The GB745 is a pneumatic-hydraulic tool designed specifically for the efficient installation of a wide range of blind rivets, lockbolts
and MAGNA-GRIP® fasteners. It weighs just over 7 lbs. (3.26 kg) and can be operated in any position with one hand. It has
a .620" (15.75 mm) rivet setting stroke and a rated pull load of 6300 lbs (28.02 kN) with 90 psi (6.2 bar) air pressure at the air inlet.
The GB745 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. (6.2bar) air pressure, the GB745 does not exceed 81.5 db (A) and consumes 6.0 cfm at 20 cycles per minute.
The air inlet is provided with 1/4-18 female pipe threads for accepting the user's air hose fitting.
Nose Assemblies that were designed for the model 353 installation tool mount directly on the GB745 without the use of an adapter.
Nose Assemblies that were designed for the model 352 installation tool will attach to the GB745 with the use of the 353352 nose
assembly adapter.
NOSE ASSEMBLIES ARE NOT FURNISHED WITH THIS TOOL AND MUST BE ORDERED SEPARATELY (SEE PAGE 12).
MAINTENANCE
WARNING
:
EXCESSIVE CONTACT WITH HYDRAULIC FLUID AND LUBRICANTS SHOULD BE AVOIDED.
WARNING:
MAINTENANCE PERSONNEL
MUST
READ AND UNDERSTAND ALL WARNINGS AND CAUTIONS.
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 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 ass’y
(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 surfaces that jaws
ride on with light machine oil on a daily basis.
*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 GB745TK is recommended.
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!
