-NOTE-
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 assess-
ment of exposure. 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 significantly 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 significantly reduce the exposure level over the total working peri-
od. 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.
Noise and vibration information (according to EN 60745):
Typical A-weighted noise pressure level: < 70 dB (A)
For the given sound power level as per EN 60745, the tolerance is 3 dB.
