Technical Data
Noise/Vibration Information
Measured values determined according to EN 60745.
Typically the A-weighted noise level of the machine is:
sound pressure level 86 dB(A); sound power level
97 dB(A). Uncertainty K=3 dB.
Wear hearing protection!
Overall vibrational values (vector sum of three direc-
tions) determined according to EN 60745:
Drilling in metal: Vibrational emission value
a
h
=2.5 m/s

, uncertainty K=1.0 m/s

.
The vibration emission level given in
this information sheet has been meas-
ured 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.

uct is in conformity with the following standards or
standardization documents: EN 60745 according to
