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.
Further Advice on managing risks from vibration can be found at 
www.hse.gov.uk/vibration

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).
