Note:
To keep the noise emission as low as possible, always use sharpened tools and operate the machine at the
correct speed.
Ear protection must always be worn; however, such protection cannot be considered a substitute for properly
sharpened tools.
All values in dB(A) and with a measurement uncertainty factor of 4 dB(A).

3.7 Noise emission
The specified values are emission values and therefore
do not represent safe workplace values. Even though a
relationship exists between particle emission and noise
emission levels, an inference cannot be made about
whether additional safety measures need to be imple-
mented. Factors which can significantly affect the emis-
sion level that presently exists at the workplace include
duration of the effect, characteristics of the workspace,
and other ambient influences. The permissible workplace
values may also differ from country to country. Neverthe-
less, this information is provided to help the operator bet-
ter assess hazards and risks. Depending on the location
of the machine and other specific conditions, the actual
noise emission values may deviate significantly from the
specified values.
Specifications
3.6 Particle emission
The working areas of this machine comply to BGI 739-1
and are classed as dust reduced.
The maximum concentration level of 2 mg/m³ of inhala-
ble dust in the air will not be exceeded.
This only applies if the conditions that are specified in
the section >Extraction< are adhered to.
See chapter entitled >Setup and installation<
