When the tool is connected to a powerunit, operation is controlled by an actuator or switch attached to the hydraulic hoses. The

GB206-500/25A incorporates an air actuator to send a signal; the GB206-500/25 an 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 on the fastener pintail and pull the sheets together. The anvil is forced over the collar, swaging it into locking

grooves of the fastener. Further force breaks the pintail off, approximately flush with the collar.

When the piston nears the end of its stroke it exposes flats on the back of the relief valve. These flats "dump" oil back to the powerunit

tank. When the button 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 spent pintail is released and drops out the back of the tool.
