When the actuator 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 side 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 oil
from the rear of the head cylinder assembly 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 actuator lever assembly is released. Air pressure is then built up inside of the handle assembly causing
the valve spool assembly to return to it
