Noise Information
Noise characteristic values in accordance with EN 792-
13, JUNE, 2000:
The typical A-weighted single-event sound power level
The typical A-weighted single-event emission sound
pressure level at work station
These values are tool-related characteristic values and
do not represent the noise development at the point of
use. Noise development at the point of use will for
example depend on the working environment, the
workpiece, the workpiece support and the number of
driving operations, etc.
Depending on the conditions at the workplace and the form
of the workpiece, individual noise attenuation measures
may need to be carried out, such as placing workpieces
on sound-damping supports, preventing workpiece
vibration by means of clamping or covering, etc.
In special cases it is necessary to wear hearing protection
equipment.
