PRINCIPLE OF OPERATION

 

When the actuator lever assy is depressed, the pressurized air inside of the tool is released allowing spring 
pressure to move the valve spool assy causing the air to be redirected. The air is directed to the top of the air 
piston assy, moving it in a downward direction. The air below the air piston assy is then directed through the 
valve sleeve and exhausted out of the bottom of the tool. Simultaneously, the piston rod assy connected to 
the air piston assy is also moving down, forcing hydraulic oil up and into the front side of the head cylinder 
assy,  causing  the  piston  to  move  to  the  rear  of  the  head  cylinder  assy.  The  internal  components  of  the 
attached nose assembly are also moving with the piston to start the fastener installation. When the fastener 
installation is completed, the actuator lever assy is released. Air pressure is then built up inside of the handle 
causing  the  valve  spool  assy  to  return  to  its  original  position  and  reversing  the  sequence  directing  air 
pressure to the rear of the head cylinder assy, causing the piston to move to the forward position.
