DESCRIPTION
WARNING
:
The balance of this tool is designed for horizontal use and is not ergonomically best
suited for all applications. Gage Bilt will be pleased to advise for your specific application.
The GB704 is a pneumatic-hydraulic tool designed specifically for the efficient installation of a wide range of blind
rivets. It weighs 4.30 lbs. (1.95kg) and can be operated in any position with one hand. It has a .540" (13.72mm) rivet
setting stroke and a rated pull load of 3300 lbs (14.68 kN) with 90 psi (6.2 bar) air pressure at the air inlet.
The GB704 riveter is designed to operate on a range of air pressure, with 90 to 100 psi (6.2-6.9 bar) providing the
maximum efficiency. At 90 psi (6.2 bar) air pressure, the GB704 does not exceed 81.5 dB (A) and consumes 3.9 cfm
at 20 cycles a minute.
The air inlet is provided with 1/4-18 female pipe threads to accept the users air hose fitting.
NOSE ASSEMBLIES ARE NOT FURNISHED WITH TOOL AND MUST BE ORDERED SEPARATELY. (See page 12 for

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 clean dry air supply set at 90-100 p.s.i. (6.2-6.9 bar) Max. equipped with a filter-regulator to prevent wear.
*Proper care by operator is necessary in maintaining full productivity and reducing downtime. Read all
applicable tool manuals and nose assembly data sheets prior to operating tools.
*Keep nose assemblies, especially jaws, clean and free of chips and debris. Lube jaws and collet surfaces that jaws ride
on with light machine oil on a daily basis.
*All Screwed End Caps, Base Covers, Air Fittings, Air Actuators, Screws and Nose Assemblies are to be examined at
the end of each working shift to check that they are secure.
*Check tool, all hoses and all couplings daily for damage or air/hydraulic leaks. Tighten or replace (if necessary).
*For a complete overhaul, tool kit GB704TK is recommended (see page 8).
WEEKLY MAINTENANCE
Keep the hydraulic system full (only use Dexron III or equivalent) and free of air by using the air bleeder assy
(704153) on a weekly basis. or as needed. (See Filling and Bleeding).
SEE TROUBLESHOOTING AND OVERHAUL FOR FURTHER GUIDANCE.
