Emissions
The emission of the drilling machine is below 76 dB(A).
If the is installed in an area where various machines are in operation the acoustic influence
immission) on the operator of the drilling machine may exceed 85 dB(A).
INFORMATION
This numerical value was measured on a new machine under proper operating conditions.
Depending on the age respectively on the wear of the machine it is possible that the noise
behaviour of the machine changes.
Furthermore, the factor of the noise emission is also depending on manufacturing influencing
factors, e.g. speed, material and clamping conditions.
INFORMATION
The mentioned numerical value is the emission level and not necessarily a safe working level.
Though there is a dependency between the degree of the noise emission and the degree of the
noise disturbance it is not possible to use it reliably to determine if further precaution measures
are required or not.
The following factors influence the actual degree of the noise exposure of the operator:
Characteristics of the working area, e.g. size or damping behaviour
,
Other noise sources, e.g. the number of machines,
Other processes taking place in the proximity and the period of time during which the oper-
ator is exposed to the noise.
Furthermore, it is possible that the admissible exposure level might be different from country to
country due to national regulations.
This information about the noise emission shall allow the operator of the machine to more eas-
ily evaluate the endangering and risks.
CAUTION!
Depending on the overall noise exposure and the basic limit values the machine
operators must wear an appropriate hearing protection.
We generally recommend to use a noise protection and a hearing protection.
