 Take appropriate measures for the protection of hearing.

The sound levels stated are emission levels; they are not necessarily safe working 
levels. Even though the measured values are related to exposure levels, this 
information does not allow to determine if additional measures are required.
Factors that can affect the radiated levels are duration of exposure, the 
characteristics of the work area and other sound sources, as well as the number of 
machines of the same type or other machines in the work area.
The acceptable exposure levels may differ according to the country of use.
This information is only intended to help the user assess possible risks.
