Noise Information
(EN 12549:1999)
LpA, 1s, d 93 dB
Uncertainty 0.51 dB
LwA, 1s, d 102 dB
Uncertainty 0.62 dB
These values are tool-related characteristic values and do not represent noise generation at the point of use. Noise at
the point of use will for example depend on the working environment, the working piece, the workpiece support, and the
number of driving operation. Workplace design can also serve to reduce noise levels, for example placing workpiece on
sound-damping supports.
Vibration Information
(ISO 8662-11:1999)
Vibration 3.6 m/s2
uncertainty 0.20 m/s2
This value is a tool-related characteristic value and does not represent the influence to the hand-arm-system when using
the tool. Any influence 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 workpiece support.
2. SAFETY WARNINGS
