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 GB743 is a pneumatic-hydraulic tool designed specifically for the efficient installation of a wide range of blind rivets. It weighs
6.25 lbs. (2.83 kg) and can be operated in any position with one hand. It has a .900" (22.86mm) rivet setting stroke and a rated pull load
of 4000 lbs. (17.8 kN) with 90 psi (6.2 bar) air pressure at the air inlet.
The GB743 riveter operates on a wide 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 GB743 does not exceed 81.5 dB (A) and consumes 3 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.
UNLESS ORDERED RIVET SPECIFIC (I.E. GB743/8N), THE STANDARD GB743 IS FURNISHED WITH NOSE ASSEMBLY 8N-743-24 AND

MAINTENANCE
WARNING:
Maintenance personnel
MUST
read and understand all warnings and cautions.
WARNING
:
Disconnect tool from its power source before performing maintenance.
WARNING

WARNING:
Dispose of hydraulic oil in accordance with all environmental regulations applicable in your area.
WARNING:
Read MSDS documents for all applicable materials.
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 p.s.i. (6.2-6.9 bar) equipped with a filter-regulator to prevent wear.
*The tool will eventually lose some hydraulic oil. 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.
*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).
