Noise Information
Noise characteristic values in accordance with EN 792-13:
The typical A-weighted single-event sound power level
The typical A-weighted single-event emission sound
pressure level at work station
Uncertainty KpA: 3 dB
These values are tool-related characteristic values and
do not represent the noise development at the point of
use. Noise development at the point of use will for example
depend on the working environment, the workpiece, the
workpiece support and the number of driving operations,
etc.
Depending on the conditions at the workplace and the form
of the workpiece, individual noise attenuation measures
may need to be carried out, such as placing workpieces on
sound-damping supports, preventing workpiece vibration by
means of clamping or covering, etc.
In special cases it is necessary to wear hearing protection
equipment.
Vibration Information
The typical vibration characteristic value in accordance with
EN 792-13: 4.6 m/s
2
Uncertainty K = 1.5 m/s
2
This values is a tool-related characteristic value and
does not represent the infl uence to the hand-arm-system
when using the tool. An infl uence to the hand-arm-system
when using the tool will for example depend on the gripping
force, the contact pressure force, the working direction, the
adjustment of energy supply, the workpiece, the wrokpiece
support.
The declared vibration total value has been measured in
accordance with a standard test method and may be used
for comparing one tool with another.
It may also be used in a preliminary assessment of exposure.
WARNING
○ The vibration emission during actual use of the power
tool can diff er from the declared total value depending in
the ways in which the tool is used.
○ Identify safety measures to protect the operator that are
based on an estimation of exposure in the actual conditions
of use (taking account of all parts of the operating cycle
such as the times when the tool is switched off and when
it is running idle in addition to the trigger time).
