NOTE: The declared vibration emission value has been measured in accordance with the standard test method
and may be used for comparing one tool with another.
NOTE: The declared vibration emission value may also be used in a preliminary assessment of exposure.

 WARNING: The vibration emission during actual use of the power tool can differ from the declared emission
value depending on the ways in which the tool is used.
WARNING: Be sure 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).
WARNING: The declared vibration emission value is used for main applications of the power tool. However if
the power tool is used for other applications, the vibration emission value may be different.
