Vibration total values (triax vector sum) determined according to EN60745:
Vibration
emission value m/s²
Uncertainty K m/s²
The declared vibration emission value has been
measured in accordance with a standard test
method and may be used for comparing one tool
with another.
The declared vibration emission value may also be
used in a preliminary assessment of exposure.
WARNING: The vibration emission
value during actual use of the power
tool can differ from the declared value
depending on the ways in which the tool
is used. This could lead to a significant
underestimate of exposure when the
tool is used regularly in such a way.
An estimation of the level of exposure to vibration
experienced during a given period of work should
also take into account the times when the tool is
switched off and when it is running idle in addition to
the trigger time.
This may significantly reduce the exposure level over
the total working period.
