2.10 Emissions
The noise level (emission) of the mill drill machine is below 76 dB(A). If the mill drill machine is
installed in an area where various machines are in operation, the acoustic influence (immission)
on the operator of the mill drill machine may exceed 85 dB(A).
INFORMATION
This numeric value had been measured on a new machine under conventional operating condi-
tions. Depending on the age or wear of the machine, the noise behavior of the machine might
change.
Furthermore, the extent of the noise emission is also depending on manufacturing
influence factors, such as speed, material and clamping conditions.
INFORMATION
The mentioned numerical value is an emission level and not necessarily a safe
working level.
Unless the degree of noise emission and the degree of noise disturbance are depending on one
another it is not possible to use it in order to reliably determine if it is necessary to take further
preventive measures or not.
The following factors influence the actual degree of the noise disturbance of the
operator:
•Characteristics of the working chamber, e.g. size or damping behavior,
• Other noise sources, e.g. the number of machines,
• Other processes proceeding nearby and the period during which the operator is exposed to
the noise.
Consult OSHA, state and local regulations in order to determine compliance, dangers and risks
to the operator.
CAUTION!
The machine operator has to wear an appropriate ear protection depending on the overall
stress caused by noise and on the basic limit values.
We generally recommend using a sound and ear protection.
