CLEANING AND LUBRICATING PROCEDURE
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 (Fig. A).
3. Cycle tool 8-10 times and wipe dry.
DESCRIPTION
WARNING
:
The balance of the tool is designed for horizontal use and is not suited for any other application. Gage Bilt will
be pleased to advise for your specific application.
The GB744 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. (3.2 kg) and can be operated in any position with one hand. It has
a .580" (14.73mm) rivet setting stroke and a rated pull load of 3,800 lbs. (16.9 kN) on 90 psi (6.2 bar) air pressure at the air inlet.
The GB744 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. (6.2 bar) air pressure, the GB744 does not exceed 81.5 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. (See page 12 for nose
assembly recommendations.)
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 all environmental regulations applicable in your area.
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 lbs. (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 (only use Dexron III, or equivalent) and free of air by
using the air bleeder (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.
