PRINCIPLE OF OPERATIONS
When the actuator is depressed, the throttle valve is shifted, directing the pressurized air inside the tool to the bottom of the air
piston assembly, moving it in an upward direction. The air above the air piston assembly is then directed out the exhaust, on
the bottom of the tool. Simultaneously, the piston rod assembly connected to the air piston assembly is also moving up, forci ng
hydraulic oil up and into the front of the cylinder, causing the piston assembly to move to the rear of the cylinder. The oil from
the rear of the cylinder is directed to the bottom of the piston rod assembly, inside the handle assembly. The internal components of
the attached nose assembly are also moving with the piston assembly to start the fastener installation. When the fastener installation
is completed the actuator is released allowing spring pressure to move the throttle valve to shift, directing the air pressur e to
the top side of the air piston assembly and reversing the sequence.
