DESCRIPTION
The GBP744E is a pneumatic-hydraulic tool designed specifically for the efficient installation of 1/4"
CHERRYMAX® & AllMax rivets, as well as a wide range of blind rivets. It weighs just over 7 lbs. and
can be operated in any position with one hand. It has a .580" rivet setting stroke and a rated pull load
of 3800 pounds on 90 psi air pressure at the air inlet.
The GBP744E riveter operates on a wide range of air pressure, with 90 to 120 psi providing the
maximum efficiency. At 90 lbs. air pressure, the GBP744E does not exceed 85 db (A) and consumes
6.5 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 ARE NOT FURNISHED WITH THIS RIVETER AND MUST BE ORDERED
SEPARATELY

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 90-120 lbs. 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 (51) 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 jaws ride on with light machine oil.
*For a complete overhaul, tool kit GBP740TK is recommended. It includes items 44-50
