Principle Of Operation - Gage Bilt GB2620PT Original Instructions Manual

When the installation tool is connected to a powerunit, operation is controlled by an electric actuator (240122) (GB2620PT) in the handle.
When the actuator 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 actuator is released the directional valve reverses oil flow to the back of the piston and pushes the nose assembly off of
the swaged fastener. The pintail ejector hydraulically pushes the spent pintail out of the nose assembly.
