PRINCIPLE OF OPERATION
When the actuator lever assy is depressed, the pressurized air inside 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 side 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 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 oil from the rear of the head
cylinder assy is directed to the top of the piston rod assy 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 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.
