Sikkerhedsinstruktioner

- Bær øjenbeskyttelse: Bær altid sikkerhedsbriller eller beskyttelsesbriller.

- Overdriv ikke: Oprethold korrekt fodfæste og balance til enhver tid.
- Afbryd strømmen: Unplug the sander from the power source before making any adjustments, changing accessories, or storing the tool.
- Brug det rigtige værktøj: Tving ikke små værktøjer eller tilbehør til at udføre arbejdet som et kraftigt værktøj.
