Information for users of above mentioned machinery, requested by directives: 2003/10/ES – exposure of operators to noise and 
2002/44/ES – exposure of operators to vibrations (czech equivalent NV no. 272/2011 Sb.): 
With regard to declared acoustic pressure value A at working place of the operator and to declared aggregate value of hand-arm 
vibrations transferred to the operator it is necessary to use protective equipment effective against above mentioned noise value 
and hand-arm vibrations when operating the particular type of the floor saws and further it is necessary to modify the working 
processes because of setting technological breaks due to reduce the exposure of the operator to the hand-arm vibrations.

 

Exposure can be mutually proportional to the mass operator.

 

 
ATTENTION! 
The  noise  emission  measurements  obtained  in  accordance  with  the  European  standards  do  not  necessarily  correspond  with 
varying levels of noise produced under process 
real conditions of use. Measurements are made when the machine is running on empty - no load. 
 
In case of casting machines suitable blade can also cut dry. Due to an increased incidence of dust, but in this case you must use 
protective equipment for respiratory protection (respirator).
