Typically the A-weighted noise levels of the
product are: Sound pressure level 91 dB(A);
Sound power level 102 dB(A). Uncertainty
K =3 dB.

Vibration total values (triax vector sum) deter-
mined according to EN 60745:
Hammer drilling into concrete: Vibrational emis-
sion value a =15 m/s
h
Chiselling: Vibrational emission value

a =12 m/s , uncertainty K=1.5 m/s
h
Drilling in metal: Vibrational emission value

Screwdriving without impact: Vibrational emis-
sion value a <2.5 m/s

The vibration emission level given in this infor-
mation sheet has been measured in accordance
with a standardised test given in EN 60745 and
may be used to compare one tool with another.
It may be used for a preliminary assessment of
exposure.
The declared vibration emission level repre-
sents the main applications of the tool. However
if the tool is used for different applications, with
different accessories or poorly maintained, the
