VIbRATION
The European Physical Agents (Vibration) Directive sets out minimum requirements
applying across Europe for prevention of risk from vibration including hand arm vi-
bration syndrome injuries to power tool users. Indicative vibration test results quoted
below enable users to make informed decisions as to the period of time a power tool
can be used safely on a daily basis and the choice of tool.

Vibration total values (triax vector sum) determined according to EN 60745:
Work mode description 1
(if required by the relevant Part 2)
Hammer drilling in concrete
Vibration emission value a
h,HD
= 13,5 m/s
2
Uncertainty K
KHD
= 1,5 m/s
2
Work mode description 2
(if required by the relevant Part 2)
Hammering
Vibration emission value a
h,CHeq
= 11,5 m/s
2
Uncertainty K
CHeq
= 1,5 m/s
2
The declared vibration emission been measured in accordance with a standardised
test stated above and may be used to compare one tool with another
The declared vibration emission value may also be used in a preliminary assessment
of exposure.
Calculating the actual period of use can be difficult and the HSE website has a spread-
sheet to help calculate exposures from multiple tool use, to help establish the need to
limit the duration of tool use, etc.
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 of the correct accessory for the tool and ensuring it is sharp and in good
condition.
- The tightness of the grip on the handles.
- 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:
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).
