Noise/Vibration Information
Measured values determined according to EN 60745.
Typically the A-weighted noise levels of the product
are: Sound pressure level 91 dB(A); Sound power
level 102 dB(A). Uncertainty K =2 dB.
Wear hearing protection!
Vibration total values (triax vector sum) determined
according to EN 60745:
Hammer drilling into concrete: Vibration emission

=15 m/s

.
The vibration emission level given in
this information sheet has been
measured in accordance with a standardised test
given in EN 60745 and may be used to compare one
tool with another.
The vibration emission level will vary because of the
ways in which a power tool can be used and may
increase above the level given in this information sheet.
This could lead to a significant underestimate of expo-
sure when the tool is used regularly in such a way.
Note:
To be accurate, an estimation of the level of
exposure to vibration experienced during a given
period of work should also take into account the times
when the tool is switched off and when it is running but
not actually doing the job. This may significantly
reduce the exposure level over the total working
period.
