Noise/Vibration Information
GBH12-52D GBH12-52DV
Noise emission values determined according to ENIEC62841-2-6.
Typically, the A-weighted noise level of the power tool is:
Sound pressure level dB(A) 96 96
Sound power level dB(A) 107 107
UncertaintyK dB 3 3
Wear hearing protection!
Vibration total values ah (triax vector sum) and uncertainty K determined according to ENIEC62841-2-6:
Hammer drilling into concrete:
ahm/s216.4 10.8
K m/s21.5 1.5
Chiselling:
ahm/s215.4 10.6
K m/s21.5 1.5
The vibration level and noise emission value given in these
instructions have been measured in accordance with a
standardised measuring procedure and may be used to com-
pare power tools. They may also be used for a preliminary
estimation of vibration and noise emissions.
The stated vibration level and noise emission value repres-
ent the main applications of the power tool. However, if the
power tool is used for other applications, with different ap-
plication tools or is poorly maintained, the vibration level
and noise emission value may differ. This may significantly
increase the vibration and noise emissions over the total
working period.
To estimate vibration and noise emissions accurately, the
times when the tool is switched off or when it is running but
not actually being used should also be taken into account.
This may significantly reduce vibration and noise emissions
over the total working period.
Implement additional safety measures to protect the oper-
ator from the effects of vibration, such as servicing the
