PRINCIPLE OF OPERATION
When the tool is connected to a powerunit, operation is controlled by a button in the handle. When the but-
ton is depressed, a directional valve in the powerunit directs fluid 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. Fur-
ther force breaks the pintail off, approximately flush with the collar.
When the button is released the directional valve reverses fluid 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.

#1. Set power supply to the recommended pressure, 7,400 psi (510.2bar) for the pull and 3,200 psi (220.6 bar) for the
return.
#2. Connect hydraulic hoses and electric cord to power supply.
WARNING:
ENSURE HYDRAULIC HOSES ARE SECURELY CONNECTED TO AVOID POSSIBLE HOSE
WHIPPING.
#3. To ensure piston is in the full forward position, Cycle tool.
#4. Disconnect electric cord from power supply.
#5. Select proper Nose Assembly
#6. Screw collet assembly onto piston until top of collet flat lines up with top of tool.
#7. If Collet Lock is not in Piston groove, continue to turn 1/4 turn, or less until lock engages groove.
#8. Tighten Set Screw.
#9. Slide Anvil over assembled over Collet. Install split ring, sleeve and retaining ring (furnished with tool).
(See proper data sheet for further instructions.)
#10. Re-connect electric cord into power supply.
