Charging The Battery - Hilti SF 4-A22 Manual De Instrucciones

4.4 Noise information and vibration values in accordance with EN
62841
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.
preliminary assessment of exposure.
The data given represent 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.
