PRINCIPLE OF OPERATION

 

When the trigger is depressed, the pressurized air inside the tool is released allowing spring pressure to 
move the valve spool, causing the air to be redirected.  The air is directed to the top side of the air piston, 
moving it in a downward direction. The air below the air piston is then directed through the valve sleeve and 
exhausted out of the bottom of tool. Simultaneously, the piston rod connected to the air piston is also moving 
down, forcing hydraulic oil up and into the front side of the cylinder head, causing the piston to move to the 
rear of the cylinder head. The oil from the rear of the head cylinder is directed to the top of the piston rod 
assembly inside the power cylinder. 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 trigger is 
released. Air pressure is then built up inside of the handle causing the valve spool to return to its original 
position and reversing the sequence.
