VIBRATION INFORMATION
Vibration total values (triax vector sum) determined 
according to EN 60745:
Vibration 
emission value:
a
h
 = 3.633m/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
The use the correct accessory for the tool and ensuring 
it is sharp and in good condition.
The tightness of the grip on the handles and if any anti 
vibration accessories are used.
And the tool is being used as intended by its design 
and these instructions.
This tool may cause hand-arm vibration 
syndrome if its use is not adequately managed.
WARNING: To be accurate, an estimation of 
exposure level in the actual conditions of use 
should also take account of all parts of the operating 
cycle such as the times when the tool is switched off 
and when it is running idle but not actually doing the 
job. This may significantly reduce the exposure level 
over the total working period.
Helping to minimise your vibration exposure risk.
ALWAYS use sharp chisels, drills and blades
Maintain this tool in accordance with these instructions 
and keep well lubricated (where appropriate)
If the tool is to be used regularly then invest in anti 
vibration accessories.
Plan your work schedule to spread any high vibration 
tool use across a number of days.
