VIBRATION INFORMATION
Vibration total values (triax vector sum) determined according to EN 60745:
Typical weighted vibration
Vibration emission value: a
h
= 9,457m/s
2
Uncertainty K = 1.5m/s²
The declared vibration total value may be used for comparing one tool with another, and may also be
used in a preliminary assessment of exposure.
Warning: The vibration emission value during actual use of the power tool can differ from the
declared value depending on the ways in which the tool is used dependant on the following examples
and other variations on how the tool is used:
How the tool is used and the materials being cut or drilled.
The tool being in good condition and well maintained
