Machinery Regulation 2023/1230: The Hidden Risk in Your Documentation

The new EU Machinery Regulation (EU) 2023/1230 takes effect on 20 January 2027. It fully replaces the current Machinery Directive (2006/42/EC), with no transition period.

From Milengo’s perspective as a technical translation provider, three changes in the Regulation matter most for documentation and compliance teams: the shift to digital instructions with a ten-year online availability requirement, new cybersecurity requirements, and an expanded scope for AI-based safety components. All three increase the volume of content that has to be translated into every target language, starting in 2027 and most manufacturers have not yet built it into their planning.

How the Machinery Regulation replaces the Machinery Directive 2006/42/EC

The Machinery Directive 2006/42/EC has governed EU machinery compliance for nearly two decades. The Machinery Regulation (EU) 2023/1230 replaces it outright, with no transition period and changes more than its name.

Regulation (EU) 2023/1230 applies directly and uniformly across the EU, without national transposition by individual member states. This creates more legal certainty than the previous directive, but changes little about the core obligation: operating instructions, safety information, and the declaration of conformity must still be provided in the official language of each destination country, which means specialist technical translation stays mandatory, not optional.

At a glance: how translation obligations change under the Regulation

Digital instructions: what Article 10 actually requires.

What is new is the option to provide instructions for use in a purely digital format instead of on paper. Article 10 of the Regulation sets fixed conditions for this: the manufacturer must mark on the machinery, its packaging, or an accompanying document how to access the digital instructions, and must present them so users can print, download, and save them to a device, so they stay accessible even during a breakdown. If the user requests a paper copy at the time of purchase, the manufacturer must still provide one free of charge within one month. Safety information that is essential for non-professional users must remain available in print regardless of format.

The ten-year documentation obligation

The digital option also comes with a longer-term obligation: instructions must stay accessible online for the expected lifetime of the machinery, and in any event for at least ten years after it is placed on the market. The same ten-year rule applies if the EU declaration of conformity is also provided digitally rather than on paper. That turns documentation into a standing commitment, not a one-time deliverable: every translated language version has to stay live, accurate, and traceable to the exact product version it describes for a decade or more which means your hosting and translation setup needs to survive server migrations, CMS changes, and, in many cases, outlast the person who managed the original project.

Cybersecurity and AI: the underestimated changes in the Machinery Regulation

Two substantive changes in Annex III and Annex I of the Regulation increase the actual translation scope, regardless of format.

New mandatory content driven by cybersecurity.

Clauses 1.1.9 and 1.2.1 require, for the first time, protection against manipulation of safety-relevant software and hardware. Manufacturers must inform users which software is necessary for safe operation and how it is made accessible. This is new, safety-critical instructional content that requires the same careful specialist translation as any other safety notice.

Broader scope for AI-based safety components.

Annex I now explicitly names machinery with self-learning, AI-based safety functions as a high-risk category requiring assessment by a notified body. Anyone developing adaptive robotics or self-learning safety logic will need the full documentation package, translated into every target language, from 2027 onward. The leaner documentation routes that were previously common no longer apply to this product category.

For machinery, electronics, and automation companies with connected or AI-based products, this simply means: more content, more languages, more update cycles. Planning for this early avoids bottlenecks just before the deadline.

Other changes: labeling and partly completed machinery

Every language version now carries equal legal weight

The Machinery Directive treated the source-language instructions as the authoritative version and everything else as a derived translation. The Regulation drops that hierarchy. Once every language version is legally equivalent, there is no fallback copy to point to if a translated safety warning is ever disputed. This means the translation itself has to be right the first time, not just close enough to the “real” version.

Partly completed machinery needs its own translated documentation

Suppliers of partly completed machinery – subassemblies intended for further integration rather than standalone use – must provide assembly instructions and an EU declaration of incorporation in the destination country’s language, not just the final integrator. That pushes a translation obligation earlier into the supply chain than many manufacturers currently plan for.

Germany’s MaschinenDG: an extra language rule to track

Germany’s national implementing act, the MaschinenDG, adds country-specific language requirements on top of the EU Regulation. It enters into force on 6 December 2025 and requires instructions for use, Annex III safety information, EU declarations of conformity, assembly instructions, and EU declarations of incorporation to be provided in German for the German market. Failing to meet this can trigger regulatory penalties in Germany specifically, on top of whatever the EU Regulation requires elsewhere.

For manufacturers selling into Germany, this means German-language documentation is not optional even where the EU Regulation alone might allow other language choices. Confirm the current requirements against the official MaschinenDG text and, ideally, with legal counsel before relying on this for compliance planning – implementing rules like this vary by member state and can change.

Where this will show up in your documentation process

• Cross-language version control. The ten-year online availability requirement means every safety-relevant update must reach every language version at the same time, with traceable documentation.
• Terminology consistency. Safety-critical terms must remain identical across all languages and product versions. Discrepancies stand out immediately during a regulatory audit.
• Depth of specialist review. Machine and AI-assisted translation alone does not meet the “easily understandable” standard required for safety-critical texts. This content needs expert review in the target language by specialists from the relevant industry.

What manufacturers should prepare now

1. Audit your documentation inventory. Record every active product line, every target market, and the current language status of the instructions, safety information, and declaration of conformity.
2. Prioritize AI-based and connected products. These product lines require assessment by a notified body and an audit-ready, fully translated documentation package.
3. Manage terminology centrally. A vetted, multilingual terminology database keeps technical terms consistent across versions and languages.
4. Link your change process to translation. Every safety-relevant design or software change should automatically flag all language versions for updating.
5. Set an internal deadline. Decide, per product line, when you will document exclusively under the new Regulation internally, rather than waiting until December 2026 to start.

How Milengo can help

This is exactly where an approach that combines AI technology with human subject-matter expertise proves its worth. Milengo’s technical translation services combine AI-assisted translation technology with human subject-matter experts, so that safety-critical content is translated quickly and accurately.

Milengo’s online terminology review feature and platform integrations keep every language version of your instructions consistent connected directly to the systems your technical documentation team already uses. LQA dashboards also give you constant visibility into how robust your translation quality really is across every language, well before a regulatory audit is on the horizon.

In brief

The Machinery Regulation (EU) 2023/1230 rewards manufacturers who treat translation as a core part of their compliance infrastructure from the start. Those who begin now with a clear inventory, centralized terminology, and a translation partner built for ongoing updates will reach January 2027 with a clear plan.
