1. Handling, transport and storage
1.1 Handling
      Grinding wheels are fragile and  sensitive  to impacts  and  shocks. Be aware of  this  when you handle them.    
     
1.2 Transport
      The grinding wheels must be handled with care during transportation.
1.3 Storage
     Grinding wheels shall  be stored in such a manner that   mechanical damage is  avoided and that  they  are  not  subjected  to damaging  environment.
Store in dry ,  frost  free  conditions  in special  racks or containers.  Store in  moderate and  constant  temperature . Use the wheels  held  in stock
longest first.

2. Marking
    Use only wheels which are properly labeled.Read the marking and obey the instructions for use. Never  exceed   the  maximum operating speed of the wheel in RPM or /min.
¡¡
3. Inspection and tests before mounting
    Make sure that the instructions on the wheel and on the machine are compatable.
3.1 Visual inspection
    Carefully inspect the abrasive wheels: if they are damaged in any way do not use them.
3.2 Test run
    Before use each wheel  must  be run up to its  maximum operating speed on the  machine under
no load conditions for about 30 seconds.  Before starting  the test run  the wheel  guard must be in place. Never use damaged or imperfect  wheels, destroy them.
3.3 Safety equipment
    Before starting the cutting-off  or grinding operation, the wheel guard  must be  in  position  and fixed securely.

4. Mounting of  the grinding wheels, fixation  of  the   mounting  devices  Only mount the wheels on  machines designed   for the  operation . Never use force for
mounting . Always  use  the  mounting  flanges  supplied  with  the  machine and  insure  they  are clean, never  modify  them  in  any  case.  Always use blotters when they are supplied with  the  wheels. Work pieces shall be firmly secured before grinding  commences. Instructions  for  use : Grind  and  cut  only  materials  for  which  the 
grinding  wheel is suitable. Cutting off : keep the wheel straight in the cut. Grinding :keep the wheel 
at an angle of 20-30 degrees with the piece.

    Hand held grinders should  be used in such a  manner that   sparks fly away from  the operator's  body  or any   flammable
material.
5.4 Safety guards
    The wheel guard of the machine must be in position and securely fixed.
5.5 Stopping the machine
    Switch off the machine and allows the wheel  to stop completely   before  placing  it on a  bench
or on the floor.

6. Safety pictograms
    This pictogram may appear on posters,in brochures,on packaging,on machines and on grinding wheels or their labels
