GBH 3-28 DRE/GBH 3-28 DFR:

The vibration level given in this information sheet has been 
measured in accordance with a standardised test given in 
EN 60745 and may be used to compare one tool with anoth-
er. It may be used for a preliminary assessment of exposure.
The declared vibration emission level represents the main 
applications of the tool. However if the tool is used for differ-
ent applications, with different accessories or insertion 
tools or is poorly maintained, the vibration emission may dif-

fer. This may significantly increase the exposure level over 
the total working period.
An estimation of the level of exposure to vibration should al-
so take into account the times when the tool is switched off 
or when it is running but not actually doing the job. This may 
significantly reduce the exposure level over the total work-
ing period.
Identify additional safety measures to protect the operator 
from the effects of vibration such as: maintain the tool and 
the accessories, keep the hands warm, organisation of work 
patterns.

Declaration of Conformity

We declare under our sole responsibility that the product de-
scribed under “Technical Data” is in conformity with the fol-
lowing standards or standardization documents: EN 60745 
according to the provisions of the directives 2011/65/EU, 
2004/108/EC, 2006/42/EC.
