pressure at the air inlet.
The GB784 riveter operates on a wide range of air pressure, with 90 to 100 psi providing the maximum efficiency. At 90 psi air
pressure, the GB784 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.
MAINTENANCE
WARNING

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. 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 bleeders (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.
*All Screwed End Caps, Base Covers, Air Fittings, Triggers, Screws and Nose Assemblies are to be examined at the end of each
working shift to check that they are secure.
*Check daily all Hoses, Couplings, and Tools for damage or air/hydraulic leaks. Tighten or replace (if necessary).
*For a complete overhaul, tool kit GB784TK is recommended.
