The nose assembly is placed over the end of the fastener
until the tool's puller bottoms on the fastener. When the
trigger is pressed, a solenoid‐operated valve in the powerig
directs pressurized hydraulic fluid through the PULL hose to
the rear side of the piston and allows fluid on the RETURN
side to flow back to the tank. The piston moves forward to
start the swaging process.
After the fastener is fully swaged, the trigger must be
released, at which point the solenoid is de‐energized and the
valve directs pressurized hydraulic fluid to the front side of
the piston and allows fluid on the PULL side to flow back to
the tank. This causes the piston to move back while pushing
the anvil off of the swaged collar, releasing the tool from the
fastener.
