PRINCIPLE OF OPERATION

When the tool is connected to a powerunit, operation is controlled by a actuator or switch in the handle. The

GB2480A incorporates an air actuator to send a signal; the GB2480 an electric switch. When the button 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 on the fastener pintail and pull the

sheets together. The anvil is forced over the collar, swaging it into the locking grooves of the fastener. Fur-

ther 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" fluid back to the powerunit tank. 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 spent pintail is

released and drops out the back of the tool.

HOW TO USE THE GB2480

WARNING:

OPERATOR

WARNING:

IT IS REQUIRED THAT EYE PROTECTION AND HEARING PROTECTION BE WORN DURING OPERA-

TION.

WARNING:

DO NOT PULL RIVET IN THE AIR. PERSONAL INJURY FROM FASTENER EJECTING MAY OCCUR.

#1. Set power supply to the recommended pressure, 8,400 psi (579.1 bar) for the pull and 3,200 psi (220.6 bar) for the

return.

#2. Connect hydraulic hoses and actuator line 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 from power supply.

#5. Select proper Nose Assembly

#6. Screw collet assembly onto piston.

#7. Slide anvil over collet. Slide retaining nut stop 240102 over anvil, secure nose using retaining nut 211102

(See proper data sheet for further instructions.)

#8. Re-connect to power supply.

WARNING:

BE SURE THERE IS ADEQUATE CLEARANCE FOR TOOL AND OPERATOR'S HANDS BEFORE

PROCEEDING. KEEP FINGERS CLEAR OF ANY MOVING PARTS. KEEP FINGERS CLEAR FROM
