DESCRIPTION

The GB786/204 Split Riveter Pneumatic-Hydraulic Installation Tool is designed specifically for the efficient

installation of a wide range of blind rivet and lockbolt fasteners. This tool's unique "split" system provides

the operator with a lightweight ergonomic tool for a fraction of the cost of other cumbersome power rigs. It

has a .500" (12.7mm) rivet setting stroke with a rated pull load of 5200 lbs. (23.1 kN) at 90 psi. (6.2 bar) air

pressure at the air inlet.

The GB786/204 comes with 8 ft. of hose and a remote actuator. The GB204 cylinder when held in your hand,

weighs just 2.0 lbs (0.91 kg)! while the entire split riveter weighs 19 lbs (8.61 kg).

The GB786/204 Split Riveter operates on a wide range of air pressure, with 90 to 100 psi. (6.2-6.9 bar)

providing maximum efficiency. At 90 psi. air (6.2 bar) pressure in the GB786/204 does not exceed 81.5 dB (A)

and consumes 6.0 cfm at 20 cycles a minute.

This tool accepts all patented GB204 style nose assemblies.

MAINTENANCE

WARNING:

EXCESSIVE CONTACT WITH HYDRAULIC OIL AND LUBRICANTS SHOULD BE AVOIDED.

WARNING:

MAINTENANCE PERSONNEL

WARNING:

DISCONNECT TOOL FROM ITS AIR SOURCE BEFORE PERFORMING 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 an air supply set at 90-100 psi. (6.2-6.9 bar) equipped with a filter-regulator unit to prevent wear.

*The tool will eventually lose some hydraulic oil. Keep the hydraulic system full and free of air by using the

air bleeder assy (704153) on a regular basis.

*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 surface

that jaws ride on with light machine oil.

*Check tool, all hoses and all couplings daily for damage or air/hydraulic leaks. Tighten or replace (if necessary).

*A complete overhaul can be achieved by the use of Service Kit 786204 which contains a complete

set of o'rings, back-up rings, screws, washers and gasket.

HYDRAULIC THREAD PREPARATION

IMPORTANT:

Be sure to use thread sealant on all hydraulic fittings, Loctite® 30534 or similar Teflon® infused pipe

dope is recommended.

properly applied, pieces of Teflon may enter the hydraulic system and cause malfunction or damage.

Use 1 1/2 wraps of tape on each thread. Cut off all loose tape ends. Tighten until fitting feels snug and

then go 1/2 to a full turn past that point.

WARNING:

This tool incorporates a patented

hydraulic relief valve. When overhauling

tool, o'ring (A-287), back-up ring (401101),

retaining ring (400936) and spring (50806)

must be replaced. Failure to do so could

result in SEVERE PERSONAL INJURY!
