WARNING: Excessively high dust concentration during grinding work

    • Remove any grinding dust using the relevant vacuum cleaner approved for use on the material.
    • Remove dust in the work area regularly
    • Do not use compressed air to blow away dust deposits.
    • Always separate the dust from different materials [separate aluminium, steel and carbon fibre-reinforced plastic).
    • Clean the extraction system at regular intervals.
    • Never weld and grind in the same room at the same time.
    • Only use pneumatic grinders if possible.
