Vibration and noise emission values.
power tool, hand/arm vibra-
tions occur.
These can lead to health impair-
ments.
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.
It is necessary to identify
safety measures to protect
the operator that are based on an estimation
of exposure in the actual conditions of use.
The vibration and noise emission values
given in these instructions have been mea-
sured according to a measurement method
standardized in EN 62841 and can be used
to compare power tools with each other.
They are also suitable for a preliminary
assessment of vibration and noise exposure.
The given vibration and noise emission
values represent the main applications
of the power tool.
However, if the power tool is used for other
applications, with deviating application tools
or insufficient maintenance, the overall
vibration values and the noise emission val-
ues may differ. This can significantly increase
the vibration and noise exposure over the
total working period.
For an accurate estimation of vibration and
noise exposure, the durations when the
equipment is switched off or running but
not actually in use should also be taken into
account. This may significantly reduce the
vibration and noise exposure over the total
working period.
Identify additional safety measures to
protect the operator from the effects of
vibration and noise such as: Maintaining the
power tool and accessories, keeping the
hands warm, organization of work patterns.
