VIBRATION INFORMATION
Vibration total values (triax vector sum) determined according to EN 60745:
Hammer drilling into concrete
Chiselling
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.
