Does the EU Machinery Regulation Allow AI Translation for Instructions for Use
Yes. The EU Machinery Regulation lets you use AI translation for a machine's instructions for use, on one condition: a qualified engineer reviews the output before it ships, and the version meets the language your target Member State sets. Regulation (EU) 2023/1230 applies from 20 January 2027, and it treats the translated instructions as part of the product, not as an afterthought.
AD VERBUM is an EU-hosted AI translation company that routes every machinery manual through a client-tuned large language model and then certified technical review, human-verified under ISO 17100 and ISO 18587, so the German, French or Finnish instructions carry the same safety meaning as the source.
Machine builders feel the pressure now, because the deadline is close and the technical translation load behind one product line is larger than most teams expect. We at AD VERBUM translate the operating, maintenance and safety manuals across the engineering and technical documentation a single machine generates, and the buying conversations are already under way at electronica 2026 in Munich, 10 to 13 November, where power electronics and embedded systems vendors are preparing manuals for exactly this rule.
What the EU Machinery Regulation requires
The regulation replaces Directive 2006/42/EC, the machinery directive that governed the EU for two decades, and it carries legal force in every Member State from 20 January 2027. The EU-OSHA summary sets out the scope: machinery, safety components, lifting accessories and partly completed machinery all fall inside it.
Article 10 puts the obligations on the manufacturer. You draw up the technical documentation, sign the EU declaration of conformity, and supply the instructions for use. The instructions, the safety information and the declaration must appear in a language the end user understands easily, and each Member State decides which language that is. Sell one excavator across Germany, France and Finland and you manage three mandatory language versions, not one.
The records duty runs long. Technical documentation and the declaration of conformity stay available for at least 10 years after the machine goes on the market. The translated instructions you release in 2027 may still need to be reproducible, and correct, well into the late 2030s.
Where AI translation fits, and where it stops
AI translation earns its place on machinery documentation because the volume is high and the terminology repeats. A client-tuned LLM constrained by your Translation Memory and Term Base produces far more coherent output than the segment-level machine translation that fails regulated documents on context and consistency. The model drafts, and a certified engineer owns the result.
The hybrid handles the bulk of a machinery manual well:
Operating and maintenance procedures, where the same instruction recurs across models and model years.
Parts catalogues and service bulletins, where part numbers and units must survive untouched.
Installation and commissioning sections, where phrasing follows a house pattern the term base already holds.
Interface strings and on-screen messages that mirror the printed manual.
Two document types never ship on machine output alone: the safety warnings and residual-risk statements, and the EU declaration of conformity. Those carry the legal weight, so a qualified reviewer signs them off, the same triage logic we apply when sorting medical device documents into hybrid versus full human translation.
The real risk: a divergent safety warning
Picture a guard-removal warning that reads one way in the English source and slightly softer in the translated manual. The machine injures an operator, the investigation pulls the instructions, and the divergence between language versions becomes the manufacturer's problem. This is the failure mode the regulation is built to prevent, and an unreviewed AI draft of a safety-critical instruction creates liability rather than saving time.
Certified review closes that gap. Our post-editing runs to ISO 18587, the standard for full human post-editing of machine output, under which a named, qualified post-editor takes responsibility for the final text. The engineer checks that every warning, torque value and clearance reads identically across source and target.
Digital instructions and the ten-year duty
The regulation allows digital instructions, a change the old directive resisted. You can publish the manual online rather than print it, provided it stays available and downloadable for at least 10 years, and you supply a paper copy free of charge when the buyer asks at purchase. The same debate already ran in medical devices, where we covered replacing a printed IFU with an electronic one under Regulation (EU) 2021/2226.
Digital does not loosen the translation duty, it tightens it. An online manual updates, and every update has to propagate across every language version at once. Under Article 18, anyone who makes a substantial modification to a machine after it is on the market becomes the manufacturer for that change, with the full documentation and translation obligations that follow.
How we at AD VERBUM translate machinery manuals
Our workflow is built so the language versions never drift from the source. AD VERBUM runs client-tuned open-weight models on EU-hosted infrastructure, with no public cloud and no training on your data, and the steps run in a fixed order:
Inventory every manual by product family and by the Member State language each market demands, so nothing is missed before the 2027 deadline.
Extract and lock the terminology into a client Term Base, so part names, units and safety terms stay fixed across the whole product line.
Generate the draft with a client-tuned LLM constrained by your Translation Memory and Term Base, our AI+HUMAN hybrid translation applied from the first segment.
Review with a certified engineer who owns the safety warnings and the declaration of conformity, verified under ISO 17100 and ISO 18587.
Archive the source, the target and the review record so the full set stays reproducible for the 10-year retention window.
The result reads as an engineer wrote it, in each market's language, with an audit trail behind every warning. The same approach answers the parallel question on devices, whether MDR allows AI translation for IFUs and labelling.
Our machinery translation services
Our translation services for regulated sectors run on ISO 27001 and ISO 42001 certified, EU-hosted infrastructure, with no reliance on public cloud tooling for core processing. Every project runs through our AI+HUMAN hybrid workflow: we ingest client Translation Memories and Term Bases first, our proprietary LLM-based LangOps System generates output constrained by client terminology on client-tuned open-weight models, and our certified subject-matter experts review for technical accuracy and regulatory compliance. Our QA is aligned to ISO 17100 and ISO 18587, with sector-specific requirements such as the EU Machinery Regulation (Regulation 2023/1230) applied where relevant. We serve Manufacturing, Automotive, Defense, Legal and Life Sciences clients across 150+ languages with 3,500+ subject-matter linguists. For teams preparing secure, EU-hosted translation ahead of 20 January 2027, contact us to discuss your security and compliance requirements directly.
FAQ
Does the EU Machinery Regulation allow AI translation for instructions for use?
Yes, provided a qualified engineer reviews the output and the version meets the language each Member State sets under Regulation (EU) 2023/1230. The regulation applies from 20 January 2027 and treats the translated instructions as part of the product. Unreviewed machine output is not acceptable for safety-critical text.
When does Regulation (EU) 2023/1230 apply?
It applies from 20 January 2027 and replaces Directive 2006/42/EC, the previous machinery directive. Machinery lawfully placed on the market before that date may still be made available. The date a machine is placed on the market decides which rules govern its documentation.
What language must machinery instructions be in?
Regulation (EU) 2023/1230 requires the instructions, safety information and EU declaration of conformity in a language the end user understands easily, and each Member State sets which language that is. A manufacturer selling across several countries manages one mandatory version per market. Germany, for example, requires German for the instructions and both declarations.
Can machinery instructions be digital only?
Yes. The regulation allows digital instructions that stay available and downloadable for at least 10 years after the machine is placed on the market, with a free paper copy on request at purchase. Each language version must still be complete and accurate. A digital manual that updates must propagate the change across every language at once.
How long must machinery technical documentation be kept?
At least 10 years after the machine is placed on the market, under Regulation (EU) 2023/1230. That covers the technical documentation and the EU declaration of conformity, which means translated instructions must stay reproducible for a decade. AD VERBUM archives the source, target and review record for the full window.
Who is responsible if the translated safety warning differs from the source?
The manufacturer. Divergence between language versions is the manufacturer's responsibility under Regulation (EU) 2023/1230, and under Article 18 anyone making a substantial modification becomes the manufacturer for that change. Certified review under ISO 18587 is how AD VERBUM keeps every warning identical across languages.
