Noise/Vibration Information
Noise emission values determined according to EN IEC 62841-2-3.
Typically the A-weighted noise level of the power tool are: 89 dB(A); sound power level 97 dB(A). Uncertainty K = 3 dB.
Wear hearing protection!
Vibration total values ah (triax vector sum) and uncertainty K determined according to EN IEC 62841-2-3:
Surface grinding (roughing):
ah = 10.0 m/s2, K = 1.5 m/s2,
Disc sanding:
ah = 4.0 m/s2, K = 1.5 m/s2,
Cut-off grinding:
ah = 7.5 m/s2, K = 1.5 m/s2.
Grinding thin metal sheets or other materials that tend to easily vibrate with a large surface area can cause the noise emission value to increase by up to 15 dB. Suitable, heavy damping mats can reduce the increased noise emissions. Increased noise emissions must be taken into consideration, both for the risk assessment of the noise output and for selecting suitable hearing protection.
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 application 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 operator from the effects of vibration, such as servicing the power tool and application tools, keeping their hands warm, and organising workflows correctly.
