The vibration values quoted above have been
measured according to a standardized test pro‐
cedure and may be used to compare electric
power tools. Depending on the type of usage,
the vibrations that actually occur may differ from
the values quoted. The vibration values quoted
may be used for an initial assessment of the
user's exposure to vibrations. The actual expo‐
sure to vibrations has to be estimated. This proc‐
ess may also take into account times during
which the electric power tool is switched off and
times during which it is switched on but running
off load.

REACH is an EC regulation and stands for the
Registration, Evaluation, Authorisation and
Restriction of Chemical substances.
