The following information:
• that the declared vibration total value has been measured in
accordance with a standard test method and may be used for
comparing one tool with another;
• that the declared vibration total value may also be used in a
preliminary assessment of exposure.
Warning:
that the vibration emission during actual use of the power tool can differ
from the declared total value depending on the ways in which the tool is
used; and of the need to identify safety measures to protect the operator
that are based on an estimation of exposure in the actual conditions of
use (taking account of all parts of the operating cycle such as the times
when the tool is switched off and when it is running idle in addition to
the trigger time) .
