range of blind rivets and lockbolts. It weighs 6.5 lbs. and can be operated in any position with one hand.
It has a .775" rivet setting stroke and a rated pull load of 4500 pounds with 90 psi air pressure at the air

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.

*The tool will eventually lose some hydraulic oil. Keep the hydraulic system full and free of air by
using the air bleeder (745163) on a regular basis.

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.
*For a complete overhaul, tool kit GBP745CTK is recommended.
