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 assy 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.
