Principle Of Operation - Gage Bilt GB510NAS Instructions Manual

When the tool is connected to a powerunit, operation is controlled by a actuator to the hydraulic hoses. The GB510ANAS incorporates
an air actuator to send a signal; the GB510NAS 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 unloading 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.
