When the tool is connected to a powerunit, operation is controlled by the electric actuator. When the button is depressed, a directional

valve in the powerunit directs oil to the front side of the piston 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 button is released the directional valve reverses oil flow to the back of the piston and pushes the nose assembly off the

swagged fastener. The pintail ejector hydraulically pushes the spent pintail out of the nose assembly.
