PRINCIPLE OF OPERATION
When the actuator lever assy is depressed, the pressurized air inside of the tool is released allowing spring pressure to move the
valve spool assy causing the air to be redirected. The air is directed to the top of the air piston assy, moving it in a downward
direction. The air below the air piston assy is then directed through the valve sleeve and exhausted out of the bottom of the tool.
Simultaneously, the piston rod assy connected to the air piston assy is also moving down, forcing hydraulic oil up and into the front
side of the head cylinder assy, causing the piston to move to the rear of the head cylinder assy. The internal components of the
attached nose assembly are also moving with the piston to start the fastener installation. When the fastener installation is completed,
the actuator lever assy is released. Air pressure is then built up inside of the handle assy causing the valve spool assy to return to its
original position and reversing the sequence directing air pressure to the rear of the head cylinder assy, causing the piston to move to
the forward position.
HOW TO USE THE GB752SH
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 bottom of the too. Direct bottom 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 Swivel (A-249) and screw in your air fitting.
2. Attach Deflector (752122) to rear of Head Cylinder Assy (752120).
WARNING:
Rotate deflector away from operator and other persons working in the vicinity.
.
3. Connect air hose with 90 psi. (6.2 bar) to tool (3/8 minimum diameter air line is mandatory, 90 psi. (6.2 bar) is recommended) and
cycle tool a few times by depressing and releasing actuator lever assy. (Clean dry air is mandatory).
WARNING:
Ensure air hose is securely connected to avoid possible hose whipping.
4. Disconnect air hose from tool.
5.
Select proper Nose Assembly, screw collet and anvil onto the tool and attach securely. (See proper data sheet for further
instructions.)
6.
Connect air supply.
7.
Insert rivet into Nose Assembly and the application, then depress actuator lever assy. Upon releasing the actuator lever assy the
stem will eject to the rear of the tool.
WARNING:
Always disconnect air supply when tool is not in use to prevent accidental start-up.
