Warning:  Engine, exhaust system and hydraulic component temperatures could 
be in excess of 200 

F causing severe burns if touched.

 

 

 
Pay attention to Chapter 3 

"Safety"

 during maintenance and repair works.  

 
Failures due to inadequate or incorrect maintenance may generate very 

high repair costs

 and long downtimes of 

the BMR-75D. 

Regular

 maintenance, therefore, is imperative. 

 
Operational safety and service life of the shot blaster depend, among other things, on proper maintenance. 
 
The following table shows recommendations about time, inspection, and maintenance for the normal use of the shot 
blaster. 
 

 

Operating hours/ 

time period 

Inspection points, maintenance instructions 

12 h after repairing 

Check all accessible screw connections for tight seat. 

Daily and prior to 
starting work 

Check all safety devices working adequate. 
Check the function of the residual current operated device.  
Check the hose connections for tightness and fixed seat

Check the electric connections for sediments of dirt or foreign bodies. 
Grease all the grease zerks on the bearings 
Rotate the pinch bar 

Annually 

Full overhaul and cleaning of the complete machine. 

 
 
The  time  indications  are  based  on  uninterrupted  operation.  When  the  indicated  number  of  working  hours  is  not 
achieved during the corresponding period, the period can be extended. However a full overhaul must be carried out 
at least once a year. 
 

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

ecks,  inspection, 

maintenance, and repair work ought to be carried out. Prepare a suitable inspection schedule considering your own 
working conditions and experience. 
 
Our specialists will be happy to assist you with more advice.
