Principle Of Operation - Gage Bilt GB713 Original Instructions Manual

Table of Contents

When the air actuator assembly is depressed, the pressurized air inside of the tool is released allowing spring pressure to move the

valve spool assembly causing the air to be redirected. The air is directed to the top of the air piston assembly, moving it in a downward

direction. The air below the air piston assembly is then directed through the valve sleeve and exhausted out of the bottom of the tool.

Simultaneously, the piston rod assembly, connected to the air piston assembly, is also moving down, forcing hydraulic oil up and into

the front side of the head cylinder assembly, causing the piston to move to the rear of the head cylinder assembly. 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 air actuator assembly is released. Air pressure is then built up inside of the handle assembly causing

the valve spool assembly to return to its original position and reversing the sequence directing air pressure to the rear of the head

cylinder assembly, causing the piston to move to the forward position.
