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