PRINCIPLE OF OPERATION
When the 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 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, simultaneously releasing the
spent pintail from the nose assembly, allowing it to be vacuumed into the pintail collection bottle.
