PLEASE CONTACT GAGE BILT FOR ALL OTHER SERIAL NUMBERS.
PRINCIPLE OF OPERATION
When the actuator is depressed, the pressurized air inside the tool is directed to the front side of the piston
thus moving it to the rear of the head ass’y, forcing the air from the back side of the piston to be exhausted
from the rear of tool. The internal components of the attached nose assembly are also simultaneously moving
with the piston to start the fastener installation. When the fastener installation is completed, the actuator is
released directing the air to the back side of the piston reversing the sequence.
HOW TO USE THE GB51
WARNING:
OPERATOR
MUST
READ AND UNDERSTAND ALL WARNINGS AND CAUTIONS.
WARNING:
IT IS REQUIRED THAT EYE PROTECTION AND HEARING PROTECTION BE WORN DURING
OPERATION.
WARNING:
DO NOT PULL RIVET IN THE AIR. PERSONAL INJURY FROM FASTENER EJECTING MAY OCCUR.
WARNING:
AIR IS EXHAUSTED FROM THE BACK OF THE TOOL. DIRECT THE BACK OF THE TOOL
(EXHAUSTED AIR) AWAY FROM OPERATOR, OTHER PERSONS WORKING IN THE VICINITY,
FOREIGN MATTER AND LIQUID.
CAUTION:
DO NOT USE BEYOND THE DESIGN INTENT.
The tool is shipped with a plastic plug in the air inlet connector. The connector has a 1/4-18 female pipe thread to accept
end-user air hose fitting. The tool comes with oil and is ready to use.
1. Remove plastic shipping plug from Handle (510322) and Install 1/4" air fitting into bottom of handle (510322).
Only use an air supply set at 90 psi (6.21 bar)-100 psi (6.89 bar) equipped with a filter-regulator to prevent
wear.
2. Connect air hose with 90 psi (6.21 bar) to tool (3/8 minimum diameter air line is mandatory, 90 psi (6.21 bar) is
recommended) and cycle tool a few times by depressing and releasing actuator. (Clean dry air is mandatory).
WARNING:
ENSURE AIR HOSE IS SECURELY CONNECTED TO AVOID POSSIBLE HOSE WHIPPING.
3. Disconnect air hose from tool.
4.
Select proper Nose Assembly, screw collet and anvil onto the tool and attach securely. (See proper data sheet for
further instructions.)
5.
Connect air supply.
6. To install screw-on pulling head: While keeping internal components of pulling head forward in the nose
assembly start threading in the anvil holder, continue threading in until internal component starts to thread
onto the drawbolt (510217). Thread nose assembly in until nose assembly bottoms out. After nose
assembly is completely threaded onto tool, back off nose until flat is in the desired position and tighten
locknut. For nose assemblies with a pintail ejection slot we recommend locating it down so used rivet
stems fall out of the nose assembly by gravity.
7.
Insert rivet into Nose Assembly and the application then depress actuator. Upon releasing the actuator the stem will
eject out the rear of nose assembly.
8. Always hold tool so pulling head is perpendicular to surface of material in which rivet is being installed.
Exert firm pressure against rivet during installation.
WARNING:
ALWAYS DISCONNECT AIR SUPPLY WHEN TOOL IS NOT IN USE TO PREVENT ACCIDENTAL
START-UP.
