The vibration emission level stated at the back of this 
instruction manual has been measured in accordance 
with a standardised test given in EN 60745; it may be 
used to compare one tool with another and as a 
preliminary assessment of exposure to vibration when 
using the tool for the applications mentioned
-  using the tool for different applications, or with 

different or poorly maintainted accessories, may 
signifi cantly 

increase

 the exposure level

-  the times when the tool is switched off or when it is 

running but not actually doing the job, may 
signifi cantly 

reduce

 the exposure level

!  protect yourself against the effects of vibration by 

maintaining the tool and its accessories, keeping 
your hands warm, and organizing your work 
patterns
