Emissions
The airborne noise of the geared drill is 75 to 80 dB (A) at the operator position and operating
conditions in accordance with DIN ISO 8525
If the geared drill is installed in an area where various machines are in operation, the noise
exposure (immission) on the operator of the geared drill at the working place may exceed 80
dB(A).
INFORMATION
This numerical value was measured on a new machine under the operating conditions specified
by the manufacturer. The noise behaviour of the machine might change depending on the age
and wear of the machine.
Furthermore, the noise emission also depends on production engineering factors, e.g. speed,
material and clamping conditions.
INFORMATION
The specified numerical value represents the emission level and does not necessarily a safe
working level.
