Removing the Blade Frames 
   

WARNING

 

      

ALWAYS DISCONNECT THE SLICER FROM THE POWER SUPPLY BEFORE 

ATTEMPTING ANY TYPE OF MAINTENANCE TASK. 

 

Swing out the discharge table from the slicer.  See the next illustration.   
 

 
 
 
Always start by removing the discharge side blade frame first.  Both blade frames should 
be removed from the discharge side of the machine.   You should remove the discharge 
side blade frame completely from the machine before starting on the infeed side blade 
frame.  However each is removed using similar procedures.
