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) | 93 | 94
Sound power level | dB(A) | 101 | 102
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:
ah | m/s2 | 14.0 | 13.3
K | m/s2 | 1.5 | 1.5
Chiselling:
ah | m/s2 | 9.4 | –
K | m/s2 | 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 compare power tools. They may also be used for a preliminary estimation of vibration and noise emissions.

The stated vibration level and noise emission value represent the main applications of the power tool. However, if the power tool is used for other applications, with different accessories 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 operator from the effects of vibration, such as servicing the power tool and accessories, keeping their hands warm, and organising workflows correctly.
