Due  to  different  working  conditions  it  can’t  be  foreseen  how  frequently  inspections  for  wear  check’s, 

inspection,  maintenance  and  repair  works  ought  to  be  carried  out.  Prepare  a  suitable  inspection  schedule 
considering your own working conditions and experience. 
 
Pay attention to unusual noises or strong vibrations. Check for the cause of every big change. Call a technician 
if you have doubts about the cause or when a repair without a technician seems not possible without damages. 
Only use genuine Blastrac spare parts. 
 
After use, clean the machine with the dust collector, so there is no dust on the machine. 
See to it that any wastes or fibre residues do not remain in the machine. 
 
 

Our specialists will be happy to assist you with more advice. 

 

 

Prior to any repair works on the machine and its drives, secure the  machine against unintentional

heat, dust and shocks. Remove the abrasive out of the abrasive storage hopper. 
 
All repair work must to be done by qualified Blastrac personnel, this to guarantee a safe and reliable machine.
