HYDRAULIC DIAGRAM
When the tool is connected to a powerunit, operation is controlled by an electric actuator / air actuator in the handle. When the electric
actuator is depressed, a directional valve in the powerunit directs oil to the front side of the piston assembly forcing it and the nose
assembly collet rearward. 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 electric actuator / air actuator is released the directional valve reverses oil flow to the back of the piston assembly and
pushes the nose assembly off of the swaged fastener. The pintail will eject from the deflector once next fastener is installed.
