A  variety  of  sections  can  be  cropped  at  this  aperture  -  round  and  square  sections,  unequal 
angle, channel, joist etc. 
Blades  for  round  and  square  section  cropping  are  fitted  as  standard  equipment  and  have 
apertures  of  varying  sizes.  The  smallest  aperture  should  be  chosen,  which  will  accept  the 
material, thus ensuring a complete and well supported cut. 
To change the blades, the material support must be removed. Release the four screws securing 
the blade clamps, remove blade clamps then withdraw the blades.  
It will be noticed that the arm blade is smaller than the body blade.  
This  safeguards  incorrect  assembly  when  inserted  carrier  blades  are  used.  Also  notice  the 
safety peg, there is a safety slot in the arm blade to prevent incorrect positioning.
