Emission values for sound (Two-figure – specifications as per ISO 4871)
Sound emission

REMARK: The sum of the measured emission value and respective measuring inaccuracy
represents the upper limit of the values that can occur during measuring.
Wear hearing protection!
Measured values determined in accordance with the corresponding product standard.
Extension cable.
If the use of an extension cord
WARNING
is required, its length and con-
ductor cross-section must be adequate for the
application in order to prevent a voltage drop
in the extension cord, power loss and over-
heating of the power tool. Otherwise, the
extension cable and power tool are prone to
electrical danger, and the working efficiency is
decreased.
Intended use of the power tool:
Magnetic base drill for drilling with annular
cutting tools on ferrous materials in con-
trolled environments using the cutting tools
and accessories recommended by the manu-
facturer.
Operation of the power tool off power generators.
This power tool is also suitable for use
with AC generators with sufficient power
output that correspond to the Standard
ISO 8528, design type G2. This Standard is
particularly not complied with when the so-
called distortion factor exceeds 10 %. When
in doubt, please refer to the generator
instruction/specification guide.
