i.e. the motor may be run at the nominal capacity for 4 minutes and afterwards must run idle for 6 minutes.
4.4 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. Nevertheless, this information is provi-
ded to help the operator better 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.
It is recommended to use protective ear equipment, this is
however not a substitute for properly sharpened tools or
the correct operating speed.
An allowance must be made to compensate for tole-
rances with the specified emission values K = 4 dB (A).
Emission values at the workplace according to EN ISO 11202
Idle 83,1 db
Working 82,8 db
4.5 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 is certified by the blue label “BG Wood Particle
Tested”.
This only applies if the conditions that are specified in
the section >Extraction< are adhered to.
