The vibration emission level given in this
information 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.
WARNING:
The declared vibration emission level
represents the main applications of the
tool. However, if the tool is used for
different applications, with different
accessories or poorly maintained, the
vibration emission may differ. This may
signi cantly increase the exposure level
over the total working period.
An estimation of the level of exposure
to vibration should also take into
account the times when the tool is
switched off or when it is running but
not actually doing the job. This may
signi cantly 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.
De nitions: Safety guidelines
The de nitions below describe the level of severity
for each signal word. Please read the manual and
pay attention to these symbols.
DANGER: Indicates an imminently
hazardous situation which, if not
avoided, will result in death or serious
injury.
WARNING: Indicates a potentially
hazardous situation which, if not
avoided, could result in death or serious
injury.
