2.1 Emissions
CAUTION!
Depending on the overall noise exposure and the basic threshold values, machine
operators must wear appropriate hearing protection.
We generally recommend the use of noise and ear protection.
The A-weighted sound pressure level L
pA
is 73 to 75 dB.
The A-weighted sound power level L
WA
is 98 to 102 dB.
INFORMATION
This numerical value was measured on a new machine under the operating conditions specified
by the manufacturer. The noise behaviour of the machine might change depending on the age
and wear of the machine.
Furthermore, the noise emission also depends on production engineering factors, e.g. speed,
material and clamping conditions.
INFORMATION
The following factors influence the actual degree of the noise exposure of the operator:
 Characteristics of the working area, e.g. size of damping behaviour,
 other noise sources, e.g. the number of machines,
 other processes taking place in proximity and the period of time, during which the operator
is exposed to the noise.
Furthermore, it is possible that the admissible exposure level might be different from country to
country due to national regulations.
