NOTE: The declared noise emission value(s) has been measured in accordance with a standard test method and
may 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 estimation
of exposure in the actual conditions of use (taking account of all parts of the operating cycle such as the
times when the tool is switched off and when it is running idle in addition to the trigger time).
WARNING: Grinding thin sheets of metal or other easily vibrating structures with a large surface can
result in a total noise emission much higher (up to 15 dB) than the declared noise emission values.
Set heavy flexible damping mats or such to those workpieces to prevent them from emitting sound.
Take the increased noise emission into consideration for both the risk assessment of noise exposure and
selecting adequate hearing protection.
