Vigtige sikkerhedsoplysninger
Always follow safety precautions when operating the generator. Failure to do so can result in serious injury or death.

- Varme overflader: The generator's engine and muffler become hot during operation. Avoid contact with hot surfaces to prevent burns. Allow the generator to cool before handling or storing.
- Bevægelige dele: Hold hænder, fødder og tøj væk fra bevægelige dele.
