/explosive/toxic/corrosive/radioactive | Art. 28 | Not marked |
| Packaging quality | Matches hazard and transport mode | Same | Improper packing |
| Warning sign | Graphic sign + Chinese statement | Same | Icon only |
| Storage/transport | Orientation, stacking, moisture, shock, temperature | Same | Not stated |
| Export | Destination/transport rules | Contract/rules | Domestic labels only |
| Records | Packaging drawing, label position, language | Project file | No record |
Packaging warnings are in Article 28 of the Product Quality Law; dangerous-goods transport has separate rules.
How should language versions be set and kept consistent?
Domestic products need Chinese marking; export products follow the contract for technical requirements, but destination/customer rules may require the local language (English, German, French, Spanish, etc.), and safety warnings often require the destination's official language. Multilingual versions must follow one "source version," with consistent terminology, models, parameters, and warnings; do not write a different text per language or use machine translation without review. State which languages are available, which version governs, and who translates/reviews.
The most common failure is "Chinese updated, English not": parameters changed, warnings revised, models added, but other languages remain old. The right approach is one version number and release date per language, with a "source → translation → review → release" flow; customer-specific languages get a separate number. The page can provide a "language matrix" (model × language × version) so customers see whether their language exists.
| Item | What to state | Basis | Common gap |
|---|---|---|---|
| Chinese | Chinese marking/manual for domestic sales | Art. 27 | Missing |
| Export language | Per contract/destination | Standardization Law Art. 26 | Chinese only |
| Terminology | Glossary, models, parameters, warnings consistent | Glossary | Inconsistent |
| Translation/review | Who translates, reviews, approves | Process record | Machine output used |
| Version match | Same version/date across languages | Version table | Chinese only updated |
| Custom language | Separate number for customer-specific | Project file | Generic reused |
Language requirements are in Article 27 of the Product Quality Law and Article 26 of the Standardization Law; destination rules follow local law.
How should versions and revisions be controlled?
Each manual needs a unique document number, version, release date, and revision record (what changed, why, who approved); the numbering rule must be fixed (A/B/C or 1.0/2.0), not "final/final-2/really-final." Revisions are signed by engineering, quality, legal/export; after release, the old version is withdrawn, collected, or marked "obsolete," and the electronic version is removed or replaced. Customer-specific versions get separate numbers, never mixed with the generic version.
Version control is about traceability: which manual goes with that machine; which drawing/technical agreement the parameters match; and, in a complaint or accident, which version was distributed. The page can provide a "version record/effective date," but should not publish customer-specific revision records. Old versions are not "kept for backup"—they are explicitly obsolete, or the floor may use the wrong one.
| Element | What to state | Evidence | Common gap |
|---|---|---|---|
| Number | Document no., model, language | Header | No number |
| Version | Rule, current version, effective date | Version table | "Final" |
| Revision | What, why, who approved | Revision page | No record |
| Sign-off | Engineering/quality/legal/export | Approval sheet | One person |
| Obsolete | Withdraw, collect, remove | Obsolete record | Still circulating |
| Custom | Separate number, customer confirmation | Project file | Generic reused |
Version control is editorial; document-control requirements follow the quality system and contract.
How should manuals be distributed, downloaded, and withdrawn?
Separate channels: paper/electronic in the box, website download, customer portal, and internal use. Check the packing list for in-box documents; verify model/version/language on the website; apply permissions in the portal; use controlled documents internally. Distribution records must show who received which version and when; customer-specific/project documents need sign-off. Old versions need collection records and electronic removal or replacement.
The biggest risk of "one PDF on the website" is version loss: a customer downloads an old version and follows it, or the PDF is forwarded externally. The download page should offer only the currently effective version, with version/date/applicability; historical versions, if retained, must be marked "obsolete, for traceability only." QR codes should point to a controlled page, not a cloud-drive link that can be swapped.
| Channel | What to do | Evidence | Common gap |
|---|---|---|---|
| In the box | Check against packing list; correct language | Packing list | Missing/wrong |
| Website | Model/version/language selectable; current only | Download record | Old version online |
| Portal | Permissions, version, notification | System record | No access control |
| Internal | Controlled copy, loan register | Controlled list | Free copying |
| Custom/project | Sign-off, customer confirmation | Receipt | No confirmation |
| Withdrawal | Obsolete, remove, replace | Withdrawal record | Not withdrawn |
Distribution and withdrawal are editorial; specifics follow the document-control procedure and customer requirements.
How should electronic manuals, QR codes, and online help be used?
Electronic manuals can supplement but do not automatically replace paper/in-box documents: check the contract, destination rules, and customer requirements; for safety-critical instructions, many markets still require paper or a durable copy with the product. QR codes must point to a controlled, stable, accessible page with content matching the current version; prepare a fallback (paper/download) for no-network or scan failure. Electronic versions should allow language selection, show version/date, and preferably print.
"Scan for the manual" is not "upload a PDF to a cloud drive": links expire, versions mix, permissions disappear. Use a controlled website download page or customer portal, with the QR code as an entry only; optionally log access for traceability. For export customers, confirm whether electronic delivery is accepted; for high-risk products, keep paper.
| Method | What to do | Evidence | Common gap |
|---|---|---|---|
| Paper | In the box, correct language, durable | Packing list | Omitted |
| PDF download | Controlled page, version/date, language options | Download page | Cloud link |
| QR code | Controlled page, accessible, fallback | Scan test | Dead link |
| Online help | Version-consistent, update notice | Page record | Differs from PDF |
| Customer acceptance | Whether electronic delivery is accepted | Contract/email | Assumed |
Electronic manuals are editorial; whether they replace paper follows the contract, destination rules, and customer requirements.
How should custom/OEM and multi-model manuals be handled?
Custom/OEM needs separate management: model, logo, language, parameters, warnings, packaging, and in-box documents may differ; the manual needs a separate number, separate version, and customer confirmation—not "change the logo on the generic version." When a series manual covers multiple models, state the "applicable model list" and "differences"; safety warnings for different configurations cannot be omitted. Customer trademarks/drawings need authorisation.
The typical failure is "version drift": the customer changes requirements, sales agrees verbally, the manual does not change; or the generic version is updated and the custom version is not. Build a "document package" per custom project (contract, technical agreement, manual, labels, packaging, sign-off), owned by the project manager. The page can say "custom language/logo/model supported, subject to project confirmation," but must not promise "any customisation."
| Item | What to do | Evidence | Common gap |
|---|---|---|---|
| Model | Applicable list, differences | Model table | "Series" only |
| Logo/trademark | Authorisation, position, size | Authorisation | Unauthorised |
| Language | Customer requirement, review | Confirmation email | Machine output |
| Parameters | Match custom configuration | Technical agreement | Generic reused |
| Warnings | Do not omit for configuration differences | Risk register | Omitted |
| Document package | Contract/agreement/manual/labels/sign-off | Project file | Scattered |
Custom management is editorial; specifics follow the project contract, customer requirements, and document-control procedure.
How should documents and records be traced and retained?
The traceability chain should answer: which model/serial, which manual version, which language, and to whom/when distributed; which drawing/technical agreement the parameters match; which packaging/label revision. Retain at least: master manual and language versions, revision records, approval sheets, distribution/sign-off records, obsolete-version records, label/packaging drawings, and customer-specific confirmations. Retention follows product life, contract, regulations, and records policy—not "delete when done."
Traceability is not "files on a shared drive": use numbering rules, folder structure, permissions, and backup; customer audits or accident investigations must retrieve records within a reasonable time. Electronic files should be tamper-resistant (locked/read-only); paper should be protected from loss. Customer-specific documents with confidential information are stored separately.
| Record | Content | Retention | Common gap |
|---|---|---|---|
| Master | Manual, language versions, version | Controlled folder | Scattered |
| Revision | Revision record, sign-off, approval | Version page | No record |
| Distribution | In-box, download, portal, sign-off | Distribution record | Not findable |
| Obsolete | Collection/removal record | Obsolete list | Still circulating |
| Labels/packaging | Drawings, position, language | Project file | No drawing |
| Traceability | Machine → version → distribution | Trace table | Broken chain |
Retention is editorial; specific periods follow the contract, regulations, and records policy.
What should the page say, and what must not be published?
A public page should include: the applicable model/version/language matrix, a contents/element list, a download entry for the current version, warning-label explanation and location illustration, version/effective date, electronic/QR notes, customisation notes, and technical-support contact. Do not publish: customer-specific versions with proprietary processes/parameters, security arrangements, unauthorised trademarks, internal revision disputes, the full risk register, or employee personal information. Historical versions, if retained, must be marked "obsolete."
The page exists so customers get the right version and after-sales can find it—not to publish every technical document. Wording must be precise: "current version," "applicable models," "subject to the in-box documents"—not "final interpretation reserved" (which cannot exclude statutory liability). The download page should filter by model/language to prevent wrong downloads.
| Module | What to write | Evidence/asset | Common gap |
|---|---|---|---|
| Matrix | Model × language × version | Version table | One PDF only |
| Contents | Installation, operation, maintenance, faults, safety | Manual | No contents |
| Download | Current version, version/date | Download page | Old online |
| Labels | Warning types, location, language | Label image | No illustration |
| Electronic | QR, controlled page, fallback | Scan test | Cloud link |
| Custom | Options, project confirmation | Process | Verbal promise |
| Boundaries/links | No customer-specific/security data; technical/after-sales reachable | Access control | Over-disclosure |
These modules are editorial; public scope, customer data, and wording follow confidentiality and legal advice.
Go-live acceptance checklist
Ten checks: manual content, marking and warnings, hazardous storage/transport, language versions, version control, distribution and withdrawal, electronic/QR, custom management, traceability, and public boundaries plus links. Each needs an owner, evidence, and review date. The pass condition is not "the page has a PDF," but that a customer can find the current version by model/language, labels match the manual, old versions are clearly obsolete, and complaints/accidents trace to the distributed version.
Before go-live, run one real machine through: nameplate → labels → manual version → language → packing list → website download → QR code → customer sign-off → obsolete old version. Any step that fails is a gap in the page or document control.
| Check | Pass condition | Evidence | If it fails |
|---|---|---|---|
| Content | Product info, installation, operation, maintenance, faults, safety | Manual | Add content |
| Marking/warnings | Certificate, Chinese name/address, spec, dates, warnings | Nameplate/label | Add marking |
| Hazardous storage | Packaging warning, Chinese statement, precautions | Packaging image | Add warnings |
| Language | Chinese; export per contract/destination; terminology consistent | Language matrix | Translate |
| Version | Number, version, date, revision, sign-off | Version page | Add version |
| Distribution/withdrawal | In-box, download, portal, obsolete withdrawal | Records | Add records |
| Electronic | Controlled page, accessible, fallback, version match | Scan test | Change link |
| Custom | Separate number, authorisation, customer confirmation | Project file | Add authorisation |
| Traceability | Machine → version → distribution record | Trace record | Build chain |
| Boundaries/links | No customer-specific/security data; technical/after-sales reachable | Page test | Remove/fix |
This checklist is editorial; specific marking, warnings, language, and versions follow the law, standards, contract, and document-control procedure.
Who should read this, who should not, and what decisions does it support?
It suits manufacturers in Changzhou and nearby areas with physical products, export business, customer audits, or installation/after-sales requirements—especially equipment, electrical, machinery, medical devices, chemical materials, and industrial consumer goods; it also suits buyers checking supplier in-box documents. It does not suit pure software/services, products without marking requirements, or teams wanting one page to replace product standards/legal advice.
Read it if you are in technical documentation, quality, production, export, legal, after-sales, or a website vendor; you are building a manual download page, organising warning labels, doing multilingual versions, or preparing for a customer audit; or you need to answer "what goes in the manual, where do labels go, what language for export, how are versions controlled, what about old versions, can electronic replace paper." Skip it if one PDF serves ten years, old versions are never withdrawn, machine translation counts as review, or you want a page with "final interpretation reserved." It supports self-review of content, marking, language, versions, distribution, electronic copies, customisation, and traceability.

FAQ
Must the manual be in Chinese?
Domestic product marking must show the product name, manufacturer name, and address in Chinese; specification, grade, and main components must be in Chinese where required; products that may endanger safety if misused need warning signs or Chinese warning statements. The manual, as a delivered technical document, should use a language the customer/market understands; exports follow the contract and destination rules.
What language should an export manual use?
Export technical requirements follow the contract, but destination rules/customers may require the local language, and safety warnings often require the destination's official language. Use one source version for translation and review, keeping models, parameters, and warnings consistent; do not send machine-translated Chinese-to-English without review.
What should a warning label state?
State the hazard type, possible consequence, avoidance method, and protection requirement; place it prominently and durably; Chinese warning statements must not be missing. Hazardous/special-requirement packaging must also meet storage/transport requirements and state precautions. Label content must match the manual and risk register.
What happens to old versions after a revision?
Old versions must be explicitly obsoleted: collect/destroy paper or mark it obsolete, remove or replace electronic links, and keep distribution records. The website keeps only the current effective version; if history is retained, mark it "obsolete, for traceability only" to prevent customers from following the old version.
Can an electronic manual or QR code replace paper?
Depends on the contract, destination rules, and customer requirements. Electronic versions can supplement, but for safety-critical instructions many markets still require paper or a durable copy with the product; QR codes must point to a controlled, stable page with a fallback for no-network or scan failure.
Can the website publish the full manual?
It can publish the generic/current version, but assess customer-specific processes, parameters, and security information; custom or customer-specific versions should not be public. The page should provide a "model/language/version matrix + current download," with historical versions marked obsolete.
One-sentence takeaway
A Changzhou manufacturer's product-manual, warning-label, and language-version page should not be "a PDF." It should turn content elements, marking and warnings, hazardous packaging, language matrix, version control, distribution and withdrawal, electronic copies, customisation, and traceability into a verifiable checklist—so a customer can find the current version by model/language.
Method and limitations
This is a review of public regulations, standards, and project practice, not a certification or legal opinion on any company's product, manual, labels, translation, or document control. No undisclosed customer manuals, drawings, or complaint data were used. Content elements, language matrix, checklists, and the acceptance checklist are editorial suggestions, not product-safety, standardisation, translation, or legal conclusions. Specific marking, warnings, language, versions, and distribution depend on product standards, contracts, destination rules, and the company's document-control procedure.
