The vibration emission level given in this infor-
mation sheet has been measured in accordance
with a standardised test given in EN 60745 and
may be used to compare one tool with another.
It may be used for a preliminary assessment of
exposure.
The declared vibration emission level represents
the main applications of the tool. However if the
tool is used for different applications, with differ-
ent accessories or poorly maintained, the vibra-
tion emission may differ. This may significantly
increase the exposure level over the total work-
ing period.
An estimation of the level of exposure to vibra-
tion should also take into account the times
when the tool is switched off or when it is run-
ning but not actually doing the job. This may sig-
nificantly reduce the exposure level over the total
working period.
Identify additional safety measures to protect
the operator from the effects of vibration such
as: maintain the tool and the accessories, keep
the hands warm, organisation of work patterns.
