PRINCIPLE OF OPERATION
When the actuator assy
-
air 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 assy
-
air 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.
