Noise Value and Vibration
Test result
Noise emission values determined according to EN 62841 - 1 :
Wear hearing protection while operating the power tool.
Warning:
The declared vibration total value(s) and the declared noise emission
value(s) have been measured in accordance with a standard test
method and may be used for comparing one tool with another.
The declared vibration total value(s) and the declared noise emission
value(s) may also be used in a preliminary assessment of exposure.
The vibration emission and noise emissions during actual use of the
power tool can differ from the declared total value depending on the
ways in which the tool is used.
There is the need 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).
