German to English technical translation for machinery, plant engineering and technical documentation
- ISO 17100 and ISO 9001, audited by DEKRA
- Operating instructions under Machinery Regulation (EU) 2023/1230, applicable from January 2027
- A terminology database and translation memory for each client
- Native-speaker specialist translators with a technical background
Manuals and CE documentation need specialist translation
Technical translation is the specialist translation of operating and maintenance instructions, data sheets, CE documentation and training material from mechanical engineering, plant engineering and industry into another language. For machinery, the rules change on 20 January 2027: the Machinery Regulation (EU) 2023/1230 changes the language requirement for operating instructions and, under certain conditions, allows them in digital form only.
Typical jobs:
- manuals for machinery delivered to several EU member states
- spare parts catalogues with a high reuse rate from the translation memory
- terminology projects that consolidate documentation grown inconsistent over the years
Four steps from file to delivery
- Request
A file or text sample, target language, target country, purpose and requested date are enough for a reliable quote.
- Quote
Your repetition rate is calculated before the quote. A quote is without obligation.
- Translation and revision
Native-speaker specialist translators with a technical background, dual control principle on every translation.
- Delivery
In structured formats the markup is preserved, so the translation flows back into your system without manual rework.
For operating instructions, name your target markets and say whether user and maintenance instructions are separate documents. Your target markets decide which language versions the quote has to cover.
Revision matters most in warnings and operating steps
ISO 17100, the international standard for translation services, requires a second qualified specialist to revise every translation before delivery, which is the dual control principle. In technical documentation the revision matters most in warnings and operating steps, where a misreading becomes a safety issue.
Translation memory and file format affect the price
Segments that have already been translated are reused from the translation memory, which lowers the price. Name the format in your request, as it markedly affects effort and price. The general basis of billing is explained under specialised translations.
Document types run from manuals to patent specifications
| Criterion | Details |
|---|---|
| Document types | Operating and user manuals, maintenance manuals, safety instructions, technical data sheets, spare parts catalogues, training materials, patent specifications |
| Industries | Mechanical engineering, plant engineering, automotive, conveyor technology, energy and environmental technology, process engineering, laboratory and air-conditioning technology, IT and telecommunications |
| Formats | Word, Excel, PowerPoint, FrameMaker, QuarkXPress and AutoCAD; other file formats on request |
Beyond translation: interpreting at factory acceptance tests and audits.
Test report, circuit diagram, maintenance contract: we translate other technical documents too. Name your document type in the request.
Terminology approvals and layout sign-offs in technical documentation often need direct discussion, so proximity matters more here than in other fields. The Ruhr region and Westphalia form one of Germany’s densest concentrations of mechanical and plant engineering, with conveyor, environmental and energy technology, process engineering and automotive suppliers in Dortmund, Bochum, Hagen, Witten and the Sauerland.
Machinery Regulation changes language and format rules
The Machinery Regulation (EU) 2023/1230 replaces the Machinery Directive 2006/42/EC. From January 2027, machinery may only be placed on the EU market under its rules. For translation, two changes count: which language the operating instructions must be in, and whether they may be supplied in digital form only.
Change 1: the member state's official language is no longer the test
The Directive tied the instructions to the official language of the member state. The Regulation drops that wording and asks for a language easily understood by users, as determined by the member state concerned, so review your language matrix market by market instead of carrying it over from past practice. One exception saves cost: maintenance instructions for specialised personnel mandated by the manufacturer may be written in a single official EU language that this personnel understands (Annex III, 1.7.4). Keep them as a separate document, and only the user instructions need every market language.
Change 2: digital-only instructions are allowed, with an obligation to keep them online
Under Article 10(7), instructions may be supplied in digital form only, provided the machine states where to find them and the format can be printed and saved. On request at the time of purchase, a free paper copy must follow within one month, and consumer machinery still comes with the safety information on paper. The instructions must stay online for the machine’s lifetime, at least ten years after it is placed on the market.
Before the deadline, take stock of the existing language versions, match them against your target markets, separate user and specialist content, and settle the terminology before any new translation begins.

Operating instructions are part of the product
If the operating instructions are missing in the required language or cannot be understood, the machine is non-compliant. After an accident, they become the central piece of evidence in the product liability question. That is why different rules apply to them than to marketing copy or general technical translation, and three areas carry the most weight.
Signal words keep their ranking
Safety warnings use a fixed hierarchy of signal words that the target language must match level for level. Render GEFAHR, WARNUNG and VORSICHT (literally danger, warning, caution) inconsistently or at the wrong level, and the stated risk changes.
Instructions must read as commands
German technical writers use infinitives such as ‘Schutzabdeckung entfernen’, literally ‘protective cover remove’. Several target languages need a different grammatical form so that the step reads as an instruction, not a description. In English it becomes ‘Remove the protective cover.’ A literal rendering creates ambiguity exactly where clarity is safety-relevant.
A tightening torque of 1,5 Nm must not read as 15 Nm
A German decimal comma left in an English manual makes a tightening torque of 1,5 Nm look like 15 Nm to anyone who reads the comma as a thousands separator. In English it reads 1.5 Nm.
Terminology drift comes from separate commissioning
The costliest error in technical documentation is rarely a wrong word. It is the same term changing from one document to the next. A component named differently in the manual, the spare parts catalogue and the training material causes service queries, wrong orders and, at worst, downtime for the customer.
The risk specific to technical documentation is terminology drift across separately commissioned documents; a client terminology database and translation memory prevent it.
Heavily inflected target languages make it worse, because a later global search and replace breaks the grammar. So do digital-only instructions under the new Regulation: the documentation in which the drift spreads keeps growing for a decade. Three measures prevent it.
- Fix the terminology before the first job instead of reconstructing it after the third.
- Lock the names that stay untranslated: product names, type designations, panel display texts. Translate display texts only if the firmware actually outputs the target language; otherwise the manual points to menu items the machine does not show.
- Run one translation memory across all documents of a product, not separate projects.
- 2021: the manual
Commissioned on its own and translated properly, with a defensible name for every component.
- 2023: the spare parts catalogue
Commissioned separately. Without a shared terminology base, a second translator makes a different, equally defensible choice.
- 2025: the training material
Commissioned again on its own. After three jobs there are three valid names for the same component.
Formats, translation memory, patents and language pairs
Which file formats can you work with?
Word and FrameMaker, as well as Excel, PowerPoint, Adobe PageMaker, QuarkXPress and AutoCAD, among others. In structured formats the markup is preserved, so the translation flows back into your system without manual rework. Name the format in your request, as it markedly affects effort and price.
How much does a translation memory save on follow-up jobs?
That depends on the share of repeated text. In technical documentation it is typically high, because safety instructions, maintenance intervals and component descriptions recur from one document to the next. Segments that have already been translated are reused from the translation memory, which lowers the price. Your repetition rate is calculated before the quote.
Do you also translate patent specifications?
Yes. Patent translation is a genre of its own, with highly formalised language and its own conventions for wording claims. The literal structure of the claims has to be kept, because it defines the scope of protection. Each patent office sets its own language and formal requirements for filing, so settle them before placing the order.
Which language pair is requested most often for technical translation?
German to English, because English serves as a bridge language for many export markets and international supplier documentation is kept in English. The same applies to French, Polish, Dutch, Spanish and Italian. For English, name the variant you need: British and American English differ in units of measurement and in technical vocabulary, for instance in tool names (spanner or wrench).

Send the file or a sample with the target language and purpose, and you will usually have a quote on the same working day.
