4.3 Noise information and vibration values in accordance with EN 60745
The sound pressure and vibration values given in these instructions were measured in accordance with a
standardized test and can be used to compare one power tool with another. They can also be used for a
preliminary assessment of exposure. The data given represents the main applications of the power tool.
However, if the power tool is used for different applications, with different accessory tools, or is poorly
maintained, the data can vary. This can significantly increase exposure over the total working period. An
accurate estimation of exposure should also take into account the times when the tool is switched off, or
when it is running but not actually being used for a job. This can significantly reduce exposure over the
total working period. Identify additional safety measures to protect the operator from the effects of noise
and/or vibration, for example: Maintaining the power tool and accessory tools, keeping the hands warm,
organization of work patterns.
