Protection class
The values given are valid for nominal voltages [U] of 230/
240 V. For lower voltages and models for specific coun-
tries, these values can vary.
Please observe the article number on the type plate of your
machine. The trade names of the individual machines may
vary.
Noise/Vibration Information
Measured values determined according to
EN 60 745.
Typically the A-weighted noise levels of the ma-
chine are: sound pressure level 96 dB (A); sound
power level 107 dB (A). Uncertainty K = 3 dB.
Wear hearing protection!
Vibration total values (triax vector sum) deter-
mined according to EN 60 745:
Drilling into metal: Vibration emission value a

2.5 m/s , Uncertainty K=1.5 m/s
Impact drilling into concrete: Vibration emission

The vibration emission level
WARNING
given in this information sheet
has been measured in accordance with a stand-
ardised 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 infor-
mation sheet. This could lead to a significant un-
derestimate of exposure 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 ac-
count 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.
