The vibration emission level given in this information sheet has
been measured in accordance with a standardised test given in
EN60745 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 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

This may significantly 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.
