SECTION A-A
The operator pushes the Tool's Nose over the end of
the fastener until the Tool's Puller bottoms on the fas-
tener. When the Tool's Limit Switch Rod makes con-
tact with the end of the fastener, the Limit Switch in
the back of the Tool is activated. When the trigger is
pressed, the rig receives a signal to swage the fastener.
The Piston moves back to start the swaging process.
After the fastener is fully swaged, the operator must
release the trigger, at which point the Tool's Anvil is
ejected off of the collar and the Tool is released from
the fastener.
