User Manual Translation: What EU Rules Require, and What Changes in January 2027
User manual translation means delivering your instructions, safety information and warnings in a language users in each market can easily understand, as each EU country decides. DEMA Solutions advises manufacturers to plan it as part of compliance, especially for machinery: 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 set by each Member State. If your machines ship after that date, your translated manuals have to meet the new rules. Read what the Machinery Regulation means for translation.

When a user manual must be translated
In the EU, a product’s instructions and safety information have to reach users in a language they understand. Which rules apply depends on the product:
- Machinery. Today the Machinery Directive 2006/42/EC, and from 20 January 2027 the Machinery Regulation (EU) 2023/1230. Instructions for use, safety information and the declaration of conformity must be in the language required by the country where the machine is placed on the market.
- Consumer products. The General Product Safety Regulation (EU) 2023/988 requires instructions and safety information in a language consumers can easily understand, as decided by the Member State where the product is sold.
- Electrical equipment, radio equipment, toys and other regulated products. Their own EU rules carry similar language requirements for instructions and safety information.
- Medical devices. The Medical Device Regulation has its own requirements for labels and instructions for use. See medical device translation.
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, and a distributor or customer may ask for more than the legal minimum.
What changes for user manuals on 20 January 2027
For machinery, the Machinery Regulation changes how instructions can be delivered, not whether they need to be translated:
- Digital instructions are allowed. Instructions for use may be supplied in digital format, for example as a download linked from the machine or its packaging.
- Paper on request. If the user asks at the time of purchase, the manufacturer must supply the instructions on paper, free of charge, within one month.
- Online for at least ten years. Digital instructions must be printable and downloadable, and stay online for the expected lifetime of the machine and at least 10 years after it is placed on the market.
- Safety information for non-professional users. Where machinery is intended for non-professional users, the safety information essential to put it into service and use it safely still has to be supplied on paper.
- Language is still set by each country. Instructions must be in a language users can easily understand, as determined by the Member State concerned. Digital delivery does not remove the translation requirement; it multiplies the formats you have to keep up to date.
Digital instructions make it easier to publish corrections, but they also make inconsistencies visible. If the German online manual is updated and the Italian one is not, both are in front of users at the same time. That is why change control matters more after 2027, not less. Our Machinery Regulation article covers the wider documentation and CE requirements.
What a user manual translation includes
A user manual is rarely one document. When you plan a translation, list everything a user in that market will read:
- The manual itself: operation, installation, maintenance, troubleshooting
- Safety information: warnings, hazard statements, residual risks
- Labels and markings on the product and packaging
- Quick start guides and inserts
- Interface texts referred to in the manual, such as display messages and button names
- Illustrations and callouts on drawings and exploded views
- The declaration of conformity, where it ships with the product
- Digital versions: online help, PDF downloads, pages linked from a QR code
The interface texts deserve special attention. If the manual says “press RESET” and the translated display shows a different word, the user is lost at the exact moment they need the manual.

Start from a source that can be translated well
Most of the cost and most of the errors in user manual translation are decided before translation starts.
Send editable files. Word, InDesign, FrameMaker, DITA or other XML can be translated directly and returned in the same format. Many manufacturers only have PDFs. A PDF can be translated, but it first has to be converted into an editable file, which adds a step. Our file preparation and desktop publishing teams can make PDFs editable, but the original file is always better.
Write for translation. Short sentences, one instruction per step, the same term for the same component. A source written by several authors over several years usually contains three names for one part, and each of them gets translated.
Fix the terminology first. An approved glossary of component names, controls and warnings, in every language, keeps the translated manual consistent with the interface, the spare parts catalogue and the previous edition. See how to keep technical terminology consistent.
Updates and new versions: translate only what changed
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 if the process is not controlled.
With a translation memory, every sentence you have already translated and approved is stored. When the next edition arrives, only new and changed content needs translating, and unchanged sentences keep exactly their approved wording. The memory should be yours, so you can take it with you. See who owns your translation memory.
Good change control for translated manuals means:
- Every language follows the same version as the source, with a clear edition number and date.
- Changes are translated in every language before the new edition is released, not only in the main market languages.
- Approved corrections from dealers or engineers update the memory and glossary, so they are not lost in the next edition.
- Digital and printed versions match. After 2027, the downloadable manual and the paper copy a user requests must be the same edition.
For where the cost of each edition really comes from, see technical manual translation costs.
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. For safety information, warnings and new content, a human-led translation or a full post-edit with a second check is safer. Raw machine output is never acceptable for a manual users rely on. See when machine translation post-editing is good enough for technical documentation.
A checklist before you send a user manual for translation
- Which markets and languages, including countries that require more than one language
- Which edition is being translated, and which earlier edition is already translated
- Editable source files, or PDFs that need to be converted first
- Approved glossary and existing translation memory, if you have them
- Interface texts and labels referred to in the manual
- Illustrations with text to translate
- Print, PDF, online or all three
- Who reviews on your side (engineers, dealers, subsidiaries) and how their feedback is captured
- Deadline linked to the shipment date, and for machinery, to 20 January 2027
How DEMA Solutions translates user manuals
We translate user, installation and maintenance manuals for manufacturers, 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, with a second qualified linguist revising every translation. If you are comparing suppliers, see how to choose a technical translation company.
- Prepare the documentation set: markets, languages, formats, previous editions, existing memory and glossary.
- Build or clean your glossary and translation memory, so the manual matches the interface and earlier editions.
- Translate with specialist linguists, or controlled machine translation post-editing where the content allows it.
- Run systematic checks on terminology, numbers, units, tags and formatting.
- Lay out the translated manual with our in-house DTP team, in your original files, ready to print or publish online.
- Keep the corrections: approved changes go into your memory and glossary for the next edition.
For one Italian manufacturer of industrial equipment, every machine ships with operating and maintenance manuals, safety information and interface texts in the destination language. A translation memory that recognises content repeated across machine variants, an approved glossary and the same linguists on the same product families mean each new manual starts from what has already been approved. Read the industrial manufacturer case study.
“We have been working with DEMA for a few years now on the translation of manuals: they are a great partner, professional, fast, and efficient. Our native-speaking dealers have also praised the quality and accuracy of the translations.”

Where TUBE fits
For manufacturers who update manuals with every product release, TUBE keeps the language of each edition under your control. Your glossary and translation memory control machine translation, every approved translation goes into a memory you own, and leverage reporting shows how much of each edition comes from reuse.
Frequently asked questions
For most regulated products, yes. Instructions and safety information must be in a language users in the country of sale can easily understand, as decided by that Member State.
Yes. From 20 January 2027, instructions for use must be in a language easily understood by users, as determined by each Member State. They may be supplied digitally, but users can ask for a paper copy.
For machinery, instructions may be supplied in digital format, but users can still ask for a paper copy, and safety information for non-professional users must still be supplied on paper. Each digital version must also be translated.
It depends on length, number of languages, file format 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.
Yes, but the PDF first has to be converted into an editable file, and the layout rebuilt in each language. Original files such as Word, InDesign or XML give faster and more accurate results.
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 the 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 and maintenance documentation, are written for technicians. Both need consistent terminology and checked numbers.
