MAINTENANCE
WARNING:
Maintenance personnel
MUST
read and understand all warnings and cautions.
WARNING
:
Disconnect tool from its power source before performing maintenance.
WARNING
:
Excessive contact with hydraulic oil and lubricants should be avoided.
WARNING:
Dispose of Hydraulic Oil in accordance with applicable regulations.
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 psi. 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, 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 GB740TK is recommended.
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 GB704SH series are pneumatic-hydraulic tools designed specifically for the efficient installation of a wide range of blind rivets.
They can be operated in any position with one hand. They have a rated pull load of 3300 lbs. (14.68 kN) with 90 psi (6.2 bar) air
pressure at the air inlet.
The GB704SH and GB704SR riveters offer a unique “split” system providing the operator with an ergonomic tool with reduced hand
held weight, as shown below.
The GB704SH series riveters operate 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 GB704SH series 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.
NOSE ASSEMBLIES ARE NOT FURNISHED WITH TOOL AND MUST BE ORDERED SEPARATELY.
Daily cleaning and lubrication of nose assembly will greatly
reduce downtime and increase life of components. Using
sewing machine oil, or an equivalent cleaner/lubricant, follow
instructions below.
1. Disconnect tool vacuum line (if equipped).
2. Point nose assembly into oil as shown.
3. Cycle tool 8-10 times and wipe dry.

HYDRAULIC THREAD PREPARATION
IMPORTANT:
Be sure to use thread sealant on all hydraulic fittings, Loctite® 30534 or similar Teflon® infused pipe dope is
recommended.
CAUTION:
Teflon tape is an excellent thread sealer, however, if it is not 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.
CAUTION:
Over tightening can easily distort the threads.
