  • Legal information Warning notice system

    This manual contains notices you have to observe in order to ensure your personal safety, as well as to prevent damage to property. The notices referring to your personal safety are highlighted in the manual by a safety alert symbol, notices referring only to property damage have no safety alert symbol. These notices shown below are graded according to the degree of danger.

    DANGER indicates that death or severe personal injury will result if proper precautions are not taken.

    WARNING indicates that death or severe personal injury may result if proper precautions are not taken.

    CAUTION indicates that minor personal injury can result if proper precautions are not taken.

    NOTICE indicates that property damage can result if proper precautions are not taken. If more than one degree of danger is present, the warning notice representing the highest degree of danger will be used. A notice warning of injury to persons with a safety alert symbol may also include a warning relating to property damage.
