How do you translate a machinery instruction manual into another language without changing actions that keep people safe? Translation of industrial machinery handbooks involves warning statements, setup sequences, operating limits, maintenance schedules, troubleshooting instructions and equipment-specific diagrams. A missing negation, altered unit or mistaken reference to a control can change the action a technician takes. This guide explains how to translate machinery instructions accurately and review their practical meaning before release.
Readers searching for ISO 20607:2019 machinery manual translation, residual risk warning translation, industrial equipment operating instructions, machine maintenance manual localisation or multilingual machine setup procedures need a document that works beside the equipment. They may be introducing a machine into a new market, updating a supplier’s handbook or preparing instructions for multilingual maintenance personnel. The correct result is not elegant prose alone. Operators must understand the applicable configuration, safe prerequisites, limits and authorised steps.
ISO 20607:2019 is titled Safety of machinery — Instruction handbook — General drafting principles. Its official catalogue describes preparation of safety-related parts of the instruction handbook and communication of residual risks across stages of the machine’s life. The 2019 edition was published at the time checked, while a revision was under development. This independent guide uses fictional cases and original explanations, not reproduced copyrighted standard clauses, and it does not replace machine-specific approved instructions, risk assessments, safety procedures, engineering advice or applicable law.
Quick answer: translate the safe action, not just the technical term
The starting point is the authorised machine-specific manual and its associated risk and configuration information. Identify what the operator or technician must know, which action is permitted, and which prerequisites or limits make the instruction true. Protect step order, model identity, negations, numerical data, warning severity and diagrams. If the original source is incomplete or contradictory, that is a problem for its technical owner rather than an invitation for the translator to invent engineering details.
A machine instruction handbook is a working artifact. It may be read next to a control panel, in poor lighting, with gloves or under time pressure. A technically correct translation that refers to the wrong drawing or uses a different name for the same switch can still be unusable. Safety review should include final format, context and comprehension, not only proofread text.
Ten foundations for understanding the engineering language
1. One machine, one configuration
A manual is linked to a model, serial range, attachment set and revision, not simply a generic product class. Consider this example: A handbook for an earlier machine guard is supplied with a new configuration that has a different interlock. This matters because machine instructions can influence real-world actions rather than merely convey background information. The target-language reader must be able to identify the same component, condition and action described in the approved original.
Review method: Identify exact equipment and approved revision before using instructions. Compare the source and translated instruction together with the current equipment drawing. Do not solve an unknown safety condition by selecting whichever translation sounds more natural. Record the ambiguity, ask a competent technical authority, and carry the approved decision to every related label, diagram and document.
2. Commands versus descriptions
Statements about how a component functions are different from commands to act upon it. Consider this example: A translated description of emergency stop behavior becomes an instruction to use it at the end of every cycle. This matters because machine instructions can influence real-world actions rather than merely convey background information. The target-language reader must be able to identify the same component, condition and action described in the approved original.
Review method: Check the function of each verb in its paragraph. Compare the source and translated instruction together with the current equipment drawing. Do not solve an unknown safety condition by selecting whichever translation sounds more natural. Record the ambiguity, ask a competent technical authority, and carry the approved decision to every related label, diagram and document.
3. Residual risk
Hazards remaining after engineering controls must be described with their actual conditions and consequences. Consider this example: A detailed warning about a hot housing after shutdown becomes a generic phrase about heat. This matters because machine instructions can influence real-world actions rather than merely convey background information. The target-language reader must be able to identify the same component, condition and action described in the approved original.
Review method: Retain the specific hazard, condition, potential harm and prescribed action. Compare the source and translated instruction together with the current equipment drawing. Do not solve an unknown safety condition by selecting whichever translation sounds more natural. Record the ambiguity, ask a competent technical authority, and carry the approved decision to every related label, diagram and document.
4. Prerequisites and sequence
The order of isolation, inspection, adjustment and restart may be essential to a procedure. Consider this example: A target-language editor relocates a prerequisite to the end to make the paragraph more elegant. This matters because machine instructions can influence real-world actions rather than merely convey background information. The target-language reader must be able to identify the same component, condition and action described in the approved original.
Review method: Preserve procedural dependencies and step references. Compare the source and translated instruction together with the current equipment drawing. Do not solve an unknown safety condition by selecting whichever translation sounds more natural. Record the ambiguity, ask a competent technical authority, and carry the approved decision to every related label, diagram and document.
5. Units and limits
Numbers, torque values, electrical ratings and safe working limits are controlled technical information. Consider this example: A conversion changes precision or drops the maximum qualifier next to a load value. This matters because machine instructions can influence real-world actions rather than merely convey background information. The target-language reader must be able to identify the same component, condition and action described in the approved original.
Review method: Protect source data and obtain engineering approval for technical changes. Compare the source and translated instruction together with the current equipment drawing. Do not solve an unknown safety condition by selecting whichever translation sounds more natural. Record the ambiguity, ask a competent technical authority, and carry the approved decision to every related label, diagram and document.
6. Drawings and callouts
A step may be understandable only when the label, arrow and diagram match the text. Consider this example: A translated page refers to Figure 7 after reflow moves the relevant drawing to Figure 8. This matters because machine instructions can influence real-world actions rather than merely convey background information. The target-language reader must be able to identify the same component, condition and action described in the approved original.
Review method: Check the final rendered document and equipment mapping. Compare the source and translated instruction together with the current equipment drawing. Do not solve an unknown safety condition by selecting whichever translation sounds more natural. Record the ambiguity, ask a competent technical authority, and carry the approved decision to every related label, diagram and document.
7. Permissions and competency
Operators, technicians, electricians and authorised service staff may have different allowed tasks. Consider this example: A restricted electrical procedure is rewritten as a general operator tip. This matters because machine instructions can influence real-world actions rather than merely convey background information. The target-language reader must be able to identify the same component, condition and action described in the approved original.
Review method: Retain competence boundaries and approval requirements. Compare the source and translated instruction together with the current equipment drawing. Do not solve an unknown safety condition by selecting whichever translation sounds more natural. Record the ambiguity, ask a competent technical authority, and carry the approved decision to every related label, diagram and document.
8. Negative conditions
Never, only, unless, before and after can carry the highest consequence in a short instruction. Consider this example: A missing do not converts a prohibited action into a positive command. This matters because machine instructions can influence real-world actions rather than merely convey background information. The target-language reader must be able to identify the same component, condition and action described in the approved original.
Review method: Review logical operators and negation independently. Compare the source and translated instruction together with the current equipment drawing. Do not solve an unknown safety condition by selecting whichever translation sounds more natural. Record the ambiguity, ask a competent technical authority, and carry the approved decision to every related label, diagram and document.
9. Operating states
A machine being stopped, de-energised, depressurised and mechanically secured can be four different conditions. Consider this example: The translator uses one word for stopped and isolated and blurs an essential distinction. This matters because machine instructions can influence real-world actions rather than merely convey background information. The target-language reader must be able to identify the same component, condition and action described in the approved original.
Review method: Use the manufacturer’s state terminology and verify each step. Compare the source and translated instruction together with the current equipment drawing. Do not solve an unknown safety condition by selecting whichever translation sounds more natural. Record the ambiguity, ask a competent technical authority, and carry the approved decision to every related label, diagram and document.
10. Revision control
Corrections and safety bulletins must be reflected in every relevant language edition. Consider this example: A translated manual remains accessible after the source language was corrected for a known hazard. This matters because machine instructions can influence real-world actions rather than merely convey background information. The target-language reader must be able to identify the same component, condition and action described in the approved original.
Review method: Track changes by affected equipment and replace superseded releases. Compare the source and translated instruction together with the current equipment drawing. Do not solve an unknown safety condition by selecting whichever translation sounds more natural. Record the ambiguity, ask a competent technical authority, and carry the approved decision to every related label, diagram and document.
Twenty-four machine-manual translation decisions
The following examples are fictional, and none should be treated as instructions to operate or service a particular machine. Their purpose is to reveal how translation can change the meaning of a warning, requirement, numeric specification or machine state. Always use approved manufacturer and workplace safety procedures for actual equipment.
1. Before first operation
The source requires pre-use checks before a new operator starts a machine. The translator should first identify the machine configuration, the authorised instruction and the prerequisite states that give the sentence meaning. Without that context, a familiar technical word may point to a different component or operating condition.
The problematic interpretation is: The translated heading suggests these checks can be done after the first production cycle. A fluent reader may assume the words are reliable and act without consulting the source language. The risk is therefore not an awkward sentence alone; it is that the intended boundaries of a task, warning or numerical limit have been moved.
A defensible correction is: Preserve the temporal prerequisite and make the checklist clearly findable before start. Check the complete page, associated diagram, warning level, cross-reference and final layout. The reviewer should be able to explain what condition must be true before the instruction applies, what it authorises and what it expressly excludes. If those answers differ between languages, release is not ready.
For training, ask a qualified reviewer to mark the subject, verb, object, condition and exception in each language. Compare those elements on a controlled copy without performing a dangerous action. Have the manufacturer or authorised engineer resolve any uncertainty, and document which version and machine configuration the answer covers. This is a safe comprehension exercise, not permission to experiment on moving equipment.
2. Energy isolation
A maintenance instruction refers to the approved equipment-specific isolation procedure and other stored energy hazards. The translator should first identify the machine configuration, the authorised instruction and the prerequisite states that give the sentence meaning. Without that context, a familiar technical word may point to a different component or operating condition.
The problematic interpretation is: The target text reduces the instruction to turning off a switch. A fluent reader may assume the words are reliable and act without consulting the source language. The risk is therefore not an awkward sentence alone; it is that the intended boundaries of a task, warning or numerical limit have been moved.
A defensible correction is: Translate the actual approved instruction and have competent safety personnel check completeness. Check the complete page, associated diagram, warning level, cross-reference and final layout. The reviewer should be able to explain what condition must be true before the instruction applies, what it authorises and what it expressly excludes. If those answers differ between languages, release is not ready.

3. Stored pressure
A pneumatic system may remain pressurised after the motor stops. The translator should first identify the machine configuration, the authorised instruction and the prerequisite states that give the sentence meaning. Without that context, a familiar technical word may point to a different component or operating condition.
The problematic interpretation is: The translation treats stopped movement as proof that pressure has been released. A fluent reader may assume the words are reliable and act without consulting the source language. The risk is therefore not an awkward sentence alone; it is that the intended boundaries of a task, warning or numerical limit have been moved.
A defensible correction is: Keep pressure status and verification separate from motor status. Check the complete page, associated diagram, warning level, cross-reference and final layout. The reviewer should be able to explain what condition must be true before the instruction applies, what it authorises and what it expressly excludes.

The translator should first identify the machine configuration, the authorised instruction and the prerequisite states that give the sentence meaning. Without that context, a familiar technical word may point to a different component or operating condition.
The problematic interpretation is: The target uses a mild word for warmth and omits the post-shutdown condition. A fluent reader may assume the words are reliable and act without consulting the source language. The risk is therefore not an awkward sentence alone; it is that the intended boundaries of a task, warning or numerical limit have been moved.
A defensible correction is: Retain the burn hazard, affected component and specified conditions. Check the complete page, associated diagram, warning level, cross-reference and final layout. The reviewer should be able to explain what condition must be true before the instruction applies, what it authorises and what it expressly excludes.

The translator should first identify the machine configuration, the authorised instruction and the prerequisite states that give the sentence meaning. Without that context, a familiar technical word may point to a different component or operating condition.
The problematic interpretation is: The translation drops not and turns the prohibition into a command. A fluent reader may assume the words are reliable and act without consulting the source language. The risk is therefore not an awkward sentence alone; it is that the intended boundaries of a task, warning or numerical limit have been moved.
A defensible correction is: Perform an independent negation check with the final printed document. Check the complete page, associated diagram, warning level, cross-reference and final layout.

6. Interlocked guard
A specific machine configuration has a particular guarded access door and control arrangement. The translator should first identify the machine configuration, the authorised instruction and the prerequisite states that give the sentence meaning. Without that context, a familiar technical word may point to a different component or operating condition.
The problematic interpretation is: The target promises that opening any door stops every motion instantly. A fluent reader may assume the words are reliable and act without consulting the source language. The risk is therefore not an awkward sentence alone; it is that the intended boundaries of a task, warning or numerical limit have been moved.
A defensible correction is: Describe the protective function only as documented for this exact machine. Check the complete page, associated diagram, warning level, cross-reference and final layout.

21. Emergency incident
A machine-related warning describes actions that reduce exposure during an incident. The translator should first identify the machine configuration, the authorised instruction and the prerequisite states that give the sentence meaning. Without that context, a familiar technical word may point to a different component or operating condition.
The problematic interpretation is: The translation invents a universal evacuation distance not supplied by the manufacturer. A fluent reader may assume the words are reliable and act without consulting the source language. The risk is therefore not an awkward sentence alone; it is that the intended boundaries of a task, warning or numerical limit have been moved.
A defensible correction is: Retain verified source directions and coordinate with site emergency procedures. Check the complete page, associated diagram, warning level, cross-reference and final layout. The reviewer should be able to explain what condition must be true before the instruction applies, what it authorises and what it expressly excludes. If those answers differ between languages, release is not ready.
For training, ask a qualified reviewer to mark the subject, verb, object, condition and exception in each language. Compare those elements on a controlled copy without performing a dangerous action. Have the manufacturer or authorised engineer resolve any uncertainty, and document which version and machine configuration the answer covers. This is a safe comprehension exercise, not permission to experiment on moving equipment.
22. Decommissioning
A handbook describes safe removal from service and related energy or disposal considerations. The translator should first identify the machine configuration, the authorised instruction and the prerequisite states that give the sentence meaning. Without that context, a familiar technical word may point to a different component or operating condition.
The problematic interpretation is: The target reduces the process to switching off and throwing the machine away. A fluent reader may assume the words are reliable and act without consulting the source language. The risk is therefore not an awkward sentence alone; it is that the intended boundaries of a task, warning or numerical limit have been moved.
A defensible correction is: Keep the approved life-cycle phases and competence requirements. Check the complete page, associated diagram, warning level, cross-reference and final layout. The reviewer should be able to explain what condition must be true before the instruction applies, what it authorises and what it expressly excludes. If those answers differ between languages, release is not ready.
For training, ask a qualified reviewer to mark the subject, verb, object, condition and exception in each language. Compare those elements on a controlled copy without performing a dangerous action. Have the manufacturer or authorised engineer resolve any uncertainty, and document which version and machine configuration the answer covers. This is a safe comprehension exercise, not permission to experiment on moving equipment.
23. Safety bulletin
A correction applies to an identified group of machines and supersedes a previous instruction. The translator should first identify the machine configuration, the authorised instruction and the prerequisite states that give the sentence meaning. Without that context, a familiar technical word may point to a different component or operating condition.
The problematic interpretation is: The translation republishes the old text without the correction or affected serial range. A fluent reader may assume the words are reliable and act without consulting the source language. The risk is therefore not an awkward sentence alone; it is that the intended boundaries of a task, warning or numerical limit have been moved.
A defensible correction is: Track the bulletin, scope and withdrawn editions. Check the complete page, associated diagram, warning level, cross-reference and final layout. The reviewer should be able to explain what condition must be true before the instruction applies, what it authorises and what it expressly excludes. If those answers differ between languages, release is not ready.

Have the manufacturer or authorised engineer resolve any uncertainty, and document which version and machine configuration the answer covers. This is a safe comprehension exercise, not permission to experiment on moving equipment.
24. Replacement part
A service part is identified by exact drawing and manufacturer part number. The translator should first identify the machine configuration, the authorised instruction and the prerequisite states that give the sentence meaning. Without that context, a familiar technical word may point to a different component or operating condition.
The problematic interpretation is: The target uses a regional nickname that could refer to several incompatible components. A fluent reader may assume the words are reliable and act without consulting the source language. The risk is therefore not an awkward sentence alone; it is that the intended boundaries of a task, warning or numerical limit have been moved.
A defensible correction is: Retain controlled part numbers and verify all explanatory synonyms. Check the complete page, associated diagram, warning level, cross-reference and final layout. The reviewer should be able to explain what condition must be true before the instruction applies, what it authorises and what it expressly excludes. If those answers differ between languages, release is not ready.

The full engineering translation workflow
Stage 1: Confirm equipment
Capture model, serial range, controller revision, installed attachments and intended region of use. A completion record should identify the responsible person, revision reviewed and the evidence examined. A checklist cannot be considered effective merely because it contains signatures. Verify that the finished language version has actually been compared with the relevant equipment and that affected figures, tables, control labels and dependent procedures are in the same release set.
Stage 2: Collect source authority
Use the manufacturer’s currently approved handbook, drawings, warnings and technical bulletins. A completion record should identify the responsible person, revision reviewed and the evidence examined. A checklist cannot be considered effective merely because it contains signatures. Verify that the finished language version has actually been compared with the relevant equipment and that affected figures, tables, control labels and dependent procedures are in the same release set.
Stage 3: Classify high-risk content
Mark negation, energy states, operating limits, hazard descriptions, prerequisites and technical numbers. A completion record should identify the responsible person, revision reviewed and the evidence examined. A checklist cannot be considered effective merely because it contains signatures. Verify that the finished language version has actually been compared with the relevant equipment and that affected figures, tables, control labels and dependent procedures are in the same release set.
Stage 4: Build the terminology table
Control names of switches, components, guards, machine states and units consistently across pages. A completion record should identify the responsible person, revision reviewed and the evidence examined. A checklist cannot be considered effective merely because it contains signatures. Verify that the finished language version has actually been compared with the relevant equipment and that affected figures, tables, control labels and dependent procedures are in the same release set.
Stage 5: Translate linked media
Review drawings, interface strings, labels, photographs and instruction paragraphs as one unit. A completion record should identify the responsible person, revision reviewed and the evidence examined. A checklist cannot be considered effective merely because it contains signatures. Verify that the finished language version has actually been compared with the relevant equipment and that affected figures, tables, control labels and dependent procedures are in the same release set.
Stage 6: Technical review
Use qualified language and machine safety expertise, referring uncertainties to the manufacturer. A completion record should identify the responsible person, revision reviewed and the evidence examined. A checklist cannot be considered effective merely because it contains signatures. Verify that the finished language version has actually been compared with the relevant equipment and that affected figures, tables, control labels and dependent procedures are in the same release set.
Stage 7: Comprehension testing
Use safe simulations and supervised comprehension checks rather than hazardous live experiments. A completion record should identify the responsible person, revision reviewed and the evidence examined. A checklist cannot be considered effective merely because it contains signatures. Verify that the finished language version has actually been compared with the relevant equipment and that affected figures, tables, control labels and dependent procedures are in the same release set.
Stage 8: Release control
Synchronise PDFs, labels, service portals and correction notices across every language. A completion record should identify the responsible person, revision reviewed and the evidence examined. A checklist cannot be considered effective merely because it contains signatures. Verify that the finished language version has actually been compared with the relevant equipment and that affected figures, tables, control labels and dependent procedures are in the same release set.
A detailed quality-control check before publication
1. Match the approved machine model, serial range, configuration and source revision. Confirm the result against the source of technical authority, not a translator’s preferred practice. If a reviewer cannot verify a safety-critical point, preserve the issue for resolution before releasing the affected content. An unverified assumption should never be disguised by polished wording.
2. Identify every warning, residual hazard, condition and action in a structured risk-focused review. Confirm the result against the source of technical authority, not a translator’s preferred practice. If a reviewer cannot verify a safety-critical point, preserve the issue for resolution before releasing the affected content. An unverified assumption should never be disguised by polished wording.
3. Independently review negations, only-if clauses, limits, prerequisites and stop-work triggers. Confirm the result against the source of technical authority, not a translator’s preferred practice. If a reviewer cannot verify a safety-critical point, preserve the issue for resolution before releasing the affected content. An unverified assumption should never be disguised by polished wording.
4. Verify all units, tolerances, ratings, references and component identifiers with authorised engineering data. Confirm the result against the source of technical authority, not a translator’s preferred practice. If a reviewer cannot verify a safety-critical point, preserve the issue for resolution before releasing the affected content. An unverified assumption should never be disguised by polished wording.
5. Check illustration arrows, callout numbers, captions, table columns and interface labels after layout. Confirm the result against the source of technical authority, not a translator’s preferred practice. If a reviewer cannot verify a safety-critical point, preserve the issue for resolution before releasing the affected content. An unverified assumption should never be disguised by polished wording.
6. Keep operating, stopped, isolated, depressurised and secured as separate states where the source does. Confirm the result against the source of technical authority, not a translator’s preferred practice. If a reviewer cannot verify a safety-critical point, preserve the issue for resolution before releasing the affected content. An unverified assumption should never be disguised by polished wording.
7. Distinguish duties assigned to operators, maintenance staff and qualified electrical personnel. Confirm the result against the source of technical authority, not a translator’s preferred practice. If a reviewer cannot verify a safety-critical point, preserve the issue for resolution before releasing the affected content. An unverified assumption should never be disguised by polished wording.
8. Test navigation from the table of contents and labels to the exact instruction a user needs. Confirm the result against the source of technical authority, not a translator’s preferred practice. If a reviewer cannot verify a safety-critical point, preserve the issue for resolution before releasing the affected content. An unverified assumption should never be disguised by polished wording.
9. Record technical questions, approved corrections, sign-off and language-specific version numbers. Confirm the result against the source of technical authority, not a translator’s preferred practice. If a reviewer cannot verify a safety-critical point, preserve the issue for resolution before releasing the affected content. An unverified assumption should never be disguised by polished wording.
10. Provide a way for users to report unclear instructions and obtain current safety updates. Confirm the result against the source of technical authority, not a translator’s preferred practice. If a reviewer cannot verify a safety-critical point, preserve the issue for resolution before releasing the affected content. An unverified assumption should never be disguised by polished wording.
Four review workshops
Workshop 1: Energy isolation
Start with this fictional context: A maintenance instruction refers to the approved equipment-specific isolation procedure and other stored energy hazards. The questionable translation has this effect: The target text reduces the instruction to turning off a switch. Identify the controlling equipment condition, applicable document and the specific action that the target reader may infer. If a missing qualifier might change the instruction, make that qualifier visible in the review record.
The correction principle is: Translate the actual approved instruction and have competent safety personnel check completeness. Review source text, drawing and machine-specific approval together. Have the reviewer state in plain language what is permitted, what is forbidden and what remains uncertain. The workshop is complete only after the approved wording, corresponding technical evidence and final rendered language edition can be matched.
Workshop 2: Interlocked guard
Start with this fictional context: A specific machine configuration has a particular guarded access door and control arrangement. The questionable translation has this effect: The target promises that opening any door stops every motion instantly. Identify the controlling equipment condition, applicable document and the specific action that the target reader may infer. If a missing qualifier might change the instruction, make that qualifier visible in the review record.
The correction principle is: Describe the protective function only as documented for this exact machine. Review source text, drawing and machine-specific approval together. Have the reviewer state in plain language what is permitted, what is forbidden and what remains uncertain. The workshop is complete only after the approved wording, corresponding technical evidence and final rendered language edition can be matched.
Workshop 3: Setup inspection
Start with this fictional context: A component must be inspected after positioning but before machine activation. The questionable translation has this effect: A stylistic rewrite joins steps and hides the explicit inspection checkpoint. Identify the controlling equipment condition, applicable document and the specific action that the target reader may infer. If a missing qualifier might change the instruction, make that qualifier visible in the review record.
The correction principle is: Keep separate testable steps and a clear sign-off point. Review source text, drawing and machine-specific approval together. Have the reviewer state in plain language what is permitted, what is forbidden and what remains uncertain. The workshop is complete only after the approved wording, corresponding technical evidence and final rendered language edition can be matched.
Workshop 4: Safety bulletin
Start with this fictional context: A correction applies to an identified group of machines and supersedes a previous instruction. The questionable translation has this effect: The translation republishes the old text without the correction or affected serial range. Identify the controlling equipment condition, applicable document and the specific action that the target reader may infer. If a missing qualifier might change the instruction, make that qualifier visible in the review record.
The correction principle is: Track the bulletin, scope and withdrawn editions. Review source text, drawing and machine-specific approval together. Have the reviewer state in plain language what is permitted, what is forbidden and what remains uncertain. The workshop is complete only after the approved wording, corresponding technical evidence and final rendered language edition can be matched.
Questions about translating machinery manuals
Can a safety manual be translated by AI alone?
A machine output may assist controlled drafting but should not replace qualified technical and language review for safety-critical instructions. For any actual equipment, authoritative manufacturer documentation and competent technical review take precedence over generic examples. A translator’s duty is to preserve technical and safety meaning, not to redesign the machine or write an alternative safety procedure.
Does ISO 20607 provide a universal lockout procedure?
No. Use the approved machine-specific and site-specific procedures, not generic instructions from a guide. For any actual equipment, authoritative manufacturer documentation and competent technical review take precedence over generic examples. A translator’s duty is to preserve technical and safety meaning, not to redesign the machine or write an alternative safety procedure.
What is residual risk?
It is risk that remains after the specified risk-reduction measures and must be communicated accurately. For any actual equipment, authoritative manufacturer documentation and competent technical review take precedence over generic examples. A translator’s duty is to preserve technical and safety meaning, not to redesign the machine or write an alternative safety procedure.
Should measurements always be converted?
No. Approved equipment values and compatible tools determine whether and how a conversion may be made. For any actual equipment, authoritative manufacturer documentation and competent technical review take precedence over generic examples. A translator’s duty is to preserve technical and safety meaning, not to redesign the machine or write an alternative safety procedure.
What if text conflicts with a figure?
Stop release and request an authoritative technical correction instead of guessing. For any actual equipment, authoritative manufacturer documentation and competent technical review take precedence over generic examples. A translator’s duty is to preserve technical and safety meaning, not to redesign the machine or write an alternative safety procedure.
What is the status of the edition?
ISO listed the 2019 edition as published with a revised edition under development when checked. For any actual equipment, authoritative manufacturer documentation and competent technical review take precedence over generic examples. A translator’s duty is to preserve technical and safety meaning, not to redesign the machine or write an alternative safety procedure.
Final principle and sources
A reliable translated manual permits a qualified user to recognise the same machine, read the same hazard, understand the same prerequisite and locate the same approved action. Safety-related language is precise because its boundaries matter. When the source is unclear, ask rather than guess. When the equipment changes, update the dependent language editions. When a mistake is found, provide a controlled correction and retire obsolete instructions.
