33 WZ Bedien-1611_(24) :24 Seite 33 Noise and vibration information Noise and vibration information The specified noise and vibration levels were determined in accordance with the standards EN , EN and EN The specified vibration emission level was measured on the basis of a standardised test procedure and can be used to compare power tools with one another. The specified vibration emission value may also be used to initially assess the impairment. The declared values are noise emission values and therefore do not necessarily represent safe values for the workplace at the same time. The correlation between emission and immission levels cannot reliably provide for a conclusion as to whether additional cautionary measures are necessary or not. Factors that could affect the respective imission level present at the workplace involve the specification of the work area, the surrounding area, the duration of exposure, other noise sources etc. You must also observe any divergences in national regulations with respect to permissible workplace levels. The aforementioned information does, however, allow the user to better assess dangers and risks. CAUTION! Risk of injury due to vibrations! While actually using the power tool, the vibration emission value may differ from the specified value depending on how the power tool is used. Define safety precautions to protect the user in relation to actual conditions of use. All parts of the operating cycle must be accounted for, i.e. including periods during which the power tool is switched off and during which it is turned on, but not operating under load. Wear protective gloves and take work breaks as necessary to reduce the risks posed by vibration. 33
