Noise level
The values quoted are emission levels and are not necessarily safe working levels.
Although there is a correlation between emission and exposure levels, this cannot be used reliably to
determine whether or not additional precautions are required. Factors influencing the current exposure
level of the workforce include the characteristics of the working environment, other noise sources etc.,
i.e., the number of adjacent machines and other processes. In addition, the allowable exposure level
may vary according to country. However, this information allows the machine user to make a better
danger and risk assessment.
Since the sound pressure level (
L
PA
) can vary significantly depending on the type of environment (more
or less reverberant) in which the machine is installed, the sound power level (L
WA
) emitted by the
machine is given, which is an absolute figure independent of the environment.
Cardan models
The measured values of L
pA
e L
wa
are as follows:
Sound power during cutting operation L
WA
dB(A) = 108.5
Sound power, no-load operation L
WA
dB(A) = 108.0
Uncertainty assured K = 4 dB
Sound pressure L
PA
dB(A) at operator's workstation during cutting operation = 90.5
Sound pressure L
PA
dB(A) at operator's workstation, no-load operation = 89.5
Electric models
The measured values of L
pA
e L
wa
are as follows:
Sound power during cutting operation L
WA
dB(A) = 104.0
Sound power, no-load operation L
WA
dB(A) = 96.0
Uncertainty assured K = 0.2 - 3 dB
Sound pressure L
PA
dB(A) at operator's workstation during cutting operation = 88.5
Sound pressure L
PA
dB(A) at operator's workstation, no-load operation = 80.5
Regular maintenance of the machine and blades according to the instructions provided in the Use and
Maintenance Manual will keep noise emission levels low over time.
