Wear ear protection.NOTE: The declared noise emission value(s) has been measured in accordance with a standard test method andmay be used for comparing one tool with another.NOTE: The declared noise emission value(s) may also be used in a preliminary assessment of exposure.WARNING: Wear ear protection.WARNING: The noise emission during actual use of the power tool can differ from the declared val-ue(s) depending on the ways in which the tool is used especially what kind of workpiece is processed.WARNING: Be sure to identify safety measures to protect the operator that are based on an estimationof exposure in the actual conditions of use (taking account of all parts of the operating cycle such as thetimes when the tool is switched off and when it is running idle in addition to the trigger time).
