4.2 Noise information and vibration values determined in accordance with EN 60745
The sound pressure and vibration values given in these instructions have been measured in accordance with
a standardized test and may be used to compare one power tool with another.
The data given represents the main applications of the electric tool. However, if the electric tool is used for
different applications, with different accessory tools, or is poorly maintained, the data may vary. This may
significantly increase exposure over the total working period.
An accurate estimation of exposure should also take into account the times when the power tool is switched
off, or when it is running but not actually being used for a job. This may 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.
