Noise level*
*
: L shows the sound power level under the ISO3744 satisfied test conditions.
WA
The noise level in "dB (A) / 7 m" is the arithmetic mean value in four directions measured 7
meters away from each side of the generator.
The noise level may vary in different environments.
"The figures quoted are emission levels and are not necessarily safe working levels.
Whilst there is a correlation between the emission and exposure levels, this cannot be
used reliably to determine whether or not further precautions are required. Factors that
influence the actual level of exposure of work-force include the characteristics of the
work room, the other sources of noise, etc. i.e. the number of machines and other adja-
cent processes, and the length of time for which an operator is exposed to the noise.
Also the permissible exposure level can vary from country. This information, however,
will enable the user of the machine to make a better evaluation of the hazard and risk."
