Principle Of Operation - Gage Bilt GB740 Original Instructions Manual

Table of Contents

When the actuator 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, causing the piston assembly to move to the rear of the head cylinder. The internal components of the attached nose

assembly are also moving with the piston assembly to start the fastener installation. When the fastener installation is completed, the

actuator 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, causing the piston assembly to

move to the forward position.
