1.9 Vibration and noise
Warning!
Always use ear muffs when using the machine.
1.9.1 Hand and arm vibrations
Hand and arm weighted vibration level [m/s²] for FGE530P FGE450P FGE400P
FGE270P have been measured with equipment approved according to ISO
5349-1:2001. The measurement uncertainty for the measurement apparatus has been
measured as +/- 2%.
The machine has been tested in accordance with ISO 5349-2:2001 and ISO 20643:2005
in order to identify the operations that contribute to the most frequent vibration
exposures. At vibration levels > 2.5 m/s², the exposure time should be limited in
accordance with the table below. For vibration levels > 5 m/s², immediate measures
should be taken by the employer to ensure that the exposure time does not exceed the
time specified in the table below.
