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