Noise emission values
The saw’s noise is measured in accordance with
DIN EN ISO 3744; 11/95, E DIN EN 31201; 6/93,
ISO 7960 Annex A; 2/95. The machine may
exceed 85 dB(A) at the workplace. In this case,
noise protection measures need to be introduced
for the user (ear-muffs).
Cutting Idling
Sound pressure level LPA 105.0 dB(A) 85.0 dB(A)
Sound power level LWA 114.6 dB(A) 94.6 dB(A)
„The quoted values are emission values and not
necessarily reliable workplace values. Although there
is a correlation between emission and immission
levels it is impossible to draw any certain conclusions
as to the need for additional precautions. Factors
with a potential influence on the actual immission
level at the workplace include the duration of impact,
the type of room, and other sources of noise etc.,
e.g. the number of machines and other neighboring
operations. Reliable workplace values may also vary
from country to country. With this information the
user should at least be able to make a better
assessment of the dangers and risks involved.“
