When the lever assembly 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 assembly, causing the piston to move to the rear of the head cylinder assembly. 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 assembly is released. Air pressure is then built up inside of the handle causing the valve spool assembly to
return to its original position and reversing the sequence directing air pressure to the rear of the head cylinder assembly, causing the
piston to move to the forward position.
