Noise/vibration information
Noise emission values determined according to
EN 62841-2-5.
Typically, the A-weighted noise level of the power tool is:
Sound pressure level 97 dB(A); sound power level
108 dB(A). Uncertainty K = 3 dB.

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-
