Regulation (EU) 2023/1230 replaces the old Machinery Directive and applies from 20 January 2027, tightening the rules on the documentation that accompanies equipment placed on the EU market. For manufacturers and importers, this means reviewing not just the technical content of manuals, but how and into which languages they are translated. Treating manual translation as a last-minute formality under this regime creates real compliance exposure.
The new regulation keeps a core requirement in place: instructions must be available in the official language of each country where the machine is placed on the market or put into service. This applies to every destination member state, not just the manufacturer's home country. A machine sold in Portugal, Spain and Poland needs manuals in Portuguese, Spanish and Polish, each developed to the same technical standard.
What changes under Regulation 2023/1230
The regulation replaces Directive 2006/42/EC and extends its scope to cover AI-based safety components embedded in machinery. It also strengthens digital traceability obligations, allowing instructions to be supplied in digital format, but only under specific conditions.
Points that matter for anyone managing technical documentation:
- Digital instructions are permitted, provided the manufacturer offers a durable means of access and tells the user how to obtain a paper version free of charge on request.
- Clear, unambiguous language is required for safety instructions, with terminology consistent across the manual, labelling and declaration of conformity.
- Mandatory updates to documentation whenever a substantial modification is made to the machine, including all translated versions.
- AI-based safety components require additional documentation on expected system behaviour, which also needs translating for each market.
Ambiguity in a translated safety warning is not a stylistic detail. It is the kind of failure that triggers action from market surveillance authorities and, in the event of an accident, civil liability for the manufacturer.
Technical terminology and consistency across documents
An industrial machinery manual spans several technical domains at once: mechanical engineering, electronics, control software and, increasingly, AI systems. The translation has to hold the same terminology throughout the document and across related documents, including the EC declaration of conformity, safety data sheets and the machine's own labelling.
Some terms that commonly cause inconsistency between translated versions:
| Source term (EN) | Correct technical rendering | Common error |
|---|---|---|
| Safeguarding | Protective device / safeguarding | Generic "protection" |
| Residual risk | Residual risk | "Remaining risk" |
| Intended use | Intended use | "Expected use" |
| Emergency stop | Emergency stop | "Panic button" |
| Foreseeable misuse | Reasonably foreseeable misuse | "Expected misuse" |
Using a shared translation memory and a glossary validated by the manufacturer stops the same term appearing in three different forms depending on which chapter it falls in, a problem that surfaces easily when work is split across several translators without central coordination. We covered this same inconsistency risk in detail when discussing translating industrial maintenance manuals from English to Spanish, where small terminology drift between the user manual and the maintenance manual confuses operations teams on the ground.
Choosing the right service tier for regulated manuals
Not every document tied to a machine carries the same regulatory weight, and that should determine which translation tier is used.
- Declaration of conformity, safety warnings and assembly instructions: documents with direct implications for legal compliance and operator safety. This is where the Estratégica tier fits, with three linguists (translator, editor and QA reviewer), an ISO 17100 audited workflow and two rounds of post-delivery revision. It is the only tier with review by a second linguist, relevant when a translation error could trigger non-compliance findings from a notified body.
- General user manuals and internal operating procedures: when content is descriptive rather than normative, the Standard tier, following ISO 18587, with M21Global's own translation engine, full post-editing by a linguist and project manager quality control, is usually sufficient.
- Parts catalogues, technical FAQs or large reference documentation: the IAH+ tier covers high volumes with selective human review of around 30% of the most error-prone segments, suited to supporting material rather than normative text.
All three tiers include full desktop publishing, which preserves diagrams, step numbering and safety symbols in the original layout, a critical point in technical manuals where the position of a warning icon carries regulatory meaning.
How M21Global supports compliance with Regulation 2023/1230
M21Global has worked with technical and industrial documentation for more than 20 years, holding ISO 17100:2015 certification audited by Bureau Veritas and ISO 18587 certification for machine translation post-editing. We have translated more than 445 million words, including machinery manuals, declarations of conformity and safety documentation for manufacturers exporting into the UK, Spain, France, Germany and Portuguese-speaking markets.
If the company needs to translate machinery manuals to meet Regulation 2023/1230 across several European markets, the technical translation service page outlines the process and the service tiers available. Teams that have already managed user manual translation projects under other regulatory frameworks will also find the user manual translation services article useful.

Frequently Asked Questions
Does Regulation 2023/1230 require manuals translated into every EU language?
It requires translation into the official language of each member state where the machine is placed on the market or put into service, not into every EU language regardless of destination.
Can machine instructions be provided in digital format only?
Yes, as long as the manufacturer provides a durable means of access and makes a paper version available free of charge when requested by the user.
Which service tier is recommended for an EC declaration of conformity?
The Estratégica tier, since it includes review by a second linguist and an ISO 17100 audited workflow, which suits documents with direct legal implications.
Does manual terminology need to match the machine's labelling?
Yes, terminology inconsistency between the manual, labelling and declaration of conformity is one of the most common issues flagged during market surveillance checks.
