User Manual Translation: What EU Rules Require, and How to Get It Right Before January 2027
User manual translation means delivering a product’s instructions, safety information and warnings in the language each EU country requires for its users. EU product rules create the obligation and each Member State chooses the language. DEMA Solutions advises manufacturers to plan it as part of compliance, especially for machinery, because the Machinery Regulation (EU) 2023/1230 applies from 20 January 2027.
Notice: the Machinery Regulation applies from 20 January 2027. From that date, Regulation (EU) 2023/1230 replaces the Machinery Directive 2006/42/EC for machinery placed on the EU market. Instructions for use may be supplied in digital format, users can still ask for a paper copy, and instructions must be in a language users can easily understand, as determined by each Member State. If your machines ship after that date, your translated manuals have to meet the new rules. Our article on what the Machinery Regulation means for translated documentation covers the wider CE picture.
Who has to get user manuals ready for January 2027?
This guide is for the people who get manuals from the design office to users abroad: technical documentation managers, technical writers and localization managers, plus the quality, operations and procurement directors who approve the budget and carry the risk. Most work for manufacturers of machinery and regulated equipment, from HVAC and lifting equipment to packaging lines, automation and rail components, selling into several European markets at once. Their questions are practical: which rules require a translated manual, what changes in 2027, why some translations cause trouble in the field, what drives the cost of each edition and what to ask a supplier.
Which EU rules require translated instructions
Most EU product legislation follows the same pattern. The manufacturer must supply instructions and safety information in a language users can easily understand, as determined by the Member State where the product is made available. Importers carry the same duty, and distributors must check the right language version is there before they sell. The obligation follows the product into each market, whatever language the documentation was written in.
Machinery. Today the Machinery Directive 2006/42/EC applies, and from 20 January 2027 the Machinery Regulation (EU) 2023/1230 takes over. Article 10(7) of the Regulation requires the instructions for use, the safety information and the Annex III information in a language easily understood by users, as determined by the Member State concerned. Under section 1.7.1 of Annex III, written warnings on the machine itself follow the same rule, with pictograms preferred where they work. One narrow exception is worth knowing: section 1.7.4 allows maintenance instructions for specialised personnel mandated by the manufacturer or its authorised representative to be supplied in one official EU language those technicians understand. Instructions for operators, installers or the customer’s own maintenance staff are not covered by it.
Electrical, EMC and radio equipment. The Low Voltage Directive 2014/35/EU (Article 6(7)) and the Radio Equipment Directive 2014/53/EU (Article 10(8)) require instructions and safety information in a language easily understood by consumers and other end-users, as determined by the Member State concerned. The EMC Directive 2014/30/EU (Article 7(7)) applies the same rule to its instructions and use information. A single machine can fall under several of these acts at once, through its control cabinet or a wireless remote, and each adds content to translate.
Consumer products. The General Product Safety Regulation (EU) 2023/988 (Article 9(7)) requires clear instructions and safety information in a language easily understood by consumers, as determined by the Member State where the product is sold, unless the product can be used safely without them. Recall notices must also be available in the language or languages of each Member State concerned. Computers, smartphones and self-service terminals face further rules on top of this, because the European Accessibility Act requirements also govern how their instructions and product information are presented.
Toys. EU toy safety legislation requires instructions and safety information in a language or languages easily understood by consumers, as determined by the Member State concerned.
Medical devices. The Medical Device Regulation sets its own rules for labels and instructions for use, and the language is decided country by country, sometimes differently for professional and lay users. Our guide to EU MDR language requirements lists which documents need translating and where, and the page on medical device translation shows how we handle them.
The practical rule: if a product is sold in a country, its user manual must be available in the language that country requires. Some countries require more than one language, national rules change, and distributors often ask for more than the legal minimum, so a matrix of markets and required languages, reviewed whenever you enter a new country, is the safest way to keep track.
What changes for user manuals on 20 January 2027
For machinery, the Regulation changes how instructions can be delivered, not whether they need translating. Under Article 10(7), instructions may be supplied digitally if they clearly identify the product model. The manufacturer must then mark how to access them, make them printable, downloadable and storable on a device (also when embedded in the machine’s software), and keep them online for the machine’s expected lifetime and at least ten years after it is placed on the market.
Paper does not disappear. If the user asks at the time of purchase, the instructions must be supplied on paper, free of charge, within one month. Where machinery is intended for, or could reasonably be used by, non-professional users, the safety information essential for safe set-up and use must always be on paper.
None of this removes the language requirement: every digital version and every paper copy must exist in each required language. What digital delivery changes is visibility. If the German online manual has been updated and the Italian one has not, users see both. And the edition that shipped with a machine must stay accessible in every language for as long as the machine is in service. Change control matters more after 2027, not less.
What a user manual translation actually includes
Whether your teams call it user manual or instruction manual translation, the job is rarely a single document, and the most common planning mistake is to translate the manual and forget what surrounds it. Before you request a quote, list everything a user in that market will read: the operating, installation and maintenance instructions; the safety information, warnings and residual risk statements; the labels and markings on the product and its packaging; quick start guides and inserts; the interface texts on displays and control panels that the manual refers to; the text in illustrations, callouts and exploded views; the declaration of conformity where it travels with the product; and the digital versions, whether online help, downloadable PDFs or pages behind a QR code. Once that list exists, a checklist of what to send for an accurate quote helps you add the files, memories and references a supplier needs.
These pieces usually come from different departments and are sent for translation at different times, sometimes to different suppliers. That is how a user ends up reading “press RESET” in the manual while the display shows a different word, at the moment they most need the two to agree.
What makes user manual translation hard
A manual is functional text: someone will follow it with tools in their hands, sometimes near a hazard. Five features cause most of the difficulty.
Numbers and units. Torque values, pressures, temperatures, clearances and intervals must survive translation exactly. Decimal separators differ between languages, and units should only be converted when the source owner asks, with the conversion checked by someone who understands the engineering. These errors are rare, but they have real consequences, and a reviewer reading for style is the least likely to spot them.
Warnings. A warning has a deliberate structure: a signal word, the hazard, the consequence and how to avoid it. Each element must keep its weight, and the same warning must read identically in the manual, on the machine and on the label. Translated three slightly different ways, it looks like three different warnings.
Structure. Numbered steps, tables, cross-references and, in XML systems, reusable modules and conditional text for machine variants. A translation that breaks a sequence or a cross-reference makes the manual harder to use even when every sentence is correct.
Illustrations with text. Exploded views, wiring diagrams and screenshots often carry embedded labels. In a flat image, that text must be extracted, translated and put back, or the drawing rebuilt. Numbered callouts with a translated legend are far cheaper over a product’s life.
Interface references. Every quoted button name, menu path or display message must match what the user sees on the machine. That only works if interface strings and manual share the same approved terminology, ideally with the interface translated first. How to organise that across screens, alarm texts and character limits is the subject of our guide to HMI and software translation for machinery.
Layout, file formats and desktop publishing
Most of the cost and most of the errors in user manual translation are decided before translation starts, by the state of the source files.
Editable files, such as Word, InDesign, FrameMaker or DITA and other XML, can be translated directly and returned in the same format, ready to publish. Many manufacturers only have PDFs of older manuals. A PDF can be translated, but it first has to become an editable file again, which is what DTP file preparation does. Original files always give a faster, cleaner result.
Translated text usually runs longer than the source. In fixed page layouts, tables and callout boxes, that expansion has to be absorbed without shrinking type or cutting off text, and fonts, page breaks and the table of contents need checking in every language. That is the job of multilingual desktop publishing, best done inside your original files. Writing for translation helps too: short sentences, one instruction per step, one name per component and no text inside images cut cost and errors in every language you add.
One terminology for the manual, the interface and the spare parts
A product line is described in the operating and service manuals, the display texts, the spare parts catalogue and the training material. Translated separately, the same component ends up with several names per language, a technician cannot find the manual’s term in the catalogue, and a dealer’s correction in one document never reaches the others.
The fix is a multilingual glossary of component names, controls, display messages and safety terms, approved once by your engineers or subsidiaries and used on every document. Our guide to keeping technical terminology consistent across translators and suppliers shows it is less work than it sounds. For groups whose subsidiaries or distributors re-check translations, the glossary is also where their feedback belongs, captured once instead of in every review.
Versions, revisions and digital instructions
A user manual is updated with every product change, and every update has to reach every language. This is where costs and errors pile up when the process is not controlled.
A translation memory stores every sentence you have already translated and approved. When the next edition arrives, only new and changed content is translated, and unchanged sentences keep their approved wording. The memory should belong to you, in a portable format. Contracts rarely say who owns it, which is why ownership of your translation memory is worth settling at the start.
Good change control rests on a few habits. Every language carries the same edition number and date as the source. Changes reach every language before release, not only the main markets. Approved corrections from engineers or dealers update the memory and glossary. And for machinery after 2027, the downloadable manual, the paper copy and the version embedded in the software must be the same edition, while earlier editions stay available for machines already in the field.
Quality checks that matter for manuals
The ISO 17100 standard requires every translation to be revised by a second qualified linguist against the source. For manuals, that reviser should know the technical domain, because the errors that matter are rarely grammatical: a wrong value, a step out of order, a term that does not match the display, a warning that has lost its force.
Automated checks complement revision by comparing numbers, units, tags and glossary terms between source and target. A final check in the laid-out document catches what only appears on the page, such as truncated cells, wrong cross-references and missing callouts. When your engineers or dealers review, their input works best focused on terminology and technical accuracy, recorded in the glossary rather than in comments on one PDF.
Can machine translation be used for user manuals?
For recurring content with stable terminology, machine translation post-edited by a qualified linguist can be the right route, especially when it runs on your own approved glossary and memory. For safety information, warnings and new content, human-led translation or a full post-edit with a second check is safer. Raw machine output is never acceptable in a manual users rely on. Which content suits post-editing and which does not is covered in our guide to post-editing technical documentation.
What drives the cost of user manual translation
The per-word rate is only one factor. The real cost of a product manual translation depends on how much text is genuinely new, the file format and layout work, illustrations with text, the number of languages and how much terminology must be built from scratch.
As an illustrative example, take a new edition where most content is unchanged. With a clean translation memory, only new and changed sentences are translated in full and the rest is reused and checked. With no memory, or one scattered across former suppliers, the edition is effectively translated from scratch, in every language, every time. Procurement teams should compare offers on the full cost per edition, including reuse, layout and review, not on the rate alone. Our article on what drives technical manual translation costs goes into each factor in detail.
A step-by-step process for translating a user manual
Define the scope. From your market and language matrix, list every document in the set and note which edition is being translated, which earlier edition exists in each language, and the shipment dates, including machines placed on the market after 20 January 2027.
Prepare the source. Collect editable files rather than PDFs, freeze the source text and separate text from images. If only PDFs exist, plan the conversion as its own step.
Gather your linguistic assets. Bring existing memories and glossaries together, including those held by former suppliers, resolve conflicting terms, and confirm interface terminology first so the manual can quote it exactly.
Translate and revise. Specialist linguists translate, or post-edit controlled machine translation where the content allows, and a second qualified linguist revises.
Check and lay out. Run automated checks, lay out the manual in its original format, then check the finished pages in every language.
Release together and keep the corrections. Release all languages of the edition at once, in every format, and feed approved corrections back into the memory and glossary.
What to ask a user manual translation services supplier
User manual translation services look similar on paper, so the questions you ask before choosing a supplier matter. These are the ones that reveal the most:
- Can you work directly in our formats (InDesign, FrameMaker, DITA or our content system output) and return files ready to publish?
- Who revises each translation, and do they have experience with our type of equipment?
- How do you check numbers, units, warnings and interface references?
- Who owns the translation memory and glossary, and will you deliver them in portable formats?
- How do you report reuse from the memory, and how is it reflected in the price of each edition?
- How do you handle updates, so every language follows the same edition?
- How are corrections from our engineers or distributors captured for next time?
A wider checklist is in ten questions for choosing a technical translation company.
How DEMA Solutions translates user manuals
Manuals rarely travel alone, so we translate them together with the safety information, labels, interface texts and declarations that ship with the product. Our technical translation services follow an ISO 17100 certified process in which every translation is revised by a second qualified linguist, and the specialist linguists in our teams in Italy, Serbia and Spain stay with the same technical domain. For a manual project, that looks like this:
- Terminology is fixed first, so the manual uses the words on the machine’s display and in earlier editions.
- Reused text is not taken on trust: in safety-related projects, translations drawn from the memory are checked again before delivery.
- Layout happens in house, in your original files, for print or online publication; scanned or locked PDFs can be rebuilt as editable files.
- The assets remain yours: memory and glossary grow with each edition and are delivered in TMX and TBX, with a clear report of what was reused.
One Italian manufacturer of industrial equipment ships every machine with operating and maintenance manuals, safety information and HMI texts in the buyer’s language. Because the memory recognises content shared by machine variants and the same linguists work on the same product families, each new manual begins from text that has already been approved. The details are in the industrial manufacturer case study.
Where TUBE fits
Most manual editions repeat the safety chapter, the maintenance tables and whole procedures from the one before. TUBE reuses those approved sentences automatically, with your glossary and memory steering machine translation for the rest. DEMA sets up the glossary and memory, or aligns past manuals into one, and a leverage report shows how much of each edition was carried over.
Frequently asked questions
For most regulated products, yes. Machinery, electrical and radio equipment, toys, consumer products and medical devices must be accompanied by instructions and safety information in a language users in the country of sale can easily understand, as decided by that Member State.
Yes. From 20 January 2027, Article 10(7) of Regulation (EU) 2023/1230 requires instructions for use and safety information in a language easily understood by users, as determined by each Member State. They may be supplied digitally, but users can ask for a free paper copy at purchase, and safety information for non-professional users must always be on paper.
In most cases, yes. Under the Machinery Regulation, only maintenance instructions intended for specialised personnel mandated by the manufacturer or its authorised representative may be supplied in one official EU language those technicians understand. Instructions for the customer's own staff follow the general language rule.
It depends on length, number of languages, file format, the amount of layout work and how much content is already in your translation memory. Updates to an existing manual are usually much faster than a first edition, because only new and changed content is translated.
A second qualified linguist should revise the translation against the source. Your engineers or local dealers are best placed to approve terminology, ideally once in a shared glossary rather than in every manual.
User manuals are written for the people who operate the product, so clarity and safety information come first. Technical manuals, such as service documentation, are written for technicians. Both need consistent terminology, checked numbers and controlled versions.
A complete manual translation service covers more than the text. It starts with preparing the source files (InDesign, FrameMaker, Word, XML or, if nothing else exists, PDF), continues with translation by linguists who know the product field, using your glossary and translation memory, and adds revision by a second linguist. It ends with layout in the target language and a final check of the print-ready or digital file. When the manual changes with each machine version, the translation memory means only new or changed text is translated at full rate.
