When the tool is connected to a hydraulic powerunit, operation is controlled by an electric actuator (GB3585) or a piloted air actuator
(GB3585A) in the handle. When the actuator is depressed, a directional valve in the hydraulic powerunit directs oil to the front side of
the piston forcing it and the internal component in the nose assembly rear-ward. This action causes the jaws to clamp onto the fastener
pintail and pull the sheets together. The anvil is forced forward, swaging the collar into locking grooves of the fastener. Further force
breaks the pintail off, approximately flush with the collar. When the piston is in the rear position flats are exposed unloading the
pressurized oil.
When the actuator is released, the directional valve directs the oil to the back of the piston pushing the nose assembly off of the
swaged fastener. The pintail ejector hydraulically pushes the spent pintail out of the nose assembly. When the piston is full forward
pressure is built shutting of the hydraulic powerunit.
