DESCRIPTION

The GBP7500A is a hydraulic installation tool capable of installing 1/2", 5/8" and 3/4" standard lockbolts.

It weighs 15 lbs and can be operated in any position with one hand. It has a 2.000" rivet setting stroke

and a rated pull load of 40,000 lbs.

The GBP7500A installation tool is designed to operate at pressures up to 10,000 psi on hydraulic

pressure developed by the Powerunit. Normal operating pressure is set at 10,000 psi PULL pressure and

6,000 psi RETURN pressure. The tool comes equipped with 24" hoses and electric cord kit complete

with quick disconnects.

NOSE ASSEMBLIES ARE NOT FURNISHED WITH THE TOOL AND MUST BE ORDERED SEPARATELY.

OPERATION

When the tool is connected to a powerunit, operation is controlled by a button in the handle. 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 onto the fastener

pintail and pull the sheets together. The anvil is forced forward, swaging the collar into locking grooves

of the fastener. Further 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.

MAINTENANCE

The performance of any tool depends upon good maintenance practices. Following these minimal

requirements for service and care will extend the life of your tool.

*Only use a hydraulic power source equipped with relief valves and pressures set within specified

limits.

*Keep hydraulic system free of dirt. Avoid letting couplers contact a dirty floor.

*Do not use as a hammer to force fasteners into holes or otherwise abuse tool.

*Proper care by operators is necessary in maintaining full productivity and reducing downtime.

WARNING

Be sure Powerunit is disconnected before cleaning, or when replacing worn or damaged components.

Severe personal injury may occur if power source is not disconnected.
